Abstract:
1. A method for controlling a reduction in required heat and required fuel concentrations relative to oxygen concentrations for an ignition of a fuel within a main combustion chamber of an engine, the method comprising: providing a plurality of radical ignition species, the plurality of radical ignition species generated in at least one prior combustion cycle in at least one secondary chamber associated with the main combustion chamber of the engine, wherein the plurality of radical ignition species is generated by at least one OH-radical ignition species driven chemical kinetic mechanism; directing a portion of the plurality of radical ignition species to the main combustion chamber; regulating an accumulation of the portion of the radical ignition species and a generated radical ignition species of the main combustion chamber to modulate an ignition event for fuel in the main combustion chamber.
