The starter motor includes an overlapping portion that overlaps with the clutch, as the vehicle is seen from the side, and a front portion located forward of a center axis of a main shaft, as the vehicle is seen from the side.

A method of controlled stopping an internal combustion engine having a stop-start mode and starter assembly includes detecting when the stop-start mode is active. The method also includes monitoring current rotational speed and position of the engine. The method additionally includes determining when the current rotational position is within a predetermined range of a target stop rotational position and the current rotational speed is less than a threshold rotational speed, and afterward energizing the starter assembly to engage the engine. The method also includes establishing a time delay following energizing the starter assembly to confirm engagement of the starter assembly with the engine. Furthermore, the method includes applying a torque by the starter assembly to stop the engine at the target stop position. A vehicle powertrain employing the engine equipped with the stop-start mode, the starter assembly, and an electronic controller configured to execute the method is also provided.

An internal combustion engine includes an engine block, a crankshaft configured to rotate about a crankshaft axis, a flywheel coupled to the crankshaft and positioned above the engine block, an outer housing positioned above the engine block and the flywheel, and an electric starting system. The electric starting system includes an electric motor and an energy storage device positioned above the flywheel and below the outer housing. The energy storage device is electrically coupled to the electric motor to power the electric motor. When the electric starting system is configured to rotate the crankshaft to start the engine when the electric starting system is activated.
