【Meiruier FIlter】The working principle of diesel filter

Oil pump pump out of the diesel oil into the casing through the interface, and then penetrate the filter and into the filter cavity, the final output through the tubing interface to the fuel injection pump, in the process, the mechanical impurities in diesel and dust are filtered , Water precipitation in the shell, in order to achieve the effect of filtering diesel. After the normal operation of the diesel engine, the filter in the use of 5,000 km to achieve the best results. With the precipitation of water and filter impurities increased, the filter must be replaced periodically, the replacement cycle should be depending on the actual use of diesel quality may be, under normal circumstances, the use of diesel filters less than 10,000 km.
Part of the diesel filter in order to extend the service life, so the filter at the bottom of the design of a drainage plug, after a certain period of time, you can unscrew the plug to exclude precipitation in the filter water.

The working principle of gasoline filters
Gasoline from oil pump into the oil pipe shell, and then infiltration of the filter into the filter cavity, finally the oil output through the tubing interface to the carburetor, during this process, the mechanical impurities and dust in the petrol will be filtered , in order to achieve the effect of filtering gasoline. After the gasoline engine work function well, the filter will achieve the best effection after using 5000 km. With the impurities increased, the filter must be replaced regularly, the replacement cycle should be based on the actual using the quality of gasoline , under normal circumstances, the use of gasoline filters should be less than 10,000 km.

The maintenance of fuel filter 
After filter plug, the filter resistance increases, poor gasoline flow, resulting in fuel in the fuel filter up to the liquid level. From the filter housing circumstance , you can observe inside the oil level rise, so you can determine whether the filter plug.
After filter element plug , the lack of oil, the engine power down, the vehicle driving weak, lower speed. A car speed up to 100km / h, it can be reduced to the speed of 70 ~ 80km / h, or even lower, the engine speed is bad. Audi, Santana and Jetta and other passenger cars should be replaced petrol filter in every 15,000 km.
