Abstract: In response to a restarting request generated during a stopping period, in which fuel injection is stopped to automatically stop engine operation, either starter starting or combustion starting is selected. In the starter starting, the engine is restarted using a starter motor. In the combustion starting, the engine is restarted through fuel injection and ignition without using the starter motor. If the rotational resistance acting on the crankshaft is determined to be of such a magnitude that the combustion starting is impossible, the starter starting is carried out in response to the restarting request generated during the stopping period.

Abstract: A first circulation channel connects a first heat demand part and first supply heat exchanger with its forward route and return route. Supply and discharge channels are connected to a first heat accumulation tank, which accommodates a second heat medium heated in the first supply heat exchanger and supplied via the supply channel. A heat accumulation switching valve changes over communication of the second heat medium serving as hot heat or cold heat flowing from the first supply heat exchanger and supplied to the first heat demand part without branching to the supply channel or branching to the supply channel and supplied to the first heat accumulation tank. A heat-accumulating hot-water-supplying air conditioner operates at a first temperature when the second heat medium from the first supply heat exchanger branches to the supply channel, and at a second lower temperature when the second heat medium does not branch to the supply channel.

Abstract: When a stop position of a piston resulting from the automatic stop is in a range that is on an advance side of a threshold in terms of crank angle, fuel injection is performed at beginning of the automatic restart-up in the cylinder that is in the intake stroke and an ignition is performed in a subsequent initial compression stroke in the same cylinder. When the stop position of the piston resulting is in a range that is on a retard side of the threshold in terms of crank angle, initial fuel injection is performed in the cylinder that next enters an intake stroke among the cylinders of the internal combustion engine after the beginning of automatic restart-up and initial ignition is performed in a subsequent compression stroke in the same cylinder. The threshold is determined in accordance with an amount of deviation of a crank angle.
