Embodiment Construction

[0009] The present invention will be further described in detail below in conjunction with the accompanying drawings of the specification.

[0010] Gasoline engine fuel supply without return device, including fuel tank 1, fuel pump 2, fuel filter 3, fuel pipe 4, fuel pressure regulator 5, fuel injector 6 and fuel rail 7, fuel pump 2 is placed in fuel tank 1 , The fuel pump 2 is connected to the fuel filter 3. The fuel filter 3 can effectively remove harmful particles and moisture in the fuel gas system of the engine. The fuel filter 3 and the fuel rail 7 are connected with a fuel pipe 4, which uses high pressure The performance pipeline, the fuel rail 7 is equipped with multiple injectors 6, which can atomize gasoline particles and evenly distribute the oil mist more effectively. The fuel pipe 4 between the fuel filter 3 and the fuel rail 7 is also connected with a split fuel pipe 41. The split fuel pipe 41 is connected to a fuel pressure regulator 5. As a fuel pressure regulator...

Abstract

The invention discloses a non-fuel-return fuel supplying device of a gasoline engine. The non-fuel-return fuel supplying device comprises a fuel tank, a fuel pump, a fuel filter, a fuel pipe, a fuel pressure regulator, a plurality of fuel ejectors and a fuel rail, wherein the fuel pump is placed in the fuel tank and is connected with the fuel filter, the fuel filter and the fuel rail are connected through the fuel pipe, and the fuel ejectors are mounted on the fuel rail. Due to the adoption of the non-fuel-return fuel supplying device of the gasoline engine, disclosed by the invention, the use ratio of gasoline is high, and the engine is more stable and is higher in safety.

Description

Technical field [0001] The invention relates to the technical field of automobiles, in particular to an oil return device of a fuel engine. Background technique [0002] The task of the automobile fuel supply system is to atomize and evaporate (vaporize) gasoline and evenly mix it with air in a certain proportion to form a combustible mixture. Then, according to the requirements of various engine working conditions, supply different quality and gas into the engine cylinder. Different amounts of combustible mixed gas can be ignited and burned near the end of compression to expand and perform work. At present, most gasoline engine fuel supply systems use an oil return system. This will cause the used oil to contaminate the unused oil, reducing the quality of the oil and the efficiency of reuse. Summary of the invention [0003] The object of the present invention is to provide a gasoline engine fuel supply without oil return device to solve one or more of the above-mentioned existi...
