THE PERFORMANCE ANALYSIS OF A SI ENGINE USING GASOLINE, LPG AND BLEND OF GASOLINE AND LPG

Abstract

Conventional fuels such as gasoline and diesel are causing serious environmental issue due to their high amount of pollutants. Moreover, emissions such as nitrogen oxides (NOx), Carbon monoxides (CO), sulphur oxides (SO2), and so on have an adverse impact on the human body. Therefore, alternative fuels such as LPG are being considered to replace the role of conventional fuels in order to reduce harmful emissions to a safer level. LPG is commonly used as a cooking fuel in India and is widely available commercially in small sized portable cylinders. Recently a large number of SI Engines have been converted to run on LPG mode, which gives significant reduction in exhaust pollutants. It is also found more economical but in most of the cases it results in about 10 -15% power loss. In this work a study was conducted on the use of LPG in conventional four stroke gasoline engines. The engine was tested using LPG, gasoline and with gasoline and LPG-air mixture; so that comparative study o...
