The flow of air coming into the engine is maintained by various mechanisms and they are controlled by automotive belt or timing belt. But, it's really difficult to know which one is better. So let's understand these two things in deep to know which one is better.
Automotive Belts
In the early ages of the automotive industry, most of the people were using automotive chains because of their ruggedness, durability and simplicity. Most of the automotive belts are roller chains made out of steel and they are similar to the type you would find in a bicycle or motorcycle. Steel is a really durable material and it's hardness, tensile strength, and modulus of elasticity makes it a good material for a durable timing drive system in the engine.
Advantages:
Affordable: The manufacturing of camshaft sprockets for Automotive Belts and the actual chains are simple compared to timing belt components. This makes the cost down for the car companies as well as for the user.
Durability: With the help of steel and the accurate lubrication system, this belt typically lasts for more than 1,50,000 miles. So you will be required to spend less the maintenance.
Timing Belt
To decrease the noise and increase the efficiency of the engine, timing belts play a crucial role. The manufacturing of the Timing Belts contains the steel wire-reinforced rubber that has cogs that fit in the corresponding grooves of the camshaft and timing pulleys. The rubber belts rotate that's why it can naturally flex around the pulleys. With this mechanism, the rubber to metal contact does not require any kind of lubrication system. To remove the slippage and decrease the friction, Torque is transferred through the cogs. And compared to automotive belts, timing belts are really efficient to power transmission. Longevity is their main downfall.
Advantages:
Silent Operation: There is no metal to metal contact happening in the mechanism of timing belts. And also you don't find any mechanical linkages that are continuously bending.
Lightweight: With the help of less inertial forces, it offers good engine power and responsiveness.
Low Maintenance: The replacement cost of a timing belt is affordable. You do not require to remove the valve cover and you can easily access the pulleys.
Conclusion
Automotive belt and timing belts both have advantages and disadvantages. So with the help of the above discussion, you can easily select a good belt for your vehicle.
