Abstract: Under the background of "Carbon Peak and Carbon Neutral", the diversification of fuels, as well as the deep integration of electric technology and engine technology, has become one of the strategic directions more in line with China's national resource situation. Among them, methanol has great potential as an alternative fuel due to its mature preparation technology and wide range of sources. Based on a methanol hybrid vehicle (using a methanol/gasoline dual-fuel supply system with hybrid technology), the article investigates its performance in terms of alcohol consumption in the world light duty vehicle test cycle (WLTC) and on real roads. The test results show that the energy utilization efficiency of the methanol hybrid system is 36.55%. As the proportion of actual vehicle speed greater than the standard speed gradually increases, the overall driving energy of the WLTC cycle gradually increases, and the alcohol consumption increases as a result. The methanol consumption levels in the urban and suburban areas are in the range of 8.83 L/100 km and 8.65 L/100 km, respectively, when the vehicle is not air-conditioned in the actual road.
