ABSTRACT:
A system and method for controlling an internal combustion engine during starting use position sensor information in addition to cylinder combustion information to transition from simultaneous fueling to sequential fueling by selecting a cylinder to receive a first sequential fuel injection. Embodiments include a system and method for controlling a sequentially fueled port injected internal combustion engine that contingently select a cylinder to receive a first sequential fuel injection based on position information indicating that the cylinder received a simultaneous fuel injection during its intake stroke. Engine rotational speed is monitored to detect combustion and determine which cylinder fired first. A first sequential fueling pulse is provided to the contingently selected cylinder unless a preceding cylinder in the firing order fires first.
