This article presents ways to improve the operation performance and environmental safety of natural gas vehicles with a universal fuel supply system. In this, two passenger vehicles with a universal supply system were studied, and the traction-speed characteristic of the vehicles was determined by the acceleration indicator during the pilot test. Fuel economy characteristics were determined by calculating the distance traveled by the amount of gas fuel in the gas cylinder tank. Also, by adjusting the gas-gasoline modes in the engine to the conditions of operation, the methods of reducing gasoline consumption and thus increasing the environmental safety of the vehicle are mentioned.
