Common malfunctions and operation
- Fast flow motor oil. The reason is hidden in the west of the oil-saw rings, which is very characteristic of the engine with big mileage. It will help to build or repair with the replacement of piston rings, inserts, masonry Caps, glands and other details of the whole set.
- Oil leak. It occurs due to the wear of the pressure sensor. You need to buy and put a new one.
- Instability of oil pressure. The problem is related to the sensor itself. You need to measure pressure and replace the sensor.
- Change turns. You need to check the KHX valve, throttle valve and DPDZ. When reinstalling the last two there is the likelihood of their incorrect installation.
Even on turbocharged modifications, motors are not distinguished by a large service life of turbochargers. They need to be changed after a hundred thousand km of way. Also installed not very good drive For oil pump. In general, the engine requires good oil. On the modifications "Bims" when the timing belt breaks the valves. In general, the motors are good, but the time makes itself felt - even the most recent Fe-models are already enough old and worn.
Video by engine 1G
Power pointThe 1G FE engine has six cylinders located in a row type. Its work is carried out on gasoline fuel. The design and production of this engine was carried out by Japanese autocontracene Toyota. This event dates back to 1988. His predecessor is force aggregate 1G EU.
This power unit has high rates of reliability and dynamic qualities, with a relatively simple design. It is the most successful Toyota engine, so its installation for a large number of models, lasted for almost 30 years and ended in 2007.
First generation
For eight years, the design of it was unchanged. However, the release, in 1996 restyling new versions of cars, forced japanese company To upgrade body elements, as well as the engine, to obtain higher power parameters. According to this upgrade, the power, as well as the torque rose by 5 horse power and rpm, respectively. Constructive changes were not significant.
Motor modifications
The 1G engine has several modifications that are presented below:
- 1G-EU- Installing the first version of this motor was carried out since 1979 for the Toyota Crown car. The compression ratio in it is 8.8, the power indicator, at a speed of rotation crankshaft Equal 5400 rpm, reaches a level of 125 hp. The torque indicator is 160 nm, with a speed of 4400 revolutions per minute. In 1983, adjustments were made, thanks to which there is a reduction in power by 20, and the torque of 14 units, with the same rotation frequencies of the crankshaft. Installing this unit was carried out on the following models: Toyota Chaser. X60, CRESTA X50 / X60 / X70, Crown S110, Mark 2 X60, SOARER Z10 / Z.
- 1G-GEU. His release lasted 5 years, from 1983 to 1988. This engine, the collector of which is equipped with controls to change the geometry of the flow of exhaust gases, and in its head block equipped with cylinders, installed 24 valves. It contributed to the increase in power to 160 hp and torque up to 186 nm. In 1985, designers reduced the number of horsepower of the car to a mark of 140 units. Installation was made on data vehicles: Toyota Chaser X70, Mark 2 x60 / x70, Cresta X60 / X70, Crown S120, SOARER Z10 / Z20, Toyota Supra A.
- 1G version GTEU- The history of this type of production lasted three years, from 1996 to 1988. This motor is distinguished by the fact that the turbo element was installed. This led to a decrease in the degree of compression to 8.5. The design of the power plant has in its composition two turbocharger under the CT marking when creating a pressure of 0.5 bar, the power parameters issued by the engine are 185 hp. At the rotation frequency of the crankshaft of 6200 rpm. And the torque value reaches nm at the frequency of engine speed, equal to rpm. Motor vehicles, with installed, under the hood, Motor 1G-Gteu: Toyota Chaser X70, Mark 2 x70, Cresta X70, SOARER Z20, Toyota Supra A70.
- 1G-Gzeu / Gze was produced from 1986 to 1992. Unlike the previous engine, it was replaced with a turbine on the SC-14 compressor installation. The degree of compression was 8, therefore the piston replacement was carried out. Also, for the first time, an electronic ignition system in this power unit was obtained. At 6000 rpm, the engine has a capacity of 160 hp The torque parameters are 210 nm, when the tachometer value holds at 4000 rpm. According to the modernization of the product that was produced in 1989, they began to be marked GZE. Purchased, compressors, the pressure was 0.5 bar. When the engine turnover reaches the values \u200b\u200bof 6000 rpm and 3600 rpm, the power and torque values \u200b\u200bare 170 hp. 230 nm, respectively. Installation of compressor engines was made on the following Toyota car models: Chaser X80, Mark 2 x80, Cresta X80, Crown S130 and SOARER Z20.
- 1G-GE. The beginning of its release is dated 1988, and the completion of 1993. It was established a sensor, which determined the absolute pressure, which came to replace the air flow sensor. It has a decrease in maximum power, relative to the engine Gze, by 20 hp and maximum torque at 44 nm. These parameters are reached at the time of rotation of the crankshaft at a speed of 6200 and 5400 rpm. Cars produced with 1G-GE engine: Toyota Chaser X80, Mark 2 x80, Cresta X80, Crown S130, SOARER Z20, SUPRA A70.
- 1G-GTE is a modified version of the 1G-GTEU engine. Plant Manufacturer Modernization of the crankshaft, intercooler, nozzles, as well as inlet systems. Due to this, there was an increase in pressure to 0.75 bar. Power indicators, as well as torque amounted to 210 hp. and 275 nm at the crankshaft frequency of the crankshaft 6200 and 3800 rpm. The installation was made on cars where 1G-GE was installed, with the exception of Toyota Crown.
- Finally, the final, most successful and long-release engine, with 1G-FE marking. For the first time this motor was produced in 1988 and continued to be produced for 17 years. By constructive features It resembles 1G-GEU with a selected head of the cylinder block with a 24 valve. This unit came to replace 1G-EU. 135 hp Power and 176 nm of torque, issued this motor.

1G-Fe Beams
Major stage of modernization this engine held in 1998. In connection with the release of the Altezza model, before the designs of Toyota there was a task: to ensure an increase in power and dynamic characteristics, without changing the engine configuration.
As a result, the frequency with which the engine crankshaft rotates, has been increased, along with the degree of compression. Also, modern electronic devices, I received use in the GBC. You can distinguish this updated engine type along the Beams console at the end of the marking. Translated from English, this means the last stage of the modern motor, which he occupied in 1998.
The name of the 1G-FE power plants and 1G-Fe Beams are similar, however, they differ significantly significantly. Therefore, the interchangeability of parts of these engines is impossible.
By the end of the seventies of the twentieth century, Toyota managed to glorify the products, characteristics and the quality of which, at that time, did not exceed any competitor on the market. By that time, the issue of improving the "M" version of the MM version was abused.
So, in 79, the twentieth century from the corporation conveyor was a first engine with 1G EU marking (later Fe), which began the beginning of the new series. The design of the first engine is simple, intended for installation on cars with rear wheel drive, class "E" and "E +". Later, the basic motor was repeatedly finalized, a number of modifications were released, among which 1G Fe received a unlucky title of reliable unit in the class. New technologies and ideas used on motors, for the time were considered innovative, laid the foundation of modern engine and became an impetus for further improvement.
Toyota Altezza 1998 release year:
Description
The 1G FE engine is a power unit that has replaced Motors of the M M series and served as a prototype of the legendary series of the JZ line. Structurally, the motor diagram has an inline version, the number of surrounding chambers of six. The engine is powered by gasoline, the power supply is the volume of two liters.
1G FE engine by car Toyota Mark. 2:
The first motor was published in 79, the modification had the designation "EU" and was completed with one camshaft. This is the first Toyota engine, which was installed 12 valves. Subsequent versions had four valves per cylinder and two camshafts. Motors were staffed with a belt drive of the camshaft, it was characteristic that the belt break did not lead to the valve breakdown (exclusion, engine with vVT-I system). Later, all motors with two camshafts set a mechanism for changing the phases of gas distribution. Modification of GEU, the first engine at Toyota, which received two camshafts and four valves per cylinder.
It is noteworthy that the 1G FE engine, the technical characteristics of which combined the indicators of reliability and speakers, at the same time possessed a simple design. Power plants were used for more than ten brands of cars manufactured up to 2007.
Motor location on 1G Fe Motor:
Important! To identify the 1G FE motor, the indicators are taken from the information plate. The factory label is applied on the right side of the engine block towards the rear of the motor.
Specifications
Working out the power plant, the goal was pursued to create a lightweight and at the same time a powerful motor. Designers managed to cope with the task due to the use of a number of technologies, innovative for that time.
Thus, the head of the cylinder block and connecting rods are made of durable alloy. In the manufacture of the island, cast iron is used, the material that is better than the rest can provide the resistance of the parts to the temperature difference. Special alloy strengthening technology allows to reduce the amount of material and weight of the 1G FE engine (about 180 kilograms), while loss of strength, reliability and reduction of the service life of the aggregate. On the contrary, 500,000 kilometers without overhaul, in the order of things for this installation.
1G FE engine drive Gas distribution mechanism:
An interesting solution in the manufacture of the engine was the use of belt drive in the gases distribution mechanism. Such a feature did not have a negative impact on the reliability of the mechanism, but reduced the cost of production, reduced the dimensions and reduced the maintenance of the product. Even such a breakdown, as the belt break did not bring trouble and easily eliminated.
