Method for controlling a fuel system of a multiple injection system

摘要

A method for controlling a fuel system of a multiple injector engine provides a primary fuel injector and a secondary fuel injector which are both connected in fluid communication with an air stream flowing to a combustion chamber of the engine. Based on the total magnitude of fuel required to be injected into the air stream and as a function of the engine speed and percent load of the engine, first and second shares of the total magnitude of fuel are determined for the primary and secondary fuel injectors. The primary and secondary fuel injectors are then caused to inject their respective shares of the total fuel magnitude into the air stream, with the primary and secondary shares being determined as a function of engine speed and percent load of the engine.
