ABSTRACT:
The starting system for an internal combustion engine includes a crankshaft and a camshaft sprocket which form the carrier for a planet pinion set whose elements are continuously engaged with a sun gear mounted and a ring gear mounted by a one-way brake to the engine block. A starting motor is connected by an endless chain or belt to a sprocket connected by a one-way driving connection to the sun gear. An accessory drive pulley and the rotor of the engine oil pump are continuously and directly connected to the sun gear. A hydraulic piston, actuated by engine oil pressure, selectively breaks the ring gear when engine speed is below a predetermined value provided engine oil pressure is at least equal to a predetermined pressure and releases the ring gear when engine speed exceeds the predetermined speed.
