Abstract

The invention discloses a single-hole atomizing injector and a post atomizing structure thereof. The post atomizing structure comprises a tube body, a valve base, splitters, swirling flow plates and ameasuring piece, a first mounting groove is formed in the top of the valve base, a second mounting groove is formed in the bottom of the valve base, the first mounting groove is communicated with thesecond mounting groove through valve openings, the measuring piece is attached to the bottom surface of the second mounting groove, the swirling flow plates are attached to the bottom surface of thefirst mounting groove, and the splitters are tightly attached to the surfaces of the swirling flow plates; through-flow holes and splitter grooves are formed in the splitters; swirling flow holes andswirling flow grooves are formed in the swirling flow plates; a measuring hole is formed in the measuring piece. Projections of the swirling flow grooves and the splitter grooves on the water level are overlapped, fluid is split and then enters the swirling flow grooves, a turbulent flow or a swirling flow is formed at the bottom of each swirling flow groove, the atomization effect is obviously improved when the fluid passes through the measuring hole, atomization is more thorough, the particle size of atomized particles is finer, fuel oil atomization effect is improved, and mixing with air and sufficient combustion are facilitated. The invention further discloses the single-hole atomizing injector. The single-hole atomizing injector has the above mentioned advantages.

Description

technical field [0001] The invention relates to the technical field of fuel injectors, in particular to a rear atomization structure of a single-hole atomizing fuel injector. The present invention also relates to a single-hole atomizing fuel injector comprising the above-mentioned rear atomizing 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 sys...
