Theoretical and Experimental Studies on The Combustion of Synthetic Fuels in Spark Ignition Engines.(Dept.M)

Abstract

A theoretical and experimental investigation on the performance and emission of spark ignition engine have been made using gasoline, alcohol and gasoline-alcohol mixture as fuels. A thermodynamic model has been developed with superimposed pseudo-kinetic NO and CO formation. This has been used to compute estimated performance and emission data for a spark ignition engine. The model has also been used to compare the prediction performance and emission data when operating the engine with methanol, ethanol and gasoline fuels. \nA series of an experimental tests were carried out on a single cylinder spark ignition engine to confirm the theoretical results of the mathematical model. Comparison of results indicates that alcohol seems to be a viable alternative fuel to gasoline with respect to efficient, operational and emission considerations.
