Why do cars burn petrol?

   Petrol goes from your gas tank to the carburator where it is mixed with air. It is then fed to the cylinder, compressed by the piston, and ignited which pushes the piston down. The piston turns the crankshaft which turns the transmission which turns the driveshaft which turns the axle which turns the wheels.
   
   In short, burning the petrol provides the energy to turn stuff and make your car go.

   Cars burn petrol because it is easily combustible and can easily ignite with a small spark which makes it ideal for car engines which run on tiny explosions, which is when petrol is ignited with the use of a spark plug.
