A SI Engine Indicated Characteristics Determination for Gasoline and Methane Operation

Abstract

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