Vibration directly affects the power index and fuel economy index of the gas generator. Due to the large differences in the composition and knock resistance of different gas fuels, the performance indicators of gas generators also vary greatly. The fuel with methane as the main component has high calorific value and good knock resistance. When using this fuel, the average effective pressure of a two-stroke gas generator can reach pe=0.7～0.8 MPa, and a four-stroke gas generator pe=1.4～1.6 MPa; the heat consumption per unit power ge=9000～10000 kJ/(kW· Time). When burning non-methane fuel, the performance of the gas generator is lower than the above-mentioned index, and sometimes even much lower.
