Combustion control via homogeneous combustion radical ignition (HCRI) or partial HCRI in cyclic IC engines

A combustion system for combustion of a fuel in a cyclic internal combustion engine, the combustion system comprising:

• at least one combustion chamber that receives the fuel and air for said combustion;
• means for providing the fuel to said combustion chamber;
• at least one work-power producing component that moves responsive to said combustion;
• means for generating radical ignition species, said generating starting in and continuing from a prior combustion cycle;
• and
• at least one regulator that selectively modulates a portion of said radical ignition species for said combustion in a later combustion cycle occurring after said prior combustion cycle.

A process for combustion of a fuel in at least one combustion chamber of a cyclic internal combustion engine, the process comprising:

• inserting said fuel and air into said at least one combustion chamber;
• generating radical ignition species of said fuel, said generating starting in and continuing from a prior combustion cycle;
• regulating at least one portion of said radical ignition species;
• and
• selectively modulating ignition of said fuel in said combustion chamber during a later combustion cycle than said prior combustion cycle using at least some of said at least one portion.
