Engine Piston |
| 摘要 |
A piston for an internal combustion engine includes a piston body forming a crown portion and a skirt portion. The skirt portion includes a bore that is arranged to receive a pin for connecting the piston to a connecting rod. The crown portion forms a bowl surrounded by a flat crown surface having an annular shape. The bowl and flat crown surface meet along a circular edge surrounding a rim of the bowl. The piston further includes an annular protrusion disposed within the bowl adjacent the rim. The annular protrusion has a generally convex shape in cross section that is created by an upper, inwardly extending surface and a lower, inwardly extending surface, which meet along a convex apex. |
