The impact of not changing the gasoline filter:
1. The function of the gasoline filter is to filter gasoline. It is generally integrated with the fuel pump and installed in the fuel tank. There are also fuel pumps that are separately connected to the gasoline pipe of the car chassis. There is generally a filter in the fuel tank to filter large impurities. The gasoline filtered by the oil filter is pressurized by the fuel pump, then filtered through the gasoline filter and then injected into the cylinder by the fuel injector for combustion;
2. The reality is that gasoline is not pure, there are many impurities in it, and impurities can also enter when the fuel tank cap is opened during refueling or maintenance. The filter in the fuel tank can only filter large impurities, and is powerless for relatively small particles. And these relatively small impurities are likely to damage the oil pump;
3. The fuel injector is a high-precision and easy-to-clog object. If it is blocked, it will cause increased fuel consumption, unstable idle speed and decreased power. Therefore, it is necessary to install a gasoline filter in the fuel supply system. It is designed to filter relatively small impurities and particles in gasoline. After it acts for a period of time, there will be many impurities inside, which will affect the flow of gasoline and oil pressure. Therefore, it has a certain service life and life span. It needs to be replaced when it reaches the service life or mileage.
