Synchronous layered displacement-variable electric fuel-injection equipment

Abstract

The invention relates to an electric injection device with synchronous delamination variable, comprising support, motor, injector, end cover and injector nozzle, characterized in that a distributing plate is set between support and end cover, the distributing plate is mated with the rotating shaft of motor; a first injection nozzle corresponding to the outlet of injector is set at the connection position between support and injector; more than one injection hole is set on the distributing plate at least and the distributing hole is corresponding to the first injection hole; a second injection hole corresponding to the outlet of injector nozzle is set at the connection position between end cover and injector nozzle and the second injection hole is corresponding to the distributing hole on the distributing plate. The distributing hole is set on the circle corresponding to the first injection hole on the support. The injector and the motor are connected with the electric control cell. Work is done under the control of electric control cell and fuel oil is injected into the cylinder with delamination and variability in jetting process so that the proportion of combustible mixture is reasonable, the burning is full filled, the power performance of automobile is improved, oil consumption is decreased and drainage is decreased.

Description

technical field [0001] The invention relates to an engine fuel injection device, in particular to a synchronous layered variable electric fuel injection device. Background technique [0002] Due to the simple structure of carburetor, convenient use and low cost, some car engines still use carburetors at present. The main disadvantage of the carburetor engine is that the mass distribution of the air and the mixture is not ideal, which affects the power of the engine, the improvement of the economy and the improvement of the emission. For this reason, people have been seeking other better mixed gas forming methods and devices. 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...

AI Technical Summary

Problems solved by technology

Although the method of directly injecting gasoline into the engine intake pipe has many advantages, there are still many deficiencies. The main reason is that the secondary injection process of fuel has not been accurately stratified and variable controlled, and the proportion of combustible mixture in the cylinder is unreasonable, resulting in The flame conduction is slow, the combustion is insufficient, the emission is not ideal, and the shock resistance is poor, which is easy to cause shock
