Timing Chain vs Timing Belt - What is the Difference? | Which One is Best for Engine?

Описание: The timing chain functions in the same way that a timing belt does. The difference between the two is simply the material and location. One is constructed of metal and the other, a reinforced rubber.
Either of these parts can be found in the internal combustion engine of a vehicle. Their responsibility is to keep the rotation of the camshaft and crankshaft synchronized. The camshaft in the engine controls the valves to let fuel and air in and out. At the same time, the crankshaft moves the pistons up and down. This is called mechanical timing and the synchrony of these functions is imperative. If the mechanical timing is off, damage could occur to the valves, pistons, engine, or other components. The purpose of the timing belt or chain is to ensure the harmonization by keeping each turning at the precise rate.

Timing chains

A timing chain looks like the chain on a bicycle. The timing chain has the added advantage of durability. In fact, it should last the lifetime of your vehicle. In contrast, a timing chain is a metal chain that unites the crankshaft and camshaft to make them revolving in-sync. One major advantage of using timing chain over belt is its long-lasting feature. Luckily, these chains need not be replaced after some miles. They can last until the life of your car’s engine. In addition, they contain tensioners that help to keep them working accurately and prevent loosening.

Timing chains are tremendously dependent on the engine’s oil pressure. If the oil pressure is low or incoherent, it can affect the working of the chain and can impact the engine timings.

As great and long lasting as timing chains are, there are a few things that might annoy you about them. The biggest annoyance is the noise timing chains make. They are known for being much noisier than timing belts. That said, technology in newer vehicles has made the timing chain just as quiet as engines with a timing belt.

Also, it is possible for a timing chain to break completely. Once this happens, it will cause a lot of expensive damage to your engine. You may even need to replace your engine altogether if your timing chain breaks and damages it. Engine replacement would be cheaper than engine repair in this situation.

Timing Belt

Timing belts have been around since the 1960s. They replaced the timing chain due to their smooth, quiet running and lower cost. The service life of the timing belt is estimated at 60,000 to 100,000 miles or 5 to 7 years, depending on the vehicle model.

Another benefit is their price. Because of their material and simple construction, timing belts are much cheaper to replace than timing chains. Like a timing chain, if a timing belt breaks, catastrophic engine damage can occur. That’s why it’s critical you follow the manufacturer’s recommended timing belt change interval. In most cases, this will be somewhere between 60,000 and 100,000 miles. They last about half as long as a timing chain.

The wait is finally over. I am here with YouTube's very first Mechanical Engineering Channel in HINDI.
In this channel i will upload videos related to mechanical engineering topics such as Automobile, Production, HMT, Thermodynamics, FM, CAD/CAM etc.
