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

Abstract

The invention relates to a rotor disc laminated variable adjustable combined fuel injection system, which comprises an oil tank, a fuel filter, and an oil pump. The invention is characterized in that the air inlet of engine is arranged with a fuel injector which comprises a choke and an inner oil nozzle, a distributor base connected under the choke, an one-way valve and an oil chamber connected with one side of the distributor base, an engine connected with another side of one-way valve, wherein, the invention also comprises an oil inlet nozzle, a stable pressure oil tank and a reflux nozzle communicated with the oil chamber, and a Hall rotation speed sensor arranged on the distributor base. The invention has the advantages that the fuel can be injected into the cylinder laminated variably, to control the injected fuel accurately and distribute the mixed fuel reasonably, while the fuel can be burnt quickly and completely, to improve the dynamic behavior of vehicle, reduce the fuel consumption and reduce the harmful gas.

Description

technical field [0001] The invention relates to a fuel injection device for an engine, in particular to a combined fuel injection system with variable adjustable turntable layering. Background technique [0002] 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 the carburetor-type supply system, and is increasingly used in passenger cars and light vehicle engines. 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 c...
