Abstract

The invention discloses a pre-atomization structure of a single-hole atomization fuel injector, which comprises a pipe body, a mounting sleeve, a valve seat, a diverter piece, a flow-through piece, a swirl piece and a metering piece. A splitter groove is arranged on the splitter sheet, which can split the fluid beam into several strands. A flow hole is provided on the flow sheet, which can further restrict the flow of the flow flow. There are swirl holes and swirl slots on the swirl sheet. After the diverted fluid passes through the swirl slot, the bottom of the swirl slot is blocked by the metering sheet, causing violent impact and turbulent flow, which converges into the swirl holes. When the turbulent fluid beam passes through the swirl hole and then through the metering hole, the atomization effect will be significantly improved, the liquid atomization will be more thorough, the particle size of the atomized particles will be finer, and the fuel atomization effect will be improved. It is beneficial for mixing with air and full combustion, avoiding carbon deposits in the cylinder, and improving the cleanliness of vehicle emissions. The invention also discloses a single-hole atomizing fuel injector, the beneficial effects of which 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 atomizing 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 system,...
