How often should the throttle body of a car be cleaned?
1 Answers
The throttle body should generally be cleaned every 20,000 kilometers. The throttle body is a controllable valve that regulates the air entering the engine. After the air enters the intake pipe, it mixes with gasoline to form a combustible mixture, which then burns to generate power. Failure to clean the throttle body for an extended period can lead to errors in the throttle opening angle and allow air containing impurities to enter the engine combustion chamber. Both of these outcomes can cause abnormal engine operation, primarily manifesting as unstable idling, a sudden sensation of throttle closure while driving, and a reduction in power. In severe cases, it may even result in difficulty starting the engine and increased fuel consumption. Frequency of throttle body cleaning: How quickly the throttle body gets dirty depends on various factors, including the quality of the air filter, the brand and quality of the engine oil used, driving conditions, air temperature, engine operating temperature, and driving habits. Points to note for throttle body cleaning and prevention: The primary cause of throttle body deposits comes from engine oil vapors, followed by airborne particles and moisture. This means that when using a qualified air filter and removing the crankcase ventilation tube, the throttle body will get dirty at a much slower rate. The crankcase houses the crankshaft and is connected to the oil pan at the bottom. The operating temperature in this area ranges between 100°C and 180°C.
