Abstract
Methods and systems are provided for adjusting multiplexed ignition signals in an engine system based on engine operating conditions, each cylinder of the engine system including a main chamber spark plug and a pre-chamber system. In one example, a method may include multiplexing spark signals to a first spark plug, a second spark plug, a third spark plug, and a fourth spark plug, the first spark plug coupled to a pre-chamber of a first cylinder, the second spark plug coupled to a pre-chamber of a second cylinder, the third spark plug coupled to a main chamber of the first cylinder, and the fourth spark plug coupled to the main chamber of the second cylinder. In this way, one ignition coil may be used to actuate two different spark plugs coupled to separate cylinders.
