Abstract
Methods and a system are provided for controlling fuel injection in a vehicle engine. The system specifically relates to an engine fueled with both port and direct fuel injectors. In one example, a method may include delivering a first portion of fuel via port injection during a first injection window, and subsequently delivering a second portion of fuel directly during a second injection window before the engine exits cranking speeds.
