How often do you clean the nozzle throttle valve?

Under normal circumstances, the car throttle is cleaned every 20,000 to 50,000 kilometers. Among them, the nozzle does not need to be cleaned if there is no abnormality, or it needs to be cleaned every 20,000 to 60,000 kilometers. If you don't clean it for a long time, it will cause the engine power of the car to drop and consume more oil, so regular cleaning is very important. Fuel injector is the key component of automobile engine. If it is not cleaned for a long time, it is easy to block or leak. Once blocked, it means that the sprayed gasoline can't be atomized normally, causing black smoke in the exhaust pipe of the car. At the same time, it will also lead to the lack of cylinder in one cylinder of the engine, which will make the engine shake obviously. There are many reasons for nozzle blockage, such as carbon accumulation in engine or impurities in fuel, which leads to nozzle channel blockage. When the car runs for a period of time, the fuel system will also accumulate deposits. Therefore, it is recommended to clean the fuel injector regularly to avoid causing greater damage to the vehicle.
