CO-PM Modeling for Particulate Matter Emission of Diesel Engines

In this study, a phenomenological model, that predicts the particulate matter emission (PM) of diesel engines, has been formulated. The CO-PM model is based on the formation mechanisms of PM and carbon monoxide (CO) of diesel engines. It can predict the emission concentration of PM via the emission concentration of CO. The calculation method of the model is simple and quick. To validate the model, experiments were carried out in two research diesel engines. Comparisons of the model results with the experimental data show good agreement. The model is useful for computer simulations of electronically controlled diesel engines, as well as electronic control unit (ECU) designs for diesel engines.
