Abstract

The engine has a reciprocating to rotary motion converter with three rods (L, R, R'), the first connected to the piston (2), the second to a fixed support, and the third to a crankshaft journal (3), with all three rods connected by a single pivot. The third rod is very short, made from four pieces in two identical pairs (12, 13) fitted round journal bearing shells, and able to pivot about three different axes (B, B', B), one for the crankshaft journal and the others for the other two rods (L, R), rotating about the tdc point.
