Problems solved by technology

Due to the large flow rate and load, most of the on-off valves driven by electromagnets are currently used to control the flow rate through pulse width modulation. The gas flow output by this method fluctuates greatly, which reduces the dynamic performance of the system on the one hand. , on the other hand, it causes unnecessary waste of energy

Abstract

The invention provides an engine gas fuel continuous flow valve which comprises a first-stage electromagnetic actuator, a pressure regulating valve, a first-stage valve body, a first-stage valve cover, a second-stage electromagnetic actuator, a second-stage valve body, a second-stage valve cover and a Venturi tube type nozzle. The first-stage electromagnetic actuator and the second-stage electromagnetic actuator are placed in the first-stage valve body and the second-stage valve body respectively, an inter-stage chamber is formed between the first-stage valve body and the second-stage valve body, the first-stage electromagnetic actuator and the second-stage electromagnetic actuator are perpendicular to each other, and the Venturi tube type nozzle is used in cooperation with an actuating rod of the second-stage electromagnetic actuator. According to the continuous flow valve, the gas fuel injection flow can be accurately controlled, so that gas is injected at low-pressure sound velocity. The fuel gas injection flow is continuously changed, it is unnecessary to conduct reciprocating motion hundreds of times within one minute like a pulse width modulation control type nozzle, a series of problems of pipeline fuel gas pressure fluctuation, pipeline resonance harm, low part reliability and the like caused by switch control are effectively avoided, the reliability is good, and the requirement for fuel gas quality is low.

Description

technical field [0001] The invention belongs to the technical field of engines, in particular to an engine gas fuel continuous flow valve. Background technique [0002] While automobiles bring great convenience to people, they also bring unavoidable environmental protection and energy crisis problems to human society, and pose unprecedented challenges to the research and design of engines. Faced with this severe challenge, on the one hand, countries around the world have enacted more and more stringent fuel consumption regulations and emission regulations; Fuel, dimethyl ether fuel and synthetic diesel, among which gaseous fuels such as natural gas with abundant reserves and clean combustion are the most widely used. Compared with traditional gasoline and diesel internal combustion engines, gaseous fuel internal combustion engines can reduce oil demand, reduce carbon dioxide and harmful exhaust emissions. [0003] The continuous flow valve is a kind of gas regulating valve...
