An internal combustion engine 210 includes a variable length connecting rod assembly 218, 220, a field-sensitive fluid coupled to the connecting rod assembly 218, 220, and a circuit 170 coupled to the field-sensitive fluid for applying a field to the field...

A variable compression ratio mechanism for a reciprocating engine includes upper and lower links linking a piston pin to a crankpin, an eccentric cam equipped control shaft and a control link cooperating with each other to vary the attitude of the upper an...

A variable compression ratio mechanism for a reciprocating internal combustion engine includes upper and lower links mechanically linking a piston pin of a piston to a crankpin, and a control link mechanically linking the lower link to an eccentric cam of ...

A piston crank mechanism of an internal combustion engine includes an upper link connected to a piston, a lower link connected to both the upper link and a crankpin, and a control link through which the lower link is linked to an eccentric cam of a control...

An internal combustion engine is constructed to include a variable compression ratio mechanism. The mechanism has the following structure. An upper link has one end pivotally connected to a piston pin of a piston of the engine. A lower link is pivotally di...

A variable compression ratio mechanism for a reciprocating engine includes a connecting rod split into upper and lower connecting rod portions linked to each other through a first connecting pin. A rockable arm is oscillatingly linked at one end to the low...
