How often does Qi Jun clean the throttle?

Qi Jun (check the transaction price | model details) The throttle is generally cleaned once every 30,000 kilometers. The main function of the throttle valve is to control the air intake according to the load of the engine. If there is no abnormal phenomenon such as jitter, there is no need to clean it. Generally, the cleaning cycle of solar terms is about 20,000-30,000 kilometers.

Of course, the cleaning time is also determined by many aspects. Such as the driving environment of the vehicle and the control mode of the EFI engine. If the vehicle works in a polluted environment (mainly inhalable particles), impurities will soon accumulate on the throttle valve, which will affect the intake of the engine for a long time, so it needs to be cleaned. This phenomenon is most obvious when starting the vehicle. For another example, some Japanese engine control systems traditionally like to calculate fuel injection and ignition timing by measuring air flow. Therefore, the accuracy of air = flow measurement is very strict.

A slight blockage can also cause the engine to work abnormally. But for some American engines, if the air flow rate is not used as the calculation basis, there will be no such great response. Therefore, different vehicles and different working environments will cause inconsistent engine throttle cleaning time. There is no regulation on how often to clean the throttle. If there is such a regulation, it is an abnormal regulation, indicating that the design of the car is flawed.

It should be noted that all vehicles that need to clean the throttle frequently are faulty vehicles. Some vehicles equipped with electronic throttle can contact the maintenance station.

Adjust through ECU software upgrade. If the problem cannot be solved by repeatedly cleaning the solar terms through the maintenance station, it is recommended to return the car or change it. (Photo/Text/Photo: Zhang Fengxue) @20 19
