Abstract:
A cold start control system for a vehicle having a spark ignition direct injection (SIDI) engine includes a startup control module and a fuel actuator module. The startup control module sets a mode of operation to a cold start mode. In response to setting the mode to the cold start mode, the startup control module determines target combustion parameters and a predetermined amount of fuel, wherein the predetermined amount of fuel is less than an amount of fuel required to initiate a combustion stroke of the SIDI engine. The startup control module controls injection of the predetermined amount of fuel, during cranking of the SIDI engine, based on the target combustion parameters. The fuel actuator module injects the predetermined amount of fuel, during cranking, based on the target combustion parameters.
