| 초록 |
Three-dimensional computation by KIVA-3A and STAR-CD is preformed for in-cylinder flow and fuel spray behavior in an HSDI diesel engine. For accuracy and efficiency of computation the flow output from STAR-CD is converted to a restart input file of KIVA-3V after intake valve closure by a converting program. The simulation results for two different nozzle types with delayed injection timings are compared with the wall impinging effect taken into account. Parametric study is performed for different fuel injection timings and injection durations in KIVA-3V. Results show the influence of the fuel sprays in terms of premixed combustion characteristics and reduced NOx emissions of an HSDI diesel engine. |
