Description
Technical Field

Background
In recent years, environmental pollution and energy shortage bring a serious challenge to the development of power technology, and the national 'double-carbon' target puts higher-level requirements on the power industry. As a typical representative of high energy consumption and high pollution, the power industry must take energy conservation and emission reduction as a first mission.
The existing gas electric injection valve products are all single switch valves, and the flow regulation can be realized only by regulating the injection pulse width. Because the valve has certain time delay and poor consistency in the opening and closing stages, when the pulse width is smaller, the consistency of the flow of the fuel gas electric injection valve is obviously reduced. Meanwhile, when the engine is in an air inlet stroke, the descending speed of the piston changes along with the rotation angle of the crankshaft, and the change of the air inlet flow is consistent with the descending speed change trend of the piston according to the engine principle.
Because the flow is the definite value after traditional gas electricity injection valve opens, in the course of the work, the change of air mass flow and gas flow is unmatched, asynchronous, will cause the gas mixture inhomogeneous, the burning is not abundant, and pollutant discharge is higher. Therefore, the research and development of the gas-flow-controllable fuel electronic injection valve have great practical significance for improving the fuel economy of gas engines and dual-fuel engines and reducing pollutant emission.
