Embodiment 1

[0029] Embodiment 1: see Figure 4 , the fuel filter device 13 of the fuel filter system is connected in parallel between the oil suction filter 18 and the oil coarse filter 19, and the circuit of the combustion chamber 22 of the electronic fuel injection system is connected with the node between the fuel filter device 13 and the oil suction filter 18, and works The process is: the fuel in the fuel tank 17 is sucked into the fuel filter device 13 after passing through the oil suction filter 18, and the fuel filter device 13 intercepts and filters large particles, small particles, tiny particles and water in the fuel; A part of the finished fuel oil enters the coarse oil filter 19, and another part of the fuel oil is sucked away by the fuel filter device 13, and is filtered and purified again; the filter layer of the coarse oil filter 19 intercepts and filters large particles and moisture in the fuel oil; After the filtered fuel oil enters the fuel pump 20, it is pressurized an...

Embodiment 2

[0030] Example 2: see Figure 5, the oil inlet of the fuel filter device 13 of the fuel filter system is connected with the fuel tank 17, and the oil outlet is connected with the oil inlet of the coarse oil filter 19 and the circuit of the combustion chamber 22 of the EFI system. The specific working process is: The fuel in the tank 17 is sucked into the fuel filter device 13, and the fuel filter device 13 intercepts and filters large particles, small particles, tiny particles and water in the fuel; part of the fuel filtered by the fuel filter device 13 enters the oil coarse filter In 19, another part of the fuel returns to the fuel tank through the oil return pipeline; the filter layer of the coarse oil filter 19 intercepts and filters large particles and water in the fuel; after the coarsely filtered fuel enters the oil pump 20, it is pumped into the oil In the fine filter 21, the olein filter 21 intercepts and filters tiny particles in the fuel; the filtered fuel enters the...

Embodiment 3

[0031] Example 3, see Figure 6 , the oil inlet and outlet of the fuel filter device 13 of the fuel filter system communicate with the fuel tank 13 respectively. Large particles, small particles, tiny particles and moisture in the fuel; the fuel filtered by the fuel filter device 13 returns to the fuel tank 17, so that the fuel in the fuel tank 17 is repeatedly filtered in a short time; at the same time After the fuel oil in the fuel tank 17 passes through the oil suction filter 18, it is sucked in the oil coarse filter 19, and the filter layer of the oil coarse filter 19 intercepts and filters large particles and moisture in the fuel; the fuel oil after the coarse filtration enters the oil pump 20 Finally, it is pressurized and pumped into the olein filter 21, and the olein filter 21 intercepts and filters tiny particles in the fuel; the filtered fuel enters the combustion chamber 22 of the EFI system under the action of the pump pressure of the oil pump 20 to carry out Comb...

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...
