Fuel oil filtering system

Abstract

The invention relates to a fuel oil filtering system which comprises a fuel oil tank, an oil absorption filter, an oil coarse filter, an oil pump, an oil fine filter and a combustion chamber of an electronic injection system, wherein the oil absorption filter is arranged in the fuel oil tank, and is sequentially connected with the oil coarse filter, the oil pump, the oil fine filter and the combustion chamber of the electronic injection system; and a fuel oil filtering device is arranged between the fuel oil tank and the combustion chamber of the electronic injection system, and is of an integrated structure composed of the oil pump and a filter. According to the invention, an electromotor, the oil pump, a controller and the filter are integrated into a whole, the fuel oil in an engine oil tank is circulated and filtered repeatedly, thus the fuel oil entering the combustion chamber of the engine has high cleanness; and the fuel oil filtering system of the engine has the advantages of high filtering accuracy, high filtering and water removing efficiency and the like, and has great significance for the improvement of the reliability of the engine and the improvement of automobile emission environment protection standard.

Description

technical field [0001] The invention relates to a fuel filter system. Background technique [0002] Automobile exhaust is the main source of air pollution, and the particulate matter in automobile exhaust directly endangers human health. In order to reduce the pollution of the atmospheric environment caused by automobile exhaust emissions, the World Environmental Protection Organization has put forward higher requirements for the engine emission standards of the automobile industry. Among them, the EU countries require the implementation of the Euro 5 emission standards in 2010, and the domestic requirements also start in 2010. Full implementation of China V (equivalent to Euro 3 emission standards). [0003] In order to be able to adapt to the new emission standards, major engine manufacturers at home and abroad are actively developing a new generation of engines, among which the most used technologies are the electronically controlled unit pump system and the electronica...
