Balance Shaft, Glossary and Terms, Automotive, Motorcycle, Boat Dealers
List of United States Automotive, Motorcycle, Boat, Dealers, Service Stations
A shaft designed so that, as it rotates, it vibrates in a way that reduces or cancels some of the vibration produced by an engine. Not essential to an engine's operation, balance shafts are nonetheless becoming increasingly common as a means of engine refinement. Balance-shafted four-cylinder engines use two shafts turning in opposite directions on either side of the engine's crankshaft. A single balance shaft is used when fitted to three-cylinder and V-6 engines.
