With the increase of vehicle service life, a certain amount of carbon deposit will be generated inside the engine, which needs to be cleaned regularly by the owner. How often do you need to clean the throttle valve and nozzle? 1. When the vehicle travels from 20,000 km to 40,000 km, the accelerator of the vehicle needs to be cleaned once. Regular cleaning of the accelerator can reduce the generation of carbon deposits in the engine, reduce the fuel consumption of the vehicle, and make the vehicle more stable and the power output response timely when the owner uses the vehicle. 2. If the vehicle has been used for 2 years or 60,000 kilometers, you need to clean the throttle of the vehicle. If the fuel nozzle of the vehicle fails or is damaged, it will cause great damage to the engine of the vehicle, and it is likely that the vehicle will be short of cylinders.
