A majority of the vehicles on the road today with either diesel or petrol engines in them are only able to mechanically work if they are timed properly. Engine timing on a vast majority of todays vehicles is either done by the use of a synthetic rubber belt or a steel timing chain.

The importance of engine timing is not easy to explain but we will give it a shot to make it easy to understand. Using a four cylinder single overhead cam engine as an example, there are two main rotating assemblies on the engine itself, one being the crankshaft and the other being the cam shaft.
