At present, marine engines are basically internal combustion engines, and mainly use two fuels, namely gasoline and diesel. As a fuel, there is a certain requirement for the quality and cleanliness of the oil. Due to refining processing, the finished fuel oil contains a certain amount of impurities, moisture and colloid. 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 diesel oil is high, the content of colloid in the diesel oil is high, and in order to improve the filtering efficiency, the diesel oil filter is generally provided with two stages or more than two stages, and is divided into 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.
