Embodiment Construction
[0021] The following description relates to systems and methods for operating an engine with multiplexed pre-chamber and main chamber ignition systems. Each cylinder of the engine may have a cylinder configuration that includes a main chamber spark plug directly coupled to the cylinder and an active prechamber that includes a fuel injector, a prechamber spark plug, and an air injector, such as figure 1 shown. Additionally, the ignition system may be configured such that the first ignition coil provides voltage to both the pre-chamber spark plug of the first cylinder and the pre-chamber spark plug of the second cylinder, while the second ignition coil supplies voltage to the main combustion chamber of the first cylinder. Both the spark plug and the main combustion chamber spark plug of the second cylinder provide voltage as figure 2 shown. To improve engine performance, the image 3 A method of operating an ignition system having multiplexed ignition coils to provide precha...
