Why cleaning the throttle will lead to high fuel consumption?

In fact, this is a normal phenomenon, and car owners don't have to worry about it, because after the cleaning is completed, the throttle must be matched with the computer again, and the normal operation of the engine can be guaranteed after the matching is completed, and the phenomenon that the fuel consumption and the speed of the car will increase after the throttle is cleaned will disappear.

First of all, after cleaning the throttle valve, the relevant matching processing was not done, which led to the computer detection program still adjusting the fuel injection quantity according to the original throttle valve calculation. Under normal circumstances, the car will gradually adapt after driving for a period of time, and the fuel consumption will return to normal.

Secondly, because the throttle valve has not been cleaned for a long time, the position of the throttle valve and throttle arm is worn too much. At this time, after the throttle valve is cleaned, the clearance is larger, so the fuel consumption will become higher.

Thirdly, the throttle valve is too dirty, and the intake branch pipe and valve foot position must be dirty. For the car, if it is not thoroughly washed, these three positions are in a balanced state. Once the throttle is cleaned, the balance is broken, resulting in higher fuel consumption after the throttle is cleaned.

Causes and cleaning frequency of throttle: the throttle is the external window of the engine and often comes into contact with impurities in the air. The inside of the throttle valve is airtight, which is easy to cause dirt accumulation and indirectly leads to the reduction of engine efficiency. Therefore, in order to ensure the running efficiency of the automobile engine, the throttle valve should be cleaned once when the automobile travels 20-40 thousand kilometers.
