Abstract

The invention relates to an electronic injection type automotive umbrella-shaped spiral ethanol oil injector assembly and mainly solves the problem of the existing electronic injection type automotive umbrella-shaped spiral ethanol oil injector assembly of being low in atomization degree and fuel burning ratio in use. The electronic injection type automotive umbrella-shaped spiral ethanol oil injector assembly comprises an oil inlet pipe, a valve rod, a valve base, a cap and an oil outlet pipe. An oil inlet is arranged on the lateral surface of the oil inlet pipe, the valve rod is arranged in the oil inlet pipe, and an oil outlet pipe is arranged on the valve base and corresponds to the valve rod. The cap is arranged on the other side of the valve base corresponding to the valve rod, a first through hole is arranged at the central position of the cap of the valve base, a second through hole corresponding to the first through hole is arranged at the central position of the valve base, a guide plate is arranged between the valve base and the cap, and a plurality of spiral holes which are circumferentially distributed along the center of the guide plate are arranged on the guide plate. The electronic injection type automotive umbrella-shaped spiral ethanol oil injector assembly has the advantages of being good in atomization degree and sufficient in fuel burning.

Description

technical field [0001] The invention relates to the field of engine fuel injectors, in particular to an umbrella-shaped helical ethanol fuel injector assembly for electric spray automobiles. Background technique [0002] The injector itself is a normally closed valve, and the opening and closing of the valve is controlled by the up and down movement of the valve needle. When the ECU issues a fuel injection command, its voltage signal will cause current to flow through the coil in the fuel injector, generating a magnetic field to attract the valve stem, allowing the valve to open so that fuel can be sprayed out from the fuel injection hole. The biggest advantage of injection fuel supply is that the control of fuel supply is very precise, so that the engine can have the correct air-fuel ratio in any state, not only to keep the engine running smoothly, but also the exhaust gas can meet the environmental protection regulations. [0003] As one of the key components of the EFI e...
