Connecting Rod

The connecting rod carries the force from the piston to the crankshaft, it is constantly subjected to stretching, squashing, and bending forces as it acts as the intermediary in this push-pull relationship. The connecting rod needs to be structurally strong and it’s no coincidence that it takes the form of a miniature steel I-beam, similar to its bigger brothers holding up skyscrapers and bridges. The I-beam profile gives a maximum structural strength at the minimum weight cost and, like the piston, we want to keep the weight of the connecting rod as low as possible.

Piston coatings

Coatings are applied to the skirt to reduce friction between it and the cylinder wall.
Ceramic coatings can be applied to the crown and are designed to reflect heat back into the combustion chamber and decrease the amount transferred into the piston. The underside of the piston may have a non-slip coating known as an oil-shed coating which repels oil, thus reducing the weight of the assembly and allowing more effective oil cooling.
