Abstract
A system, method, and engine control module for energy ignition management of a combustion engine. The method may be performed by the system or the engine control module. The method includes determining operating conditions of the combustion engine, setting ignition energy characteristics for a dedicated EGR cylinder and a non-dedicated EGR cylinder based on the operating conditions. The ignition energy characteristics include at least one of magnitude of energy, current, voltage, and ignition energy duration. At least one characteristic of the ignition energy characteristics for the non-dedicated EGR cylinder is different than a corresponding characteristic for the dedicated EGR cylinder. The method also includes energizing ignition aid plugs based on the ignition energy characteristics.
