ABSTRACT:
This invention relates to new and useful improvements in the mechanism comprising the crankshaft of internal or external combustion engines and also for use in other externally heated closed vapor cycle systems. In the engine system presented an eccentric is placed between the connecting rod and crankpin and is made to rotate with each revolution of the crankshaft by use of eccentric gearing. Rotation of the eccentric augments the simple harmonic motion induced by rotation of the crankpin thus changing the reciprocating motion of the piston in a manner which improves the efficiency of the mechanical conversion process.
