The permanent increase in prices for diesel fuel makes many car owners think about the question of the possibility of installing HBO on diesel engine His cars. Purely technically do it quite really, but the solution of this task is based on two serious doubts:
- Will it be appropriate in terms of savings
- Whether it will require re-equipment of making irreversible changes to the engine design, as far as it reduces its resource and reduce the general specifications car
After receiving the answers to these questions, the owners of the car will be able to decide whether they should alter the engine of their car from a diesel engine or better and more profitable to leave everything as it is.
Fuel ignition, in a diesel engine, occurs in the combustion chamber due to the injection of it under pressure in compressed air.
Therefore, two technical solutions are currently used, allowing us to put ordinary gas equipment on any diesel engine. The difference between them is principled:
There are also factory models of gas distribution on methane. For example, Volvo (Volvo) FH / FM and KAMAZ 5490 NEO with Mercedes-Benz power installation. But such cars have not yet been widely used.
Principle of operation of the gas dial engine
The transition to the gas fuel is carried out using a switch from the car's cabin after the engine warming up, or automatically. The gas supply process is controlled by an electronic control unit of the GBO installation control.
The gas on the diesel engine is supplied dosed with the intake manifold. Where mixing with air, in the intake tact, it enters the cylinders through inlet valves. Then in a compressed piston gas-high mixture (compression tact), diesel fuel is sprayed, where the explosion occurs due to pressure and temperature. D / t here it acts as a mockery, as the gas ignition temperature is above the diesel fuel and he himself cannot ignite.
Fuel types that can consume diesel for gas
Redo the motor on the double fuel system can only be under the specific type of gas. Either it will be.
Make a diesel on methane is more expensive, but it will work with the best economic effect than the option with propane. In addition, methane is cheaper. When applying propane to diesel, the contribution to the total fuel consumption will not exceed 30-50%. But the share of consumption of the methane component can be increased to 80%. It all depends on the regime the work of the DVSWhere are taken into account:
- car speed;
- season (summer, winter);
- terrain relief (mountain, plain);
- pressure and gas temperature;
- with turbocharged diesel or not.
Advantages and disadvantages of translating diesel for gas
The main advantage of the installation of HBO for methane, or propane-butane mixture to the diesel engine is to reduce fuel costs from 10-50%. Moreover:
- there is an increase in efficiency, a motor resource. At the same time, power and torque remain the same, or increase, in some cases, by 5-25%;
- increased service life fuel system 1.5-2 times (large plus for systems COMMON RAIL.);
Reduce harmful emissions exhaust (smoke); - gas engine runs softer, its noise is reduced;
- lowering nagar, deposits in cylinders, combustion chambers, sump filters;
- reduced replacement costs;
- mileage is increasing with two-fuel motion mode;
DVS alterations are not required.
Of the serious flaws:
- high cost of re-equipment;
- increase time and maintenance costs, setup, system repair;
- search, reducing the useful volume due to them;
- increased vehicle weight.
With improper compliance with the technology of re-equipment, (for example, incorrect installation or no temperature sensor on the exhaust manifold) can noticeably increase the wear of the power plant. Since in the combustion chamber and exhaust system In the explosion of the gas-air mixture and diesel fuel, high temperature begins to form.
Diesel vehicles that can be converted to gas diffuss
Any engine on the diesel population can be removed under the use of gas as an additional component. It does not matter which type of fuel system is used basically, the high-pressure mechanical fuel pump (TNVD), the pump-nozzle or ramp / rack "Common Rail". Also S. onboard network 12/24 V. With turbine or atmospheric.
At the same time, the costs of modernization of the passenger car will be significantly less than the traffic rework costs truck, due to the number of cylinders installed, fasteners and to them or valves in the case of methane. Also for engines with a large volume apply 2.
But independently, it is necessary to put a HBO for diesel trucks, passenger transport or agricultural machinery (tractors and other), with a proper approach, the economic effect will be obvious.
Is it possible to translate diesel for gas with your own hands
Put everything yourself additional devices It is impossible for a diesel power unit without the presence of a serious instrumental base in a personal subsidiary farm, or a garage. The most time-consuming operations are:
- Connecting gas equipment.
- Adaptation / synchronization of the standard fuel system.
- Installation of control and measuring equipment and electronics.
In addition, special will need software for. But in the presence of great desire, the re-equipment is possible.
It is important not to forget about the mandatory additional fuel InstallationWhat is not a quick procedure. Where appropriate documents from the service station will also need.
Cost of re-equipment for freight and passenger cars
Average prices for a complete set of equipment, taking into account the cost of fuel cylinders for passenger cars It begins from 50 thousand rubles, and for freight and passenger vehicles - HBO can cost from 100 to 500 thousand rubles.! (everything is selected individually). Installation of equipment in a specialized company costs from 15-30 thousand rubles. The final price also needs to include the costs of legalization of changes made.
Modern cars unpredictable in terms of quality and resource operation. We are accustomed to the fact that the machines of eminent brands serve for years without problems, hundreds of thousands of kilometers are passing without significant difficulties. But today information on significant defects of a particular technology appear increasingly. Which means that all more cars Do not buy on the market new vehicle. Skandal with diesel units volkswagen. Passed all over the world extremely tense. Environmental norms of motors were violated, the concern tried to deceive verifying organizations and buyers. The result of such an unpleasant moment is a drop in ratings and a decrease in trust in the brand. For example, in the US, sales VW and Audi fell more than half the last year. Even in Germany, cars of the Volkswagen concern received much less sales in the total market share. Today we will talk about the diesel directions of this concern from the point of sight of the conditions of Russian operation.
I wonder why the diesel scandal did not affect Russia? Those most engines that came under the sight of ecological services around the world were actively supplied in the Russian Federation. These are 2-liter diesel units of almost all types that are installed on Skoda, VW, AUDI and SEAT. In Russia, this Skoda Octavia., VW Passat, Caddy, Tiguan and other models. But in our realities, the demand for diesel engines only grew, as they have become more affordable. If earlier diesel units were not intended for Russia and cost expensive, today they fell in price due to a serious reduction in demand all over the world. Accordingly, the question arises how safely the diesel engine from Volkswagen is to buy. Today we will consider all aspects of a heavy fuel engine and give recommendations about the acquisition. Of course, this does not apply to those buyers who are experiencing about the ecology of their car on the norms of Euro-6.
The resource of engines on the diesel - why is it above?
If you look at gasoline options power plants, I will be surprised by one simple truth - their resource has declined significantly. 10 years ago good engine It could easily take up to 300,000 km, and then after repair to drive another 200,000 km. Today, the resource of TSI aggregates with turbines is 150,000 km in total, and the repair motors are often not subject to repair. In addition, immediately after the warranty period is completed, a lot of problems with a turbine begins. Diesel benefits are the following:
- the design is classical, in turbocharging technologies and production of the main parts, the corporation did not introduce any serious experiments, so the diesel is more reliable and simple;
- motors are repaired, so after the completion of the resource can be safely held overhaul, establish new factory details and extend the life of the car;
- electronics easier and more reliable, it is also classic and without significant experiments, as in the case of engine TSI on gasoline, nothing breaks and does not require replacement;
- driver reviews prove that a resource of 300,000 km run is overcome on German diesel engines very easily, this figure is achieved without repairs and additional investments;
- during the production there is no downce task, since the diesel unit throws about the same amount of harmful substances in fact with any volume of fuel combustion chambers.
A few years ago automotive experts And engineers saw the real future in diesel installations. On their basis, hybrids were developed, the technologies have improved. But the scandal with VW changed everything, and today these motors have become expensive, the concerns are trying to get rid of them and move on electricity. However, for Russia, so far it is a good opportunity to purchase a cheap machine with excellent potential. So it's not worth waste time.
What good in diesel engines from VW?
The corporation suggested quite simple from a technical point of view of the motors. They don't have an incredible superior, there are no difficult electronic blocks. It makes motors more reliable, deprives the chances of an expensive breakdown. Also, the engines have proven themselves in frosts in the context of the Russian North. Here and gasoline engines survive often for long, and diesel engines and are not afraid of such temperatures. You can highlight a few common advantages for all modern TDI models:
- efficiency - power units consume about 7 liters of fuel per 100 km run in mixed cycleAt the same time, we are not talking about a small-caltry, but about the large passat d-class sedan;
- in its assets, the installation has a simple turbine, which creates excellent opportunities for overclocking power, with 2 liters, the company receives from 105 to 180 hp, and this is with factory restrictions;
- many use these tuning engines, even a banal chip tuning without changing the design gives up to 200 power horses, Stage 2 will give even more without reducing the resource;
- endurance - even with constant promotion to high revolutions and high-speed modes Operating this installation can live long and do not upset the owner expensive repair;
- ease of use - due to a number of technologies, VW corporation managed to make a diesel convenient, it is not necessary to get used to it and adapt, no about special differences From gasoline engines.
It is these advantages that became the basis for thinking about buying a diesel engine for many Russians. Oils in the fire poured prices. It is also possible that in the near future secondary market There will be a flood of excellent transport from Europe. This is due to the fact that in European countries a ban is introduced for entry diesel cars to central parts of cities. Of course, this will cause the sale of machines on heavy fuel at random prices, and they can get to Russia.
Are there any deficiencies in folkswagen diesel units?
Today, objectively the advantages of these engines are more than flaws. Nevertheless, it is worth remembering some nuances that are constantly in response. It is no secret that heavy fuel installations saves money only to its first owner who bought the car in the cabin. Used cars with 10 years of travel experience in russian conditions No longer will provide most of the advantages mentioned above. But there can be a lot of minuses in such engines:
- Service cost. On average, the price of regular maintenance It turns out 2 times higher than when carrying out the same in power and class of the gasoline engine of the same concern.
- Requirements for fuel. If you board a poor-quality diesel fuel in the tank, you will have to clean the system from pollution. It will also cause the refusal of all car systems on the road and the need for overpayment for the tow truck.
- Masputability. Pour in a row to pour unsuitable oils several times to get maximum wear with piston wear, as well as subsequent costly repairs.
- Prices for spare parts. Accessories for diesel engines are traditionally more expensive, but this minus can become irrelevant soon, since the market is flooded with these installations and spare parts.
- Vibration. When running more than 100,000 km, even the most elite cars with such aggregates begin vibrations and other troubles. This is due to the nature of such engines.
In each case, you have to risk something to get certain benefits. When buying a gasoline motor, you risk a resource to get power and comfort. In the case of a diesel engine, you will get much less horses, but more fuel savings, a significant improvement in the indicators of a common resource and efficiency. But at the same time, service costs and certain risks of specific breakdowns will increase. Therefore, the decision to take on its own priorities.
What will happen in the future with diesel installations from VW?
As the concern himself says, already in 2020 an active presentation of electric vehicles will begin. Already until 2025, the company's plans to completely replace the machines on liquid fuel with electric cars. This applies not only to the Folskwagen brand, but also all the brands in the concern. This is connected not only with the scandal in the United States, but also with the objective need to search for alternatives to gasoline and diesel. The norms of ecological standards euros will only increase, and soon they will become unbearable for aggregates.
In the fate of diesel engines today there are several obvious facts:
- if the company does not find a way to make engines more environmentally friendly, this year will be replaced by gasoline versions, the production of diesel engines will lose greatly;
- in Russia, such installations will continue to be supplied, since here they are gaining momentum due to low cost, efficiency and good resource, we approach the choice of the car practical;
- after 5 years, the production of DVS can be stopped at all, all motors on liquid fuel can be replaced by electric motors, but so far there are a number of barriers to such events;
- obviously, the company will not invest billions in the development of diesel power aggregates, sales markets remained not the most attractive, so there will be no investment;
- but support for car owners will remain unchanged, Volkswagen will continue to produce parts and the engines themselves for replacement a few more years after the installation is completed on new cars.
As you can see, the era of diesel engines is suitable for its completion. It is possible that in the near future all global concerns will begin to refuse such installations. With the introduction of Euro-7 standards, which are now in development, no motor in heavy fuel will be able to certify. Companies will have to be trembling and risking or simply refuse to produce such technologies.
We offer to watch video with information about Diesel Installs VW:
Let's sum up
Volkswagen Corporation Cars - Dear Class in Russia. Today, the demand for all aggregates was leveled, buyers no longer prefer blindly gasoline engines, as they know about their subtleties and possible problems In operation. Diesel installations received due attention to the Russian Federation after they went to the sunset in Europe. Contributed to raising demand some important factors, such as price reduction and good feedback owners. If you buy a new diesel engine, then about 300,000 km can not worry about possible problems and disadvantages of its operation.
However, there are deficiencies in heavy fuel units. The problems consist in the fact that such technologies are too thin, they are sensitive to factors of poor-quality service or not the best fuel. Therefore, it is not necessary to talk about the absence of trouble. VW specialists themselves recognized that today they lose the meaning of development in the direction of engines internal combustion. All investments are sent to a new sphere of electric vehicles, and heavy fuel units, as well as on gasoline, simply receive the necessary versions to fit into existing environmental standards. So the choice remains yours. What do you think about the Diesel units of Volkswagen?
In one of our materials, we talked about the specifics of the operation of diesel engines in the Russian conditions.
If you decide that you can be a "dieselist", you need to find out if there is an economic meaning in this. Any other arguments "for" and "against" diesel - to the side. Today we consider only money.
Price of car
Comparison of the cost of ownership of gasoline and diesel modifications of one model begins with the analysis of their price. There is a rash stereotype that the diesel modification is always more expensive. Indeed, diesel engines are made of more high-strength and expensive materials, and their fuel equipment is very expensive. In addition, all modern diesel engines are equipped with an intermediate cooling turbocharged, and the turbine and the intercooler radiator also costs it is not suiced.
Therefore, if an alternative to the diesel is equal to the volume and quantity of cylinders, a gasoline non-vulgar motor, diesel will be significantly more expensive. For example, for Citroen C4, the surcharge for a 1.6-liter diesel compared to the gasoline atmospheric of the same litter is 85,000 rubles. At the price of the gasoline version in a million with a little "is a lot.
If equal to the volume and number of cylinders, the gasoline motor also stuffed high technologies - Direct fuel injection and turbocharged, its price is close to the diesel. For example, a two-liter diesel BMW X3 is only 30,000 rubles. It is more expensive than its "turbobenzine" fellow. On the background of 3,000,000 rubles. This difference is completely invisible.
And it happens so that an alternative to a gasoline motor is a diesel engine of much smaller litter with fewer cylinders. In this case, the diesel version will be cheaper. For example, for diesel Land Cruiser Prado. With a 2.8-liter "four" asking for 247,000 rubles. Less than gasoline with four-liter V6 in equal configuration.
Although in some cases the difference in price between gasoline and diesel modifications has no logical explanation and is the result of marketing games. Depending on the interest in sales of a certain engine in Russia, the automaker can establish both an attractive and barrier-high price.
For example, Diesel Mitsubishi Pajero. IV has recently cost 500,000 rubles. more than gasoline. So that the diesel "Four" was half a million more expensive than gasoline V6 close volume, the latest version should be sold at all without a motor ... It is not surprising that the supply of diesel pajero was discontinued due to the "lack of demand" ...
Thus, diesel modification can cost both more and cheaper than gasoline. It depends on the specific model under consideration.
Diesel 245-strong Porsche Cayenne. The dynamics significantly inferior to a gasoline 420-strong "ESK", while in demand. Even for buyers such cars more low price Diesel, plus savings on insurance, taxes and fuel matters.
Compact carcases of diesel engines are much more expensive than gasoline engines. Therefore, it can be economically justified only in a taxi and courier service, where cars are huge annual runs And they can refuel on cards only on proven gas stations. But even the very "treser" car - Logan diesel modification in Russia is not ...
At first glance, Diesel Touareg is noticeably more expensive than a gasoline version, but he has much richer basic equipment. Therefore, when you start to retrieve the gasoline machine options, the difference in price between them is significantly reduced.
Before the departure of the Diesel Grand Cherokee from Russia, the price difference between it and the gasoline 3,6-liter motor was significantly more than in Europe. Apparently, in the representation of "Chrysler" did not really want it to sell ...
Unexpected expenses
In another article, we found out that diesel engines are extremely demanding on the quality of fuel, and their repair is very expensive. However, this does not mean that gasoline modification will be more reliable. For example, many European automakers diesel engines even on our fuel are quite a survival, and high-tech gasoline engines are already in warranty period Repair and change packs ...
But if a serious problem is found behind the gasoline engine, the automaker in the warranty period usually eliminates it for free, without trying to navigate on the quality of fuel. If Diesel refuses, the first thing for the fuel sample from the tank is sent to the examination. And if at least one parameter does not meet the requirements of the automaker (most often it happens), repair even in the warranty period is made at the expense of the client.
Well, well, if the warranty for diesel fuel equipment is in general. Some automakers, not trusting the quality of Russian diesel fuel, refer to it in the warranty book section "What the factory guarantee does not apply." As far as correct and legally, the question is separate. But the probability of laying out of your pocket 100 000-200 000 rub. The repair of a diesel engine is incomparable higher than on the repair of a gasoline motor.
Optional equipment
As we have said, some diesel engines in the cold have poorly warming the salon. If the machine from the factory is not equipped with a fever of the air entering the interior, you may have to install "autonomy", an up-to-date enabled mode.
In principle, it can be installed on the gasoline version. But if there are not enough "cold" gasoline engines so far (although recently also began to appear), then for diesel engines "Autonomy" is often the need for a whim of the owner. Therefore, 70,000-90,000 rubles should be ready to add to the cost of a diesel car.
In addition, in the Russian conditions, a heated fuel separator is very useful to establish a heated separator. It is about 15,000 rubles.
Casco.
As you know, the Casco tariff is considered as a percentage of the car's cost. Accordingly, if a diesel modification is more expensive than gasoline, for the policy every year will have to pay more if cheaper - less.
True, sometimes the tariff for diesel and gasoline modifications is different. For example, the hijacious Prado is interested in attackers only with a diesel engine, so some insurers have tariffs for a gasoline version below. But it is rather an exception to the rules.
Transport tax
Currently, the magnitude transport tax Depends on the power of the engine. Most often, the power of the diesel engine is comparable or somewhat less than that of an alternative gasoline engine. Accordingly, it is necessary to pay for diesel about as much or slightly less. Although, for example, for Land Cruiser Prado, this is not at all a "somewhat". If for a 282-strong "gasoline" by the state every year it is necessary to "enter" 42,300 rubles, then for 177-strong diesel - only 8,850 rubles. Feel the difference…
Maintenance
Mortar about the high cost of servicing diesel engines is supported by the fact that people confuse planned maintenance with repair.
Yes, repairing diesel is really expensive. But this is a lottery, which is possible, but not necessarily obligatory. Some are driving on a diesel engine of 150,000-200,000 km and manage to sell the car without putting a penny to repair a motor.
In addition, it is not at all that an alternative gasoline engine will be more reliable. For example, many German automakers diesel engines even on our fuel are completely survivors, but "petrol" even in the warranty period are repaired in a massive order. As for the cost planned service, Diesels and gasoline engines are comparable. The replacement of the fuel filter on the first is equalized by the replacement of the spark plugs on the second, and otherwise they are almost the same.
Diesel can be more expensive in service only if the interservice interval is less than that of a gasoline engine, or the owner voluntarily reduces it (which is very useful in our conditions). But if you make three additional oil replacements for 100,000 km and two additional replacements filters, overpaid will be non-critical 20,000-30,000 rubles.
So, we destroyed many stereotypes about the economy of diesel engines. Soon you will learn which coin they definitely beat their petrol female, and which of them are more profitable.
Alexander Konov, expert on choosing cars
E Avae first about what is the undoubted advantage of a diesel engine - about economy. The working process in the diesel engine differs from such in gasoline fellows primarily by the method of regulating power parameters. Since there is no need to maintain a stoichiometric mixture (constant ratio of fuel and air), then you can use high-quality regulation, simply changing the amount of fuel combustion supplied to the chamber. At the same time there is no need for throttle valve, There are no additional suction losses, and in combination with a high expansion ratio, we obtain a very high efficiency on any revolutions.
After the mass appearance of the turbocharger in eighties, diesel engines received another powerful incentive to development. Since the beginning of the century, those in the shadow of gasoline engines were due to the lower degree of revolutions and higher mass, they played them with more than, first on heavy trucks, and then on the passenger cars.
On the picture: engine Volkswagen. Golf GTD (TYP 19) "1984-85
Turbochards perfectly combined with a diesel engine's working cycle: air can be compressed as you like, no detonation restrictions, and a large expansion coefficient is also a relatively low temperature. exhaust gases, especially in intermediate modes, and therefore, the gentle mode of operation of the turbocharger.
In other words, the diesel engine is much better to carry out operation in traffic jams and with partial load. There is no overheating, from which, and the turbine works in more favorable conditions.
There are no deficiencies in this case, besides. Economicity even improves through work on smaller turns, all the same secure fuel, not inclined to light ignition. And emissions from low, because the engine always works with an excess of air.
Design features. Minuses
Cons of the diesel engine have always been closely related to its advantages. Quality regulation requires complex fuel equipment, and the greater the power and speed of rotation, the input is more expensive.
Improving the requirements for the purity of combustion increases even more its price. The large degree of compression and the expansion coefficient with a very high operating temperature in the chamber creates a large thermal load on the piston and large mechanical loads on piston group and cylinder block. Increasing the degree of forcing due to turbocharging leads to a further increase in the load on the piston group and the head of the cylinder block, nozzles and other engine elements.

As a result, the requirements for all elements of the engine are growing, like their price. Yes, and the turbines themselves are not suiced. And its fuel, theoretically cheaper than gasoline, in practice it turned out in the end is not so cheap. The high-class diesel fuel at the cost of manufacture competes with gasoline, and the price difference is more often due to taxes. In our climate to the number of shortcomings diesel fuel It also adds its tendency to paraffinization at low temperature, which requires the use of special varieties and heating fuel lines and filters in winter.
After twisting "ecological nuts", another pair of points was added to the cons of diesel engines. Highly efficient fuel combustion gives an increased number of NOX oxides, and it can be reduced by either a decrease in combustion efficiency, or ingenious chemical focus.
Both methods have their own minuses. EGR sharply reduces the engine resource, and urea neutralization requires a large number of additional technical fluidwhich also has a low freezing temperature. In addition, when combustion of liquid fuels immediately after spraying, solid particles are formed. And this soot contains many carcinogenic substances that need to somehow filter. And they turned out to be an expensive and extremely capricious component.
Why didn't Diesel say "no"?
Why on our roads during the USSR did not run diesel delimacy - and so understandable. This Vysotsky could afford to ride the car of a similar class, and those who had access to the Saloary could not even dream of such. In the perestroika, when sailors who exhauve from the GDR and other "outdoor" were afraid of the first foreign cars, the Soviet man found out the unpleasant truth. The diesel passenger car was very capricious and not particularly comfortable.
And then, then any car was already better than the absence of such, but a diesel engine, even if it was not a Volga with Perkins, but quite the "Civile" Opel or Mercedes, smelled of the diesel fuel, badly warmed up, did not always start well, vibrated and noisheled . While gasoline specimens did not differ in such behavior. The fuel equipment, naturally broken, and replaced it to the carburetor from Niva or Volga, did not work, and rare workshops with Research could pull the piece production of spare parts for TNLD.
In the photo: Mercedes-Benz 300 SD TURBO DIESEL (W116) "1977-80 Euphoria passed pretty quickly, so the machines on diesel fuel remained from those who "in debt of the service" had access to Saloary: truck drivers and tractors. The rest admired from afar, but if possible, they were acquired by "experienced people." Usually it was the option "carburetor and chain": a minimum of consumables, minimum of wear elements, is absorbed on the knee until time. Any fuel injection, and especially the injection equipment was obviously unrefidentally without a full-fledged service infrastructure.
What was next
The progress of diesel engines in the 90s was not ignored, but it was clearly lacked for a radical fracture situation. Rare diesel motors with a "passenger character" on BMW turned out legends, but the owners of the legendary and not very motors began to notice that diesel fuel in Russia does not favor the thin equipment of passenger diesel engines.
In the photo: BMW (E34) "1991-95 A couple of unsuccessful refills - and now under the replacement of the nozzle and the pump, and the aluminum GBC, especially forkarmed with their thin casting, simply melts with our high-sized diesel fuel. And by and large, cars with diesel engines hardly became more comfortable. Of course, there was no longer a "humpback" on the hood because of the special long movement of the motors, but vibration, noise, bad smell of an unheated motor and smoke on transient modes did not go anywhere.
Twenty years
The situation began to change only by the end of the nineties. Here the lawmakers have become not the Germans, but the Italian and French companies. The subsidiary of Fiat, Magneti Marelli, developed and released the first commercial system cOMMON control Rail for passenger diesel engines. And in 1997, the Italians applied the system of 1.9 JTD. Bosch bought a promising development, and already in 1998 introduced the first car with its own Common Rail system, it was with an OM611 engine.
In the photo: Mercedes-Benz C-Klasse (W202) "1993-2000 If earlier the volume of injection was specified purely mechanically for all cylinders at the same time, and the injection moment was selected using a vacuum centrifugal regulator (or electronic regulation to later versions of the pump), then in the system with Common Rail injection, it worked approximately as an ordinary gasoline motor. Only the pressure in the ramp already on the first system was 1,350 bar, and the fuel could be injected with several portions, providing preliminary heating of combustion chamber and a more complete combustion of fuel on any modes, and a decrease in mechanical loads on the piston group at the same time.
The system removed almost all restrictions on the increase in the power of diesel engines, and at the same time it allowed to avoid transitional modes. Diesel finally learned how to quickly gain momentum without clouds of smoke and power drawdown. And the insane racing of the growth of the degree of forsing began, which ended with the introduction of regular legislation, tightening the norms of exhaust and ... Dieselgit.
The popularity of diesel engines in Europe is steadily falling: according to the report of Jato Dynamics Ltd, in 2017, they fell by 8%, and the proportion of diesel engines in the sales structure of new cars amounted to 43.7%. That is, as Mark Twain spoke, "the rumors about my death are somewhat exaggerated," however, the trend has emerged completely unequivocal. Here are already "legislators of the genre" in the FCA face (who invented Common Rail Magneti Marelli remain the "daughter" of the concern) plan to turn the production of cars in a hard fuel by 2022.
Here I walked past
In Russia, we have heard the echoes of distant fighting for efficiency, ultrapure exhaust, minimum taxes and average flow Fuel on line of models. We have a diesel engine, even defeating our generic problems, and did not become massive. Large crossovers were increasingly bought with diesel engines, and SUVs and commercial vehicles were still with nineties tightly at them. The increase in the number of premium SUVs contributed to the dieselization of the fleet in the European part of Russia. Actually, there was often no alternative to diesel, it turned out to be the only acceptable option for power, consumption and taxes for a specific machine model.
In the photo: Porsche Cayenne Diesel "2010-14 Bridge cars came across diesel engines simply because in Europe they suddenly turned out to be the majority, and someone deliberately bought cars with a heavy fuel engine. But the bulk of cars was produced from us, and diesel versions If sold, it was significantly more expensive imported options.
The dyselization of the whole country did not take place, this time not because of the constructive flaws (as in the 80s and 90s), but by the will of automakers. For them, Russia remained the market, which is in demand for the gasoline motors of the past generation, and with dieselks too much trouble. In winter, they can freeze, damage the fuel equipment, and why do they need dissatisfied customers? Especially since Diesels were well sold in Europe, and the lack of production capacity always has to take into account.
In the photo: Mercedes-Benz G-Klasse "2016 The engines on heavy fuel remained or the lot of enthusiasts, which go for additional costs and risks for the sake of dreams or significant fuel economy, or those who buy a diesel engine only because, the benefit of the complexity of fuel equipment they are quite comparable.
Taking into account European trends, and a short century of current premium cars, the short-term diesel renaissance of the business class is most likely ended with the literally of the year in two or three. If only it does not support him suddenly dropped across the border the stream sold for a car in Europe. Well, the dreams of minimal expenditures for operation, rather, now belong to electric vehicles: they still have a dozen-two years in reserve to be a blue bird.
A few minutes of diesel and entertainment content
Content article:
Many drivers who use for their cars as fuel gasoline begin to discourage from buying a diesel car of their friends. They believe that the car is noise from diesel fuel and can not move into laid frost. Only in fact, any auto owner of a diesel car is not at any circumstances, it does not exchange it on a gasoline option.
Is it worth buying a diesel car Mercedes
If you compare a diesel engine with soviet carthen you can highlight the quiet engine operation, good dynamics. It is impossible to talk about the unpretentiousness of the diesel unit, because a diesel vehicle requires special attention and the use of solid food. After all, now they are sold in many places not high-quality dielary. The engine is spoiled from it.
