ABSTRACT:
The lip of the combustion bowl of a piston for an internal combustion engine has different radii in different sections of the bowl. Most of the lip is sharp to reduce emissions. The part of the lip above the piston pin bore is less sharp to reduce the mechanical stresses that otherwise would accumulate there in a sharp lip, cracking the piston. The lip has a smooth transition between the two radii to avoid creating additional stress.
