    摘要: Disclosed herein is a control apparatus for a spark-ignition engine that is capable of avoiding knocking at the time of high-load operation. With this control apparatus, a residual-gas suction unit or the like is not used, an exhaust gas does not deteriorate due to injection in a compression stroke, and a thermal efficiency also does not decrease. An engine control apparatus (ECU) 20 is used for the control of a direct-injection type spark-ignition engine. During the high-load operation of the spark-ignition engine, the ECU 20 injects fuel a plurality of times. In addition, the ECU performs first fuel injection toward internal EGR that exists in a combustion chamber of the spark-ignition engine.

    摘要: In a homogeneous charge compression-ignited internal-combustion engine, based on information regarding the operational state of the engine, a combustion mode switching discriminator selects a homogeneous charge compression-ignited combustion mode if engine operating conditions allow homogeneous charge compression-ignited combustion. If not, the combustion mode switching discriminator selects a spark-ignited combustion mode. Immediately after switching from spark-ignited combustion to homogeneous charge compression-ignited combustion, a combustion mode switching corrector outputs switching correction values for operating quantities for homogeneous charge compression-ignited combustion. The correction values are used to adjust the operating quantities for homogeneous charge compression-ignited combustion, and new operating quantities obtained from the adjustments are output as control quantities from a combustion mode selector.

    摘要: An engine controller capable of reducing torque fluctuation and the like in change between spark ignition combustion and homogeneous charge compression ignition combustion is provided. Spark ignition burning mode or homogeneous charge compression ignition burning mode is selectively set as burning mode according to the operating state of an engine. In spark ignition burning mode, a spark plug is used. In homogeneous charge compression ignition burning mode, fuel is burned utilizing pressure rise in a combustion chamber in conjunction with the ascent of a piston. The burning mode is changed between these modes. In transition for change between the spark ignition burning mode and the homogeneous charge compression ignition burning mode, the following measure is taken: a period during which the lift amount and/or the valve opening period (IVevent) of an intake valve is made smaller than a set value for the homogeneous charge compression ignition burning mode is provided.
