A disclosed method of automatically stopping and restarting a vehicle engine determines if one or more stop/start enablement condition has been met. If the stop/start enablement condition or conditions have been met, the method initiates an engine shutdown. If a restart request is made before the engine reaches a predetermined threshold speed, then a first restart sequence is initiated. If a restart request is made when the engine speed is less than the predetermined threshold speed but still greater than 0, then a second restart sequence is initiated.

A starting device for a combustion engine includes a housing relative to which a rope pulley, a spring housing and an entrainer can rotate about a rotation axis. A coupling unit produces a rotationally-fixed connection between the rope pulley and the spring housing in response to a rotational movement of the rope pulley in a starting direction. The spring housing has a spring receiving space for a tension spring and is connected to an entrainer by the spring. The coupling unit has a first coupling element and a second coupling element, which interact at a contact location which is at a spacing (d) to the rotation axis and is at least as large as the maximum spacing (c) of the tension spring to the rotation axis.

A startup assistance device, which assists startup of an internal combustion engine in which fuel is supplied from an electronically controlled fuel injection device and ignition is performed by an ignition device, includes a recoil starter which is driven by manpower and which performs cranking for starting up the internal combustion engine, an electric rotary machine which adds torque to a crankshaft of the internal combustion engine during at least one of a startup period of the internal combustion engine using the recoil starter and a standby period before the startup period, a power source unit which supplies power to the electric rotary machine, and a control unit which controls the magnitude and time of the torque output by the electric rotary machine.

A control system of a vehicle includes: an electric motor configured to phase rotation of an camshaft of an engine relative to rotation of a crankshaft of the engine; a current module configured to, while the engine is off: selectively transition a current signal back and forth between a first state and a second state; and a motor driver module configured to, while the engine is off: apply power to the electric motor from a battery and adjust a position of the camshaft toward a predetermined position when the current signal is in the first state; and disconnect the electric motor from the battery and allow the position of the camshaft to move away from the predetermined position when the current signal is in the second state.

A method of stopping an engine crankshaft includes selecting a target angular position at which the engine crankshaft is to be stopped and detecting an actual angular position of the engine crankshaft and a rotational speed of the engine crankshaft. A stopping torque in calculated based on the actual angular position of the engine crankshaft and the rotational speed of the engine crankshaft. The stopping torque is applied to the engine crankshaft via a motor/generator operably connected to the engine crankshaft. The engine crankshaft is stopped at the target angular position via the application of the stopping torque.

Methods and systems are provided for operating a split exhaust engine system that provides blowthrough air and exhaust gas recirculation to an intake passage via a first exhaust manifold and exhaust gas to an exhaust passage via a second exhaust manifold. In one example, the engine system may be installed in a hybrid vehicle, and, in response to a request to restart the engine while the vehicle is being propelled via motor torque only, the engine may be rotated unfueled via the motor torque at less than cranking speed while at least partially opening a valve disposed in a passage coupled between the first exhaust manifold and the intake passage. In another example, in response to the request to restart the engine, all exhaust valves of a second set of exhaust valves coupled to the second exhaust manifold may be deactivated.
