Abstract:
A piston for an internal combustion engine includes a piston crown having a combustion bowl formed therein, a piston rim extending circumferentially around the combustion bowl and a heat-dissipating chamfer between the combustion bowl and the piston rim. The chamfer is structured by way of at least one of size, angle, or material thickness to an oil gallery to balance heat dissipation with combustion properties. Related methodology is disclosed.
