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. A 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.
