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 craving on low revolutions. 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 are on various auto classes C and D. The cylinder block of aluminum alloy (used casting under pressure), there are cast iron sleeves in the cylinders. 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 feature toyota motors 1zz-Fe - cooling shirt, open from above (This negatively affects the rigidity of the block and the entire design). In the cylinder block there is an aluminum crankcase (planting places from metal under the indigenous bearings), which binds supports crankshaft. 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 the cylinder and the additional function of the VVT-I engine (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 DOHC (4 valves per cylinder) with the VVT-I system. On the drive of the distributional shafts there is a single-row chain with tensioner and sedative. Fuel injection 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 drive belt tensioner. Valve on 1zz-Fe knocking extremely rarely because frequent adjustment 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 issue 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 oil filter Located with a hole up, perfectly solves the problem with the pressure of the oil with the engine running.

The power unit of Japan production was recently installed on Toyota cars intended for the domestic market. The 1zz engine fell to the European, and then on the Russian car market relatively recently. In all respects, he replaced its 3s-Fe predecessor. Many motorists appreciated high quality and excellent specifications New engine 1 zz Fe. They are noted such obvious advantages as elevated power indicators (120 - 140 horse power) And the ultra-high reliability of the Japanese.

Release Modifications of the Toyota 1ZZ-Fe Engine Family

During the long period of production of these engines, samples of various modifications were developed and released:

1. 1zz-Fe.
2. 1zz-Fed.
3. 1ZZ-FBE.

The Japanese Plant manufacturer Toyota Motor Manufacturing West Virginia, located in the city of Buffalo to the USA, was engaged in the manufacture of 1zz-Fe. This motor is the most popular among the entire line, the assembly of the 1ZZ FE engine was carried out for nine years since 1998. This engine has a capacity of about 140 liters. from.

Unlike 1zz-Fe, the design of the 1zz-Fed strength unit includes smaller rods.

The engine assembly was made at the Japanese enterprise Shimoyama Plant.

The 1zz-FBE engine is designed to work on the biofuel, in accordance with the E85 standard. It was produced for cars of the Brazilian market.

List of cars on which Toyota engine is installed 1 zz:

• Toyota Corolla;
• Toyota Avensis;
• Toyota Caldina;
• Toyota Vista;
• Toyota Premio;
• Toyota Celica;
• Toyota Matrix XR;
• Toyota Allion;
• Toyota MR2;
• Toyota Opa;
• Toyota Isis;
• Toyota Wish;
• Lotus ELISE;
• Toyota Will VS;
• Chevrolet Prizm;
• PONTIC VIBE.

Engine 1ZZ Specifications

When driving around urban highways with tense car motion Gasoline consumption is more than 10 liters. In the country tracks, the Toyota 1ZZ engine is most economical - consumption of about 6.2 liters. When moving in mixed modes - 8 liters of gasoline, respectively.

Significant changes in the design of the new engine 1zz

Unlike the precursor of the engine 7a, the cylinder block is changed here.

1. It is now made from aluminum and has a smaller weight.
2. The drive of the gas distribution mechanism is equipped with a chain transmission instead of the usual timing belt.
3. Installed systems: VVTI timing, ignition DIS-4.
4. Method of manufacturing connecting rods - forging.
5. Increased piston stroke.
6. Lower weight valves are used.

The main disadvantages of Toyota 1zz-Fe engines

This motor is becoming endurance, increased reliability, the breakdown in its device is extremely rare.

During operation, the most common problems in the work of the Toyota 1ZZ family engines were seen. Some of them are marked in the following list:

• increase expense lubricant;
• the appearance of knocks and unusual noise in the 1zz operating motor;
• floating turns;
• vibration engine 1zz;
• bad stability of the working elements of the power unit against possible overheating;
• a relatively small resource of Toyota 1ZZ, equal to 200 thousand kilometers.

It is noted that the reason for the increased consumption of engine oil here is the oil-circulation rings. The folk craftsmen found the solution of this problem - replacement for new details that were made not in 2005, but a little later. To restore the engine performance, it is enough to change outdated oiling rings and add engine oil into the Toyota 1zz Carter to a volume of 4.2 liters.

Engine tapping is most often caused by excessive tension of the timing chain. As a rule, this is noticed after a distance of 150,000 kilometers. To get rid of this defect, we need to replace the timing chain on the engine 1zz. If the chain is all right, it is recommended to examine drive belt And his tensioner. The smallest probability of the engine knock is the failed valve gap adjustments on 1zz.

To eliminate such a defect in the engine internal combustionLike floating turnover, it is necessary to wash the throttle block, as well as the idle mode valve.

If the engine vibration occurs, check its back pad. If defects have not been detected, you will have to get used to this particular engine feature.

The material manufacturing material of the cylinder is often deformed due to operation at elevated temperatures. If the geometry of this node is broken, you will have to replace it with a new unit.

ATTENTION: It is officially believed that 1zz disposable enginewhich is not repaired and is not restored, the overhaul is not held here. The engines released on the basis of 1ZZ-FE after 2005 are characterized by greater reliability and durability. These are new generation motors: 2zz-GE ( sport model), 3zz-Fe, and the most perfect modification engine 4zz-Fe.

Maintenance features 1zz-Fe engine

This motor is not distinguished by high capriciousness, maintenance is carried out within a period of time specified by the Rules. The manufacturer developed the following rules:

1. To replace the engine oil through each mileage of 10 thousand kilometers.
2. If the Toyota 1ZZ engine is operated in a stressed mode, this parameter is reduced to 5,000 km traveled path.
3. The gaps of the valve distribution mechanism must be adjusted after a run of 20,000 km.
4. The timing chain needs to be replaced by a new node in 150-200,000 km.

Due to the fact that the Japanese Toyota 1ZZ-FE engine refers to a one-time type of mechanisms, its overhaul does not make sure. Such events as a sleeve is not conducted here, these actions are not provided with the design. Indigenous liners are also not subject to recovery. Extend the service life of the Toyota 1ZZ engine can only be compliance with the rules maintenance.

When jamming, the engine 1zz will be repaired quite problematic. However, the trading network car market offers sets of special remodels produced by Germany for Japanese Toyota 1ZZ engines.

How to extend the operational period of the ZZ-FE engine

After studying numerous reviews on the forums in which active motorists share their impressions, it was concluded that the 1zz-FE engine does not always look at the promised resource of 250 thousand kilometers. Not rare cases of its stop after 150 - 200,000 km.

To achieve a longer mileage of Toyota 1ZZ engines, recommended:

• operate the power unit in gentle modes;
• carry out maintenance activities within the recommended time frame;
• use lubricants appropriate quality;
• monitor the health of the cooling system elements.

When controlling the vehicle with installed engine Toyota 1zz-Fe families experienced drivers They advise you to use the gentle operation mode. Especially harmful, the so-called "kick-downs", when the gas pedal is sharply pressed, and the engine receives maximum loads, for example, when overtaking on the highway or when lifting a mountain.

The timely replacement of motor oil is another equally important factor that has a significant impact on the longcy of the operation of this power unit. Of course, under normal conditions of operation of the car, you do not need to hurry to change the lubricant every two or three thousand mileage kilometers, but 10,000 km is a sufficient mileage, in which the lubricant material of good quality retains its technical characteristics.

Important condition: Do not bring the car to oil starvation, in which the resource of the internal combustion engine is significantly reduced.

The driver depends on how correctly it will choose a brand of engine oil, depending on the following factors:

• operating conditions auto
• year of year,
• temperature regime;
• viscosity coefficient
• chemical composition
• brand lubricant and other important conditions.

If the cooling system does not provide a full heat removal from the driving elements of the internal combustion engine of Toyota 1zz-Fe, it leads to its overheating. The most vulnerable details of this engine suffering from overheating are the cylinder block and the head of the GBC block. Under influence high temperatures Aluminum alloys products are deformed, change their shape.

Japanese engine tuning capabilities 1zz-Fe

It is believed that the engines of this family are not subject to repair, so their improvements are not appropriate. However, among the car owners there are many people who wish to increase the power of their power unit, bring it to the value of up to 200 horsepower and above, instead of regular 120.

For this purpose, the following transformations are held:

1. A high-quality Toyota SC14 Japanese compressor is installed complete with a cooling intercooler.
2. The regular fuel pump and nozzles are dismantled and replaced with new nodes that have the greatest performance.

Thanks to the thin settings of the Toyota 1ZZ engine operating systems, power increases to 300 horsepower and higher. The described method has a significant disadvantage: to perform these activities, considerable material investments will be required, exceeding the cost of the new internal combustion engine.

The list of necessary components:

• a set of details included in the whale set called Garrett GT284;
• spray nozzles with 550/630 SS parameters;
• fuel pump TNVD;
• a set of pistons and forged connecting rods designed for another compression ratio;
• the native control unit changes to the new APEXI Power FC brand.

Most often as expensive alterations exposed japanese Toyota. 1zz-Fe with 1.8 liter engine.

What to do if the 1zz-Fe engine hoop caught fire

So that the driver had the opportunity to constantly monitor the condition of his car, in particular, internal combustion engine, in the cabin on dashboard Placed various sensors. Burning indicator Check Engine He indicates a violation of stability in the engine Toyota 1zz.

In Toyota, 1zz-Fe is allowed only a short-term triggering of this sensor when the engine is turned on. After starting the internal combustion engine, the bulb should go out. Otherwise, burning signal when driving vehicle Warns about faults in the power unit.

Experienced car owners recommend not to fall into panic and do not strive to immediately contact the nearest service center. There are a number of faults and reasons that can be self-diagnosed. If the signaling device starts flashing, the following studies should be performed:

1. Stop the car, but the engine does not drown.
2. Eliminate the appearance of non-standard sounds, tapping, noise, etc. in the operation of the motor.
3. Turn off the engine.
4. Check fuel system For disorders of tightness.
5. Tighten the fastenings of the gas tank cover.
6. Spend careful visual inspection The engine, did not appear if the drums and damage to the cabinet parts.
7. Measure the engine oil level in the 1zz-Fe motor using the control probe.
8. Analyze the state of lubricating fluid (no smell of gary, color change, consistency, extraneous inclusions in the form of smallest metal particles, etc.).
9. If necessary, add the missing amount of lubricating material or completely replace the oil in the engine 1zz-Fe.
10. It may be triggered by refueling with a new fuel at the gas station station, due to the inappropriate quality of the flooded gasoline. It will have to dilute the contents of the gas tank with a new portion of high-quality fluid. If the light bulb continues to burn, you need to completely change the low-quality fuel.

It happens that the engine works smoothly, stable, and at this time the light bulb indicator Check. Engine begins to flash. It is necessary to check the quality of the work of the spark plugs. It happens that one or more candles failed and do not fulfill their functions. In this case, it is necessary, without delay, replace the entire set of spark plugs. Additional signs of the fault of the candles - shock, twitching during acceleration caused by interruptions when the spark is applied.

Important: According to the regulations, the ignition candles in the engine 1zz-Fe must be changed every 25 - 30,000 mileage kilometers. Thanks timely replacement Ignition candles, the operation of the power unit is significantly improved, fuel consumption - decreases. The gaps between the electrodes of candles must correspond to 1.3 mm, not more.

Engine design

After the MZ series, the second time in its practice, Toyota produced with casting under pressure, the alloy (aluminum) block of cylinders to the 1zz Fe series. In the process of production in the block, cast-iron, thin-walled sleeves were swam.

For maximum strength of the compound and improve heat removal, the outer surface of the sleeve was made rough. As a result, the 1ZZ engine began to weigh about a hundred kilograms, easier than 30 kg of similar aggregates.

To simplify production and in order to make it possible to use molds when casting a block, an open cylinder cooling shirt was applied. If you look at the casting on top, then between the body of the cylinder block and the sleeve, throughout their perimeter, there is a gap, depth to the lower dead point of the bottom of the piston. The advantage of this design is that it is easier and cheaper in serial production. A negative point is the loss of rigidity and strength.

Also, such motors are considered to be disposable due to the impossibility of boring or germination of cylinders.Although, you can find a handicraft workshop, or the car service of ready to carry out overhaul of the engine 1zz Fe, replacing the sleeve on non-original or suitable spare parts from other manufacturers.

The tray of the alloy crankcase is also performed in a special way. The line of its fit to the block coincides with the axis of the crankshaft and the steel covers of the indigenous bearing injectographed into its housing. Due to such a design, the rigidity of the entire block of cylinders is increased, but there are problems with the selection of liners to produce 1zz overhaul.

The 1zz Fe model number is vertically, in the upper part of the block, next to the exhaust manifold, from the gearbox side. For convenience, it is best to use the mirror.

crank mechanism

Due to the increased stroke of the piston, the traction force is improved on small revolutions and reduced heat loss through the walls of the combustion chamber, which has a size less compared to the usual. But, due to the fact that the piston moves faster than the usual, there was a problem with the removal of oil from the walls, therefore, more serious requirements began to the rings on the 1zz Fe series.

For greater compactness and decrease in friction, the length and diameter of the crankshaft neck decreased, respectively, the load increased and the wear accelerated. The crankshaft is installed pulley, driven by a belt of auxiliary mechanisms.

Piston skirts are made less height to reduce the losses to friction resistance, but this has adversely affected the ability to cool. The pistons were created by T-shaped, and they began to knock on a much earlier during the smoothing of the VMT, compared with the preceding models. With rods, the pistons are connected by floating fingers, and the lids are sitting on the bolts screw themselves directly into the lower part of the rod.

GBC

1ZZ FE Series Motor The cylinder head is also made of light alloys. The shape of the combustion chamber of the conical shape is that when approaching the piston to the NTC, in the area of \u200b\u200bthe spark plug, the combustion of the combustible mixture is formed, helping it to burn more efficiently and smaller risk of detonation, thereby improving technical specifications.

Valve saddles are made with a laser spraying, unlike the pressed. They have a lesser thickness and better remove heat from the valves into the cylinder body through a plate, and not only through the rod. Due to the low thickness of the spraying and the more subtle rod of the valve, it became possible to increase the saddled diameter, therefore, increase the flow of the absorbable air and the exhaust gases produced.

As a result, due to the lack of pressed saddles, the repair of the head 1zz is impossible.

The valves became easier and for their work it became less than the effort of the spring mechanism, which, together with narrower pushers cams, also reduced losses to overcoming resistance.

The 1zz Fe series, is not regulated by the washers, they were replaced by adjusting pushers of different thicknesses, which greatly complicated the process of adjustment. The emergence of difficulties in adjustment and the increase in the cost of this procedure, the car owners began to abandon such a procedure, which also did not lead to anything good.

Lubrication system

Recommended by the manufacturer oil with SAE 5W30. Oil circulation is provided by a gear pump, with a drive directly from the crankshaft and is located on the front cover of the timing. The filter is located vertically, fastening up, at the bottom of the engine. This is the location of the filter element, helps to cope with the problem of oil starvation of the engine during start.

Cooling system

In the Motor 1zz Fe model, antifreeze pumps through the cylinder block in a circle using a water pump driven by a belt, also working on other auxiliary mechanisms. The inclusion temperature of the thermostat is located in the area of \u200b\u200b83 ° C.

GRM drive

The drive of the gas distribution mechanism began using a chain into one row, with an eight-graded pitch and adjustment using a hydraulic machine. In theory, the timing chain drive is more reliable than the belt and there is no need for a frequent replacement. But in this case, judging by the reviews of car owners and auto mechanics, the solution was not quite successful:

• The 1zz engine turned out to be too noisy, the chain rather stronger than the belt, this is the first minus.
• Appeared additional detail - Hydronetening, not very reliable on Toyota, compared with roller pulling belt.
• Also appeared rapidly wearing components - the calm and the tensioner shoe
• The cost-effectiveness of the chain drive is compared to how often it is necessary to changereten, is a controversial issue. Usually, according to the regulations, the chain is replaced by achieving two hundred thousand mileage kilometers, but if it is in good condition and is not stretched, then it is possible to extend its life. But it happens that to run 150,000 km, the tension of the chain can reach the critical level, it begins to grow and can disrupt the gas distribution phases due to offset proper position Crankshaft and camshafts relative to each other. Moreover, when replacing the chain, on the engine model 1zz Fe, it is recommended to install new components of the drive - the hydroletlayer, the sedator and the sprocket, because Details with workout can lead to accelerated wear new chain. Not subject to replacement asterisk distribution Vala.inlet control valves because it is combined with VVT-I drive, short description which is shown below.

The first engine produced was without the fastening phase adjustment function. But in about a year later, the production was first, the engine 1zz was equipped with this useful function.

VVT-I.

Toyota Corporation Development The Thase distribution system - VVT-I, smoothly rotates the camshaft with respect to the drive asterisk depending on the mode of operation of the motor. The maximum rotation is carried out at 60 °. The drive itself is a rotor with blades. Before starting, a special stopper fixes the shaft in the maximum position late ignitionTo ensure optimal launch conditions.

The electromagnetic valve, by the controller command, controls the oil flow of the mechanism entering the cavity, ensuring a delay or phase advance. The controller in turn reads information from sensors controlling the positions of the camshafts.

Intake and exhaust manifolds

If compared with previous motors, the location of the collectors has changed. In the engine model 1zz Fe, the intake manifold is located in front, and the graduation rear. Thus, it was planned to ensure quick heating of the neutralizer in cold times, the heat coming from the engine, to comply with the norms of ecology.

But, due to the cramped space under the hood, the close arrangement of the hot engine was adversely affected the neutralizer and moved it further, under the bottom of the car.

An elongated intake manifold helps to improve returns on medium and low revs. But, when it is located in front, it is almost impossible to make long. In this regard, it was removed completely cast collector, and instead, it was produced on the initial versions in the form of four aluminum air ducts welded to a single flange.

The negative property of such a design is the unreliability of welded connections. Positive - the aluminum surface of the air ducts is smoother compared to casting.

With the beginning of the two thousandths, the intake manifold was made easier. It was replaced with plastic nozzles, leaving production and reducing the heating of the suction air.

Motor malfunction and repair 1zz-Fe

A series of engines ZZ appeared in 1998 and was called upon to replace popular, but the elderly motors of the family. The first and most popular ZZ motor was 1ZZ, who came to replace, from innovations we can detect a lightweight aluminum cylinder block with cast-iron sleeves, in the timing belt was replaced with a chain, all the engines are now equipped with a system change in VVTI inputs, forged connecting connecting rods Lightweight valves, the motor itself has become long-incredible, which means the lowerhouse, here there are both its advantages and cons, but since the motors focused on the North American market, then the emphasis was made at the time.
Unlike previous and motors, the engines of the ZZ family did not receive the former mooring of modifications, but some variations, nevertheless were produced.

Modifications of the Toyota 1ZZ engine

1. 1ZZ-FE - the main and most mass engine, was produced at the Toyota Motor Manufacturing West Virginia plant. Power from 120 to 140 hp Produced from 1998 to 2007.
2. 1ZZ-FED - 1zz-Fe analogue, was going toShimoyama Plant and was distinguished by lightweight forged rods, power 140 hp
3. 1zz-FBE - 1zz-Fe engine adapted to biofuels and produced for the Brazilian market.

Malfunctions, problems 1zz and their causes

1. High oil consumption. The usual business for motors until 2002 release, the reason in the oil-circulation rings, change the rings to the released after 2005 (it was in 2005 the problem of Zhora oil was completely solved), tighten the oil into the engine up to 4.2 liters and the problems did not happen. Cutting and other movements position will not change.
2. Knock engine 1zz, noise. In most cases, the problem is to stretch the timing chain, it happens after 150 thousand km., The problem is solved by replacing. If the chain is in order, then see the drive belt tensioner. The valve on 1zz is knocking very rarely and often regulate them.
3. Floating speed. The question is solved by washing the throttle block and idling valve.
4. Vibration 1zz. Check the rear axle of the engine, if everything is in order and the motor is fully fulfilled then accept the feature of 1zz.

Among other things, 1zz is afraid of overheating and similar phenomena easily lead to a loss of geometry and replacing the cylinder block. According to official data, 1zz is not subject to repair, i.e. One-time, of course, some services offer services for a sleeve or boring service, but these are unofficial procedures, add a low engine resource, about 200 thousand km and it becomes clear why the people are not delighted with the ZZ series and consider it a problem. If your DVS is released in 2005+, it was operated calmly and maintained, then there is nothing to worry, it will drive for a long time.
Subsequently, on the basis of 1ZZ, other motors were developed: sports, 1.6 liter and 1.4 liter. In 2007, a new, more perfect engine appeared -, which replaced 1zz-Fe.

Toyota 1zz-Fe Engine Tuning

Chip tuning. Atmo

How to modify 1zz without turbines and other supervisors, options are not very much, but there is something ... Cold air intake, MONKEY WRENCH Racing Stage camshafts 2 Phase 272, lifting 10mm, exhaust direct-flow with spider 4-2-1, this junk will give Up to 30 hp, as well as a more angry and pleasant nature of the motor. It makes no sense to climb on to climb.

1zz-Fe turbine

Garrett GT28 is purchased, with a collector, midpipe, downpipe, intercooler, bloooff, along with this 2540ss nozzles, Walbro 255 pump, brains Apexi Power FC, blow 0.5 bar, we get 200 hp on stock piston. To blend more to reduce the degree of compression by installing forged connecting rods and pistons under SZh 8.5, replace the nozzles by 550ss / 630s, it will not be superfluous to make a GBC porting, cook exhaust by 2.5 inch pipe and blow 300+ hp until it falls apart.

Compressor on 1zz-Fe

Take the Toyota SC14 compressor, intercooler, fleeoff, cold air intake, 440ss nozzles, Walbro 255 LPH pump, setting up GREDDY E-Manage Ultimate, on the standard piston will give about 200 hp.

The 1ZZ engine is most common today. Literally every day our country is imported more and more cars with these force aggregates. The problem is that in Russia they are not sufficiently studied. There are very few information on them. Let's try to systematize what is.

Short story

The first engines "Toyota" 1ZZ began to produce in 1998. Paulled them until December 2007. The first unit was developed in Canada. And to produce them industrially became Cambridge, which is in the southern part of Ontario.

Almost immediately, the engine showed itself well and used mainly on cars for domestic sales. These motors put on huge quantities of the machine C- and D-class, and serially.

If we speak formally, it should have replaced the 7A-FW of the last generation. Zz engines were noticeably better in power, and also not inferior in terms of efficiency. But since these motors installed mainly on top models, they replaced 3S-Fe in fact, not too inferior to them.

Engine cylinders had a diameter of 79 mm. The piston went by 91.5 mm. The volume of the unit was 1.8 liters. The power was different - from 120 liters. from. Up to 140. The cylinder block was made from aluminum injection molding. The cylinders were cast iron in the form of a sleeve.

The 1zz-motor used a multi-point injection system. The gas distribution tract ensured the high economy of fuel at low revs. There was also an excellent traction from this unit at high speed. Among the design features, forged connecting rods can be isolated, the crankshaft, which is fully manufactured by the casting method, as well as the intake plastic collector.

In our country, these aggregates are familiar to many as toyota engines. They were published Toyota Corolla, Celica, Allex and other models. Consider their design.

Cylinders and pistons

Aluminum casting cylinder block, cast on a unique technologies at that time, became the second experience of the Japanese manufacturer to create motors from light alloys. New Toyota engines had difference. It is open in the upper part of a shirt for circulating the coolant, which is not very well reflected in the hardness of the entire structure.

Among the advantages of such a scheme, we can note weight reduction. Thus, the unit in the new modification has a weight of 100 kg, while the last model weighed 130. The main thing is the ability to produce a block of cylinders in a mold. By tradition, when the blocks were made with closed shirts, the aggregates were tougher and more reliable, but the process was more difficult, and the technology is more expensive. Sometimes the mixture could collapse.

Another feature is Carter. It combines crankshaft supports. The slot line of the crankcase and the block runs just along the crankshaft axis. Carter, made of light alloy, made in the form of a single whole with steel covers for indigenous bearings. It also increases the rigidity of the cylinder block.

ZZ engines can be attributed to long-time motors. Characteristics of the stroke and diameter of cylinders allow you to obtain improved traction characteristics. This for mass models is more an important parameterthan high power on large turns. In addition, fuel efficiency also turned out to be successful.

In project work on the engine, the developers prevailed the idea to reduce friction and make the system as compact as possible. This affected the reduced diameters of the crankshaft neck. But the loads on them have increased, and, as a result, the wear has increased.

You can highlight the piston. It has a shape that is close to diesel. To reduce friction with its large under its course, the designers reduced the piston skirt. This affected not the best on cooling. T-shaped piston on new machines begins to knock very early. Classic models have such a lack much later.

It is believed that these engines have a flaw. Many believe that the repair of the engine 1zz Fe is not possible. But this is not true. They are quite realistic to repair. Yes, there were problems with them. At first, an increased "appetite" was observed. It was caused by fast wear and lounge of the piston rings. "Treat" you can, but if the sleeve is worn out, then it serves output contract Engine 1zz.

Correction of problems in 2001

And here is not too true. After this unsuccessful year, the model of the units of the ZZ series was completed with modified rings. In the same year, the cylinder block was changed. It did not affect the previously released models, but it was possible to put the rings. However, the problem did not disappear anywhere. And today there are many cases when, because of this problem, people put a contract engine even for new cars 2005 with small runs.

GBC

Head is also from light alloys. Conical combustion chambers. Here the combustible mixture goes to the center and forms a peculiar whirl near the candle. This contributes to the rapid, and most importantly - complete burnout of going.

The 1zz-motor has a compression ratio of 10: 1. But the unit works great on the 92nd gasoline. Japanese argue that even best gasoline Will not lead to some growth of indicators. In other models, the compression ratio is more, they need gasoline better.

Instead of traditional valve saddles of steel, the saddles made of light alloys are used here. They are made by unique technologies And four times the usual, which perfectly affected cooling.

The gas distribution mechanism is an all familiar 16-valve system. Early options had fixed phases.

The Japanese reduced the weight of the valve. This made it possible to significantly reduce the impact on the valve springs. Here you can see the minimization of friction losses, as well as increased wear. Japanese engineers for some reason decided to abandon adjustment valve gaps Using the washers. Now in motors are adjusting pushers.

Radically changed the drive of the timing. Now there is a chain in increments of 8 mm. This can be called an advantage, but the chain requires frequent replacements. And it has quite significant disadvantages. The chain requires the presence of a hydraulic machine, and these are increased oil requirements. Japanese devices are not very high-quality, and the chain has a property stretching.

Intake and graduation path

The intake manifold is now ahead. The graduation is located in the opposite side. This step went due to environmental friendliness. It was necessary to make a catalyst quick-coming. However, it did not fix it for the exhaust manifold, the release was put in the back. Catalyst - under the bottom.

The intake path is quite long. He allowed much to significantly increase the return on low and medium turnover. Instead of the traditional 4-pipe collector, ZZ-engines acquired a spider with aluminum ducts.

However, Japanese engineers later came to the fact that the metal can be replaced with plastic.

Fuel system

Here, too, there were changes in comparison with the past versions. In order to reduce evaporation in fuel highways, experts did not use the scheme with a vacuum regulator. Here applied pressure regulator submersible pump. Installed new nozzles with a large number of holes. And they are mounted in the GBC.

What happened

As a result, it can be said that the engineers did enough good motor. It is powerful, economical, has good opportunities for upgrading. However, the owners are more interested in how aggregates behave after a substantial run, how to repair the engine 1zz. Alternative motor no longer exists.

Lubricant issue

According to the manual for the motor, the Japanese advise to pour exclusively 5W30. Exist special oils Toyota production. These are synthetic lubricants with a viscosity of 5W30. But specific recommendations do not exist.

Many do not know which oil in the 1zz engine is best suited. There is an original Japanese synthetic. But some prefer other options. Someone recognizes normal and 0W-20, and 10W-30, and this is not considered to be something criminal.

Opinions about the motor

Reviews in the Internet space especially and not found. Many complain on increased flow Oil. Most owners believe that the aggregate is too picky for our fuel. Repair is a simple 1zz engine replacement.

Many note that after 170,000 km, the cylinders look excellent, heads in good condition. Also write that there are no problems with them. But this is how lucky.

The problem with oil consumption was decided in 2005, and now nobody faces with it. Basically, the problem engine is a contract engine from Europe from 2002 release.

After 2005, you can freely pour into the engine oil, and it will consume it in ordinary mode.

Still owners sometimes face noise. Often, this problem is solved by replacing the chain. Valves are practically not knocking.

There is still such a moment: floating turns. This question can be solved by washing the throttle block. If you encountered vibrations, then you should check the airbags of the motor from behind. If it did not help, it remains only to accept this problem.

As the 1zz reviews are noted about the engine, it is impossible to overheat the motor. It is believed that so you can melt or deform the GBC.

According to the Japanese, these aggregates are not subject to repair. Some services can offer a sleeve or boring cylinders. But officially repairing these motors no one is engaged.

It is still worth saying that the resource of the aggregate is small. It is only 200 thousand km. But after 2005, the problem was solved. And it turned out quite economical, just for urban conditions engine 1zz. Reviews of it is confirmation.

For example, Cellica owners with this motor believe that the aggregate lacks the speakers. Consumption is about 7 l per 100 km. The engine picksily relates to a fuel. If we consider oil consumption, this indicator is at the level until 2005, therefore it is necessary to deal with such a problem. The question is solved by the wrapping of the crankcase with a sealant. But it is not for long.

Price

The fact is that these aggregates are delivered from Europe, after European drivers train are coming. Special suppliers are imported into our country.

In various companies on the 1zz engine, the price can vary significantly. On average, prices are held at about 50,000 - 60,000 rubles. But this japanese qualitywhich, despite everything, allows you to successfully move on our roads for not always high-quality fuel.

So, we found out what features 1zz-engine.
