Abstract:
1. An internal combustion engine system comprising: a combustion chamber defining a variable volume, the combustion chamber delineated by a cylinder and a piston moving in the cylinder; an intake system directing intake air to the combustion chamber; an exhaust system directing exhaust gasses from the combustion chamber; an exhaust gas recirculation system (EGR) system for directing a portion of the exhaust gasses from the exhaust system to the intake system; a first fuel injector for introducing a first fuel charge having a first reactivity at a first time; a second fuel injector for introducing a second fuel charge having a second reactivity at a second time; a sensor monitoring an engine operating parameter; and a controller communicating with the sensor, the controller further controlling the EGR system and the second fuel injector, the controller configured to select from and adjust in a correlated manner the EGR system and the second injector in part upon the operating parameter.
