How often does Dongfeng Nissan clean the throttle in Qi Jun?

The throttle in Qi Jun is usually cleaned 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 shaking, there is no need to clean it. The cleaning cycle of general solar terms is about 20,000-30,000 kilometers.

Of course, the cleaning time is also determined by many aspects. For example, the driving environment of the vehicle, the control mode of the EFI engine and so on. If the vehicle works in a relatively 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 and need 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 time by measuring air flow. Therefore, the measurement accuracy of air = flow is very strict.

A slight blockage can also cause the engine to work abnormally. But for some American engines, there is no such great response without air flow as the calculation basis. Therefore, the working environment of different vehicles is different, which will cause the engine throttle cleaning time to be inconsistent. There is no regulation on how often the throttle should be cleaned. If there is such a regulation, it is an abnormal regulation, indicating that the car is defective in design.

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

Adjust by upgrading the electronic control unit software. 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.
