It is said that it is easy to buy a car, difficult to maintain a car, most car owners know that the car needs to be maintained, but the specific maintenance is not very clear, only know the oil maintenance to be done every year, replace the air and air conditioning filter, but ignore the existence of the fuel filter.
First: the role of the fuel filter element
The main function of the fuel filter element is to filter out the impurities mixed with gasoline, play a role in protecting the oil pump nozzle, cylinder liner, piston ring and other components, while reducing mechanical wear, avoiding fuel system blockage, ensuring stable engine operation, and improving the safety of the car.
Two: the type of fuel filter element
1. Divided according to the model
(1) Gasoline filter element
The gasoline filter element used in gasoline vehicles is called the gasoline filter element, and the gasoline filter element is divided into two types: carburetor type and electric injection type, the carburetor filter element adopts a nylon shell, and the electric injection filter element uses a metal shell.
(2) Diesel filter element
Used in diesel vehicles is called diesel filter element, diesel filter element is divided into two types of replaceable and spin-on type, because the diesel engine oil supply system is extremely afraid of water, so the water filtration function of the diesel filter element must be good.
2. Divided according to the installation method
(1) External fuel filter element
Most cars use an external filter element, which is easier to replace.
(2) Built-in fuel filter
The filter element is located in the oil tank, which is not only complicated to replace, but also often much more expensive than the external one.
Three: the impact of long-term non-replacement of fuel filter elements
1. Decreased power
If the fuel filter element is not replaced for a long time, impurities may block the fuel injection nozzle, which will lead to poor passage of gasoline and cannot supply fuel in time, which will lead to a decrease in the power of the car. The power becomes worse, which will naturally affect our travel problems, and sometimes it is not necessarily possible to overtake if you want to overtake, and it is depressing to think about it.
2. Increased fuel consumption
The fuel filter element has not been replaced, will make the oil circuit is not smooth, the oil pressure is not sufficient, and finally the oil pressure is too low will lead to an increase in fuel consumption, fuel consumption is still a common concern of the problem, sometimes the sudden increase in fuel consumption, it is likely to be caused by the fuel filter element.
3. Increased carbon deposits
The filtration effect of the fuel filter element is not good, the impurities in the gasoline can not be filtered, it will flow to the cylinder, when the gasoline combustion is incomplete, it is very easy to cause more carbon deposits, cleaning carbon deposits is also a big cost Oh, and carbon deposits will further affect the operation of the engine.
Four: When to replace the fuel filter?
In order to ensure the normal operation of the filter element, it is recommended to replace the new filter element according to the time in the maintenance manual, and in the normal car environment, it can be replaced once in 30,000 kilometers. You can also choose when to replace the fuel filter according to the actual use of the car.
Summary: The fuel filter element is used to filter the impurities in the gasoline, therefore, we should pay attention to the regular gas station to refuel, unqualified gasoline will directly affect the service life of the fuel filter element.
