How is it that the speed of Transit diesel engine comes up but it can't?

Park the car on a flat place and don't affect other vehicles. When the handbrake is easy to use, tighten the handbrake to ensure the braking of the car. Then start, step on the clutch and put into first gear. Loosen the clutch and refuel at the same time. Under normal circumstances, the engine of the vehicle should be turned off. There is no flameout and the engine speed is still high, indicating that the clutch is not easy to use.

2, the cause of the clutch oil pump

In addition, if the car has a clutch pump, check the oil return of the pump and the oil return and air return of the booster.

3, the cause of the air intake system

It should be judged whether the air intake system is in good condition. If it is in good condition, it is necessary to consider whether the air intake system needs to be cleaned, and remove the air filter and blow it clean. If it is difficult to blow clean, it should be replaced.

4. Reasons for throttling

Check whether the throttle valve is clean, and further check the intake valve and intake manifold. Carry out proper cleaning when necessary.

5, automatic gearbox reason

You can do a road test to determine whether the automatic gearbox is faulty, and set the joystick to different positions to make the car run. If the engine speed suddenly rises when the automatic transmission rises to a certain gear, but the vehicle speed does not increase accordingly, it means that the gear has slipped. The easier it is to increase the engine speed when slipping, the more serious it is.

6. Causes of hydraulic oil in automatic transmission

Check the hydraulic oil level in the automatic transmission. If the oil level is too low or too high, adjust it and see if the automatic transmission is still slipping. If it still slips, check the quality of hydraulic oil. If the hydraulic oil is brownish black or smells burnt, it means that the friction plate or brake of the clutch or brake is burnt. At this time, the automatic transmission should be removed for maintenance.
