Abstract:
A piston crown for a piston of an internal combustion engine, the piston crown extending in an axial direction along a central axis and in a radial direction outwardly from the central axis. The piston crown comprises an annular surface at a first end of the piston crown in the axial direction; and a piston bowl located radially within the annular surface and recessed relative to the first end of the piston crown. The piston bowl comprises a raised floor in a radially central region of the piston bowl; an arcuate surface located radially outward relative to the raised floor; and a lip chamfer surface extending radially outwardly from the arcuate surface and radially inwardly from the annular surface. A radially inmost portion of the lip chamfer surface is radially inside the radially outermost portion of the arcuate surface. A bowl maximum radius, R max , is defined as a distance in the radial direction between the central axis of the piston crown and an innermost edge of the annular surface. A bowl height, H, is defined as a distance in the axial direction between the annular surface and a surface of the piston bowl furthest from the annular surface. A lip re-entrancy angle is defined as an acute angle between a line extending in the radial direction at the first end of the piston crown and a tangent to the arcuate surface closest to the first end of the piston crown. The bowl maximum radius, R max , is between 2.3 and 3.2 times the bowl height, H, and the lip re-entrancy angle is between 40° and 80°.
