Abstract

A method and a system for operating an electric turning machine (ETM) operatively connected to an internal combustion engine (ICE) are disclosed. The ETM operates as a motor with a first control strategy and as a generator with a second control strategy, the second control strategy being distinct from the first control strategy. The system comprises an engine control unit adapted for controlling an operation of the ETM according to the first and second control strategies. Electric and assisted start procedures are available for starting the ICE by delivering electric power from a power source to the ETM which is co-axially mounted to a crankshaft of the ICE. Assisted start includes delivering the electric power to the ETM while a recoil starter is used to rotate the crankshaft. A manual start procedure is also available. The power source is charged by the ETM when the ICE is running.
