If you don't know this from automotive engineering, then you must know it from middle school physics. What is the name of a part that moves up and down, and transforms the fuel into actual motion?

In every vehicle there are cylinders. Most cars have four, six, or eight of them. Inside each of those cylinders is a piston that moves up and down, and as it does so, it turns a crankshaft that's attached to the gearbox, which in turn moves the car's wheels.
