The PK belt alternator refers to an alternator that utilizes a PK (or Poly V) belt system for its operation. The PK belt system is characterized by its flat design and multiple ribs running parallel to the length of the belt. This design allows for a wider surface area in contact with the alternator pulley, enhancing grip and reducing slippage. The PK belt is commonly used in modern vehicles for power transmission purposes, and its integration with alternators brings several benefits.

A Poly-V TB2 belt is a type of multi-ribbed belt designed for high-performance applications. It features a series of longitudinal ribs that run along the belt's length, providing multiple contact points with the pulleys. This ribbed structure is designed for quiet operation and minimal vibration, offering an efficient means of power transmission. The TB2 designation typically indicates specific dimensions and properties of the belt, which are crucial for ensuring compatibility with the systems in which they are used.
