INTERNAL COMBUSTION ENGINE COMPRISING AN ELECTRIC DRIVE ON THE CRANKSHAFT

摘要

An internal combustion engine includes a crankshaft situated in a crankcase and having at least two crank journals, each mounted in a main bearing of the crankcase such that the crankshaft is rotatable about a rotational axis. The crankshaft has at least one crank pin running coaxially with the rotational axis and positioned eccentrically in relation to the axis. The pin is connected to the crank journals by crank webs and is connected to a number of pistons by a number of connecting rods. The respective pistons oscillate in a number of cylinders between a top dead centre and a bottom dead centre. The rotor of an electric machine is located on the crank webs. The stator of the electric machine is located on the crankcase. The stator of the electric machine interacts electromagnetically with the rotor and is connected to a converter unit to transmit electric energy bi-directionally.
