Hi,
Can someone explain the lubrication mechanism for a piston in a typical automotive internal combustion engine? If the walls in the piston chamber are coated with oil, the lubricant should also burn along with the petroleum during the combustion phase (leaving problematic residues), so, is the oil somehow "squeezed" out of the chamber as the piston shoots back down after detonation? And if so how is this accomplished? Perhaps the skirt of a piston relies on a solid lubricant coating? Or does the motor oil simply dissolve and carry away the soot and burnt residues from the chamber?
