There are many types of piston engines. They use various methods to form a high pressure mixture of air and fuel at the top of the cylinder and then ignite it. When the air and fuel burn it will heat up causing it to expand. This pushes the piston down with more force then it used when compressing the air in the first place. The piston is connected to a crank which turns the up and down motion of the piston into rotating motion. The energy from the piston being pushed down is used to spin a flywheel connected to this crank which continues to rotate to make the engine replace the burnt gasses with new air and fuel and compress it so the cycle starts again.
