Numerical studies for combustion processes and emissions in the DI diesel engines using EGR Kwon, Y.D.; Lee, J. C.; Kim, Y. M.; Kim, S. W.;
The effects of exhaust gas recirculation on diesel engine combustion and soot/NOx emissions are numerically studied. The primary and secondary atomization is modelled using the wave instability breakup model. Autoignition of a diesel spray is modelled using the Shell ignition model. Soot formation is kinetically controlled and soot oxidation is represented by a model which account for surface chemistry. The NOx formation is based on the extended Zeldovich NOx model. Effects of injection timing and concentration of and CO on the pollutant formation and the combustion process are discussed in detail.
