摘要： An internal combustion engine includes a piston disposed within a bore and moveable in a reciprocating motion within the bore along a central bore axis. The piston includes an axial end surface that defines a combustion chamber having a plurality of annular recesses recessed into the axial end surface of the piston. One of a plurality of valves is disposed opposite each of the plurality of annular recesses of the combustion chamber. Each of the plurality of annular recesses is axially aligned with a head of one of the plurality of valves and is sized to receive an outer perimeter of the head therein to provide clearance during valve overlap, between the axial end surface of the piston and the head of the valve, when the piston is disposed near a top dead center position.
