Abstract
This invention is a fuel engine piston with installed bearings and belongs to the field of automotive engine components, specifically relating to a piston for a fuel engine. It includes a piston body, outer arc bearings, pin shaft bolts and sealing rings. It provides a piston for a fuel engine with bearings. The bearings on the piston enable rolling friction during piston operation, replacing sliding friction. This reduces the friction between the piston and the engine cylinder liner, decreases the energy consumption required to overcome friction, and reduces wear on the piston caused by sliding friction.
Claims3
A piston for a fuel engine with installed bearings, comprising:
- a piston body equipped with outer arc bearings,
- wherein said outer arc bearings are a type of rolling elements,
- wherein the piston body has installation grooves,
- wherein the installation grooves are provided with the outer arc bearings, and
- an outermost point of the outer arc bearings protrudes from an outer wall of the piston body,
- where the longitudinal axis of the outer arc bearings is perpendicular to the longitudinal axis of the piston body, and two end faces of the outer arc bearing are symmetrical with respect to the longitudinal axis of the piston body, so that a rolling direction of the outer arc bearing is parallel to the longitudinal axis of the piston body.
