Abstract
An engine control system for a spark-ignition direct-injection (SIDI) engine comprises a fuel control module delays injection of fuel during engine cranking until fuel pressure is greater than a predetermined fuel pressure, retards ignition timing, and retards fuel injection until near top dead center (TDC). An exhaust cam phaser module retards an exhaust cam phaser after starting and oil pressure is greater than a predetermined oil pressure.
