    摘要： This invention relates to a control system and method for an in-cylinder injection internal combustion engine, which perform control of the timing of fuel injection, the timing of ignition and an EGR rate to assure the stability of combustion in the engine and also its exhaust gas cleaning performance while promoting an improvement in gas mileage by performing injection in compression strokes. The system is provided with a fuel injection valve for directly injecting fuel into a combustion chamber, a spark plug arranged in the combustion chamber, an EGR valve arranged in an EGR passage, a fuel injection timing control unit for controlling a fuel injection timing of the fuel injection valve on a basis of a preset target fuel injection timing, an ignition timing control unit for controlling an ignition timing of the spark plug on a basis of a preset target ignition timing, an exhaust gas recirculation rate control unit for controlling an opening of the EGR valve on a basis of a preset target EGR rate, and a misfire determination unit for detecting a burning fluctuation, whereby upon detection of a burning fluctuation, the target fuel injection timing, the target ignition timing and the target EGR rate are retarded or decreased.

    摘要： An internal combustion engine includes a cylinder head having a pair of upright intake ports formed therein on opposite sides of a plug hole extending along a cylinder axis, and each intake port has an upstream-side upright part extending from the top face of the cylinder head along the cylinder axis and a downstream-side slanting part having an intake opening communicating with a combustion chamber on one side of an imaginary plane containing the cylinder axis. An upper opening of each intake port opening in the top face of the cylinder head has a peripheral edge extending along the peripheral edge of an upper opening of the plug hole, and the peripheral edge of the upstream-side upright part extends along the outer surface of a lash adjuster. When viewed in vertical section along the imaginary plane, the upstream-side upright part extends obliquely downward from the top face of the cylinder head in a direction away from the lash adjuster, and the downstream-side slanting part approaches the plug hole with decrease in distance to the combustion chamber and then extends parallel to the plug hole. The downstream-side slanting part, when viewed in vertical section perpendicular to the imaginary plane, extends away from the cylinder axis with decrease in distance to the intake opening. With the intake ports having the above overall shape and sectional shape, each intake port can be given a required cross-sectional area without increasing the dimensions of the engine, and makes it possible to form a proper intake air flow inside the combustion chamber.

    摘要： This invention relates to an in-cylinder injection internal combustion engine. A recessed portion (22A) is arranged in a top wall of a piston (22) to promote formation of a vertical swirl so that a flow of inducted air introduced into a combustion chamber (27) of the engine is caused to advance from a lower wall (21A) of a cylinder head (21) of the engine toward the top wall of the piston (22) and then to advance backward from the top wall of the piston (22) toward the lower wall (21A) of the cylinder head (21). A corner of the recessed portion (22A) is formed blunter at an outlet side of the vertical swirl than at an inlet side of the vertical swirl. In the in-cylinder injection internal combustion engine in which fuel is injected directly into the combustion chamber (27), it is possible to achieve inter alia a high gas mileage by allowing a lean air-fuel mixture to undergo stratified combustion and also a high power output when a gas-fuel mixture richer than the lean air-fuel mixture is burnt. A high-efficiency internal combustion engine can hence be provided.
