So assume you have a block with a 9.00-inch deck height, 6.000-inch connecting rods, and a stroke of 3.75 inches. ... You can learn how to calculate piston compression height with this easy guide.

Ferrari submitted a patent for a super interesting engine anatomy comprised of pill-shaped pistons and two connecting rods joined into one. First, let’s observe a traditional piston and cylinder.

The free-piston engine has some similarities to the OPOC but generally only uses two pistons per module. The pistons are attached to each end of a solid connecting rod and oscillate back and forth ...

When the connecting rods are weighed each end of the rod is weighed to get the total weight. The Scat box markings match the weight indicated on this scale—452.2 grams for the big end. See All ...

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.
