VARIABLE IGNITION ENERGY MANAGEMENT

摘要

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.

1. A method for ignition energy management, the method comprising:
determining operating conditions of a combustion engine including at least one dedicated exhaust gas recirculation (EGR) cylinder, a non-dedicated EGR cylinder, and ignition aid plugs configured to aid ignition in the at least one dedicated EGR cylinder and the non-dedicated EGR cylinder; setting ignition energy characteristics for the dedicated EGR cylinder and for the non-dedicated EGR cylinder based on the operating conditions, the ignition energy characteristics including at least one of magnitude of energy, current, voltage, waveform shape, and ignition energy duration, and excluding ignition timing, at least one characteristic of the ignition energy characteristics for the non-dedicated EGR cylinder being different than a corresponding characteristic for the dedicated EGR cylinder; and energizing the ignition aid plugs based on the ignition energy characteristics.
