초록
Many countries of the world has been devoting a lot of effort to reduce carbon emission. In orderto reduce carbon emission, the high efficiency engine has been studied in the automotive industry. Ofthese, the spread and research of the diesel engine in Europe center are active. However the combustioncharacteristic of diesel engines have disadvantages of much NOx and soot emissions. In this study, theoptimum regeneration point of the forced regeneration type DPF(Diesel Particulate Filter) that wasequipped in medium-duty diesel vehicles using a mechanical fuel injection system have studied. DPF thatis applied to the medium-duty diesel vehicle has a bent inlet pipe. The flow distribution characteristics ofDPF according to the influence of the bent pipe have investigated. The flow distribution characteristics ofDPF according to variation of the engine operating condition is considered to be useful data In order todecide the optimum regeneration point.
