Main Problems of Using Alternative Fuels in Automotive Engine

Physical and chemical characters, using economy, comparison of emission test results and some re- lated technical problems for main alternative fuels are more comprehensively presented and the development of alternative fuels both at home and abroad is described in this paper. It is pointed out that the use of alternative fuels is of very importance to saving energy, protecting environment, developing new energy sources and increasing thermal efficiency.This paper also puts forward some conversions in engine construction while adapting some alternative fuels.
