A SI engine performance parameters determination for gasoline and methane operation

Abstract

The present paper presents a study whose objective is to determine the performance parameters of an external mixture formation and spark-ignition engine when running on methane fuel. The experiments were carried out using optimum adjusting parameters for engine operation on methane and gasoline fuels. The parameters measured and determined are: brake specific fuel consumption, mean effective pressure, brake power, thermal efficiency, volumetric efficiency and etc. over the entire engine speed range. An analysis of the obtained results is made, comparing the obtained effective parameters at the operation of internal combustion engines with alternative fuel - methane and traditional fuel - gasoline.
