Timing belt is also called Camblet and it maintains the synchronous operation of crankshaft and camshaft with each other. Consequently, it maintains the closing and opening of valves at the right times, so that they do not clash when the piston rises up. It maintains the engine’s bottom half in synchronism with its top half. It is actually a rubber belt which regulates the timing of the internal combustion engines of the vehicle. This is critical and if the timing belt fails to function, the engine may incur severe damage. Timing chain or belt connects the crankshaft to the camshaft(s), which then controls the closing and opening of the valves of the engine. The construct of the timing belt differs among engines. In a 4-stroke engine, the valves should close and open for once in every revolution cycle of the crankshaft. In certain engines, the function of the timing belt is also to operate other components of the engine, for instance, the oil pump and the water pump.
The cambelt or timing belt has a main function in the inner mechanisms of the vehicle. It synchronizes the operation of several parts of the engine, between the crankshaft and camshaft. Hence, a damaged timing belt can have adverse impacts on the engine. Moreover, the repairs for engine damage are very costly.
Just as every part of the car, the belt wears out with time and gets brittle. The recommended date for timing belt replacement is mentioned in the manufacturer’s manual for the vehicle.
Certain vehicles do not have a rubber belt and a timing chain is present in place of it. Both these components serve the same purpose, but the service interval is only for the timing belt.
