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.

Internal combustion engine with electric starting system

An engine including an engine block having a cylinder defining a front of the engine, a blower housing coupled to the engine block and defining a hot half positioned adjacent the front of the engine and a cool half opposite the hot half, and an electric starter system positioned within the blower housing. The electric starting system includes a starter mount assembly coupled to the blower housing, an electric starter motor retained by the starter mount assembly and positioned in the cool half, and a battery mounted to the blower housing and positioned in the cool half. The battery is electrically coupled to the electric starter motor.

An internal combustion engine includes an engine block, a blower housing configured to direct cooling air to the engine block, an electric starting system, and a crankshaft configured to rotate about a crankshaft axis. The electric starting system includes an electric motor and an energy storage device located within the blower housing. The energy storage device is electrically coupled to the electric motor to power the electric motor, and is positioned above the crankshaft. When the starter motor is activated, the electric starting system rotates the crankshaft to rotate the engine for starting.

An internal combustion engine includes an engine block, an electric motor, a worm coupled to and rotated by the electric motor, a worm gear coupled to and configured to be rotated by the worm, a crankshaft configured to rotate about a crankshaft axis, a flywheel including a flywheel cup having flywheel protrusions, a clutch driven by the worm gear and configured to engage the one or more flywheel protrusions such that the crankshaft is rotated, and an energy storage device electrically coupled to the electric motor. The clutch is configured to disengage from the flywheel protrusions when the rotational speed of the crankshaft exceeds the rotational speed of the worm gear. When the electric motor is activated, the electric motor rotates the worm rotating the worm gear, which causes the clutch to engage the flywheel protrusions, transferring worm gear rotation to the flywheel and the crankshaft to rotate the engine for starting.
