Abstract
A control system for an engine includes a transient operation detection module, an injection determination module, and an injection control module. The transient operation detection module detects whether the engine is operating in a transient state. The injection determination module, based on an elapsed time since a fuel request and at least one of a plurality of engine operating parameters, at least one of (i) increases a number of fuel injections per combustion cycle to N, and (ii) adjusts periods for each of the fuel injections, wherein N is an integer greater than or equal to two. The injection control module controls fuel injection during the transient state based on at least one of (i) N fuel injections per combustion cycle and (ii) the adjusted periods.
