Systems, apparatus, and methods for inducing enhanced radical ignition in internal combustion engines using a radical chemicals generator

An apparatus, comprising:

• a housing defining a radical chemicals generator volume (RCGv);
• a fuel delivery control device coupled to a passageway extending into the RCGv, the fuel delivery control device configured to control delivery of a portion of fuel into the RCGv via the passageway;
• a spark device configured to ignite a mixture of air and the portion of fuel in the RCGv to generate a flame that produces combustion intermediates and combustion products;
• and
• a quenching system (QS) coupled to a head of an engine, the QS including a plurality of orifices, the plurality of orifices having a predetermined length-to-diameter ratio of at least three such that the plurality of orifices is configured to quench the flame to produce a jet of partial combustion products containing radical species (RS),
• the plurality of orifices further configured to inject the jet of partial combustion products into a main combustion chamber (MCC) of the engine containing a fuel-air charge to induce ignition of the fuel-air charge.
