Abstract

Abstract: A type of military vehicle diesel engine is taken as the research object for heat balance experiment in a simulated environment of an elevation of 4 500 m. The heat distributions of the diesel engines fueled with automobile diesel fuel and oligomeric polyoxymethylene dimethyl ether oxygenated fuel under the same power condition are compared and analyzed. Results show that the ignition delay period is shorten, the pressure rising rate is decreased, the heat losses in coolant and exhaust are decreased, and the heat efficiency is improved when the diesel engine is fueled with the oxygenated fuel in the simulated plateau environment. The oxygenated fuel could alleviate the engine burning delay and thermal load aggravation in plateau environment effectively. These results suggest that the oligomeric polyoxymethylene dimethyl ether is a suitable fuel for diesel in plateau environment. Key

Key words: dieselengine, plateauenvironment, oxygenatedfuel, heatbalance
