As it moves upward, it compresses the charge, ignition occurs, and the . 7. Add to cart. Cast iron easily conforms to the cylinder wall. This prevents the ring from seating fully against the cylinder wall and reduces the compression of the gas in the combustion chamber. If you have the pistons machined and decide to go back with the pins be sure to install them on the compression side of the piston, some mfg put them on the crankcase side, the gap with the pin ends up being the ring gap even with a step cut ring, compression doesn't travel "line of sight", it will sneak around back of the ring and go out the gap. Which has 2 rings located under the compression ring. These rings vary in their cross-section. Middle ring is the second ring and helps in sealing the combustion chamber from the crank case as well as guiding the engine oil back down to the crank case.
