The gas stored in the gas tank 1 is transported through the gas pipe 3. The adjusting valve 4 on the outer wall of the gas pipe 3 can control the opening degree of the valve according to the actual factors of the power demand of the charging station, the gas reserve and the equipment running state, control the flow of the gas to the gas engine 5. After the gas engine 5 receives the gas from the gas pipe 3, the combustion process is started immediately.
