In the present investigation a new phenomenological model
for Quiescent and Swirl Type Direct Injection Diesel Engines
has been developed.
The model enables prediction of engine cylinder pressure,
fuel injection and evaporation rates, air entrainment rate into
fuel sprays, heat release rate, heat transfer and mean cylinder
gas temperatures and exhaust smoke level.
A soot model is proposed based on chemical kinetics and a
turbulent mixing rate concept. The model predictions are verified
with several experimental data.
The predictions are made over a range of engine speed, load,
injection timing, boost pressure and intake swirl level.
Comparison with available engine experiments is in general
