During the operation process of thediesel engine, the diesel will be polluted because of the impurities in the fuel system and the dust in the air. The filter can filtrate 90%of the mechanical impurities in the diesel to keep the fuel clean by the greatest extent, which can prolong the lifetime of the engine. So it isessential to have filters.With the common rail system adopted, which will go through high-pressure pump, common rail tube oil atomizer after filtration and it will creat the closed cycle fuel feed system with sensor and ECU, which can make the engine operate steadily.

While the modern injection system has the high accuracy, whose spay hole is so small that it can not place even three hairs. A good filter can improve the quality of fuel in the injection system,  which can prolong the lifetime of the system and it can drive longer mileage. So the filter is enssential to any fuel system.

The operating principle of filter:

The high quality filter can efficiently protect the commonrailsystem of the dieselengine , lower the cost of maintenance. Meanwhile, the users should be drawing off the water, checking on it regularly, and timely replace it in order to insure the effect of the filter.

The function of the filter:

 The filter can minimize the wearing to ensure the stable function of engine, increasing the working efficiency of the engines, lowering the oil consumption and cost of Vehicle usage.
