摘要： 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.

摘要： A stop and start control device for an internal combustion engine is configured to perform an automatic stop control for stopping combustion in the internal combustion engine while a vehicle is travelling. The stop start control device is configured to initiate a restart operation during vehicle travel when a restart request generates before the vehicle stops in a state in which the combustion in the internal combustion engine has been stopped by the automatic stop control. The restart operation during vehicle travel is a restart operation for the internal combustion engine while the vehicle is travelling. The stop and start control device is configured to set an ignition timing of a first ignition in the restart operation during vehicle travel to an ignition timing advanced from an ignition timing of a second ignition in the restart operation during vehicle travel.

摘要： A start control system for an engine is provided. The engine is a direct injection engine, and the engine is provided with a starter motor. The start control system includes an electronic control unit. The electronic control unit is configured to execute fuel injection and ignition in a cylinder in an expansion stroke so as to start the engine without using the starter motor, when the electronic control unit determines that a restart condition of the engine is satisfied immediately before the engine is stopped. The electronic control unit is configured to control an ignition delay time based on at least one of a rotational direction and a rotational speed of a crankshaft, during execution of the fuel injection. The ignition delay time is a period of time from fuel injection into the cylinder in the expansion stroke to ignition.
