What is a timing belt

The timing belt is an important part of the engine's air distribution system. Below I will give you an introduction to timing belts.

First, I will explain the working principle of the timing belt. The timing belt converts the rotary motion of the crankshaft into the rotary motion of the camshaft by connecting it to the crankshaft with a certain transmission ratio. The cams on the camshaft, in turn, control the opening and closing times of the valves through the power brought by the timing belt.

So how many types of timing belts are there and what are their characteristics?

Currently there are three types of timing belts, namely rubber timing belts, polyurethane timing belts and steel wire reinforced timing belts.

Rubber timing belt consists of rubber and reinforced layer, which has good elasticity and abrasion resistance and is suitable for most automobile engines. Its life span is generally around 5 years.

Polyurethane timing belt is a high-performance timing belt with high abrasion resistance and high temperature resistance, commonly used in high-performance automobile engines, such as racing cars. Its life can generally reach about 8 years.

Steel wire reinforced timing belt is a timing belt designed for high power engines with a high strength steel wire reinforcement layer that can withstand greater tension and load. It is more common in some high-end luxury models and transportation vehicles, and its service life can usually reach more than 10 years.

Timing belts need to be inspected and replaced regularly to avoid breakage due to age or wear. Generally speaking, the replacement interval for common vehicles can be determined based on the number of kilometers (e.g., around 60,000 kilometers) or years (e.g., 2 years). At the same time, if you observe cracks on the surface of the timing belt, a very strong rubbery odor in the belt body, or strange noises when driving, etc., you should consider replacing it in a timely manner.
