What is?
It is connected to the positive of the crankshaft when the engine head wheel, together with a certain gear ratio to ensure accurate intake and exhaust time.

role
To know the usefulness of the belt positive, first of all need to understand the working process launched . Operation of the engine includes four main steps: intake, compression, power and exhaust. Although it looks simple, but in fact, during engine operation is very complex, it is the timing of each step to be engaged with the piston, the valve motion and position of the piston and the intake and exhaust lift coordinated with each other. And the timing belt at the inside of the engine plays a role in “bridge”, the kinetic energy is transmitted to the corresponding driven parts of the crankshaft and at different steps of the timing of the piston part, a valve, etc. held in the correct position and then make normal engine operation.

Characteristics
the timing belt has been applied for a long time in the engine, and the technology is mature lower costs, less noise. Timing belt belongs to the wear and tear items, such as timing belt, once broken, it will not operate according to the camshaft timing at this time is likely to lead to valve and piston slap and cause serious damage, which is what we commonly known as the “top of the valve.” So the timing belt must be based on the original specified mileage or time replacement, and regular inspection andMaintenance, in general, cars with 80,000 km need to consider when replacing the timing belt.
