Toyota 4A-FE engine
Japanese passenger cars produced by the auto giant Toyota are very popular in our country. They deserve it for their affordable price and high performance. The properties of any vehicle largely depend on the smooth operation of the "heart" of the car. For a number of models of the Japanese corporation, the 4A-FE engine has been an invariable attribute for many years.
Toyota 4A-FE first saw the light in 1987 and did not leave the assembly line until 1998. The first two characters in its name indicate that this is the fourth modification in the A series of engines manufactured by the company. The series began ten years earlier, when the company's engineers set out to create a new engine for Toyota Tercel, which would provide more economical fuel consumption and better technical performance. As a result, four-cylinder engines with a capacity of 85-165 hp were created. (volume 1398-1796 cm3). The engine casing was made of cast iron with aluminum heads. In addition, the DOHC gas distribution mechanism was used for the first time.
Technical specifications
Speaking specifically about the model in question, the characteristics of 4a-fe are as follows:
| View | petrol, 4 cylinders (rows) |
| Valves | 16 (DOHC) |
| Drive unit | belt |
| Overall volume | 1.587 l |
| Max power | 110 HP (5600 rpm) |
| Max torque | 145 nm (4400 rpm) |
| Min octane | 90 |
| injection system | EFI/MPFI |
| Ignition | distributor |
It is worth noting that the 4A-FE resource until the bulkhead (not overhaul), which consists in replacing valve stem seals and worn piston rings, is approximately 250-300 thousand km. Much, of course, depends on the operating conditions and the quality of maintenance of the unit.
The main goal in the development of this engine was to achieve a reduction in fuel consumption, which was achieved by adding an EFI electronic injection system to the 4A-F model. This is evidenced by the attached letter "E" in the marking of the device. The letter "F" denotes standard power engines with 4-valve cylinders.
Advantages and problems of the engine
The mechanical part of the 4A-FE motors is designed so well that it is extremely difficult to find an engine with a more correct design. Since 1988, these engines have been produced without significant modifications due to the absence of design defects. The engineers of the auto-enterprise managed to optimize the power and torque of the 4A-FE internal combustion engine in such a way that, despite the relatively small volume of cylinders, they achieved excellent performance. Together with other products of the A series, motors of this brand occupy a leading position in terms of reliability and prevalence among all similar devices manufactured by Toyota.
For Russian motorists, only engines with the LeanBurn power system installed have become problematic, which should stimulate the combustion of lean mixtures and reduce fuel consumption in traffic jams or during quiet movement. It may work on Japanese gasoline, but our lean mixture sometimes refuses to ignite, which causes failures in the engine.
Repairing 4A-FE will not be difficult. A wide range of spare parts and factory reliability give you a guarantee of operation for many years. FE engines are free from such shortcomings as cranking of the connecting rod bearings and leakage (noise) in the IW clutch. A very simple valve adjustment brings undoubted benefits. The unit can run on 92 gasoline, consuming (4.5-8 liters) / 100 km (due to the operating mode and terrain). Serial engines of this brand were installed on the following Toyota lines:
