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°.

Claim (Index 9):
The piston crown of  claim 8  wherein the bowl throat radius, R1, is between 0.65 and 0.72 times the radial length, preferably between 0.66 and 0.71 times, even more preferably between 0.67 and 0.70 times, and still further more preferably between 0.68 and 0.69 times.
