论文已在中国上海举行的2013年CIMAC大会上发表。论文的版权归CIMAC所有。Thanks to the advantages of lower harmful emissions and noise, swirl-chamber indirect injection diesel engine has been widely used in small type non-road machinery. With the implementation of harmful emission regulations on non-road machinery diesel engines, swirl-chamber diesel engine regains attention from domestic and abroad internal combustion engine industry. In order to improve the fuel economy, the authors modified a swirl-chamber diesel engine, applying conical spray in swirl-chamber to improve fuel-air mixture formation and combustion processes. A 3-D CFD software package was employed to investigate the match of the conical spray and swirlchamber and analyze the performance of the modified engine. The simulation results indicate that with the application of the conical spray on the prototype engine, the fuel economy is improved due to finer atomization of conical spray in Swirl-chamber.
