What should I do if the nozzle is dirty? How to clean it, master

It is generally recommended to go to a maintenance franchise store for disassembly and cleaning. Because the currently used fuel tank is not equipped with oil drain bolts, oil cannot be drained from the lowest part of the fuel tank. The inside of the oil tank is too dirty, and it is not good for the nozzle if it is not cleaned for a long time, which is easy to cause blockage. Cleaning method of dirty nozzle: 1. Most nozzles can be cleaned once every two years or 50 thousand to 80 thousand kilometers, depending on the quality of gasoline in the area where the vehicle is used; 2. There are two ways to clean the oil nozzle: one is to remove and clean it, and the other is to remove and clean the oil nozzle of the engine, which must be cleaned. Unclean engine nozzle will affect vehicle fuel consumption; 3. A series of failure problems such as insufficient power, idling jitter and vibration occur. Personally, the biggest influence is fuel consumption. After all, the oil price is so expensive now, it still hurts a little. It is necessary to advocate regular cleaning of fuel nozzles and refueling at large gas stations. Because the poor quality of gasoline affects the carbon deposition or damage of the injector, it is a bit not worth the candle.
