Abstract
A desired pulse width module determines a desired length of a single pulse of fuel for a combustion cycle of a cylinder of an engine. A multiple pulses module determines a number of pulses (N) for the combustion cycle, wherein N is an integer greater than 1. A fraction determination module determines N fractional values for the N pulses, respectively. An injector control module generates individual lengths for the N pulses based on the N fractional values, respectively, and based on the desired length. A fuel actuator module opens a fuel injector that injects fuel into the cylinder during the combustion cycle in N pulses having the individual lengths, respectively.
