The difference between timing chain and timing belt, which is better timing belt and timing chain

The timing belt or timing chain is the crankshaft wheel, camshaft wheel, and tensioner wheel that connect the engine, and it mainly plays the role of connecting the top and bottom. Control the movement of the cam, open or close the valve group regularly, realize the intake or exhaust conditions, and generally ensure the normal operation of the piston movement.

Difference between timing chain and timing belt

The function of the timing chain and the timing belt is the same, but the material is different. The timing belt is a rubber part, and the timing chain is a metal chain.

Timing belt or timing chain which is better

Comparing the two, it is impossible to say which one is better, each has its advantages and disadvantages. Whether it is a timing chain or a timing belt, they play a very important role in the operation of the engine. The transmission of the engine needs the assistance of the transmission belt. They are connected with the crankshaft and cooperate with a certain transmission ratio to ensure the intake and exhaust time. precise.

Timing belts have low cost, low transmission resistance and low noise, but belts are consumables with shorter lifespans and higher failure rates than timing chains. The timing belt replacement cycle varies with the structure of the engine. Generally, the timing belt needs to be replaced when the car travels about 60,000 to 100,000 kilometers. The specific replacement cycle is subject to the vehicle maintenance manual.

The timing chain has large transmission resistance, louder noise and higher cost. Both the manufacturing cost and the maintenance and replacement cost are higher than the timing belt. However, the timing chain is not easy to be damaged, has a longer life, less maintenance in the later period, and is more reliable and durable. In the long run, the advantages of chains are higher than belts, and more cars use timing chains.
