Power control mechanism of gas engine

Abstract

The invention provides a power control mechanism of a gas engine. The power control mechanism comprises a supercharger and a intercooler, wherein the mixed gas outlet end of the supercharger is connected with the gas inlet end of the intercooler through a first gas path, and the air outlet end of the intercooler is connected with a second air path and is used for providing pressurization and cooling air and a fuel gas mixture for a gas engine cylinder; and the power control mechanism further comprises a flow regulating valve, the gas inlet end of the flow regulating valve is connected to the second gas path in parallel through a third gas path and is positioned between the intercooler and the gas engine cylinder, and the gas outlet end of the flow regulating valve is connected with the mixed gas inlet end of the supercharger in parallel through a fourth gas path. The power control mechanism has the advantages that the structure is simple, the use is convenient, the fluctuation range ofthe engine is small, the service life of the supercharger can be effectively reduced, and the maintenance cost is reduced.

Description

technical field [0001] The invention relates to the field of gas engines, in particular to a power control mechanism of a gas engine. Background technique [0002] The air and gas mixture entering the supercharger of the front-end system of the gas engine is pressurized, and after being cooled by the intercooler, it enters the cylinder of the gas engine through the throttle valve to burn and perform work. At present, all gas engines control the speed and power of the gas engine by adjusting the throttle opening. However, when the throttle is used to control the power of the gas engine, the throttling loss of the air and gas mixture at the throttle is large, and the opening of the throttle (full open or fully closed) leads to fluctuations in the amount of air and gas mixture entering the cylinder of the gas engine The range is large, and the fluctuation range of engine power and speed is large, and it is easy to cause surge of the supercharger of the front-end system, which ...
