터보과급 및 EGR을 사용하는 직접분사식 디젤엔진의 연소특성에 미치는 Ar과 He첨가의 영향

The combustion characteristics of DI Diesel engine using turbo charging and EGR are numerically studied. Computations are carried out for the wide range of turbocharged pressures, EGR ratios, and Ar/He dilution. Numerical results indicate that the Ar/He dilution in the intake gas significant-ly influence the engine performance, the spray combustion process, and the pollutant formation.
