Fuel supply system for gasoline engine

Abstract

The invention discloses a gasoline engine fuel supply system, comprising a fuel tank, the inner surface of the fuel tank is provided with a liquid level sensor, and the outer surface of the upper end of the fuel tank is provided with a fuel tank cover and an oil level gauge, and the outer surface of one end of the fuel tank is fixed It is connected with a No. 1 oil guide pipe, and the outer surface of one end of the No. 1 oil guide pipe is provided with a gasoline filter, the outer surface of one end of the gasoline filter is provided with an oil inlet pipe, and the outer surface of the other end of the gasoline filter is provided with an outlet An oil pipe, an oil chamber is arranged inside the fuel filter, and a buffer chamber is arranged on the outer surface of the upper end of the oil chamber. A fuel supply system for a gasoline engine according to the present invention is provided with a buffer chamber, a static eliminator and an activated carbon net, which can increase the contact area between the gasoline and the filter screen, accelerate the filtering speed, and remove the The electrostatic ions can also enhance the strength of air filtration and bring better prospects for use.

Description

technical field [0001] The invention relates to the field of fuel supply, in particular to a fuel supply system for a gasoline engine. Background technique [0002] Gasoline engine fuel supply system is the most important system inside the car. Its task is to prepare a certain amount and concentration of combustible mixture according to the requirements of various engine working conditions, and supply it to the cylinder so that it can be ignited and burned when the compression is nearing the end. The expansion does work, and finally, the supply system discharges the waste gas generated by combustion into the atmosphere; the existing fuel supply system has certain disadvantages in use. First, the filtration speed of gasoline through the gasoline filter is relatively slow, and in some special In some cases, it cannot meet the actual use requirements. Secondly, after a long-term use of the carburetor, there will be a certain amount of static ions inside, which will pose a certa...

[0002] Gasoline engine fuel supply system is the most important system inside the car. Its task is to prepare a certain amount and concentration of combustible mixture according to the requirements of various engine working conditions, and supply it to the cylinder so that it can be ignited and burned when the compression is nearing the end. The expansion does work, and finally, the supply system discharges the waste gas generated by combustion into the atmosphere; the existing fuel supply system has certain disadvantages in use. First, the filtration speed of gasoline through the gasoline filter is relatively slow, and in some special In some cases, it cannot meet the actual use requirements. Secondly, after a long-term use of the carburetor, there will be a certain amount of static ions inside, which will pose a certain safety hazard. In addition, the air filter has a small filtering strength for the air, so it is not It is beneficial to protect the fuel supply system and has a certain impact on the use process. Therefore, we propose a fuel supply system for gasoline engines
