=The Internal Combustion Engine= Link to how stuff works Internal Combustion web page video on the internal combustion engine How engines work ==== Combustion engines work by the expansion of hot gases. The Piston starts in the top position. As it goes down the intake valve opens and the air and fuel mixture fills the cylinder. The piston goes back up, compressing the mixture, and the spark plug ignites the mix. As the mixture explodes the piston goes down causing the drive train to spin which moves the wheels on a vehicle. ====

Inside the engine
