The article describes the technical characteristics for two gasoline engines that are converted to methane fuel. The study was carried out on the basis of mathematical modeling in the Diesel-RК program. It is shown that the conversion of gasoline engines to methane leads to a power reduction in the range of 7.5% with a decrease in specific fuel consumption to 12%, as well as a reduction in NOx emissions by 2–3 times. It is revealed that an increase in the compression ratio to 15 leads to an increase in the power and environmental friendliness of the gas piston engine.
