Abstract
A control system includes a starter control module, a mode setting module, a throttle control module, and a fuel control module. The starter control module initiates cranking of a spark ignition direct injection (SIDI) engine in response to user actuation of an ignition switch. The mode setting module sets a mode of operation to a coldstart mode when an engine coolant temperature is less than a predetermined temperature during the cranking. The throttle control module allows a throttle valve to be biased to a predetermined open position when the SIDI engine is off and, in response to the setting of the mode to the coldstart mode, selectively closes the throttle valve relative to the predetermined open position during the cranking. The fuel control module, in response to the setting of the mode to the coldstart mode, disables direct injection of fuel for a first combustion event during the cranking.
