Diesel engine power system Toyota Corolla 5 (E80)

Diesel car Toyota Corolla has liquid cooling, single-row, four-cylinder. Located in front, across the direction of movement of the vehicle, the cylinder block is cast, made of gray cast iron. The cylinder head is cast from light alloy.

The camshaft is located at the top and drives the valves through cylindrical tappets. Valve clearances are adjusted with shims during maintenance in the presence of noise in the gas distribution mechanism. The camshaft, high pressure fuel pump (high pressure pump) and coolant pump are driven by a toothed belt.

The principle of operation of a diesel engine
In a diesel engine, clean air is sucked into the cylinder and compressed by the piston. As a result of compression, the air temperature rises above the ignition temperature of diesel fuel. When the piston is at TDC,...

Removal and installation the timing belt and adjusting the mechanism
The timing drive is usually adjusted only after repairs in which the timing belt was removed or the engine was disassembled. If it is necessary to check the timing drive adjustment, this can be done without removing the...

Air preheating device
In a cold engine, the autoignition temperature is not reached solely by compressing the air by the piston, so additional heating of the air is required. For this purpose, a glow plug is installed in each combustion...

Checking glow plugs
If you have difficulty starting the engine, you should check the functionality of the glow plugs. Test conditions: The engine must be cold (cooled to ambient temperature). The battery must be fully charged. Its voltage...

Fuel supply
The fuel supply system includes the fuel tank, hoses and pipes, high-pressure fuel pump, injectors and fuel filter. The fuel tank is located in the area of the rear suspension, the amount of fuel in the tank is shown to...

Checking and replacing the fuel shut-off magnetic valve
The fuel shut-off solenoid valve opens the fuel supply (arrow in Fig. G-2412) when the engine is turned on. It should be checked if the engine does not go down or continues to run after the engine is turned off. Turn...

Adjusting the throttle cable
Before adjusting the throttle cable, check the maximum speed and idle speed. Caution: The gas cable is very sensitive to kinks and requires careful handling. A minor kink in the cable may later lead to its breakage...

Checking and adjusting idle speed and maximum speed
Since diesel does not have an ignition system, a special tachometer is needed, which works on the basis of a photocell. It is expensive, so purchasing it is not always advisable. Warm up the engine to operating...

Removal and installation injectors
Faulty injectors are the cause of loud knocking in the engine and damage to the bearings. To find a faulty injector, let the engine idle and sequentially, one by one, loosen the union nuts of the pump fuel lines. If the...

Diesel fuel system malfunctions
Before diagnosing the fuel system, the following conditions must be met: Eliminate any errors when starting the engine. The tank must be filled with fuel, the engine must be mechanically sound, the battery must be...
