ABSTRACT:
An internal combustion engine, especially a radial engine, with a crankcase, a crankshaft, cylinders, connecting rods on the crankshaft, and with pistons attached to the connecting rods and arranged to reciprocate within the cylinders. Each connecting rod is attached with one bearing face on one journal in the crankshaft, has webs on each side of the bearing face, and is attached to the journal by strips that enclose the webs. Each strip enclosing a web on one connecting rod is part of a groove in the journal, whereby space is left, once the connecting rod has been inserted, between the webs and the strips and there is an aperture in the strips for inserting the webs, and hence the connecting rods, large enough to allow insertion of the connecting rods at an angle to their operating states and maintenance therein by the strips that enclose them. Alternatively, the end of the connecting rod toward the piston constitutes a concave bearing face and the piston has a matching convex bearing face with the same radius of curvature. In this version, the radius of curvature is selected such that the articulation between the connecting rod and the piston is above the end of the connecting rod adjacent to the piston.
