The KIVA-II code has been modified to model modern DI diesel engines and their soot and NO{sub x} emissions. Computational results are compared with measurements of (1) engine-out soot and NO{sub x} from a single-cylinder research version of the Caterpillar 3406 production diesel engine over a range of start-of-injection timings and of (2) the crank-angle-resolved NO measurements from a TACOM single-cylinder research engine. The Extended Zel`dovich model is used to predict NO and a number of soot formation and oxidation models are implemented and compared. For the Caterpillar engine, the predicted soot and NO{sub x} trade-off curve well matches the measured engine-out emissions. For the TACOM engine, the predicted NO evolution well matches the measured NO.
