대형디젤기관 연소특성에 관한 시뮬레이션 연구

A Simulation Study on the Heavy-Duty Diesel Engine Combustion Characteristics

It is a present situation that the control on automobile emission is getting more restrictive and also the regulations for emission are changing greatly up to level of those advanced foreign countries. Specially, it has been many years that exhaust gases from gasoline automobile rather than from diesel is the major object concerned by Korea and other countries, and it is strongly required on the reduction techniques on harmful NOx and PM among those compositions. Thus, this research focused on the combustion characteristics prediction and the target of this research conducted with numerical simulation to get engine performance and the characteristics of emission in heavy-duty turbo-diesel engine. Furthermore, the results obtained under different conditions with the numerical simulation using KIVA-3.
