2jz gte technical specifications fuel consumption. What cars have a jz engine and what is good about this gluttonous engine?

The 2JZ-GTE engine belongs to the legendary line of Toyota JZ engines and is the most “charged”. It's a six-cylinder inline Gas engine internal combustion volume 3 liters with DOHC gas distribution mechanism. The internal combustion engine is designed for longitudinal placement in a car, and work with rear-wheel drive or all-wheel drive transmission. JZ series engines have different volumes: 1JZ – 2.5 l, 2JZ – 3 l. The abbreviation GTE in engine markings means:

• G – timing belt type DOHC;
• T – turbocharging;
• E – electronic multi-point fuel injection.

For the Japanese domestic market, cars with this engine were supplied equipped with ST20 turbines, while export cars were equipped with ST12V turbochargers. The 2JZ-GTE was first installed in 1991 on first-generation Toyota Aristo V cars, and only after that it began to be installed en masse in the fourth-generation Toyota Supra and other iconic Japanese cars. Completed this engine A 4-speed automatic transmission A341E, and for more dynamic driving – a 6-speed manual transmission V160 and V161 developed by Toyota and Getrag. In 1997, a version of the engine with the VVTI system appeared.

JZ series engines are units with untapped potential in factory version

The engine was produced only in Japan at the Tahara Plant until 2002. Nevertheless, the durability of this engine still inspires “tuners” all over the world - they tune it, modify it on production cars, “swap” it into other cars, build “cramps” and racing equipment based on it, install it on SUVs and even boats ! Motor weight 270 kg. The guys from the RM Polishing & Gold Plating workshop were so inspired that they made an art object from this engine.

A special feature of the 2JZ is the ability to remove up to 600-700 horsepower from stock components only by increasing the boost pressure and correspondingly adjusting the electronic engine control unit. This reliability is achieved by using a cast iron cylinder block. The engine is also perfectly balanced, since the piston stroke is equal to the cylinder stroke.

Service regulations

The declared service life of this engine is 300,000 km, although in fact, with moderate driving, the mileage before overhaul can be up to 500,000 km. Let's look at the routine maintenance:

• Engine oil should be changed every 10,000 km. But during active driving, it is recommended to change the oil more often. Oil volume based on volume oil filter is 5.4 l. The manufacturer recommends using Toyota 5W-30 oil;
• According to the manual, oil consumption can reach up to 1 liter per 1000 km, but in practice a working engine consumes about 0.5-1 liter per 3000 km. The main reason for oil consumption is worn pistons, valve stem seals, occurrence of rings;
• Check drive belts It is recommended to do it every 20,000 km, and replace it after 100,000 km. It is noteworthy that if the timing belt breaks, the valves of the internal combustion engine do not bend;
• According to the manual, it is recommended to change it every 80,000 km, but practice shows that in order to preserve the service life of rubber seals, pipes and pumps, it is better to reduce this mileage to 50,000 km;
• The manual recommends replacing spark plugs after 100,000 km. This is true in practice if the engine is operating at nominal conditions and spark plugs are used High Quality;
• The air filter should be changed at least once every 40,000 km.

Also, do not forget about adjusting the valves; the gap is set using adjusting washers. This procedure is best done when checking the timing belt.

Fault overview

Like any engine, the 2JZ-GTE has weak spots, and it’s better to know about them in advance:

• Problem with timing belt tensioner;
• After washing the engine compartment, water enters the spark plug wells, and difficulties may arise in starting the engine;
• The ceramic impeller of the ST20 turbine delaminates under load;
• Common VVTI system problems. Most often the coupling and valve fail. It is very important what kind of oil to pour, in particular on engines with a VVTI system;
• Unreliability of the PCV valve (crankcase gases) also causes starting difficulties;
• Weak crankshaft pulley fastening;
• Problems with the oil pump seal. The oil pump device is quite reliable as long as its working surfaces are in proper condition, but in the absence of the required oil pressure, the cylinder head, cylinders and pistons immediately suffer;
• The system for changing the geometry of the intake manifold (Acoustic Controlled Induction System) is also not the most reliable design. This system is Toyota's own and helps increase engine power and torque throughout the engine speed range while it is running;
• Low life pump.

The most common cause of failure of the 2JZ-GTE is excessive boost, which results in valve breakage and, as a result, “Stalingrad”

Naturally, malfunctions of a different nature may occur, but this is most likely caused by the age of these engines, the quality of spare parts (if there has already been major renovation), and operating conditions.

Engine tuning options

2JZ-GTE is a favorite engine among tuners. The simplest thing you can do with your own hands is a boost, increasing the boost pressure. Stock turbines allow you to increase the pressure to 1.2-1.3 bar. But the attachments will also have to be tuned. Modernization is needed here fuel system– it is necessary to replace the injectors with more efficient ones (about 550cc), replace the fuel pump (required from 250 l/h) and adjust the ECU parameters. Thus, you can increase the power to 400 horsepower. Fuel consumption in this case already goes far beyond the limits declared by the manufacturer.

You can get the same 400 hp or more, but with a more even torque level - you will need to install a turbo kit. One large turbine is installed instead of two small ones. This scheme ensures ease of setup. Typically this is a Garrett turbine, intercooler, 1000cc injectors or two rows of injectors, a pair of Walbro pumps, and an 80mm+ throttle body. This kit can be supplemented with tuning camshafts with wider valve timing and lift, stiffer valve springs, a tuned intake manifold, an equal-length exhaust manifold and exhaust on a 3-inch pipe, and another ECU with custom firmware.

Forced 2JZ-GTE with preservation of the twin-turbo system

When tuning the engine, you need to pay attention to the ignition - if it is late, the spark will be blown away by the flow of the mixture, but you cannot ignite it too early, so that detonation does not occur. The cooling system will also require improvements - a three-row radiator is needed. With this tuning, you can increase the power to 800 hp; if more is required, you need to install forged pistons, reinforced connecting rods, and re-bolt the cylinder head. If this is also not enough and you are seriously aiming to go beyond 1000 hp, do not forget about the compression ratio, a lightweight flywheel and another type of fuel with a higher octane number.

Forged 2JZ-GTE with one huge turbine from HKS

When boosting, it is of great importance what kind of oil is poured into the engine - here it is necessary to use only the highest quality synthetic oil. Naturally, any tuning already requires serious budget expenditures.

List of car models

Despite its reliability, the 2JZ-GTE was not widely used and became a legend rather after the fact of its release. The engine was installed in the following cars:

• Toyota Aristo/Lexus GSJZS147 (Japan only) ;
• Toyota Aristo V300/Lexus GS300JZS161 (Japan only) ;
• Toyota Supra RZ/Turbo.

List of modifications

Let's look at the 2JZ engine line and their brief description:

• 2JZ-GE is the most common unit in the series. This naturally aspirated engine produces 220 hp. at 5800 rpm and 298 Nm at 4800 rpm;
• 2JZ-GTE – turbocharged version of 2JZ-GE. The version for the Japanese market produces 280 hp. at 5600 rpm and 435 Nm of torque at 4000 rpm without the VVTI system, and with it the torque has already grown to 451 Nm. European and American versions have a power of 321 hp. ;
• 2JZ-FSE - naturally aspirated engine with direct injection and increased compression ratio. Power is 217 hp and torque is 294 Nm. A different cylinder head is installed on this engine.

Engine Specifications

If you have any questions, leave them in the comments below the article. We or our visitors will be happy to answer them

Motors of the IZ series are today a legend in motorsport due to their endurance and durability. It’s not for nothing that professionals and speed enthusiasts still use motors created in the 80s and 90s. Find out what cars are equipped with the jz engine and why it is so popular.

The first copy of the 1JZ-GE series appeared in 1990. With a volume of 2.5 liters, it produced 180 horsepower and 235 Nm of torque, had a timing drive, an aluminum cylinder head and a cast iron block.

In 1995, the design was slightly improved. Compression increased, phase rotators were added, and the design of the cooling and ignition systems changed. Power began to reach 200 horses.

This is what the 1JZ-GE engine looks like

The engine, with minor modifications, was used in new civilian cars until 2007. It was valued for its great power and ease of use. It was widespread both in Japan and in America, where Toyota constantly supplied its cars.
In 1996, not only the aspirated engine was modernized, but also the supercharged engine.

The cylinder head has changed, stepless phase control has appeared, and instead of 2 small turbines, one large one has appeared. In 2000, both variants were modified by providing direct fuel injection. The engines have become more economical, but their power remains the same.

The engines have a long service life. With regular oil changes and engine maintenance, their service life is 300–350 thousand km, and full repairs are required after a mileage of 500 thousand km.

The documents indicate that the legendary “jazettes” should operate on 95-octane gasoline, but Russian drivers easily use naturally aspirated engines 92nd. The engine can easily withstand low temperatures and long mileage, but it cannot be called economical with 100% certainty.

Even at calm driving less 10 – 11 liters per hundred Notit turns out. But turbanized optionand completely “gluttonous” - he leasily absorbs from 20 liters.

The 1JZ and 2JZ designs are in demand not only due to their characteristics. They make excellent bases for tuning projects. This is possible due to the large safety margin. The motors can be accelerated to 1000 hp, leaving some of the parts from the stock motors.

1JZ and 2 JZ are similar in design, so tuning them is carried out according to the same principle. The two have more power, but the cost of the engine itself is higher, so most projects are carried out on the 1JZ engine - in terms of price-quality ratio, it turns out to be more economical.

Experienced specialists in this method of updating engines try to work mainly with the contract version of GTE.

Are there any disadvantages?

Even such common motors have their disadvantages:

1. They do not have hydraulic compensators and have valves adjusted by washers. Adjustment is required every 80 - 100 thousand km. This does not affect the power, but maintenance becomes a little more difficult.
2. Weak timing belt tension. According to factory settings, its resource is 100 thousand km, but in practice the rupture may occur earlier.
3. The pump has a short resource according to engine parameters. The water pump can run 150 - 200 thousand km. In cars with "jazettes" it is the first to fail.
4. Low reliability of the viscous coupling. Because of this, the motor can overheat at high voltage.
5. Poor cooling of the 6th cylinder. This applies primarily to 1JZ. The engineers did not calculate the heat removal lines quite correctly.

List of cars on which the engine is installed

The main “carrier” of jz is the Toyota Mark II TourerV, widespread in all Russian regions, and most of all in the Far East and Krasnodar Territory.

5 years back price auto was V within 200 – 220 thousand. rub., Today same she Maybe reach before 400 thousand. rub.

The average mileage of this model in the secondary market exceeds 200 km, so this is a budget car. Drift lovers are especially favorable towards him. They honor “Mark” in much the same way as Nissan Silvia and Toyota Supra, equipped with a 2jz engine.

Jayzets were also installed on rear-wheel drive and all-wheel drive Toyota models: Crown, Cresta, Aristo, Lexus GS300, Progress, Soarer and Lexus SC 300.

Conclusion

The jz series engines were born at a convenient time when the automotive industry had reached high level, as opposed to marketing. Therefore, they were created with conservatism, but at the same time using the latest technologies. This is how 4 cylinder valves, an electric injector, and phase rotators appeared.

The design was successful, with almost no engineering errors. It could have been developed further, but in the 2000s, preferences in the automotive industry changed. Modern cars are more environmentally friendly than cars with a jz engine, but their engines are unlikely to withstand the power of 1000 horses. People for whom this is important continue to drive Jayzettes.

The first digit in the modern coding of Toyota engines shows the serial number of the modification, i.e. the first (basic) motor is marked1JZ , A 2JZ - this is the first modification of this engine, the next modification would be called3 JZ (by “modification” we mean the production of a motor of a different size based on an existing motor).

Series enginesJZ were issued with 1990 By 2007 year, these engines belong to the “second wave” of Toyota engine building, when engines of the first wave (and earlier years, as in this case) were replaced by less reliable and durable designs with a large number of “eco-friendly” solutions, which we will talk about in more detail , especially since the seriesJZ replaced the seriesM , which I consider the most successful in the entire history of Toyota!

During the series' existenceJZ enough appeared few modifications this engine (only1JZ And2JZ WithG.E. , GTE And FSE . It is noteworthy that there has never been F.E. ) - due to the fact that this engine could only be installed along the car, it was not used in many front-wheel drive cars.
Also, unlike competitors of other brands of those years,JZ does not have hydraulic valve clearance compensators - the system is like on the VAZ-2108, only there are not 8, but 24 valves! Someone will get the job, adjusting the valves....

Availability of module throttle valve limiting access to the middle spark plugs can be explained simply - no one would bother moving the battery to the right side under the hood, and air filter to the left and remove the damper towards the intake manifold, as is done on most cars, BUT! The development program for new engines is separated at Toyota from the vehicle modernization program, so the developers were tasked with “inheriting” the engine layout 7M. By the way, such a “cunningly bent” design of the intake manifold will become a serious obstacle when installing gas equipment (gas equipment) of the 4th or 5th generation.

What were the main changes from the family? 7M ? First of all, the cylinder block was made of aluminum, trying to generally lighten the engine in various ways, for example, the connecting rods became noticeably thinner (except for the turbo variants, their connecting rods are made with a margin - thick)! The drive of all attachments was made by one belt (with a tension roller, which was produced in America), see the comparison of the drive diagram of service devices 7M- G.E. And1JZ-GE , I think it is unnecessary to say in which scheme the load on the belt and tension roller is greater:

Another misfortune happened to oil pump, he has 7M- G.E. was gear-type, lowered into the oil pan, which ensured excellent oil pressure and rapid supply after start. U JZ A trochoid-type oil pump was installed on the front cover of the engine: internalAt the top of it there are driving and driven rotors with internal gearing, which rotate in the same direction - like on an 80s VAZ V8 engine.

There are two drawbacks to this solution: firstly, all the free forces of inertia of the second order come to the pump (thank God, they are not large in an inline six), secondly, such an unnecessary detail appears as oil receiver, which slows down the oil supply after starting the engine. Moreover, on the engine under 4wd The oil pickup turned out to be longer!

I suspect that this engine will suffer during cold starts and that owners of cars that are not new will have the red “oil pressure” light on for a few seconds after starting! Also, the entire lubrication system will be critically sensitive to the originality and price of the oil filter (due to the quality check valve). The estimated service life of such a pump will be within 200 - 250 thousand km.

1996. I must say that 1JZ-GE short-stroke engine (diameter 86mm, stroke 71.5mm), i.e. There was no special marketing sense in installing VVTi on it - with long-stroke engines you can level out the torque curve, but what then? Then marketers suggested increasing the compression ratio by 0.5 atm (of course, less for turbo versions!), which together with an unnecessary system VVTi AndDIS -3, gave an increase of 14 hp. and 20 N*m!

I wouldn’t be surprised if without increasing compression, VVTi would even take a couple of horses off this engine! With systemDIS -3 the same incomprehensibility, it seems to be more modern than a distributor and has no moving parts. But in practice, it is afraid of humidity and the coils are located in a very unfavorable place in terms of temperature conditions. Manufacturers quickly abandoned such solutions, even at JZ , equipped FSE , They began to install a compact module on each spark plug - however, the buyer does not yet know what is more expensive to repair, but at least there are no high-voltage wires!

In general, my opinion, series JZ and "can't hold a candle" to the seriesM. But you also need to understand that various unnecessary catalysts, double lambda probes and a valve have appeared ERG(Rexhaust gas circulation), valve idle speed control systems, etc. .

year 2000. By the will of marketers in the family JZ appearsFSE or D-4, this is direct fuel injection under pressure, similar to diesel engine- does not provide an increase in power and torque, but it should guarantee fuel efficiency and “diesel” traction at the bottom. These engines are not recommended for sale in our country due to differences in gasoline standards here and in Japan - our gasoline is contraindicated for such engines, even when it fully complies GOST y (if you're interested, Japanese gasoline has a minimum 11 times higher lubricating properties due to additives, and the plunger pair in the pump high pressure lubricated with gasoline) thus, the owners of these engines regularly end up replacing injectors ($350 apiece) and a pump ($950) I just checked the prices on Exist...
I call this state of affairs a “subscription fee” - if you want to manage your dream, pay regularly!

2005 year. The production of engines has practically ceased, however, the remaining cars with this engine were still being sold until 2007 of the year. Nowadays, family is being replaced JZ an even more “disposable” family of the third wave has arrived - GR , which with double VVTi and has in his arsenal FSE, FXE AndFZE .

1JZ

1JZ engines were produced from 1990 to 2007 (last installed on the Toyota Mark II Wagon BLIT). The cylinder displacement is 2.5 liters (2492 cc). The cylinder diameter is 86 mm and the piston stroke is 71.5 mm. The gas distribution mechanism is driven by two toothed belts, the total number of valves is 24, i.e. 4 per cylinder.

The 1JZ-GE is not a turbocharged version of the 1JZ. Engine power is 200 hp. at 6000 rpm and 250 Nm at 4000 rpm. The compression ratio is 10:1. It was equipped with a two-stage intake manifold. Like all engines of the JZ series, the 1JZ-GE is designed for longitudinal installation in rear-wheel drive vehicles. The engine was equipped only with a 4-speed automatic transmission.

The 1JZ-GTE engine is a turbocharged version of the 1JZ. It was equipped with two CT12A turbochargers located in parallel. The physical compression ratio is 8.5:1. This modification of the engine led to an increase in power by 80 hp. relative to the naturally aspirated 1JZ-GE and amounted to 280 hp. at 6200 rpm and 363 Nm at 4800 rpm. The cylinder diameter and piston stroke correspond to the 1JZ-GE engine and are 86 mm and 71.5 mm, respectively. There is a certain probability that Yamaha took part in the development of the engine, namely the cylinder head, as evidenced by the corresponding inscriptions on some parts of the cylinder head. In 1991, the engine was installed on new model Toyota Soarer GT.
There were several generations of 1JZ-GTE engines. In the first generation, problems were observed with ceramic turbine discs, which tended to delaminate at high engine speeds and operating temperature conditions. Another feature of the early 1JZ-GTE was a malfunction of the one-way valve on the head, which led to some of the crankcase gases entering the intake manifold, which negatively affected engine power. On the exhaust manifold side, a decent amount of oil vapor enters the turbines, which in turn causes premature wear of the seals. All these shortcomings in the second generation of the engine were officially recognized by Toyota and the engine was recalled for revision, but only in Japan. The solution to the problem is simple - replace the PCV valve.
The third generation 1JZ-GTE was introduced to the market in 1996. This is still the same two and a half liter engine with a turbocharger, but with the proprietary BEAMS architecture, which consists of a redesigned cylinder head, installation of the latest VVT-i system at that time with continuously variable valve timing, a change in the cooling jacket for better cylinder cooling and new valve gaskets coated with titanium nitride for less friction on the camshaft cams. The turbo setup was changed from two CT12 turbines to one CT15B. Installation of the VVT-i system and a new cooling jacket made it possible to increase the physical compression ratio from 8.5:1 to 9:1. Despite the fact that the official engine power data has not changed, the torque increased by 20 N m to 379 N m at 2400 rpm. These improvements resulted in an increase in engine fuel efficiency by 10%.

In 2000 year Toyota introduced the least recognized member of the 1JZ-FSE family with direct fuel injection. Toyota argues the appearance of such engines due to their higher environmental friendliness and fuel efficiency without loss of power relative to the base engines of the family.
The 2.5 liter 1JZ-FSE has the same block as the regular 1JZ-GE. The block head is the same. The intake system is designed in such a way that, under certain conditions, the engine runs at a very lean mixture from 20 to 40:1. In this connection, fuel consumption is reduced by 20% (according to Japanese studies in 10/15 km/h mode).
The power of the 1JZ-FSE with D4 direct injection system is 197 hp. and 250 N m, the 1JZ-FSE was always equipped automatic transmission transmission

2JZ engines have been produced since 1997. The working volume of the cylinders of all modifications was 3 l (2997 cc). These were the most powerful engines JZ series. The cylinder diameter and piston stroke form a square engine and are 86 mm. The gas distribution mechanism is made according to the DOHC scheme with two camshafts and four valves per cylinder. Since 1997, engines have been equipped with the VVT-i system.

The 2JZ-GE engine is the most common of all 2JZs. The three-liter naturally aspirated engine develops 220 hp. at 5800-6000 rpm. Torque is 298 Nm at 4800 rpm.
The engine is equipped with sequential fuel injection. The cylinder block is made of cast iron and combined with an aluminum cylinder head. In the first versions, a conventional DOHC gas distribution mechanism with four valves per cylinder was installed on it. In the second generation, the engine acquired a VVT-i variable valve timing system and a DIS ignition system with one coil per pair of cylinders.

This is the most “charged” engine of the 2JZ series. It has six straight cylinders, two belt driven camshafts crankshaft, two turbines with intercooler. The engine block is made of cast iron, the cylinder head is aluminum and designed by TMC (Toyota Motor Corporation). The 2JZ-GTE was produced from 1991 to 2002 exclusively in Japan.
It was a response to Nissan's RB26DETT engine, which achieved success in a number of championships such as the FIA ​​and N Touring Car.
The engine was equipped with two gearboxes: automatic for comfortable driving and sports.
Automatic transmission 4-speed Toyota A341E
Manual transmission 6-speed Toyota V160 and V161 developed jointly with Getrag.
Initially, this “charged” engine was installed on the Toyota Aristo V (JZS147), and then on the Toyota Supra RZ (JZA80).
When Toyota developed the 2JZ-GTE engine, the 2JZ-GE was used as a basis. The main difference was the installation of a turbocharger with a side-mounted intercooler. The cylinder block, crankshaft and connecting rods were the same. There was a slight difference in the pistons: the 2JZ-GTE had a recess in the pistons to reduce the physical compression ratio and additional oil grooves for better cooling of the pistons. Unlike the Aristo V and Suppra RZ, other car models, such as Aristo, Altezza, Mark II, had different connecting rods installed. As noted earlier in September 1997, the engine was modified and equipped with a VVT-i variable valve timing system. This increased the power and torque of the 2JZ-GTE in all markets.
Installation twin turbocharged developed by Toyota together with Hitachi increased power relative to the base 2JZ-GE from 227 hp. up to 276 hp at 5600 rpm. In the first modifications, the torque was 435 N m. After modernization in 1997 with the VVT-i system, the torque increased to 451 N m, and engine power, according to Toyota documentation, in the North American and European markets increased to 321 hp . at 5600 rpm.
For export, Toyota produced a more powerful version of the 2JZ-GTE, this was achieved by installing the latest turbochargers using stainless steel, versus ceramic components designed for the Japanese market, as well as modified camshafts and injectors, producing a larger volume of fuel mixture per unit of time (440 ml/ min for the domestic Japanese market and 550 ml/min for export). For domestic market engines, two CT20 turbines were installed, and for the export version, CT12B. The mechanical part of the various turbines allowed the exhaust system to be interchangeable on both engine options. There are several subtypes of CT20 turbines designed for the domestic market, which are supplemented by the suffixes A, B, R, for example CT20A.

Is the 2JZ-FSE engine equipped with direct fuel injection, similar to the 1JZ-FSE only with an increased displacement and a higher compression ratio than the 1JZ-FSE? which is 11.3:1. In terms of power, it remained at the same level as its basic modification 2JZ-GE. Fuel consumption has changed for the better and emissions have improved. It is worth noting that Toyota introduces direct injection engines to the market solely for environmental friendliness and fuel efficiency, because in practice, D4 ​​does not provide any noticeable improvements in power performance. output power The 2JZ-FSE produces 217 hp and a maximum torque of 294 Nm. It is always equipped with a 4-speed automatic transmission.

2 jz engine design

The 2jz engine is distinguished by high build quality and reliable design. Design features allow the engine to be installed on various car models. The power unit has high specifications and power indicators.

Crankshaft and piston group

The motors are equipped with forged crankshaft. It has seven main and 6 connecting rod journals. The rotating parts of the crankshaft are equipped with plain bearings. They consist of two parts. The crankshaft is attached to the cylinder block by covers.

ATTENTION: The plain bearings of the 2jz gte engine have increased thickness. This allows the motor to be used under high loads.

The pistons are connected to the crankshaft using connecting rods. There is a metal pin located at the top of the connecting rod. It is necessary for the articulated connection of the connecting rod with the piston. Sliding bearings are installed at the bottom of the connecting rod.

To avoid the movement of the working mixture into the crankcase of the power plant, the pistons are equipped with compression rings. Each piston is equipped with two compression rings. To prevent lubricant from entering the working mixture, the pistons are equipped with oil scraper rings.

There are specialized openings at the bottom of the piston. They are necessary for the valves to get into them if the gas distribution mechanism belt breaks.

Gas distribution mechanism

The power plants are equipped with a two-shaft gas distribution mechanism. It includes 24 valves and two cam-type camshafts. The camshafts are driven by a belt, from a pulley mounted on the crankshaft of the power plant.

When the camshaft is rotated, the cam moves relative to the axis. The shifting cam presses on the valve stem, thereby opening it. The valve returns to its original position using a power spring.

ATTENTION: When tuning the power plant, it is necessary to replace the power springs of the valve mechanism. This will prevent the valves from sticking when using the motor under high load.

The absence of hydraulic compensators leads to the need to adjust the thermal gap. When the temperature of the internal combustion engine is low, a gap forms between the camshaft cams and the valves. When engine parts heat up, the metal expands and the gap disappears. Adjustment of the thermal gap of the gas distribution mechanism is carried out by selecting washers of the required thickness.

Powertrain lubrication

The motor has a mixed lubrication system. Components subject to high loads are lubricated with oil supplied under high pressure. Parts that are subject to light loads are lubricated by spraying lubricant supplied under pressure.

Oil pressure is pumped into the system by a gear-type pump.

To avoid excess pressure, a pressure relief valve is built into the system; it discharges part of the lubricant into the crankcase pan when the pressure is exceeded.

The lubricant not only improves the sliding of rotating parts, but also removes various types of contaminants from the rotating parts. Cleaning the lubricant from contaminants is carried out in two ways:

1. A mesh installed on the oil receiver. The metal mesh prevents chips or large contaminants from getting into the oil;
2. Paper filter element. A removable filter element cleans the lubricant from small metal shavings or fine contaminants. For normal operation The power plant needs to regularly change the filter element.

Power plant cooling

Power plants 2 jz have a forced-type liquid cooling system. The movement of the coolant is carried out using a centrifugal pump. The pump is belt driven from a pulley mounted on the engine crankshaft.

Cooling working fluid carried out in the radiator. Coolant from the cooling jacket enters the upper radiator tank. The liquid flows through thin channels into the lower tank, from where it moves into the cooling jacket.

REFERENCE: Liquid cooling occurs when an air mass passes through the radiator honeycombs. The forced movement of air mass through the honeycombs is carried out by a fan. This design allows the power plant to be used regardless of ambient temperature.

The engine cooling system is equipped with an expansion tank. It is necessary to prevent pressure from building up in the cooling system. To avoid damage to the cast iron cylinder block when high pressure occurs in the cooling system, the manufacturer installed specialized plugs.

Engine tuning 2 JZ

In order to improve technical characteristics, car owners perform tuning of the 2 jz engine. Thus, it is possible to improve the performance of the 2jz engine. When performing tuning, it should be taken into account that modernizing the power plant leads to a reduction in engine life.

To improve technical characteristics, perform the following steps:

• Increase the charge air pressure. To do this, install an intercooler with increased performance and cool the air mass inlet;
• Install fuel pump high performance. Use a pump with a capacity of 280 l/h;
• Flashing the electronic control unit. To do this, install an adjustable ECU. It is important to consider that firmware of the electronic control unit can only be performed by qualified specialists. Violation of this rule may lead to incorrect operation of the power plant or complete failure of the electronic control unit;
• Forged pistons and crank mechanism parts are installed. This is necessary for normal operation of the power unit under high loads;
• Replace turbines with products with higher productivity, or one efficient compressor;
• Strengthen the springs of the gas distribution mechanism. Camshafts are changed.

From the above it follows that the 2jz engine is a high quality power plant. The motor has high technical characteristics and balanced operation. Thanks to your design features The power unit is in demand when performing tuning.
