That ignition creates an explosion that pushes the piston back down. As the pistons rise into the cylinders, the air and fuel mixture will be injected and then ignited by your spark plug. This precise timing is what allows your engine to function the way it was designed to. As the camshaft rotates the valves at the top of your cylinder will open allowing the pistons to pass through. That allows the camshaft to keep time with the crankshaft. This motion causes the gear on the end of the crankshaft to rotate which in turn makes the timing belt rotate. When the crankshaft in your engine turns, the pistons will rise in your engine cylinder. Unlike a serpentine belt which is smooth on both sides, your timing belt has notched teeth on the inside that allow it to grip the gears when it is looped over the ends of both your camshaft and your crankshaft.
