Abstract
A process and apparatus for reducing nitrogen oxide emissions in a genset comprising an engine and a generator and a shaft coupled to the engine and generator. The apparatus directs the generator to reduce load on the shaft while directing the engine to seek a steady state shaft speed for a desired energy transfer to the shaft when a shaft speed correction signal representing a shaft speed correction to reach the desired energy transfer meets a criterion.
