Abstract
An apparatus including motor/generator whose axis is spaced from and parallel to engine crankshaft, 3-elements type input and output mechanism disposed coaxially with the motor/generator and having first rotary element connected to the crankshaft, second rotary element connected to output shaft of the motor/generator, and third rotary element, and first and second one-way clutches associated with the input and output mechanism, which is arranged such that speed V1 of forward rotation of the first rotary element by engine is reduced when the second rotary element is rotated forward with the third rotary element held stationary. The motor/generator is operated to rotate the second rotary element to start the engine, with the first one-way clutch inhibiting the reverse rotation of the third rotary element, and as an electric generator, with the first one-way clutch allowing the forward rotation of the third rotary element while the three rotary elements are rotated as a unit under an action of the second one-way clutch.
