With the upgrade of national emission regulations, a diesel engine fuel system mostly adopts a high-pressure common rail technology, a high-pressure common rail pump in a high-pressure common rail component provides ultrahigh-pressure diesel, and an electric control oil injector realizes the regular and quantitative injection of the diesel. When impurities in fuel oil enter the high-pressure common rail part, particle abrasion of a plunger and barrel assembly of the high-pressure common rail pump, particle abrasion of a needle valve and barrel assembly of the electronic control oil injector and particle abrasion of an oil nozzle can be caused, so that the atomization of the oil injector is poor, the oil injection quantity is increased, further, the faults that the engine emits black smoke and the power is insufficient are caused, the cylinder of the engine is pulled seriously, and great economic loss is caused to a user.
The size and the quantity of impurities in domestic diesel oil cannot be controlled, the problem that fuel oil impurities added into a fuel tank are excessive inevitably exists, and meanwhile, a domestic commercial vehicle inevitably runs in mining areas, mountain areas and other areas with large dust, and the working environment is poor, so that tiny impurities enter the diesel oil in the process of supplying air to the fuel tank of the commercial vehicle.
At present, a passive diesel oil filtering system is adopted on a commercial vehicle, diesel oil directly enters a high-pressure common rail component of a diesel engine after passing through a fuel delivery pump, a fuel oil coarse filter and a fuel oil fine filter from a fuel tank, and the diesel oil is filtered once in each filtering component of the passive diesel oil filtering system. When the quantity of diesel oil impurity in the fuel tank is too much, the passive diesel oil filtering system can not solve the problem that the quantity of diesel oil impurity entering the high-pressure common rail component exceeds the standard.
