A Computer Model for the Assessment of Engine Control System Parameters 940484

A computer model has been developed to investigate ways of improving the control of the mixture strength supplied to a spark ignition engine during transients and steady-state operation. The model comprises four sub-models, which calculate the gas dynamics, the response of the sensors, the fuelling logic (mass flow and speed-density) and the air-fuel ratio of the running engine.
Comparisons are made between different fuelling logics and sensor responses for various transient modes (fast and slow accelerations) and for a range of engine operating conditions.
