This system uses a single, continuous belt to drive multiple peripheral devices in an automotive engine, such as the alternator, power steering pump, water pump, and air conditioning compressor. A key component is the grooved wheel fixed to each accessory and the crankshaft, over which the belt runs. These wheels vary in size and grooving, depending on the torque requirements of the driven accessory.
Utilizing a single belt simplifies engine design, reduces weight and cost compared to older multi-belt systems, and improves reliability. Its continuous loop design and tensioning system also minimize slippage and vibration. This evolution from V-belts to the single-belt system was a significant advancement in automotive engineering, contributing to greater engine efficiency and reduced maintenance.
