Abstract
A piston of an internal combustion engine is provided and includes a piston skirt enclosing at least a portion of an underside of a piston crown. A cooling oil passageway is provided on the underside of the piston and extends from a first part to a second part of the underside, where the first part is closer than the second part to a fluid flow from a cooling oil source. The cooling oil passageway may include a main channel and a branch channel extending from the main channel at an angle.
Claims20
An engine comprising:
- a piston comprising a piston crown and an opposed underside encircled by a piston skirt, a cooling oil guide positioned on and extending between first and second parts of the underside;
- and
- a cooling oil source providing a jet of cooling oil to a first part of the underside;
- wherein the guide is shaped to direct oil of the jet from the first part to the second part of the underside.
1 more element
A piston for an engine, comprising:
- a body comprising a piston crown and an underside opposed thereto, a piston skirt provided about a perimeter of the underside;
- and
- a cooling oil guide formed on and extending from a first part to a second part of the underside to direct cooling oil flow from the first part to the second part, the first and second parts spaced apart by a pin bore of the underside.
A method comprising:
- forming a piston for an engine with a crown, an opposed underside with a pin bore separating first and second parts of the underside, and a skirt encircling the underside;
- and
- forming a cooling oil guide on the underside, the guide extending from the first part to the second part to direct cooling oil from the first part to the second part.
