Abstract: A system according to the principles of the present disclosure includes a desired injection duration module, a fuel control module, and a throttle control module. The desired injection duration module determines a desired injection duration. The fuel control module compares the desired injection duration to an injection duration limit and controls a fuel injector of an engine based on the injection duration limit when the desired injection duration is greater than the injection duration limit. The throttle control module controls a throttle of the engine based on the injection duration limit when the desired injection duration is greater than the injection duration limit.
