The timing belt is a belt that connects the engines crankshaft to the camshaft. The crankshaft is turned by the engine's pistons and tuns the vehicles drive wheels. The camshaft opens and closes valves that let fuel and air into the engine and allow burned vapors to exhaust. Timing the valves to the piston position is crucial to making the engine run.
In most engines the intake valve (allows air and fuel in) is timed to open as the piston is moving downward in it's movement. The intake closes as the piston reaches the bottom of movement and is about to come back up. As the piston rises, it compresses the air and fuel and nanoseconds before it reaches the top of it's travel a spark plug ignites the fuel (if it's a gasoline powered engine). The explosive force of the ignition forces the piston back down, which forces the crankshaft to turn. When the piston reaches the bottom again, another valve opens to allow the burned fuel vapors out of the engine. The piston moves back up to push the gases out. After reaching the top of travel the exhaust valve closes and the intake valve reopens.
With out the timing belt, the engine would have no way of correlating the opening of the valves to the placement of the pistons.
