摘要
A control system includes an engine activation module and a fuel control module. The engine activation module determines whether predetermined operating conditions of a spark ignition and direct injection (SIDI) engine are met and activates an engine preparation mode when the predetermined operating conditions are met. The fuel control module controls a fuel injector to deliver a preparation pulse to a cylinder of the SIDI engine when the engine preparation mode is activated. The fuel injector delivers the preparation pulse by opening for a pulse width to inject fuel directly into the cylinder when the SIDI engine is stopped.
