Authors Abstract
Content
A method is presented for determining an optimum engine calibration that maximizes fuel economy for the CVS-H cycle subject to a set of emission constraints. The method combines the results of a powertrain simulation with steady state engine dynamometer emissions and fuel flow data to project cycle emission and fuel economy values. Dynamic Programming is used to allocate emission contributions among selected speed/load points to maximize projected cycle fuel economy. The corresponding engine calibration is then directly inferred from the optimum emission allocation. Typical results for 2.3 liter and 400 CID engines are presented.
