Summary:The application discloses a method and system for a spark ignition engine. The method for a spark ignition internal combustion engine comprises energising a common ignition coil (10, 20) to simultaneously actuate a first spark plug (11) coupled to a first cylinder and a second spark plug (12) coupled to a second cylinder, for specific ignition coil energization, the spark event in only one of the cylinders initiating combustion with the spark event in the other cylinder being wasted; and selectively delaying an intake valve opening and/or fuel injection for the other cylinder so as to prevent backfire into an intake manifold of the engine.
