Belt Tensioner Pulley 11287627053 B For BMW F02 E71

The tensioner plays an important role in the driving process of the car, mainly in the following aspects:

1. Maintain the stability of the timing system: The tensioner is a key component of the timing system, and the engine can run at a proper time by maintaining the correct phase relationship between the camshaft and the crankshaft. The tensioner prevents the chain or belt from loosening or jumping teeth during operation by tensioning and adjusting the tightness of the timing chain or belt, thus maintaining the stability of the engine and the accurate operation of the valve and fuel injection system.

2. Reduce the vibration and noise of the chain or belt: The tensioner reduces the vibration and relaxation of the timing chain or belt during operation by providing proper tension. This is helpful to reduce the friction and noise between the chain or belt and other parts, and improve the running stability and riding comfort of the engine.

3. Prevent the chain or belt from slipping and falling off: The tensioner prevents the timing chain or belt from slipping or falling off by keeping it in close contact. This is very important for the normal operation of the engine, because once the chain or belt falls off, the phase relationship between camshaft and crankshaft will be lost, which may lead to engine damage.

4. Adjust the working range of the timing system: The design and adjustment of the tensioner can affect the working range of the timing system. By adjusting the position or tension of the tensioner, the phase difference between the camshaft and the crankshaft can be changed, so as to adjust the intake and exhaust time of the engine to adapt to different working conditions and performance requirements.

In a word, the tensioner plays an important role in maintaining the stability of the timing system, reducing vibration and noise, preventing the chain or belt from slipping and falling off, and adjusting the working range of the timing system. They have a key impact on the normal operation and performance of the engine, and need to be kept in good working condition and inspected and maintained regularly.
