A component grouping designed for specific engine types, typically incorporating a single, multi-ribbed belt to drive multiple engine accessories. This setup replaces older V-belt systems, streamlining the engine’s accessory drive mechanism. An example is a complete assembly intended for use with a particular engine block, featuring a pulley set, belt, and necessary mounting hardware for accessories like the alternator, power steering pump, and air conditioning compressor.
The implementation of this system offers several advantages, including simplified maintenance due to a single belt needing replacement, improved belt life through better tension distribution, and reduced slippage leading to more efficient accessory operation. Historically, the transition to this type of drive system marked a significant improvement in engine design, enhancing reliability and reducing the complexity of accessory drives. The system contributes to a more compact engine bay layout and facilitates easier servicing procedures.
