AB - The present work deals with a numerical investigation on an experimental single cylinder direct injection Diesel engine. Calculations are carried out with Kiva3v2 code using multidimensional detailed chemistry. The study was carried out on predicted CO, and NOx emission levels by the engine cylinder before exhaust valve opening. Correlations proposed for predicted NO, CO, and NOx levels function of fuel, O2, N2 concentrations and the maximum in-cylinder pressure rather than temperature. Predicted values of averaged pressures, O2, CO, and CO2 levels in the exhaust manifold were validated by the measured ones for a set of five loads at 1500 rpm. CO, NO, and NOx concentrations at the exhaust obtained by calculations lies perfectly with measured values. Otherwise, numerical simulations lead us to analyze injection timing, duration and fuel amount injected effect on the engine performances, ignition delay, combustion duration as well as CO and NOx emission levels.
