Problems solved by technology
Although the method of directly injecting gasoline into the engine intake pipe has many advantages, there are still many shortcomings. The main reason is that the precise layered variable control is not carried out for each fuel injection process, and the proportion of combustible mixture in the cylinder is not distributed. Reasonable, resulting in slow flame conduction, insufficient combustion, unsatisfactory emission, poor shock resistance, easy to cause shock, and scattered components, poor integrity

The present invention relates to an integrated fuel oil stratified variable spraying device. It includes fuel oil distributor seat, pressure-stabilizing fuel oil tank, fuel oil pump seat, and fuel oil inlet tube connected with the fuel oil pump seat, fuel oil spraying nozzle connected with fuel oil distributor seat and throat tube communicated with said fuel oil spraying nozzle. It is characterized by that in the internal cavity of fuel oil distributor seat the fuel oil pump and fuel oil distributing disk are set, the internal cavity of fuel oil distributor seat is communicated with the pressure-stabilizing fuel oil tank, in the pressure-stabilizing fuel oil tank interior a motor is set, its rotating shaft is extended into the internal cavity of the fuel oil disctributor seat and is matched and connected with the fuel oil distributing disk and fuel oil pump, the fuel oil distributing holes positioned on the wheel edge of said fuel oil distributing disk are correspondently communicated with the fuel oil spraying nozzle, on the fuel oil distributor seat a Hall rotating speed sensor is set, and on the throat tube a stepmotor fit with throttle rotating shaft is set.
Description
technical field [0001] The invention relates to an engine fuel injection device, in particular to an integrated fuel stratified variable injection device. Background technique [0002] In order to solve the problem that the mass distribution of air and mixed gas in the carburetor engine is not ideal, which affects the engine's power, economical efficiency and emission improvement, people have been looking for other better mixed gas. Formation method and apparatus. In recent years, in order to meet the increasingly stringent requirements of automobile emission regulations, some countries have adopted a mixture formation system that directly injects gasoline into the intake pipe, that is, the electronically controlled injector is installed at the intake port of the engine, and is controlled by an electronic control unit. , has successfully replaced carburetor feed systems and is increasingly used in passenger cars and light vehicle engines. Although the method of directly in...
