Abstract
A method of controlling an internal combustion engine during a start up phase, include cranking the internal combustion engine to initiate the start up phase and controlling an alternator load so as to increase load on the engine during at least a part of the start up phase, thereby to control engine speed flare and/or at least partially to recover energy used to start the internal combustion engine. Even when base ignition timing and/or fueling calibration for starting the engine is modified to improve combustion stability, the alternator load can be controlled to control engine speed flare and/or recover start energy.
