Abstract

A system (40) for starting an internal combustion engine (12) of an automotive vehicle (10) has a controller (54) coupled to a starter/alternator (42). The engine (12) has a crankshaft (50) and a turbocharger (24). The controller (54) initiates the starting of the engine (12) by rotating the crankshaft (50). The rotating crankshaft (50) displaces an amount of air from the cylinders (14) of the engine (12) to rotate the rotor shaft of the turbocharger (21). The turbocharger (25) thus draws in air, compresses the air and provides the compressed air to the cylinders (14). When the engine is started the initial power is increased due to the compressed air.
