By installing a diesel after-treatment system such as DPF and/or SCR catalyst, temperature of exhaust gas from a tail pipe decreases due to higher heat capacity of those systems. Consequently, a proportion of the gas supersaturating state increases, and it may result in an emission of visible white smoke especially in the case of a heavy duty diesel engine at cold operation range. In this study, a CFD simulation was carried out to predict the white smoke from the tail pipe. The validity of the CFD simulation approach was evaluated in a rig test prior to the simulation and the utility of the simulation results were examinated in on-vehicle tests.
