Description

Novel electronic injection throttle valve

Technical Field

The utility model relates to the technical field of throttle valves, in particular to a novel electronic injection throttle valve.

Background

Electrospray is a type of engine that differs considerably from the engine in the method of operation used. When the engine is started, the throttle valve is generally not needed to be stepped on, the throttle section or the throttle length is changed to control the fluid flow, the throttle valve has no flow negative feedback function, the speed instability caused by load change cannot be compensated, and the engine is generally only used in occasions with little load change or low requirements.

The original air intake system for the motorcycle uses a carburetor to control the concentration of a mixer, but the fuel combustion is not very sufficient, the carburetor mainly depends on the suction force formed by the movement of a piston to suck the oil of the carburetor into a mixed gas through a venturi and then enter a cylinder, when the motorcycle works, the carburetor can provide the mixer no matter whether the device works or not, thus certain waste is formed, the electronic injection system can stop oil injection when the electronic injection system does not work, the fuel can be effectively saved, and a common throttle valve can not control the speed of the piston in the cylinder.

For this reason, it is highly desirable to provide a novel electronic injection throttle valve.
