The first motors of the ZZ line appeared in 1998. They were designed to replace obsolete power units of the A series. Specifically, the first representative was the ICE 1ZZ-FE. The engine resource, in comparison with the previous line, has been significantly increased. Almost all parts and assemblies began to be made from other materials, which made it possible to significantly improve the performance of the motor. Let's talk more about this powertrain.

Some general information

As noted above, the first ZZ series engines appeared back in 1998, and they were produced until 2007. But in fact, this is a Canadian development, since it was there that the first such internal combustion engine was designed. In the future, Japan was engaged in the manufacture, installation and sale. For the most part, 1ZZ-FEinstalled on cars for the domestic market. Somewhat later, cars with these power units began to be delivered to Europe and Russia.

For us, this motor remained not fully studied a few years ago. Many minders knew about its design features, but only in big cities. Now, of course, there is no such problem, because 1ZZ is widely distributed in the Russian Federation. The motor is mainly installed on top models of Toyota cars, so this engine replaced the 3S-FE rather than the A series. Well, now let's go ahead and talk about the technical characteristics.

This Japanese motor was famous for its high power characteristics and reliability. For the entire production period, the following modifications were released:

• 1ZZ-FE is the most common and massive motor in the line. Manufactured at a Japanese factory in the USA. The power of the power unit is from 120 to 140 liters. with., depending on modification.
• 1ZZ-FED is a more powerful powertrain. The key difference from the classic version is forged lightweight connecting rods. Power - 140 liters. With. Produced in a factory in Japan.
• 1ZZ-FBE is an export version that was developed exclusively for Brazil. The engine was powered by E85 biofuel.

At the same time, there are about six modifications of 1ZZ-FE. The engine resource does not differ, but the power varies from 120 to 140 hp. With. It is worth noting that the motor of this line was installed on more than 15 models of Toyota cars,on Chevrolet and Pontiac.

1ZZ-FE engine: reviews, specifications

As for consumer reviews, many motorists note that this engine is relatively trouble-free and runs for a long time. But he has, according to the drivers, one significant drawback - high oil consumption. Japanese engineers tried to fix this problem, but apparently nothing came of it, as the problem did not go away.

As for the technical characteristics, this is an in-line 4 for 16 valves with a VVTi gas distribution system. The volume of the engine is 1.8 liters, and its power is about 120-140 horsepower. The resource of the 1ZZ-FE engine is approximately 200,000 hours, which is quite a lot. Fuel consumption in the city is more than 10 liters, but on the highway this power unit has shown itself to be quite economical. It consumes about 6.2 liters, in the combined cycle - about 8 liters of fuel. The amount of engine oil is 3.8 liters. It is advisable to pour 5w30 synthetics with the necessary tolerances.

About design features

The Japanese company at the time of the manufacture of this motor made a large number of innovations in it. Here, an aluminum alloy was used as the main material for the manufacture of the block. This made the motor much lighter, but it became more vulnerable to overheating. Thin-walled cast iron sleeves. They are fused into the material of the block. It is worth noting that the cylinder block here has a number of features that need to be said. Firstly,an open cooling jacket is used. This decision made it possible to slightly increase the manufacturability in the manufacture of internal combustion engines, but at the same time, the strength of the block decreased.

The designers decided to compensate for the loss of strength in the following way. The crankcase was connected to the main bearing caps. It turned out that the parting line ran along the axis of the crankshaft, which increased the strength and rigidity of the block as a whole.

About maintenance

I would like to note that the 1ZZ-FE engine, the technical characteristics of which we examined, is not too "capricious" and forgives its owner a lot, but for the time being. There is nothing special in the maintenance of this power unit, the main thing is to comply with the scheduled deadlines. It is worth adhering to the following rules, which are prescribed by the manufacturer:

• engine oil change every 10,000 km, heavy duty 5,000 km;
• adjustment of valve clearances timing every 20 thousand km.;
• replacing the timing chain every 150-200 thousand km.

Japanese motor 1ZZ-FE is considered disposable. This means that major repairs are not possible. This is due to the fact that it will not work to re-sleeve the sleeves, since this is not provided by the manufacturer. This also applies to root bearings. Therefore, it is recommended to maintain this engine as best as possible, because if it jams, it will be difficult to repair it. Although now there are German repair kits.

Basic diseasesmotor

As for various faults, they are not found here too often. Nevertheless, this power unit cannot be called problem-free. Sometimes owners are faced with a knock in the engine and its noisy operation. This is usually a sign that the timing chain has stretched. If the mileage is about 150 thousand kilometers, then it is recommended to simply replace it. It is also worth checking the damper and tensioner, as they can also be a hassle.

Another rather typical problem for this power unit is high oil consumption. Usually the problem is solved by installing oil scraper rings in 2005 and later. Decarbonization and other similar measures are often ineffective. It is worth noting that after 2002 this problem was completely solved, so it is advisable to give preference to the power unit of these years when buying such a car.

Briefly about the main things

Many motorists are very concerned about the resource of the 1ZZ-FE engine. It is quite difficult to say after what mileage the power unit will fail. Nevertheless, there is information on the forums that the motors run about 150-200 thousand kilometers. In fact, this is not so. Firstly, the timing chain is replaced every 150-200 km. Therefore, the motor definitely lives longer. Secondly, 200,000 hours is quite a lot. It is clear that not every internal combustion engine will work so much, because a lot depends on the modes of operation and maintenance.

Quite often there are instances with a range of 300-400 thousand kilometers. Therefore, you can safelytalk about 500 thousand km. Although it will not be easy to achieve such a mileage, because the service in this case must be really good. Well, in which case you can always buy a contract 1ZZ-FE engine with low mileage.

How to extend the life of the motor?

As noted above, a lot depends on the driver. First, it's a quality lubricant. Engine oil should be bought only that recommended by the manufacturer, or an equivalent that has the appropriate approvals. Secondly, it is advisable to change the oil in a timely manner. But you should not do this every 2-4 thousand kilometers. Under normal operating conditions, the original lubricant runs about 10 thousand with a slight loss of performance. It is necessary to try to prevent oil starvation, as this can lead to a significant reduction in the resource of the internal combustion engine.

Faults in the cooling system can cause the Toyota 1ZZ-FE engine to overheat. Since the block head is made of aluminum, it can lead. It is already better to replace this motor with a contract one. It is advisable to select a gentle mode of operation. Any kind of kick-downs negatively affect the power unit, so long driving at high speeds is best avoided.

About Japanese engine tuning

All kinds of improvements to this power unit are not performed so often, due to its low maintainability. But still there are those who want to get out of 120 liters. With. - 200 or more. Usually in this case, a Japanese Toyota SC14 compressor and an intercooler for cooling are installed. Change injectors and fuel pump to more efficient ones. Fine tuning of all motor systems can give an increase in power up to 40%.

But there is another option that allows you to increase power to 300 hp. With. and more. However, such a refinement will cost much more than the engine itself. For such tuning, they purchase a Garrett GT284 kit, 550/630 cc injectors, and also change the fuel pump. Next, forged connecting rods and pistons are installed for a different compression. Also, the electronic control unit changes to Apexi Power FC. Not many people decide on such alterations, because it really costs a lot, but the result will meet all expectations. Most often, the 1ZZ-FE 1.8 liter engine is reworked in this way.

A few interesting details

We have already figured out what the resource of the 1ZZ-FE engine is. Under ideal conditions, about 500,000 kilometers can be achieved. But in practice, usually no more than 350 thousand km. It is for this simple reason that you need to be very careful when buying a used car with such an engine. After all, there is a possibility that you will come across an internal combustion engine that has practically exhausted its resource. In this case, you will not be able to perform its overhaul. The only thing left to do is to buy a contract power unit. It will cost about 60,000 rubles, plus removal and installation work. Total about 75 thousand. Whether it's worth it or not, it's up to you.

In general, the 1ZZ-FE engine, the characteristics of which we examined in this article, is highly praised by many motorists. If athe problem of oil consumption has already been solved on it, then all that remains to be done for its long and uninterrupted operation is to carry out maintenance on time. Of course, this motor also has its drawbacks, but often they are simply and quickly solved and are associated more with operation than with any design features.

Summarize

Japanese ZZ series engine definitely deserves attention. It is unfortunate that the developers did not foresee the possibility of a major overhaul, and perhaps they deliberately made the design just that in order to improve performance. One thing is for sure: this motor is not bad and is very popular. Of its design features, it is worth highlighting only vibrations. It will not be possible to completely get rid of them, you can only replace the rear engine mounting cushion, which does not always help solve the problem.

For its time, this power unit had unique performance characteristics. The 1ZZ-FE engine from Japan is always a high level of reliability. Although the development is considered partly American, it uses the DOCH gas distribution system, which was invented in the USA. But all further modifications were developed directly in Japan. In order for the motor to work for a long time and properly, it must be serviced and periodically engaged in minor repairs. It is clear that overheating must be completely eliminated, because this can lead to a major overhaul. Timely maintenance work is already halfsuccess.
