PERFORMANCE AND NO X MODEL OF A DIRECT INJECTION STRATIFIED CHARGE ENGINE

A model has been developed to predict the performance and NOx emission of the Texaco stratified chrge engine. The fuel mixing process is described by a jet mixing model and the equations are solved in a cylindrical coordinate system with a non-uniform pressure field. Nitric oxide emissions are calculated by using the extended Zel'dovich kinetic mechanism with a steady state assumption for the N concentration and equilibrium values used for H,O, O2 and OH concentrations. The model computes combustion rates, heat transfer and NOx based on the same jet mixing processes at each stage.
