One of the most effective methods to reduce air pollution by SI engine exhaust emission is the use of alcohol though due to its hygroscopicity it makes unstable blends with gasoline. The present paper describes the impact of gasoline-methanol blend on major characteristics of an engine including fuel consumption am ecological parameters. A blend of 75 per cent gasoline and 25 per cent methanol was tested which was mixed in such as to ensure its long-term stability. The data on fuel consumption, engine power, torque, exhaus emission (CO, CO 2, CH, NOX O2) and air-fuel ratio of motor vehicles working on pure gasoline (95 RON) am gasoline-methanol blend (M25) are presented. The results of measurements demonstrate much lower exhaus emission for engine s operating on blend M25.
