Abstract
A method for igniting a motor vehicle combustion engine is implemented by an electronic control unit of an ignition circuit of a motor vehicle combustion engine, the ignition circuit including a transformer, including a primary coil and a secondary coil, and a spark plug electronically connected to the secondary coil of the transformer, the primary coil being capable of charging, and capable of discharging into the secondary coil, the discharge duration of the primary coil being predefined, the spark plug being capable of generating a spark during the discharging of the primary coil into the secondary coil, the method including: a) a step of requesting to start a combustion cycle of the engine; a first phase referred to as 'generating a main spark'; and c) a second phase referred to as “generating at least one subsidiary spark”.
