Abstract
A multi-cylinder engine includes first and second subsets of cylinders. A dedicated-cylinder exhaust gas recirculation (EGR) system is associated with the second subset of cylinders. A plasma ignition system is disposed in the second subset of cylinders. A controller operates the plasma ignition system to control the plasma igniters to execute plasma discharges in the second subset of cylinders to generate residual exhaust gas, which is recirculated through the dedicated-cylinder EGR system to the intake air system for introduction into intake air.
