Flexible connecting rod

摘要

An internal combustion engine has a connecting rod which interconnects the engine crankshaft with a piston. The connecting rod is a flexible member which has one section connected with the piston and another section connected with the crankshaft and a spring or lost motion member interconnecting the two sections. When the forces imposed on the flexible connecting rod are sufficiently high, the spring member will permit the two sections to approach each other, thereby shortening the length of the flexible connecting rod and increasing the volume in a combustion chamber formed between the piston and an engine cylinder in which it is reciprocably disposed.
