Abstract
Exemplary power cell assemblies and methods of making the same are disclosed. An exemplary power cell assembly may include a piston crown and connecting rod. In an exemplary illustration, a power cell assembly includes a piston crown having a ringland extending circumferentially about a combustion bowl. The boss portions may each include inwardly extending shoulders defining arcuate crown running surfaces. The power cell assembly may further include a connecting rod having a shank and an upper end received in a cavity of the crown. The upper end of the connecting rod may define arcuate connecting rod running surfaces extending away from the shank. The crown running surfaces and connecting rod running surfaces generally allow the connecting rod to pivot with respect to the piston crown about an axis of rotation that extends from one of the boss portions to the other of the boss portions.
