US Patent 7131413 Start control apparatus of internal combustion engine

A start control apparatus of an internal combustion engine comprises an ignition device for igniting an air-fuel mixture in a combustion chamber of the internal combustion engine, a start demanding device for demanding a start of the internal combustion engine, a starting device for starting the internal combustion engine, a determining device for determining a possibility of a self-ignition of the internal combustion engine at a time when a start demand is issued from the start demanding device, and a start procedure control device for igniting the air-fuel mixture in the combustion chamber by the ignition device after the start demand from the start demanding device in the case where the determining device determines that the possibility of the self-ignition of the internal combustion engine is higher than a predetermined level, thereafter starting the internal combustion engine by the starting device.
