In the whole automobile industry, diesel engines are becoming the main power of automobiles due to the advantages of high thermal efficiency, good adaptability, large output power and the like. Compared with other internal combustion engines, the diesel engine has a series of advantages of high power, high fuel oil heat efficiency, long service life, good starting performance, low emission of carbon monoxide (CO) and Hydrocarbon (HC), low oil consumption and the like. However, the biggest problem in the application of the diesel engine is that the emission of particulate matters is more, and is 30-60 times of that of the gasoline engine. With the increasing importance of environmental protection issues, the reduction of harmful emissions from diesel engines is becoming an important direction in the development of diesel engines in the world today. Accordingly, various governments have generally enacted corresponding regulations limiting emissions from diesel engines. The use of diesel filters will be a necessary trend in order to meet emissions legislation requirements.
The fuel filter is used for filtering out the impurities in the fuel and supplying clean fuel to the engine. If the fuel oil is filtered poorly, the impurities in the gasoline easily block the tiny pore passages in the carburetor, so that the carburetor works poorly and the combustible mixed gas becomes thin; the wear of the precision matching parts is easy to accelerate, and the pressure of the pump oil is reduced. If the water and colloid in the fuel oil enter the cylinder, the combustible gas mixture can be burnt badly, and the dynamic property of the engine is reduced. The gasoline filter is generally only one stage and is arranged between a gasoline tank and a gasoline pump or between the gasoline pump and a carburetor. Because the diesel engine supply system is provided with three precise coupling parts, the requirement on the cleanness degree of the diesel oil is higher, the content of colloid in the diesel oil is higher, and in order to improve the filtering efficiency, the diesel oil filter is generally provided with two or more stages, namely a diesel oil coarse filter and a diesel oil fine filter, which are also called as an oil-water separator and a diesel oil fine filter; the diesel engine is respectively arranged between a diesel oil tank and an oil delivery pump, and between the oil delivery pump and an oil injection pump, and some diesel engines are also provided with a precipitation cup for precipitating moisture and impurities in the diesel oil.
