    摘要： A method of controlling an engine-operating-characteristic changing device operable between a first and a second operating state and including a locking device for locking the changing device in the first operating state in which a compression ratio of an intake air of an internal combustion engine is maintained at a value higher than that in the second operating state, the method including steps of determining whether there is a possibility that the engine-operating-characteristic changing device is locked in the first operating state by the locking device, where the changing device should not be placed in the first operating state, and if it is determined that there is the possibility, implementing a preventive operation to prevent the locking unit from locking the changing device in the first operating state.

    摘要： The start control procedure of the invention lags an open-close timing VVT of an intake valve, restricts a throttle opening TH of a throttle valve, and starts cranking an engine with a lower torque Tlow. When a pressure Pf of a fuel supplied to in-cylinder fuel injection valves reaches or exceeds a preset reference value, which is greater than a sum of an in-cylinder compression pressure Pin and a closed valve position-retaining pressure Pcv of the in-cylinder fuel injection valves, the start control procedure cranks the engine with a standard cranking torque Tset. The start control procedure then starts advance of the open-close timing VVT of the intake valve, cancels the restriction of the throttle opening TH, and starts fuel injection from the in-cylinder fuel injection valves. This arrangement enables the fuel pressure Pf to quickly rise to or above the sum of the in-cylinder compression pressure Pin and the closed valve position-retaining pressure Pcv, and thereby effectively prevents the in-cylinder fuel injection valves from being inadequately opened.

    摘要： A control device for a hybrid vehicle causes the hybrid vehicle to travel in limp-home mode with motive power from an engine when either a motor or a battery for travel cannot be used. The engine incorporated in the hybrid vehicle includes an EGR device for recirculating part of exhaust gas to an intake system of the engine again. Even if an operation state of the engine satisfies a prescribed EGR permission condition for operating the EGR device, during the travel in limp-home mode with an abnormality detection flag being set to 1, the control device prohibits operation of the EGR device.
