The document discusses the function and structure of pistons in internal combustion engines, highlighting how they transmit gas forces from fuel combustion. It also describes the components of a piston, including the combustion chamber and crankcase, as well as four types of pistons: trunk, crosshead, slipper, and deflector. For further details, a link to a relevant website is provided.
