Investigation of Design, Manufacture, Analysis, and Test of a Composite Connecting Rod Under Compression
… constitute. By replacing metal elements such as connecting rods, cylinder caps, or a crank shaft with composite alternatives, a significant increase in performance may be achieved with respect to mechanical strength, thermal stability, and durability, while also reducing mass. Exploration of this …

Modeling of piston pin lubrication in internal combustion engines
The piston pin joins the piston and the connecting rod to transfer the linear force on the piston to rotate the crankshaft that is the eventual power outlet of the engine. The interfaces between the piston pin and the pin bore as well as the connecting rod small end are one of the most heavily …

Lubrication in the ball and socket joint of a swash plate mechanism
The tribology of the ball and socket on the connecting rod in a swash plate engine is studied in the hydrodynamic regime. The engine operates at 1390rpm with an axial load on the rod as high as 1 x 10⁴N. The instantaneous load and kinematics from a previous study for a swash plate engine was used …
