Isuzu can't add oil. What happened?

1, the reason why diesel engine can't fill the valve: In the D-type electronic control system, the throttle position sensor and intake pressure sensor are important sensors for sensing engine load. If one of them fails, the computer can use the substitute value to keep the engine working, but the working conditions are worse, and the failure varies according to the degree of damage. The throttle position transmitter is damaged, the refueling fails, and the car will fall down at a constant speed.

2. In Bosch M 154 electronic control system, the computer adjusts the steps of idle motor according to the load to keep the normal engine speed. If there are signals such as virtual wiring, out-of-control idle motor or internal abnormality during work, the computer will control the engine speed. At this time, the engine speed will be limited to a certain speed, but there is no fault code at this time, and the idle speed is generally abnormal.

3. The oil circuit is blocked and the oil supply is insufficient.

4. The pressure of the decompression guide rail of the injector is too low.

5. The pressure relief valve of * * * track is too low.

6. The diesel engine with electronically controlled fuel injection and emission is an EFI diesel engine. The EFI diesel injection system consists of three parts: sensor, ECU (computer) and actuator.
