Comparison of CO2 Emission between Methanol and Gasoline Internal Combustion Engine

Abstract

The internal combustion engine, as a huge amount of global thermal machinery, serves a wide range of industries. At the present stage, internal combustion engines will still play an irreplaceable role for a longer period of time. Taking into account the trend of CO2 emissions in China in recent years, this paper briefly analyzes the impact of adopting methanol fuel and traditional gasoline fuel on carbon emissions. The results show that the reasonable optimization of vehicle energy structure is very important to realize energy saving and emission reduction and reduce atmospheric CO2 compared with traditional fuel vehicles.
