What is the reason for the high speed of the car?

The reason for the high speed of Pacific Auto Network is 1. The air intake system is out of order, and the throttle opening suddenly becomes larger. 2, the cylinder pressure is not enough, check the piston ring and piston wear. 3, the problem of oil. 4. The air-conditioning clutch slips or is damaged, and the engine is suddenly unloaded, resulting in an increase in speed. 5. Transmission computer forced downshift or internal fault of transmission. 6, the engine output power is insufficient.

Reasons for high engine speed: air intake system failure, sudden increase of throttle opening, slipping or damage of air conditioning clutch, and sudden loss of engine load will also cause the speed to increase.

The engine speed is related to the number of times of work done per unit time or the effective power of the engine, that is, the effective power of the engine changes with the speed. The working condition of the engine at rated power and rated speed is called rated working condition. Speed: The engine speed can generally reach 700 rpm at idle speed and 3000 rpm at normal operation.

The reasons for the high speed of cars:

1, air intake system failure, throttle opening suddenly increased.

2, the cylinder pressure is not enough, check the piston ring and piston wear.

3, the problem of oil.

4. The air-conditioning clutch slips or is damaged, and the engine is suddenly unloaded, resulting in an increase in speed.

5. Transmission computer forced downshift or internal fault of transmission.

6, the engine output power is insufficient.
