SYSTEM AND METHOD FOR CONTROLLING FUEL INJECTION CHARACTERISTICS IN AN ENGINE

摘要

An engine control system (10) includes first (14) and second (16) control modules. The first control module (14) determines a fuel combustion parameter. The second control module (16) 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 (18), (ii) a time at which a fuel injector (22) starts delivering the volume of fuel to the cylinder (18), and (iii) a fuel pressure in a fuel rail (32) (Fig. 1).
