The cylinders are lubricated by continuous timed injection of consumable lubricant, formulated to protect the cylinders from wear and to neutralise the acids formed during

As a piston descends, it compresses incoming combustion air for the adjacent cylinders. This also serves to cushion the piston as it approaches bottom
