Single-hole atomization oil sprayer and front atomization structure thereof

Abstract

The invention discloses a front atomization structure of a single-hole atomization oil sprayer. The front atomization structure of the single-hole atomization oil sprayer comprises a pipe body, a mounting sleeve, a valve base, a flow separation piece, a flow passing piece, a cyclone piece and a metering piece. A flow separation groove is formed in the flow separation piece for dividing a fluid beam into multiple parts. A flow passing hole is formed in the flow passing piece for further performing the flow separation limiting on the divided fluid. The cyclone piece is provided with a cyclone hole and a cyclone groove; after the divided fluid passes through the cyclone groove, the bottom of the cyclone groove is shielded by the metering piece to generate acute impact and to form turbulent flows; and the turbulent flows are gathered in the cyclone hole. When the fluid beam forming the turbulent flows passes through a metering hole after passing through the cyclone hole, the atomization effect is obviously improved, the liquid atomization is more thorough, the particle size of atomization particles is finer, and the fuel atomization effect is improved; and when the structure is appliedto an engine cylinder, mixing with air and full combustion are facilitated, accumulation of carbons in the cylinder is prevented, and the vehicle discharge cleanness is improved. The invention further discloses the single-hole atomization oil sprayer; and the beneficial effects are as above.

Description

technical field [0001] The invention relates to the technical field of fuel injectors, in particular to a pre-atomization structure of a single-hole atomization fuel injector. The present invention also relates to a single-hole atomized fuel injector comprising the above-mentioned pre-atomized structure. Background technique [0002] With the development of China's machinery industry, more and more machinery and equipment have been widely used. [0003] In the automobile manufacturing industry, there are thousands of types of auto parts, such as fuel injectors for engines. The fuel injector belongs to the fuel injection system, and the fuel injection system refers to the fuel supply device that uses the fuel injector to inject a certain amount of fuel directly into the cylinder or the intake passage under a certain pressure. According to the different types of injected fuel, it can be divided into gasoline injection system, diesel injection system, gas fuel injection syste...

AI Technical Summary

Problems solved by technology

However, the electronically controlled fuel injector in the prior art has a circular or annular shape of the nozzle hole, so the fuel atomization effect is not good, the particle size of the atomized particles is large, it is easy to form a liquid beam, and the atomization fineness is low
