Abstract: A method of controlling fuel delivery in a fuel injection system capable of performing a split injection includes comparing at least one engine operating temperature to a temperature threshold, and disabling split injection when at least one engine operating temperature exceeds the temperature threshold. Disabling split injection in this manner enhances cold temperature engine operation while providing a single injection at higher operating temperatures, as desired. Further, an engine (12) and a computer readable storage medium (28) having information stored thereon representing instructions executable by an engine controller (22) for comparing at least one engine operating temperature to a temperature threshold are also provided. The computer readable storage medium instructions disable split injection when at least one engine operating temperature exceeds the temperature threshold.
