Air intake pressurizing method for gas engine

The invention relates to the technical field of engines, in particular to an air intake pressurizing method for a gas engine. The gas inlet end of the gas engine is connected with a liquid storage tank containing LNG. The natural gas in the liquid storage tank is stored inside in a low-temperature liquid form. The natural gas can obtain certain pressure in the process of changing from the liquid form to the gas form. The pressure can pressurize air entering an engine combustion chamber through pressurizing equipment in a controlled mode, and pressurizing of the inlet air under the condition ofidling or any rotary speed of the engine is realized. By means of the air intake pressurizing method for the gas engine, the problem that the power and torque of the gas engine modified from a combustion chamber diesel engine in the same class are lowered is solved, and the low-speed torque of the gas engine with the natural gas as the fuel can be greatly improved. 本发明涉及发动机技术领域，具体涉及种燃气发动机进气增压的方法，燃气发动机的进气端连接装有LNG的储液罐，储液罐内
