| ABSTRACT |
|
This study deals with the result of exhaust emissions and performance calculated by simulation of the fuel injection characteristics of the inline injection system in a marine diesel engine. The emissions are calculated through nonequilibrium by using the extended Zel'dovich kinetic mechanism for NOx and equilibrium method for OH, CO, H2, H and soot concentrations. Comparisons of the model predictions with the experimental values show reasonable agreement. Detailed prediction results showing the sensitivity of the model by injection rates are presented and discussed. |
