摘要： The present invention relates to an apparatus for and a method of controlling a variable valve timing mechanism. The valve timing mechanism changes over between a first cam for which the closing timing IVC of the intake valve is after intake bottom dead center, and a second cam for which the closing timing IVC is closer to intake bottom dead center than the closing timing IVC with the first cam. Here at the time of stopping the internal combustion engine, the valve timing mechanism changes over to the first cam, and the initial intake stroke performs operation at low effective compression ratio. In the second and subsequent intake strokes, the valve timing mechanism changes from the first cam to the second cam.

摘要： A piston for an internal combustion engine is provided. The engine has an intake port through which an intake air is introduced into the cylinder in a way as to produce a swirl that travels along while whirling about an axis transversal to an axis of the cylinder. The piston has at a crown face thereof a cavity that has a part-cylindrical bottom. The cavity has a longitudinal center axis extending obliquely to a crank axis so that the longitudinal center axis of the cavity nearly coincides with an axis along which the swirl travels within the cylinder.

摘要： In a control apparatus for and a control method of controlling a variable valve mechanism in a hybrid vehicle, just before an engine is stopped in response to an automatic stop request, an intake valve closing timing is controlled to be set to a second closing timing near the bottom dead center to stabilize an engine stop position; when the engine is stopped, the intake valve closing timing is retarded from the second closing timing to a first closing timing that is suitable for engine start; the engine is started with the closing timing being set to the first closing timing, and the intake valve closing timing is changed towards the retard angle side beyond closing timing against rev-up of the engine just after completion of engine start, so that the rev-up can be suppressed with good response while controlling the intake valve closing timing as required for starting the engine.
