Reciprocating piston IC engine - has piston coupled by two connecting rods to contra-rotating crankshafts coupled together

摘要

The piston in an IC engine has connecting rods coupling the piston (5) to two contra-rotating crankshafts (151, 15r). There are two connecting rods between the piston and the crankshafts, which are in turn coupled to each other. The rods can be coupled to the piston at points spaced apart (A), the attachment points (10) being symmetrically situated. USE/ADVANTAGE - High efficiency and quiet running of IC reciprocating piston engine.
