Abstract
A system and method of controlling J/L specific energy deposition in accordance with either measured or estimated values of engine or vehicle operational parameters in order to optimize emission reduction versus energy cost over a driving cycle. A typical strategy varies the J/L specific energy deposition in relation to a measured or estimated value of a relevant parameter such as engine-out NO concentration to improve energy cost versus emission performance over a driving cycle.
