    摘要： A start-up control device of a direct injection engine has a fuel injector (76) for injecting fuel into the engine; and a controller. The controller is programmed to determine the presence of a learned value for calculating on the basis thereof a fuel injection amount during start-up of the engine (10) by means of a stratified charge combustion operation; calculate the fuel injection amount on the basis of the learned value when the learned value is present, and control the fuel injector (76) to inject fuel in the compression stroke to start up the engine (10) by means of a stratified charge combustion operation; and control the fuel injector (76) to inject fuel in the intake stroke of the engine to start up the engine by means of a homogeneous combustion operation when the learned value is absent, and obtain and store the learned value during the homogeneous combustion operation of the engine.

    摘要： A control system for a direct-injection spark-ignition internal combustion engine is provided which includes a first control section for switchably controlling a combustion mode between a homogeneous combustion mode and a stratified stoichiometric combustion mode, and a second control section for advancing, at a time of switching from the homogeneous combustion mode to the stratified stoichiometric combustion mode, an ignition timing by an amount for offsetting a variation of torque simultaneously with switching of the combustion mode, gradually retarding the ignition timing after the switching of the combustion mode, and after the ignition timing has retarded a predetermined amount, retarding a compression stroke fuel injection timing in the stratified combustion mode while retarding the ignition timing further. A control method is also provided.

    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.
