Filton fuel filters are featured with high efficiency of filter medium and filter accuracy. It owns optimal filtration and water separation functions that can help to improve fuel cleanliness and fuel efficiency. Good raw material offers a longer replacement cycle and longer service life. It can effectively protect engine performance, reduce wear and tear and reduce maintenance costs.
There are different types of fuel filters. For example, the fuel filter of Mazda 6 is a built-in type, which is linked with the gasoline pump; while the fuel filter of Geely Boyue is an external type, which can be directly observed from the chassis, so the replacement cycle of external and internal fuel filters must be different. Generally, the replacement cycle of the external fuel filter is about 20000-40000 km, while that of the internal fuel filter is between 60000-80000 km. It is generally not recommended to replace it at 100000 km. After all, it is the part where the fuel is filtered, so there is no need to support it for too long.
First, when the power of the car engine drops. Even if the blockage degree of the gasoline filter is relatively light, it has a great impact on the engine power, especially when it is uphill or overloaded. If your fuel filter has not been replaced for a long time at this time, you should consider whether this is the reason.
Second, when the car is hard to start. Sometimes the blockage of the fuel filter will make it difficult for the fuel to atomize, which makes it difficult for the car to start when it is cold, and the ignition can be done only after many times.
Third, when the engine is shaking at idle speed. If other reasons are eliminated, it can be judged that the fuel filter is blocked, and the blockage of the fuel filter will make the fuel not be fully atomized, so the phenomenon of shaking at idle speed will occur.
Fourth, when you feel like a car is shrugging. If the fuel filter is seriously blocked, the phenomenon of shrugging is very obvious when driving at ordinary times, especially when uphill.
Fuel filters are generally not washable. Most engines are equipped with disposable non-washable paper filter elements. Fuel filters are changed together when the oil is changed. They can not be washed clean, since there will be impurities left.
Most of the filters used in car engines are paper filter elements and sealed with a hard plastic shell. The internal oil level can be observed from the outside, so whether the filter is blocked can be judged by observing the rise of the oil level. If the filter adopts a metal shell, the oil pipe shall be removed, and the oil supply quantity of the pump shall be used to check and judge whether the filter is blocked. You can also remove the filter and blow it from the nozzle of the oil inlet pipe joint port on one side of the oil tank for inspection: when blowing, if the filter is completely not ventilated or forced to blow before ventilation, it indicates that the filter has been blocked.
A car can run without a fuel filter. But without the fuel filter, the fuel injector will be blocked, resulting in a lack of cylinder or poor atomization, resulting in insufficient power and increased fuel consumption.
