System and method for adjusting fuel mass for minimum fuel injector pulse widths in multiple fuel system engines

System and method for adjusting fuel mass for minimum fuel injector pulse widths in multiple fuel system engines

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 determinat...

description 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.
