As the piston moves up and down, the connecting rod is moving with it. The rod is attached with a pin (the wrist pin) so it can swing a little from side to side.

Unlike Honda’s oval pistons, which were positioned longitudinally—with their long side parallel to the crankshaft and used two connecting rods per piston—Ferrari has flipped this orientation ...

By Loz Blain November 13, 2022 Transcend says its two-piece Thunder Rods replace standard connecting rods, and deliver a huge whack of additional low-end torque while eliminating piston rock ...

Using pill-shaped pistons and a novel connecting-rod design, Ferrari has a way of making its V-12s shorter. Ferrari is not the first to dream up an oval-piston engine. Honda actually raced and ...

If they come out of place, the wrist pin will go off-kilter. A cascade of internal failures results, including broken piston rods and damaged pistons.

Take, for example, floating wristpins for racing pistons. In stock engines, the wristpins are pressed into the small end of the rod and allowed to float in the piston's pin towers.

In this analysis, the multi-degree freedom mass-conserving mixed-EHD equations are solved to determine the coupled pin rotation and friction. Other bearing characteristics, such as minimum film ...

Half of the big end is in the connecting-rod main body, and the other is the cap. The "small end" is machined to accept a piston pin, and frequently contains a bearing or bushing.

The hard and slippery diamond-like coating, or DLC, holds promise for cylinder liners, piston rings, and wrist pins, where it can elimi­nate the need for bearings between the pin and connecting rod.

A short-block is comprised of major components such as the cylinder block, the crankshaft, connecting rods, and pistons. These are just the big components you can’t fit down your pants.

Scat tells us crankshafts are a series of main and connecting rod journals flanked by large counterweights engineered to “counter” the weight of the connecting rod and piston along with ...
