"ZZ" (R4, chain)
The new generation of engines came to replace the old good series "A" in
1998-2000. It is impossible to say that the Japanese arranged another breakthrough on
power indicators, more attention was paid to efficiency,
"Ecologia", the prospects for modernization. And technological, which, to
regret, nevertheless took over in the fight against longevity.
Pros. Someone considers the timing chain drive more reliable, although at the very
in this case, the vitality of the motor only decreased. VVT-I system
improved the traction characteristics on the bottoms, the specific power has grown and
torque, the engine has decreased.
Minuses. There is a reason to talk more to it.
- VVT-I - In our conditions, this node is still weakly degenerate and requires exceptionally high-quality and clean oil.
The chain with the hydraulic agent also places higher requirements for
oil than the usual belt drive timing. Yes, and concessions in favor of the reduction
noise (which inevitably more from the chain) inevitably turned into
minus durability. And what will be cheaper - change in 80-100 thousand
belt with rollers or after 150-180 chain with tensioners - will show
practice.
- the compression ratio was noticeably increased (10-10.5 or more) -
therefore, the traditional Toyotovskaya gasoline omnivorous is difficult to expect
although the Japanese and worked in this direction over nutrition and ignition.
Is it possible in return to the recommended 95th in all the engines of the family quietly pour 92th - only practice will show.
The problem is regularly noted increased flow oils on a passion
caused by constructive features - wear and occurring piston
rings, wear of the sleeve.
- And finally, maintainability. Adamming
world's global traditions, Toyotov, also able to make a "disposable"
engine. Literally. Because its aluminum (more precisely,
the alloy) design does not provide for such a thing as
"Repair size" - neither original repair pistons, no borsakers.
Even if a decent resource was initially laid in this engine,
Anyway, the right to error and its correction should remain.
Especially highlighted in the 2zz-GE forced 2zz-Ge series with the system
VVTL-I (VVT plus a variable lifting height of the valve), which is on the most
it has a little common with the basic engine. He will also need to be
to say separately. Unfortunately, this is the most "gentle" and short-lived charged toyota motors.

Engines Toyota Corolla They are considered reliable and unpretentious since 1993. The Japanese are able to create structures that have a small amount possess high powerAt the same time they boast the minimum flow rate. These are technically advanced and practical aggregates with a large resource.
Engine Toyota Corolla 1.6 1ZR Fe
Motor Toyota Corolla 1.6 1ZR FE can be called the most popular and successful. This engine contains 4 cylinders, 16 valves, chain drive timing, which practically eliminates problems with it.
Engine resource is quite large.
The first 200 thousand it will be held without any interventions, the main thing is to ensure that oil consumption is not too large, on time to change the fluids (preferably after 10-15 thousand runs) and pour high-quality fuel, as the 1.6 1ZR FE engine is quite sensitive For impurities in gasoline.
How is this motor?
The engine for 1.6 1ZR FE is found in the body of the E160 and E150, it is designed to take into account the previous experience, created by advanced technologies. Gas distribution has a VVTI system, thanks to which the power takes place the most qualitatively. In addition, the electronics controls the lifting of the valves, the air flow into the system, which makes the work of the aggregate most effective.
1.6 Vvt is equipped with two camshafts, the location of the V-shaped valves. There are hydraulic components, thanks to which the valve adjustments are not required. It is necessary to monitor the quality of the oil, it is desirable to pour the original substance. If you do not do this, the hydrocompensators are out of order, you can learn about it if a knock in the engine appears.
Driving features
Device engine Toyota. Corolla 1.6 1ZR FE Maximum Reliable and Simple: Engineers removed all excess tensioners and shafts, leaving a solid metal chain. For the proper operation of the chain, only one tensioner and the calm is installed.
For convenience adjustment, the desired links are painted in orange.
Technical data
Two Toyota Corolla 1ZR FE distinguish the following features:
- Engine volume - 1.6 liters.
- 4 cylinders, power - 122 liters. from.
- Acceleration up to hundreds is carried out in 10.5 seconds.
Motor from AI 95, consumption on the highway is 5.5 liters, mixed cycle On a liter more, in the city - about 9-10 liters. The working resource is 400 thousand km. A feature is the lack of repair sizes for cylinders. In addition, the engine strongly suffers from overheating. Such engines were installed in almost all cars issued until 2008.
Motor Toyota Corolla 1.6 3zz
Toyota Corolla engines were equipped with others. In cars with the body of the E150, you can often find the engine 3zz I. Most often it is found in auto 2002, 2005 release, but the ruler was equipped with such motors from 2000 to 2007. This engine is considered an upgraded 1zz-Fe.
Main characteristics
Motor has an injection system of nutrition, so it can be denoted by the letter I.Cylinders 4, the volume is 1.6 liters, power - 190 liters. from.; City consumption is the same as the previous version, on the highway consumption will be about 6 liters, with mixed use - 7.
The hull is made of aluminum, which made the power unit easier, saved it from overheating. Basic Disadvantages:
- A frequent problem is high oil consumption. If the oil consumption is increased, the problem should be signed in the oil-chain rings. Carefully need to look at what oil filter installed. When using non-original oil consumption can increase due to poor cleaning.
- The timing chain can stretch over time, so a characteristic knock appears. Valves become less likely.
- A large problem can be a liner if you can maintain the motor irregularly. The problem of overheating though significantly decreased, but was not completely eliminated.
Resource this engine Toyota is at least 200 thousand km. Maintainability cylinders allow it to increase it.
Carefully treat the oil replacement carefully, it takes it every 10 thousand km, for which you need to purchase 4.2 liters.
Engine Toyota Corolla 1.6 VVT I
Motor VVT I is often found on vehicles issued for the Russian Federation. They have 4 cylinders, aluminum housing, 16 valves, injector power system and timing chain. Making the characteristics of the unit was better due to the use of VVT-I technology. The gas distribution phases are almost perfectly adjusted, so the motor turned out to be sufficiently dynamic with economical flow (below 10 l).
Auto 2011-2014 released hydrocompensators, which eliminates the need to adjust the valves. The serious minus VVT-I is its weak maintainability, the cylinders can almost be cleaned. The characteristics of the motor model are similar to 1ZR FE.
Conclusion
Motors on Toyota Corolla since 1993 and later releases (E80, 150, 160, etc., with volumes of 1.5, 1.6 and others) cause few complaints from the car owners. You can more fully familiarize yourself with these aggregates using video on the Internet.
Engine 3zz-Fe - enters the line of power units that are produced for toyota cars. The output of the power unit began in 2000, ended in 2007. This motor came to the change of the legendary engine 4a.
Characteristics and motors features
3zz -fe motor has high specifications. Engine 3zz is a slightly modified version of 1zz. The difference is crankshaft With a reduced piston running to 81.5 mm. Unlike 4a, the 3ZZ base did not create modifications in general, there is only one version.
Toyota Corolla with 3zz-Fe Motor
Consider the main technical characteristics of 3ZZ-FE:
Engine 3zz-Fe
Service
3ZZ -FE Motors Maintenance is no different from the standard power units of this class. That motors are carried out with an interval of 15,000 km. Recommended maintenance is necessary every 10,000 km. So consider detailed technical map Services:
The process of holding the engine 3zz-Fe
TO-1: Replacing the oil, replacement of the oil filter. It is carried out after the first 1000-1500 km of run. This stage is also called the cycle, since the motor elements are triggered.
TO-2: Second maintenance Percentage of 10,000 km run. So, the engine oil and the filter are changed again, as well as the air filter element. At this stage, pressure is also performed on the engine.
TO-3: At this stage, which is performed 20,000 km after, the standard oil replacement procedure is carried out, replacing the fuel filter, as well as the diagnostics of all motor systems.
TO-4: Fourth maintenance is perhaps the simplest one. After 300,000 km of mileage, only oil and oil filter element change.
TO-5: Fifth, for the engine, as a second breath.
Malfunctions and repair
Like any other motor, Toyota 3zz has a number of flaws that moved from his senior fellow. In principle, problems and disadvantages are the same as the ways to solve them. Consider the main malfunctions and troubleshooting:
- Knock in the motor. In this case, it is often a stretched timing chain that needs to be replaced. Valves can also knock - the absence of hydrocompensators affects.
- Vibration. To begin with, you should check the engine pillows. If it's not about them, then you should not pay attention, it is constructive features Motor.
- Elevated oil consumption. It came up to throw the rings. Also, it is worth checking oil caps.
- Floate speed. It is worth checking the RXX sensor and throttle.
Output
Engine 3zz -fe - sufficiently reliable and high-quality engines. All of them have a high rating and respect for motorists, experts. Maintenance of the power unit can be carried out independently. As for repair, it is recommended to apply to the maintenance service station.
The era of the struggle for environmental purity and efficiency led to incredible obsolescence of the legendary Toyotovsky engines of the A series. These aggregates could not be brought to the necessary criteria for environmental friendliness, to ensure the necessary reduction in emissions, lead to modern tolerances. Therefore, in 2000, the 3ZZ-FE unit was released, which was originally planned for Toyota Corolla. Also, the motor began to install on one of the AVENSIS modifications.
Despite positive in advertising, the engine was not the most successful in its segment. The Japanese applied the maximum technological and current solutions, made everything according to the methods of ecological purity, but sacrificed the resource, quality of work, as well as the practicality of the service. Starting from the ZZ series, the company Toyota no longer had a million. And Corolla 2000-2007 years of release often need Svak.
TECHNICAL SPECIFICATIONS OF MOTOR 3ZZ-FE
ATTENTION! Found a completely simple way to reduce fuel consumption! Do not believe? Auto mechanic with 15 years old also did not believe, until he tried. And now it saves 35,000 rubles per year in gasoline!
If you compare a ruler A with a series of ZZ, you can find hundreds of interesting solutions. This is a whole set of equipment for improving environmental standards, as well as to increase the cost-effectiveness of the trip. Also pleased changes in the crankshaft, which became more unloaded. In comparison with decreased piston stroke than the manufacturer achieved a decrease in the volume and facilitating the entire block.
The main characteristics of the motor are as follows:
The injection system on the 3ZZ is a traditional injector without any complications of the design. The timing is driven by chain. From the properties of the timing chain begin the main problems of this DVS.
The engine number is located on a special protrusion, you can read it from the side of the left wheel. With the removed unit, the number will not find a problematic, but on many units, it is already pretty erased.
Advantages and Positive Factors 3zz-Fe
About the advantages of this aggregate, the conversation will be short. In this generation, the Japanese designers took care of the client's wallet. Unless when determining the volume of oil in 3.7 liters - you will have 300 grams of canister on the tank. A small weight can also be attributed to the advantages of the unit.
It is worth considering the benefits of operation:
- efficiency in any travel conditions, as well as minimum emissions harmful substances in atmosphere;
- good nozzles, reliable ignition coil, do not need frequent ignition adjustment and cleaning system;
- pistons reliable and lungs, this is one of the few items piston systemwhich lives here for a long time;
- a good attachment - Japanese generators and starters live quite a long time and do not cause problems;
- work up to 100,000 km without breakdowns, if the oil and a set of filters for the unit change on time;
- the mechanical box serves as much as the engine, it does not arise with any special problems.
Also a number of parts in the GBC and fuel apparatus Have a simple design. For example, this is one of the few aggregates in which you can rinse the injector with your own hands. True, a more efficient washing on the service. Does not cause special problems and engine cooling system. But at any breakdown, it is necessary to immediately eliminate problems - overheating is fraught with very serious problems.
Problems and unpleasant moments in operation 3zz-Fe
Like 1zz, this engine has a whole complex of problems and disadvantages. You can find photo reports on the repair, on which the work volumes are visible when replacing the wheels or the bulkhead of the GBC. The overhaul is impossible to do here at all, so the resource of the unit is limited to 200,000 km, then you will have to change the engine to the contract, and rarely owners buy ZZ again.
The main problems that owners say, the following:
- Very small resource and the impossibility of repairing the block. This is a disposable motor, which is not expecting from Toyota.
- The timing chain rattles. Even before the warranty run, many began to ring under the hood, which is not eliminated even by replacing the chain tensioner.
- Vibration at idle. This is a business card of the entire series of engines, so that the replacement of the engine pillows does not solve this problem.
- Failure when attaching from the spot. Often involved in this power system, intake manifold, as well as bugs of stock firmware ECU.
- Unstable idlingFalling the revolutions for no reason. The abundance of environmental technology is real problem For diagnostics, sometimes it is very difficult to repair cars.
- Motor Troit. This occurs if the replacement of fuel filters is not completed on time, poor fuel is flooded.
- Valve stem seals. It is often necessary to change them, and along the way also eliminate a number of other problems in the GBC.
Without changing the candles on time, you will receive a number of engine flaws in work. For example, you will have to perform such a rare procedure as the replacement of the seals candlestones. Special attention It is worth paying the temperature sensor. If it breaks, you will miss the overheating moment, the motor will end.
Valve adjustment is needed manual, no compensators. Clauses of valves are usual - 0.15-0.25 for intake, 0.25-0.35 for graduation. It is worth buying a repair book, any error will cause a number of problems. By the way, after setting up and repair GBC Valve trigger occurs, you have to go carefully.
Service and regular service - what to do?
Change the oil is better every 7500 km of run, although the manual contains 10,000 km. Many owners in responses speak of a decrease in the replacement interval to 5,000 km. It is in this mode that it is more convenient to change the oil filter, fuel filters. Every 30,000 inspect the generator belts. The chain is better replaced by 100,000 km along with the tensioner. True, the price of such a procedure is very high.
Along with the replacement of the chain, the pump is often needed. On the same mileage, the thermostat change, be sure to clean the throttle, if this was not done before. If the mileage comes to 200,000 km, repair and expensive service It makes no sense. It is better to look after contract Motor Or look for a replacement for a swap in the form of another type of engine.
Tuning and Turbating 3zz-Fe - Is there any sense?
If you just bought a car with this unit, then you may notice that there is enough stock power only for the city, and even then without special advantages. So the thought of tuning may be born. Do not do this for many reasons:
- any increase in the potential of the engine in the form of power and the moment will reduce the already small resource;
- tourbin kits will disable a motor for 10-20 thousand kilometers, and there will be quite a few details;
- the process of modifying fuel and graduation system Tighten on a very large amount of money;
- the maximum percentage of increased potential - 20%, you will not even feel this increase;
- chargers sets are expensive, their installation will require an appeal to an expensive station.
You will also have to reflash the computer, work with a block head, install direct-flow exhaust. And all this for the sake of additional 15-20 horse powerwhich will kill the motor very quickly. Such tuning does not make any sense.
Conclusions - Is it worth buying 3zz-Fe?
As contractual aggregates it makes sense to look at this engine, if you want to sell a car, and old motor out of order. Otherwise, you should look after the other engine, which was also installed on the body of your car. You can check it with Toyota services or ask a question to the experienced master on a hundred.
Engine is difficult to call good. The only advantage will be economical, which is also comparative. If you turn the motor and try to squeeze the entire soul out of it, the flow rate will increase to 13-14 liters per hundred in the city. Moreover, the repair of the motor will cost quite expensive.
Owners toyota cars Fight problems great expense Oils after a run of 100-200 thousand kilometers. Many are convinced that the engines of Toyota disposable and repair are not subject to. This article discusses the myth on maintainability of Toyota engines.
Engine characteristics 1zz
The volume of the 1zz-Fe engine is 1.8 l, the diameter of the cylinder is 79 mm, the piston move is 91.5 mm.This improves traction on low revs. Motor power ranges from 120 hp. Up to 143 hp The engine is economical by fuel consumption (compact combustion chamber reduces thermal losses through its own walls). Motor weight - about 100 kg. 1ZZ-FE Low Engine Resource - Approximately 200 thousand km(That is why motorists consider this motor problem).
Engine 1zz-Fe
The Toyota 1ZZ-FE engine is put on the conveyor since 1998. These power units They stand on various auto classes C and D. The block of cylinders from aluminum alloy (used casting under pressure), the cylinders are cast iron sleeves. Therefore, the engine belongs to the category of "alloy engines". On ZZ engines are "laser-sprayed" valve saddles, which are four times thinner than usual and therefore cooled faster.
Did you know? The 1zz-Fe engine is produced in Buffalo (West Virginia).
Distinctive Motor Feature Toyota 1zz-Fe - Cooling Shirt, Outdoor (This negatively affects the rigidity of the block and the entire design). In the cylinder block there is an aluminum crankcase (covered in it planting Metal under the indigenous bearings), which binds the crankshaft supports. Carter makes the cylinder block tougher. Since the diameter and length of the neck of the crankshaft shaft are small, then the loads increase on them, and therefore wear rises.
The piston resembles a Diesel detail form (the camera is in the piston). The piston skirt is somewhat reduced: it reduces friction costs with a small work course, but the cooling of the piston drops. T-shaped pistons on the "Toyota" often knock at the smoothing (reviews of motorists about 1zz engines confirm such a fact).
Forced 2ZZ-GE
Engine volume 2zz-GE (designed for sports models of auto) - 1.8 l, cylinder diameter - 82 mm, piston stroke - 85 mm. The motor is equipped with MFI fuel injection. The gas distribution system is arranged according to the DOHC scheme. There are 4 valves on a cylinder and an additional feature engine VVT-I (This allows you to adjust the height of the valve lifting in the mechanism of changing the phases of gas distribution). The engine capacity has increased, and the volume of cylinders has not changed.
Compression ratio - 11.5: 1. Therefore, very high demands for gasoline (it can be pouring gasoline 95+). Engine force: from 164 hp until 225/240 hp (There must be a charger with internal cooling).
2zz-GE engine oil pump is his vulnerable: Any oil starvation leads to a breakdown (the pump can operate on the rings). Model 2zz is the only ZZ in series of engines, which goes with a six-speed mechanical box Transmissions or with four-speed tiptronic. On both boxes only the 4Gr-FSE engine is released.
3ZZ-FE / 4ZZ-Fe
Engine volume 3zz-Fe - 1.6 liters. Engine power 3zz-Fe - 109 hp The diameter of the cylinders is 79 mm, the stroke of the piston is 81.5 mm. The 3zz-Fe engine is a 1zz-FE motor, but with a reduced working capacity of cylinders. The diameter of the cylinder is identical to 1zz-Fe, and the piston move is shortened.
Interesting fact! The 3zz-FE engine is designed and released in Japan.
The gas distribution mechanism is the 16-valve diagram of DOHC (4 valves per cylinder) with vVT-I system. On the drive distributional shafts There is a single-row chain with tensioner and sedative. Fuel injection of this engine - electronic EFI. Sumpring degree - 10.5: 1. The feature is SMP pistons from the 1zz-Fe engine. Motor oil Requires low viscosity.
Motor volume 4zz-Fe (this is a reduced model of the engine 3zz-Fe) - 1.4 liters. The diameter of the cylinder is 79.0 mm, the piston move is 71.3 mm. Motor power - 95 hp
Attention! On these engines, the use of alcohol antifreeze and ordinary water for the cooling system is prohibited.
Malfunctions and problems 1zz
The characteristics of the engine 1zz-Fe (read above) is not bad, but it does not insure problems with the operation of the motor. Consider some of the problems that may arise with the 1zz engine, talk about faults and the possibility of eliminating them. Motor malfunction 1zz and their reasons:
Increased 1zz engine oil consumption.
If the motor is released until 2002, then you will have to change the oil-giving rings (the year of their release should be under 2005). After that, it remains to simply add the oil into the motor up to 4.2 liters. DISTRIVERING WITH EXTERFORMED OIL CONSTANT ON MOTOR 1ZZ-FE will not help.
Shup and noise in the engine 1zz-Fe. This happens if the car mileage is over 150 thousand km. The problem is hiding in the lengthening of the timing chain - it needs to be replaced. If the circuit is in order, then check the tensioner drive belt. The valve on the 1zz-Fe knocking extremely rarely, because frequent adjustment is not required.
Floating turns. In this case, rinse the block throttle valve and idling valve.
Engine 1zz-Fe vibrates. This feature of the engine design. If the vibration intensified, then inspect rear pillow Engine. The 1zz engine is afraid of overheating, therefore the loss of geometry can occur - the cylinder block will have to change.
Attention! The 1ZZ engine is not subject to repair. If the year of production of DVS after 2005, and you were exploited in a gentle mode and served on time, then he will serve for a long time.
Maintainability of the Toyota 1ZZ engine
The 1zz engine is considered to be disposable: cylindrophneum overhaul It is impossible to enjoy the block it is impossible. It is possible only to repair the crankshaft for 1zz-Fe Japanese production (the size of the crankshaft liners is a problem).
On the ZZ engines are the alloy valve seats. They are very thin and therefore improve the cooling of the valves. The diameter of the combustion chamber is small, but at the same time the diameter of the intake and exhaust ports expanded, and the diameter of the rod decreased (from 6 to 5.5 mm) - it improves air intake through the port. But such a construction is not subject to repair.
The tension chain (single-row roller with a small step of 8 mm) should be changed every 150 thousand km (otherwise it will lengthen, and there will be problems: noise in the operation of the motor, errors in the phases of gas distribution due to incomprehensible work of the crankshaft and camshaft).
The oil filter is placed in the tank (fixed on the bracket next to the pump), therefore it is harder to change it. But the fact that the oil filter is located up, perfectly solves the problem with the pressure of the oil with the engine running.
