Best place is: http://auto.howstuffworks.com/engine.htm
As your piston goes down it fills with the gas and air mixture from a valve. The valve is closed and the piston comes up and compresses this mixture. Your spark plug sparks and throws the piston back down and this happens over and over. Take a 4 cylinder for example. The 4 pistons are connected to a crank. Your valves are connected to your cam. Two of the pistons will be up and ready for a spark while the other two are down being filled with air and gas. That is the best way I can put it. Look at the diagram from the link above.

Engine work when spark plug ignite gasoline and cause piston to pump up and down and up and down repeatedly until engine run out of gas and go dead.
