Piston blank for a forged piston |
摘要 |
A forged piston blank for a forged piston of an internal combustion engine is formed with undercuts between the eye portions and crown side or head portions of the ears so that a larger piston pin may be accommodated by virtue of the fact that the wall thickness at the upper portion of the eye is greater than the wall thickness of the head portion of the ear. |
