Abstract

Early Direct Injection Premixed Charge Compression Ignition (EDI PCCI) combustion is a promising concept for the diesel combustion. Although EDI PCCI assures very low soot and NO xemission levels, the injection is uncoupled from combustion, which narrows down the operating conditions. The main purpose is to analyse the effect of mixing. A multi-zone model is presented with the use of detailed chemical models. The paper presents the effects of parameters, like number of zones and chemical model, on emissions and ignition delay. A dedicated set of experiments is also utilised to assess the quality of the model.
