Abstract
An internal combustion engine includes a piston having a crown portion with a bottom surface and a skirt projecting therefrom to form a cavity, and a connecting rod having at one end a semicylindrical yoke portion with an upwardly directed semicylindrical concave surface and downwardly directed semicylindrical convex surfaces. A guide member is slidably retained between the bottom surface and the concave surface, and an annular member projecting into and fixed to the skirt defines spaced apart semicylindrical concave surfaces each engaging portions of the convex surfaces.
