    摘要: There is provided a method of starting an internal combustion engine having a combustion chamber and an intake valve which opens during an intake stroke of an engine cycle to allow air to be inducted into the combustion chamber. The method comprises cranking the internal combustion engine with advanced closing timing and a reduced lift of the intake valve without combustion of air and fuel in the combustion chamber from a stroke of the engine cycle prior to a first intake stroke of the combustion chamber since an engine start request, starting combustion of air and fuel in the combustion chamber after the first intake stroke, and retarding closing timing of said intake valve from the advanced closing timing and increasing the valve lift after the combustion is started. Accordingly, air charge in the combustion chamber may increase properly conforming to the engine speed increase caused by the combustion. Therefore, the torque derived from the combustion of the charged and fuel may increase the engine speed moderately after the beginning of the combustion.

    摘要: There is provided a method of stopping an internal combustion engine having a combustion chamber and an intake valve which opens during an intake stroke of an engine cycle to allow air to be inducted into the combustion chamber. The method comprises advancing closing timing and reducing a lift of the intake valve to reduce air charged in said combustion chamber and shutting off fuel to the combustion chamber upon a request of engine stop, maintaining a speed of the internal combustion engine within a predetermined range without supplying fuel to the combustion chamber and with the advanced closing timing and the reduced lift of the intake valve at least for one intake stroke of the combustion chamber, and decreasing the speed of the internal combustion engine with the advanced closing timing and the reduced valve lift of the intake valve from the predetermined range. Accordingly, the air in the combustion chamber can be quickly reduced so that the engine can be stopped without a substantial vibration caused by the compression of the air in the combustion chamber. Therefore, the period to keep the engine speed above the predetermined value can be made shorter so that the energy consumed for that, for example, electric power to operate an electric machine to drive the engine, can be reduced.
