Abstract

To evaluate the potency of alkyl ethers as alternative fuel source in compression ignition engines, a standard combustor model has been developed. The combustion characteristics of alkyl ethers- dimethyl ether and diethyl ether as potential fuels in compression ignition engines are analyzed. The standard single cylinder 0.9 liter-diesel engines with unit aspect ratio and compression ratio of 15:1 has been incorporated into the model with stratified intake of fuel and air. The comparison between the fuels has been made on several parameters specifically the fuel-air mixture homogeneity, the heat release rates, thermal contours, the residual fraction of reactants and products of combustion reaction inside the combustor, turbulence intensities which indicate that among the alkyl ether based fuels, DEE has considerable potential as a substitute to heavy diesel oil
