【 摘 要 】

Methanol, as a promising carbon-neutral fuel, has become a research hotspot worldwide. In this study, pure gasoline and gasoline blended with five different volume ratios of methanol (10%, 20%, 30%, 50%, and 75%) were selected as test fuels, which were referred to as M0, M10, M20, M30, M50, and M75. The experiments on carbon and pollutant emissions and performance were carried out on a passenger vehicle with gasoline direct injection (GDI) turbocharged engine using the steady-state, new European driving cycle (NEDC), and acceleration approaches. The results show that under steady-state conditions, as the methanol blending ratio increases, the volume of fuel consumption increases. Compared with pure gasoline, the equivalent fuel consumption and the CO₂ emissions are reduced by 0.95 L/100 km (10.6%) and 18.95 g/km (9.6%) in maximum extent by fueling M75, respectively. In the NEDC, the CO₂ emissions of M30 are reduced by 5.46 g/km (3.7%) compared with pure gasoline. After blending methanol in gasoline, CO emissions increase, and the emissions of NO_x, THC, and PM decrease. The acceleration time is shortened with the increase of blending ratio of methanol. The application of methanol reduces the combustion CO₂ emissions by 10% and improves the pollutant emissions.
