Engines

The basic way all engines work is to suck in a mixture of fuel and air, compress it, ignite it either with a spark plug or by self-igntion in the case of a diesel engine, allow the explosion of combusting gasses to force the piston back down and then expel the exhaust gas. The vertical movement of the piston is converted into rotary motion in the crank via connecting rods. The crank then goes out to the gearbox via a flywheel and clutch, and the gearbox sends the rotary motion to the wheels, driving the vehicle forward. Engines are devices that burns fuel to produce mechanical power and convert heat energy into mechanical energy.
