Abstract

The present invention relates to a diesel engine control system and methods for substantially operating a diesel engine at stoichiometric fuel to air ratios. The system may include a fuel processor which receives instructions for a desired engine output and current operating conditions. The fuel processor may also generate fueling instructions for the cylinders, including: substantially regulating fuel delivery into to a first group of cylinders at or near stoichiometric fuel levels, and substantially disabling fuel injection into to a second grouping of cylinders. The number of cylinders being fueled, and therefore undergoing a combustion event corresponds to the desired engine output. This may be calculated by dividing the desired output by the power provided by one cylinder operating at substantially stoichiometric fuel levels. The number of cylinders receiving fuel may be varied over a succession of engine revolutions such that the actual average engine power output conforms to the desired output.
