As we all know, the quality of domestic gasoline is uneven, and the maintenance of fuel filters can not be ignored. The function of the fuel filter is to filter impurities in automobile fuel and make the fuel supplied to the engine purer.
How often does the fuel filter need to be changed?
It is recommended to replace the fuel filter every 10000 km, and replace the built-in fuel filter in the fuel tank every 40000 - 80000 km. The maintenance intervals of different models may vary slightly. Please know when your car needs to be replaced and maintained through the "self-service" function.
During major maintenance, the fuel filter is generally replaced at the same time as the engine oil, engine filter, and air filter.
The disassembly and replacement of the fuel filter are relatively complex. Do not operate it yourself easily. It needs to be operated and installed by professionals in special stores.
The function of fuel filter
Remove the iron oxide, dust, and other solid impurities contained in the fuel, prevent the fuel system from blocking (especially the fuel injection nozzle), reduce mechanical wear, ensure the stable operation of the engine and improve the reliability. The structure of the fuel injector is composed of an aluminum shell and supports stainless steel inside. The support is equipped with a high-efficiency filter paper component, and the filter paper is in a chrysanthemum shape to increase the flow area. The EFI filter cannot be used in common with the filter of the carburetor. Because the EFI filter often bears the fuel pressure of 200 - 300kPa, the pressure strength of the filter is generally required to reach more than 500kPa, while the filter of the carburetor is not necessary to reach such high pressure.
The necessity of changing the fuel filter
The fuel filter can be divided into gasoline filters and diesel filters according to different fuels. Gasoline filter is mainly used in household vehicles, and gasoline filter can be divided into the built-in type and external type of fuel tank.
With the increase in vehicle service age, the increase in driving mileage (reference, picture, and inquiry), and the long-term operation of the fuel filter, reaching a certain life cycle, will lead to weak acceleration, increased fuel consumption, increased noise, reduced handling performance, etc.
Precautions for fuel filter purchase
- Before purchasing goods, please be sure to verify the model, displacement, and other information of your car to ensure that you buy the correct model of accessories. You can check your car maintenance manual or use the "self-service" function of carefree.com.
- During major maintenance, the fuel filter is generally replaced at the same time as the engine oil, mechanical filter, and air filter.
- Select a high-quality fuel filter. Poor fuel filter often leads to poor fuel supply, insufficient vehicle power, and even flameout. Impurities are not filtered, and the oil circuit and fuel injection system will be corroded and damaged after a long time.
- When you feel that the vehicle speed is significantly reduced, the engine acceleration is poor, and the vehicle is unable to drive, you should think that the fuel filter may have been blocked and need to be checked in time.
