What is the Function of a Timing Belt?

[Harrison]

The timing belt is a crucial belt that connects and synchronizes the operation between the engine crankshaft and camshaft. Below are the relevant details: 1. Timing Gear Belt: The timing gear belt serves as the intermediate transmission component linking the camshaft timing gear and the crankshaft timing gear. It transfers the motion from the crankshaft to the camshaft, replacing the commonly used transmission gears or sprockets. It features low noise, a constant speed ratio, and reliable transmission. 2. Consequences of Timing Belt Failure: If the timing belt malfunctions or even breaks, the engine will be unable to perform normal fuel-air mixture combustion according to the preset ignition timing angle. Additionally, the valves will fail to operate as per the preset travel path dictated by the crankshaft driving the camshaft, ultimately leading to valve damage.
