Abstract：To improve engine combustion efficiency and effectively reduce pollutant emissions,the physicochemical properties of alcohol fuels,such as methanol,ethanol,and butanol,and the impacts of alcohol fuels on the performance of engines and fuel cells are summarized.The analysis results show that alcohol fuels can reduce engine pollutant emissions and improve combustion efficiency.And the impact of alcohol fuels on the performance of dual-fuel engines varies with operating conditions,and the comprehensive performance of engines can be effectively improved by synergistically optimizing the fuel injection strategy and EGR rate.When methanol and ethanol are used as fuel cell fuels,the permeability of the proton exchange membrane needs to be improved.The cost of catalysts should be comprehensively considered when the reformed methanol fuel cell is used.
