Diesel engine throttle failure phenomenon?

There are many phenomena of throttle failure: for example, it cannot be started or the throttle does not return after starting; Black smoke, high fuel consumption, high idle speed and poor acceleration are all signs that the throttle is broken.

Throttle is a controllable valve that controls air to enter the engine. After the air enters the intake pipe, it will be mixed with gasoline to form a combustible mixture, and the combustion is successful. It connects the air filter and the engine block, and is called the throat of the automobile engine. Whether the acceleration of a car is flexible or not has a lot to do with the dirt of the throttle. Cleaning the throttle can reduce fuel consumption and make the engine flexible and energetic.

It is worth mentioning that proper and standardized throttle cleaning can ensure the normal operation of the engine, but the cleaning must be controlled. Excessive cleaning will lead to premature scrapping of the throttle, and frequent cleaning will lead to the special coating in the throttle cavity being washed away gradually. If the inner cavity loses its coating, it is more likely to cause greasy adhesion and form a vicious circle, and the final result is scrapping.
