What is the function of the car timing chain
The main role of the automotive timing chain is to drive the valve mechanism of the engine to ensure that the intake and exhaust valves of the engine are opened or closed at the exact time, so as to ensure the smooth suction and exhaust process of the engine cylinder . Specifically, the timing chain precisely controls the valve mechanism of the engine, so that the intake and exhaust valves of the engine can be opened and closed at the right time to ensure the normal operation of the engine cylinder .
Timing chains offer higher reliability and durability than traditional timing belts. The timing belt, made of rubber, is quiet but short-lived and usually needs to be replaced every 60,000 to 100,000 km, otherwise it may cause engine damage . The timing chain is made of metal, has a longer life, can generally be used until the engine is scrapped, but the operation noise is larger, and the need for lubricating oil to maintain a good condition .
In addition, timing chain replacement cycles may vary by car make and model. For example, the timing chain on the VW CC is recommended to be replaced every 80,000 km driven .
The main role of the automotive timing chain is to drive the valve mechanism of the engine to ensure that the engine intake and exhaust valve are opened or closed in the appropriate time, so as to ensure that the engine cylinder can normally inhale and exhaust .
Specific role
drive valve mechanism : The timing chain through the drive engine valve mechanism to ensure that the intake valve and exhaust valve open or close at the appropriate time to ensure the normal suction and exhaust of the engine cylinder .
reliable transmission, good durability : compared with the traditional belt transmission, chain transmission is more reliable, durable, and can save space. The hydraulic tensioning device can automatically adjust the tension of the chain, making it consistent and maintenance-free for life, and the same life as the engine .
Maintenance and replacement cycle
The timing chain usually does not need to be replaced frequently, but due to its harsh working environment, it may be worn or loosened after prolonged use. Therefore, it is recommended to check the tension and wear of the chain regularly and replace it if necessary. The specific replacement cycle can be determined according to the use of the vehicle and the manufacturer's recommendations .
