Abstract
An internal combustion engine that includes a cylinder block formed with a cylinder bore, a cylinder head operatively connected to the cylinder block; a piston slidably disposed in the cylinder bore to define a combustion chamber; an engine front side squish area and a rear side squish area where the engine front and rear side squish areas include narrow gaps formed between a cylinder head and the piston is disclosed. The engine front side squish area and the engine rear side squish area generate a squish flow in the combustion chamber in response to the piston moving within the cylinder bore. Engine front and rear side igniter plugs are also provided that each include a pair of electrodes placed adjacent the respective engine front and rear side squish areas so that squish flow may pass through an igniter gap defined between the pairs of electrodes of the front and rear side igniter plugs.
