Summary on Grant Application Form |

The existing spark ignition engine simulation at Oxford (ISIS) is for a homogeneous charge, but it does have a facility for modelling the burnt gases in a series of zones. The need is to model a non-homogeneous charge, and this would be done in the first instance by assigning different compositions to each zone. The NOx modelling would show how different forms of charge stratification affect emissions and fuel economy. Experimental data for validation of the model would come from the optical access Gdi engine that is currently under construction at Oxford.Professor Raine has undertaken a preliminary investigation to extend the spark ignition engine model to incorporate CO kinetics. The objective here was to determine whether CO kinetics are of importance under these engine operating conditions and whether CO formation in the bulk gas may be a source of the CO emissions. A 36 reaction skeletal chemical kinetic scheme has been applied to the CO kinetics and then reduced to a smaller number of reactions in order to improve computation speed whilst still retaining the important features of the chemistry. Results from these preliminary calculations will enable a suitable reduced kinetic scheme to be identified for incorporation into ISIS.EngProg\
