ABSTRACT:
An internal combustion engine includes one or more pistons (3) connected to a common crankshaft (4), a balancer shaft (10) connected to the crankshaft (4) to be rotated thereby at the same speed as the crankshaft (4) but in the opposite sense, the balancer shaft (10) carrying mutually offset eccentric weights (14) at its ends and an integrated starter generator unit (26) including a stator (27) and a rotor (23). The rotor (23) is mounted to rotate about the axis of the balancer shaft (10) and is connected to the balancer shaft (10) by step up gearing (18, 20, 22) such that the rotor (23) rotates in the same sense as the balancer shaft (10) but at a substantially greater speed.
