What will happen if the car throttle is not cleaned?

Failure to clean the throttle for a long time will lead to an error in the throttle opening, and air with impurities will enter the combustion chamber of the engine. These two results will lead to abnormal engine operation, mainly manifested in unstable idle speed, sudden feeling of throttle when driving, reduced power, and even difficult starting and increased fuel consumption.

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.

Cleaning frequency

How long the throttle will be dirty depends on the quality of the air filter, the brand and quality of the engine oil, the condition of the driving section, the temperature, the working temperature of the engine, driving habits and so on.

Even for individuals, it is impossible to determine the time to clean the throttle with a fixed number of kilometers. The interval between cleaning the throttle for the first time in a new car is the longest. Later, due to the continuous condensation of oil and gas in the crankcase ventilation pipe and intake port, the cleaning frequency will increase, and different weather conditions will also affect the dirty speed of the throttle.
