Abstract
An engine control system includes first and second control modules. The first control module determines a fuel combustion parameter. The second control module determines a fuel delivery parameter based on the fuel combustion parameter. The fuel combustion parameter includes at least one of (i) a total amount of heat released by a volume of fuel during a combustion cycle and (ii) a rate at which heat is released during the combustion cycle. The fuel delivery parameter includes at least one of (i) a duration of time over which the volume of fuel is delivered to a cylinder, (ii) a time at which a fuel injector starts delivering the volume of fuel to the cylinder, and (iii) a fuel pressure in a fuel rail.
