In the model range of cars Renault Logan there are versions available to buyers with different options interior equipment, engines and gearboxes. This allows you to choose the most optimal car in terms of configuration for a specific future owner, taking into account his wishes and ambitions.

The top-end option among Renault Logan modifications is the version with a 1.6-liter 16-valve engine, 1.6 technical specifications are excellent. Next, the capabilities and technical characteristics of the 1.6 engine and the car as a whole in such equipment will be considered.

Weight and overall parameters

Despite the fact that the car is positioned as a reliable and unpretentious family "assistant", it still requires timely and high-quality routine maintenance. Maintenance, the fulfillment of the conditions of which will allow the owner to enjoy the trouble-free daily operation of his “friend” for many years, has an engine of 8 or 16 valves.

Although the Renault Logan model is compact and not designed to carry large loads, the developers managed to give it a fairly roomy luggage compartment and very comfortable lounge which can comfortably accommodate five passengers.

Among the main overall characteristics the length of the car is present, because the capacity of the trunk and the spaciousness in the cabin depend on it. According to official technical data, this dimension is 4346 mm. Not less than important parameter, which has a positive effect on the supply of free space in the cabin, is the width of the model, which for Renault Logan is characterized by a mark of 1732 mm (at the edges of the mirrors). The height of the model is 1517 mm. Such an important parameter for operation in the conditions of domestic roads as ground clearance has a very impressive value - 155 mm. This allows the car to cope with light off-road and suburban ruts.

The mass of the Renault Logan model, according to the manufacturer, excluding passengers and in the absence of cargo in the trunk, is 1127 kg. With the maximum possible (regulated) load, this parameter reaches 1545 kg. Recall that the volume luggage compartment very solid and boasts 510 liters of free space, but the car has such technical characteristics 1.6.

Motors and dynamic capabilities

For the Renault Logan model on the market, the 16-valve 1.6-liter version is not the only option in terms of equipment. The entire engine range of these cars has similar data and is able to please the owner with efficiency due to the small working volumes of the combustion chambers.

All three engine versions are characterized by their transverse arrangement under the hood. They are atmospheric units with 4 cylinders. All engines are not turbocharged. The main design difference is a different number of valves in the block head - an engine with 8 or 16 valves.

What are the specifications of the 1.6 version? All units are equipped with distributed fuel injection, which contributes to the increase of dynamic capabilities. The regulated type of fuel for them is AI-92 gasoline. Also, as an alternative, the manufacturer provided for the possibility of running engines on AI-95 gasoline.

Specifications 1.6 engine with a 16-valve gas distribution mechanism, a power of 102 liters is available. with., which is achieved at revolutions crankshaft 5750 rpm The maximum torque for this version of the motor is available at 3750 rpm and is 145 Nm.

With such traction characteristics, the car is able to accelerate to the first hundred in 10.5 seconds. The value of the maximum speed is an impressive 180 km / h.

Such an operational parameter as fuel consumption is positioned apart. According to official technical data, the 16-valve version of Renault Logan is capable of consuming no more than 9.4 liters per 100 kilometers in the urban cycle, even taking into account dynamic driving. For mixed cycle the value of fuel consumption is reduced to a mark of 7.1 liters, and for suburban traffic it is 5.8 liters at all.

Summing up

Based on the above aspects, once again you can be convinced that, thanks to its balanced technical and consumer characteristics, the Renault Logan model is one of the most reliable, unpretentious, economical and practical cars available in the domestic market.

Such features allowed the sedan to achieve enviable popularity with a large army of car fans and continue to gain a reputation that is strengthening from year to year.

Advantages:1. A very roomy interior - for a family mom + dad + 2 children + mother-in-law - it fits perfectly. The back seat fits 2 child seats and another mother-in-law (165cm, 75kg). The trunk includes 2 children's bikes with side wheels !!!, or a gas lawn mower, or a bunch of things, the arches of the trunk lid are a little in the way, but you can get used to it. But the lid opens very wide. 2. The cabin is quite quiet when driving. Additional soundproofing (Prestige version) was not required, although I read the reviews about the noise level before buying the car and planned to do it. The budget for additional soundproofing is 17,000 - 25,000 rubles. in the Renault Avtomir showroom. "Lucky Motors" said that they would not deal with such nonsense at all .... 3. Excellent energy-intensive suspension and good geometry: ground clearance under load 155 mm and wheelbase 2630 mm. I comfortably pass speed bumps, pits and potholes. I drove along a broken country road with a rut, puddles 30 cm deep, gullies and slopes of 25% (to Chertovo Gorodishche from the village of Iset) with four passengers - I drove easily. He asked the passengers to leave only a couple of times. On the way to the dacha - 2 km of country road - I fly like on asphalt. It's a pity to see the owners of Mazda 3, Ford Focus and other low million cars when they try to follow me over potholes, poor things. One day from me TOYOTA Highlander latest generation along a broken country road (the road for trucks from 44 km of the EKAD to Ganina Yama) lagged behind - it's a pity expensive car. And when later on the pavement Toyota caught up with me and began to go around on the left - the driver almost leaned out the right window to see who was driving in “this Logan” .... ... and then, when I drove around, I pressed down on the gas with irritation and a twinkle .... ….I was crying. 4. Gasoline consumption is no more than that of classmates, although I want less: In summer, city / highway - 8.9l / 6.7l per 100 km. In winter, city / highway 11l / 7.8l per 100 km. In the city, I like to accelerate sharply, but on the highway I drive 90 - 110, overtake trucks, turn the engine up to 4000 rpm. I have been using ER friction winner in the motor from the very first kilometers - I like it; the engine turns easier and gasoline consumption is reduced by 0.5 - 1 l per 100 km on the highway. 5. Excellent visibility from the front seats and for children from child seats on rear seats. 6. good review in the rear-view mirrors (on the Prestige version there are large mirrors). 7. Live engine, although I already want more moment. I had a run-in up to 28,000 km, after that the car went faster. The torque is especially felt when I'm driving alone. If the load is full, it is difficult to overtake on the track, only if with a large margin. I fill in 98 gasoline in the summer. The motor accelerates the car faster than on the 95th and 92nd. In winter, if it is colder than -25 degrees - 92, so that it starts better in frost. The motor starts with a half turn of -32 degrees, no self-winding and WEBASTO. It costs a big battery. I also use a special blanket (Avtoteplo) in winter. The motor with it cools down more slowly. 8. Comfortable fit, especially in the rear seats - like at home on the couch (compared to the Skoda Octavia and Volkswagen Golf 6 - you sit there like in a basin). 9. Comfortable rear doors. Back it is convenient to seat children and download, for example, a TV. 10. Good head light: dipped headlights - the headlight angle is adjustable and the far one hits at 150-200 m. It is very convenient to move 90 - 110 km / h along the night highway. 11. Managed like small car(compared to the Skoda Octavia - this is a real ship). I love it. 12. Does not blow off a narrow highway (2 traffic lanes without a dividing line) with an oncoming air flow from a truck when driving at 110 km per hour, and the truck towards 90 km / h (compared to the VW Polo - this one was constantly blown away, I had to keep it)

Flaws:1. They don’t respect you on the road if you hesitate a little, but when you drive fast and show all the lane changes, it’s normal. 2. Very expensive official dealer service. Maintenance after 15,000 km according to the regulations (diagnostics + ELF oil 5W-40 in the engine, spark plugs), I do it more often - every spring and autumn. 1, 2 and 3 MOT - 8,000 rubles each. I change the cabin filter myself, it costs up to 450 rubles, I try to change it every 2 months. In the summer I put coal. 4 MOT for 60,000 km with the replacement of the timing belt in the Lucky Motors salon was promised to be done for 17,000 rubles. 3. Snow and dirt accumulate behind the seal along the upper edge of the doors. The snow freezes and turns into ice, you have to sweep it out so that it does not pour into the cabin when you open the doors. 4. In wet (frosty) weather, the rear windows fog up (freeze). 5. No lumbar support in the driver's seat. Only 2 position of the driver's seat in height. On long trips (350 km), the back gets tired. 6. There are no regular hooks for fixing the grid in the trunk. 7. Insufficient rear view when parking - it is better to order a parking sensor (about 8,000 rubles), or to park in narrow places only in front. I hit the bumper twice (without consequences), but only in the first days of operation. Then you get used to it, and the dimensions are read very well. 8. It seemed to me that the interior cools down very quickly when you turn off the engine in winter, but this is subjective. 9. Aerodynamics - after 80 km / h, the oncoming air flow begins to whistle. You have to get used to it. Drag coefficient of 0.36 (like a brick …))))) 10. The coating was washed off with patches of making "chrome-like" and a black coating on the doors.

Description:My auto history. Beginning in 2002: 1) VAZ 2105 1.5 4-speed manual transmission (own) - 40,000 km 2) Renault Symbol 1.4 5-speed manual (service) - 12,000 km 3) VW Polo 1.4 8cl. 5-speed manual hatchback (service) - 105,000 km. 4) Skoda Octavia 1.6 16 cells 5-speed manual (service) - 23,000 km 5) Renault Symbol 1.4 16 cells. 5-speed manual transmission (service) - 26,000 km. 6) Renault Logan 1.6 16 cells. 5-speed manual (own) - 44,500 km today. I bought Logan in February 2011 at Lucky Motors in Yekaterinburg: 77,000 rubles down payment + about 15,000 rubles per month. for 3 years (Offer price 498,000 rubles). Additionally, I bought rubber floor mats in the cabin (1500r), a plastic tray in the trunk (1000r), installed a cabin filter (2000r). Insurance for 1 year: CASCO (32,000 rubles) + OSAGO (4,000 rubles) in Renaissance Insurance. Winter tires Continental ContiIceContact 185/65 R15 are studded (it seems to work quieter than Nokian Hakkapelitta 4, but gasoline consumption immediately after tire fitting increases by 1.5 - 2 liters per 100 km). I change to native 15`` discs and balance twice a year, I pump it with nitrogen - so, in my opinion, pumping is less often required. (Tire fitting costs about twice a year for 1200 rubles) Now there are 44,500 km on the odometer. Mode of operation: 1. in Yekaterinburg, Chelyabinsk, Kurgan. 2. to the cottage 25 km of asphalt and 3 km of broken primer with pits, swollen asphalt and puddles. 3. along the highway Yekaterinburg - Chelyabinsk and Yekaterinburg - Kurgan. The machine is very satisfied. Lots of reliable comfortable car for Russian roads without ponies. chose New car for 400 000 rubles Watched: 1. Renault Logan 2. Hyundai Accent. 3. Lada Priora. 4. Skoda Fabia. 5. Nissan Almera Classic There was also a desire to take the Skoda Octavia 1.8 TSI 7-DSG for 900,000 rubles. and get into the very ... in debt, but sober calculation won. I chose Renault Logan (collected reviews during the year) for: 1. Reliability (according to taxi drivers in Yekat, Kurgan and Tyumen, cars go 200,000 km without repair. They start up in any frost.) 2. Spaciousness (when I was without a car - myself I traveled as a passenger in Logan - I liked the visibility and convenience of the rear sofa. It is also important for me - the children from the seats have a very good view.) 3. High ground clearance of 155 mm is important for me to drive to the dacha on a broken primer in principle ...) 4. Build quality (mechanics in the service said that Lada was welded and assembled poorly and did not advise taking it, but Logan was excellent. Prestige package because: 1. This is the maximum speed and it has everything 2. The most modern 1.6l 16-valve engine in the line, 102 hp 134 N/m, 3. The best soundproofing in the line, 4. The best interior trim in the line, 5. The most elegant appearance 6. Maximum safety (watched all euroncap crash test videos) t white - because: 1. It basks less in the sun in summer, 2. White is the brightest car at dusk - this is safety. 3. Any small car looks bigger and smarter in white. My next car, if income and family composition do not change, will be RENAULT Duster 1.5L dCi 6-speed manual 4*4. I want to try diesel four-wheel drive and more ground clearance.

Faults and engine repair Renault Logan / Sandero 1.6 K7M

Engine Renault Logan K7M 710 1.6 l. 86 HP nothing more than a regular K7J 1.4 liter, only with an increased piston stroke (from 70 to 80.5 mm), of course, the height of the block slightly increased, the clutch had a larger diameter, the flywheel increased and the shape of the gearbox housing changed. Structurally, the Logan 1.6 liter engine, like its low-volume counterpart, has the same archaic design of the middle of the last century with rocker arms and a strange oil pump drive system from lower-mounted Renault engines of the 60s. In spite of everything, with a careful attitude to the engine, service and maintenance, oil changes 2 times more often than according to the instructions, it is very, very reliable, according to in-plant data, the Logan 1.6 engine life is about 400 thousand km, in practice the engine drove a little more .
In 2010, the K7M 710 was replaced with the K7M 800, the motor was strangled, pulled up to the Euro-4 environmental standard, the power decreased to 83 hp, there were no design changes.
The disadvantages of the K7M are the same as those of the K7J 1.4 engine, high flow fuel, often Idling the speed starts to float, constantly (once every 20-30 thousand km) it is necessary to adjust the valves, there were no hydraulic lifters, the timing belt drive, when the belt breaks at Logan 1.6, the valve bends, so we change the belt every 60 thousand km. All the same leaks of the crankshaft oil seal. The motor is noisy and vibrates. According to the design of the Renault Logan 1.6 engine and where the engine number is located, the information is set out in the article "motor K7J“, which, apart from the volume and related changes, has no other changes. It also describes all the faults and their causes. Speaking about which Renault Logan engine is better than 1.4 or 1.6 8 valve, take 1.6 ... the engine is the same, but the low-volume engine is very weak.
An engine was also created on the basis of the K7M K4M with a 16 valve cylinder head and other significant innovations, the power of such a motor is much higher and if you choose (for example, Logan, Sandero), always take it, you will not regret it.

Engine tuning Renault Logan K7M 1.6

Chip tuning engine Renault Logan

Logan K7M 800 engine, you can remove the catalyst, restore its original power of 86 hp, put the exhaust and flash the sport firmware, maybe add a couple more horses, but nothing will change significantly, except for fuel consumption, now your engine will eat more))

Compressor and turbine for Logan 1.6

The installation of a turbocharger and a compressor is described using the example of a 1.4 liter engine, and all this is 1 in 1 applicable to 1.6 liters. Engine power Logan 1.6 will be an average of 5-10 hp. more with the same approach. Looking ahead ... you will not be able to achieve great power.

Engines of the Renault Logan model, endowed with a cylinder capacity of 1.6 liters and characterized by two power options: 82 and 102 liters. pp., are most common in the vast domestic car market among the entire list of modifications of this model. These motors have proven to be reliable and maintainable. The resource of the engine is very large. They can please the owner with such relevant advantages that meet the requirements of advanced engine building, such as:

• reliability of elements in the cooling system;
• increased engine resource;
• compliance of the maximum power indicator with modern trends in the automotive industry.

This is evidenced by numerous reviews of the owners.

About the history of development and design features of the units

The 1.6 and 16-valve engine has differences from the newest modifications, they are the lack of a valve timing control mechanism, such an engine device significantly reduced the dynamic capabilities of the car. But among the advantages remained excellent maintainability and durability, that is, increased engine life, thanks to simple design solutions from the manufacturer.

A 1.4-liter 8-valve engine is incorporated into the engine device, which confirms the identity of the layout and the similarity of the design aspects of both engines.

The changes affected the following components and systems:

• the volume of cylinders has increased (engine 1.6 liters), which made it possible to increase power in tandem with torque and improve the dynamic characteristics of the model;
• the output of the unit increased by 11% (up to 82 “horses” for the 8-valve version), such an engine arrangement led to an increase in torque to a mark of 132 Nm;
• the cooling system has undergone an adjustment (the need for this refinement is caused by an increase in engine power);
• the cooling circuit has not received any fundamental design changes, and its elements have been modified in order to achieve greater performance, for which some new components have been integrated, which led to an increase in the resource and efficiency of the system, especially in critical operating modes;
• power increase up to 102 hp With. achieved through the use of new components in the piston-cylinder group and the valve mechanism:
• the number of valves doubled (from 8 to 16), which ensured better filling of the combustion chambers with a mixture and led to an increase in power and dynamic capabilities;
• the motor resource has significantly increased due to the use of parts from new, more durable alloys;
• after applying the previously indicated design solutions in updated engines, Renault Logan developers managed to achieve significant fuel efficiency:
• 1.5 liters at a distance of 100 km on a 1.6 engine with 16 valves;
• 1.0 liter in the case of 8-valve engine versions.

All these innovations made it possible to substantially make the 1.6 liter engine. more modern (especially the 16-valve version), the engine life has become higher. Although the developers did not apply progressive and innovative design solutions, this engine upgrade for Renault Logan still made it possible to attract a large army of new potential customers to the updated model.

In addition to constructive innovations, these units began to comply with the requirements of Euro-5 environmental standards. In the future, the manufacturer Renault models Logan planned to bring the engine design to the level of compliance with Euro 6/7 standards.

Updating the 1.6-liter unit was not limited to the use of a 16-valve head mechanism. Achieving an increase in traction and power characteristics was carried out thanks to significant transformations, including:

• increased intake and exhaust systems, which was a necessary measure to bring the motors to the advanced level of the environmental standard;
• the use of new elements in the cooling circuit, which made it possible to significantly improve the efficiency of its functioning;
• replacement of the generator with an increased performance option for the Renault Logan model, which made it possible to cope with the increased loads on this node (now the power varies depending on the configuration of the model)

On the durability and maintainability of motors

The experience of operating 1.6-liter engines did not reveal significant shortcomings in both modifications of 8 or 16 valves (16-valve with a power of 102 hp and 8-valve with 82 “power”). According to the manufacturer, the resource of these units is approximately 200 thousand km, and what value this parameter will actually have depends on the owner of Renault Logan. Accordingly, the reviews of car owners about this are positive.

If all maintenance work performed in a timely manner and in accordance with the manufacturer's recommendations, then the engine life can reach 400 thousand km, which is confirmed by numerous real examples. The only unpleasant surprise may be a broken timing belt, as evidenced by the reviews. In the event of such an accident, the pistons collide with the valves, causing them to bend or completely break.

Summing up

The considered power units of 8 or 16 valves are traditionally for the French manufacturer of all models, including Renault Logan, they are unpretentious in operation and wear resistant. In terms of dynamic performance, these motors are not "sporty", but they will not allow the owner to keep up with heavy traffic on the road. Thanks to their balanced characteristics, 8 or 16 valve engines deservedly gained the trust of many fans. Renault cars logan. Their feedback is very, very positive. There were cases when motors failed at runs of 100 thousand km due to defects in the crankshaft liners, but these precedents were not characterized by mass character.

Inexpensive Renault Logan cars began their history back in 1998, when the French manufacturer decided to start producing cars targeted at developing countries. But, it was in Russia that these cars gained really impressive popularity. The fact is that by 2014 the production of cars under the auspices of Renault on Volzhsky car factory reached 160 thousand units per year.

Renault Logan engines

K7J engine for Renault Logan 2006. One of the most massively installed engines on this model

If you look closely, in the K7J you can see some of the features characteristic of the ExJ series, produced by Renault in the eighties of the last century. Such "archaisms" include the chain drive of the oil pump, the old types of timing rocker arms, as well as the way some parts are placed. Other solutions for a 1.4-liter engine are practically the same as other single-shaft engines from the SOHC family.

This is all the same in-line arrangement of cylinders in a vertical layout, the presence of two valves per cylinder, as well as a combined lubrication supply system. However, all this does not reduce the advantages of the motor,. At the same time, Renault Logan with this power unit can accelerate to "hundreds" in thirteen seconds, keeping the maximum speed at around 162 kilometers per hour.

K7M engine

Less popular 8's valve engine 1.6 liter - K7M

The K7M version with an increased volume differs little from its “younger brother”, only in the piston stroke, which has become 10.5 millimeters larger. In addition, a different type of clutch and a flywheel with an increased diameter are used. This made it possible to increase the dynamic and speed indicators by almost 10 percent. But the disease with the fragility of the clutch cable could not be avoided, therefore.

K4M engine

The most powerful 16 valve engine in the range. Such an engine was installed on the LUX version of the car.

But the K4M engine with a volume of 1.6 liters and a power of 102 horsepower boasts the presence of 16 valves.

It includes a pair of lightweight camshafts as well as a brand new piston system. It is not necessary to adjust the valves too much, since hydraulic compensators are present in the design. At the same time, "hundred" is typed in 10.5 seconds, and maximum speed will be 180 kilometers per hour.

Advantages and disadvantages of 8-valve engines

The advantages of eight-valve engines include their low cost, simplicity of design and good reliability. In addition, it will be easy to repair motors, and the torque will be quite high.

As for the disadvantages of such motors, they are, poor quality work at idle, as well as the need to adjust the valves every 20 thousand kilometers. And, when the timing belt breaks,. And we are not talking about increased noise.

Advantages and disadvantages of 16-valve engines

But the 16-valve engine offers an increased resource, compliance with the Euro-4 standard, as well as low level noise. In addition, the cooling system will be more reliable and modern than the 8-valve unit. Keep in mind that spare parts for such a motor will be more expensive, the problem of valve “bending” will remain, and the “elasticity” index of the motor will be minimal, which will affect the quality of the ride when overtaking.

Video acceleration to 100 km per hour on a 16 valve

conclusions

It is difficult to say which motor is better. For lovers of new features, the sixteen-valve version should be recommended, while for those who prefer the simplicity of the motor, its eight-valve version is better suited.

A 16-valve engine is more expensive to maintain, as it has a different attachments(, generator, etc.)

But one thing's for sure, to ensure maximum resource operation of the engine, it is necessary to observe the temperature conditions of the engine.

Symptoms that indicate engine malfunction:
