Is it necessary to clean the throttle when driving to 20 thousand kilometers?

Because the throttle is the throat of the car, the mixture can not be completely burned, and it is inevitable that carbon deposits will be produced in the throttle. Since carbon deposition will occur, it is natural to clean it up in time. Generally speaking, it is recommended to clean the throttle every 65,438+0.8-23,000 km, but different models, different regions and different road conditions will be different. If you encounter problems such as cold start, secondary ignition, driving jitter, idling or low-speed flameout, and increased fuel consumption, if you can't find other reasons, you might as well clean the throttle after driving for 20,000 kilometers.

Throttle is a valve that controls air to enter the engine. After the air enters the intake pipe, it will mix with the fuel to form a combustible mixture and burn. It connects the air cleaner and the engine, so it is the throat of the engine.

After the car starts, the air will be filtered by the air filter and then come to the throttle. When air is mixed with fuel, there will definitely be 1 0,000% insufficient combustion, exhaust gas generated by insufficient combustion will remain, and carbon deposits will be formed in the intake and throttle.

In addition, long-term use of air filters will produce some impurities (especially in places with heavy smog), which will adhere to the throttle and accumulate for a long time to produce sludge, thus causing poor engine acceleration, increased fuel consumption, unstable idle speed and low speed.
