Car engine in the course of work, in the cylinder continue to occur in the air, compression, explosion, exhaust four processes, and the timing of each step and the movement of the piston and the location of the match, so that the intake and exhaust And the piston lift coordination with each other, Rubber Timing Belt inside the engine to play a "bridge" role in the crankshaft driven by the power to the corresponding parts. There are many high-end cars to ensure that the timing system is stable, the use of metal chain to replace the belt. As the vehicle timing tooth belt fracture will cause damage to the engine inside the valve, the greater the harm, so the general manufacturers are on the timing of the provisions of the replacement cycle.
Timing belt is an important part of the engine air distribution system, through the connection with the crankshaft and with a certain transmission ratio to ensure that the inlet and exhaust time is accurate. The use of belts rather than gears is driven because the belt noise is small, the drive is accurate, its own changes are small and easy to compensate. Obviously the life of the belt must be shorter than the metal gear, so the belt should be replaced regularly.
The timing belt is a rubber part. As the working hours of the engine increase, the timing belt and timing belt attachments, such as timing belt tensioners, timing belt tensioners and pumps, are worn or aged.
Each belt has a specific temperature range, and any situation should not exceed this range, which ranges from -18 degrees to 158 degrees Fahrenheit. People often do not realize the importance of temperature to the belt. You can keep your belt temperature at 158 degrees, and your belt can withstand this kind of abuse. You can be in the same temperature is -18 degrees. If you exceed this temperature, it will risk the destruction of the belt, and sometimes lead to damage to the machine itself.
