Piston information:
The function of the piston is to act as a movable plug in the cylinder, forming the bottom of the combustion chamber. There is an airtight seal between the piston and the cylinder wall - so the only way for the hot combustion gases to expand is to force the piston down. It's the same principle behind a cannonball, but instead of flying into someone's beloved corsair, a spinning crankshaft pushes the piston back into the cylinder and the cycle repeats.
