SYSTEM AND METHOD FOR ADJUSTING FUEL MASS FOR MINIMUM FUEL INJECTOR PULSE

摘要

A control system for an engine includes a fuel mass determination module, a mass fraction determination module, and a fuel injector control module. The fuel mass determination module determines a first minimum fuel mass corresponding to a first fuel system of the engine. The mass fraction determination module determines first minimum and maximum mass fractions based on the first minimum fuel mass and a total fuel mass. The fuel injector control module limits a first desired mass fraction based on the first minimum and maximum mass fractions, and controls a first fuel injector of the engine based on the limited first desired mass fraction.
