Abstract

In at least one aspect of this disclosure, a method of controlling compression ignition in a compression ignition (CI) combustion system can include introducing a combustion primer (CP) and oxygen into a cylinder of the CI combustion system before and/or during a compression cycle, introducing a pilot charge of primary fuel reactant (PFR) into the cylinder before and/or during the compression cycle, allowing the pilot charge of PFR to combust at and/or before top dead center (TDC) of the cylinder to form combusted PFR (C-PFR), and combining a main charge of PFR with the CP, the C-PFR, and the oxygen to cause the main charge of PFR to instantaneously and/or homogeneously burn upon introduction into the cylinder due to the generation of radicals by the CP and C-PFR.
