    摘要： During start-up of an in-cylinder fuel injection spark ignition engine (1), an engine controller (21) calculates a start-up fuel injection pulse width TIST on the basis of a cooling water temperature Tw, an engine rotation speed Ne, and a fuel supply pressure Pf to a fuel injector (8) (S1). When the fuel supply pressure Pf exceeds a required fuel pressure, the engine controller (21) executes stratified combustion by means of compression stroke fuel injection. By setting the required fuel pressure precisely in accordance with a start-up condition defined by the start-up fuel injection pulse width TIST and the engine rotation speed Ne, the opportunities for stratified combustion during start-up increase, and the amount of hydrocarbon discharge decreases.

    摘要： A direct fuel injection/spark ignition engine control device is configured to enable compression stroke injection when the fuel pressure is low at startup and immediately after startup, and to reduce the wall flow and amount of HC exhaust. When the catalyst requires warming, fuel is injected in the compression stroke, and the fuel injection timing in the compression stroke is set in accordance with the fuel pressure. When the fuel pressure is low, the fuel injection timing injects fuel in the first half of the compression stroke. The fuel injection timing is delayed as the fuel pressure increases until the optimum fuel injection timing is reached.
