Abstract: In order to achieve carbon neutrality in transportation sector, this study examines the performance of three different fuels in a spark ignition (SI) engine from green and renewable methanol and hydrogen: M0G100 (pure gasoline), M10G90 (90 % gasoline mixed with 10 % methanol), M30G70 (70 % gasoline mixed with 30 % methanol), and M30G70 with hydrogen (7.5 % hydrogen energy share in blended fuel). The study explores the synergistic optimization influences of adding methanol and hydrogen on performance of a gasoline SI engine thorough comparative analysis. The results show that using hydrogen and methanol can improve combustion process of the gasoline engine. The coefficient of variation (COV) of peak combustion pressure for the test gasoline engine using different fuel mixtures (M0G100, M10G90, M30G70, and M30G70/hydrogen) is 16.25 %, 17.58 %, 18.75 %, and 9.55 % respectively. Similarly, the COV of indicated mean effective pressure for these mixtures is 7.6 %, 11.41 %, 33.45 %, and 4.41 % respectively. Additionally, using M30G70 with hydrogen in gasoline engine shows a 14.3 % decrease in fuel consumption and a 12.5 % increase in indicated thermal efficiency. The carbon dioxide (CO2) emissions of the test gasoline engine with M10G90, M30G70 and M30G70/hydrogen fuels are respectively reduced by 7.37 %, 26.78 % and 33.27 % compared to the gasoline engine.
