Abstract
An internal combustion engine includes an engine block having a cylinder, a cylinder head disposed on one end of the cylinder, a piston disposed within the cylinder, and a rim. A piston crown of the piston defines a piston bowl. The rim depends from at least one of the cylinder head and piston and is located radially inward from the piston crown. At least one of the piston crown and cylinder head defines a passageway that is configured to guide a squish flow from between the piston crown and cylinder head to the piston bowl to interact with a plurality of flames within the piston bowl to enhance combustion.
