Zusammenfassung:A cylinder head has a plunger receptacle and a piston has a plunger which, when the piston is reciprocating within an engine cylinder over an engine cycle range between BDC and an intermediate position spaced from both TDC and BDC, exposes the plunger receptacle to the interior of the engine cylinder, but which, when the piston is reciprocating over an engine cycle range between the intermediate position and TDC position, closes the plunger receptacle to the interior of the engine cylinder. A fuel/air charge is created within the engine cylinder, compressed to higher compression ratio in the plunger receptacle at TDC position where it is ignited and then used to ignite the lower compression ratio charge in the engine cylinder.
