Abstract
A connecting rod for an internal combustion engine may include a connecting rod shank, a large connecting rod eye, and a small connecting rod eye with a pin bore. An end face of the small connecting rod eye may also include at least one overhang, the overhang running parallel to a central axis of the pin bore over its entire width transverse to the central axis of the pin bore. An edge of the overhang may also run parallel to the central axis of the pin bore.
Claims16
A connecting rod for an internal combustion engine, comprising:
- a connecting rod shank;
- a large connecting rod eye;
- and
- a small connecting rod eye with a pin bore;
- wherein an end face of the small connecting rod eye has at least one overhang running parallel to a central axis of the pin bore over an entire width of the pin bore transverse to the central axis of the pin bore;
- wherein an edge of the at least one overhang runs parallel to the central axis of the pin bore;
- and
- wherein the end face of the small connecting rod eye has a recess running transverse to the central axis of the pin bore and arranged one of symmetrically and asymmetrically to the central axis of the pin bore.
An assembly for an internal combustion chamber, comprising:
- a piston including a piston shaft with hub bores;
- a connecting rod including a connecting rod shank, a large connecting rod eye and a small connecting rod eye with a pin bore;
- and
- an injection nozzle;
- wherein the small connecting rod eye is mounted by a piston bolt accommodated in the hub bores and the pin bore in a piston interior of the piston;
- and
- wherein an end face of the small connecting rod eye has at least one overhang running parallel to a central axis of the pin bore at least on its side facing the injection nozzle over an entire width of the pin bore transverse to the central axis of the pin bore;
- and
- wherein an edge of the at least one overhang runs parallel to the central axis of the pin bore.
A connecting rod for an internal combustion engine, comprising:
- a connecting rod shank;
- a large connecting rod eye;
- and
- a small connecting rod eye with a pin bore;
- wherein an end face of the small connecting rod eye has two opposite overhangs running parallel to a central axis of the pin bore over its entire width transverse to the central axis of the pin bore;
- wherein an edge of the overhangs runs parallel to the central axis of the pin bore;
- wherein the small connecting rod eye has at least one concave curvature running directly below an edge parallel to the central axis of the pin bore over an entire width of the piston bore;
- and
- wherein one of:
- the end face of the small connecting rod eye has a tub-shaped recess and a bore formed within the tub-shaped recess;
- and
- the end face of the small connecting rod eye has a recess running transverse to the central axis of the pin bore and arranged one of symmetrically and asymmetrically to the central axis of the pin bore.
