Combustion loads cause the crankshaft to twist and recover during operation, creating torsional vibration that can place additional stress on the rotating assembly.\u003c\/p\u003e\n\u003cp\u003eInnovators West’s damper technology uses spring-loaded inertia rings and a wet-friction clutch arrangement to manage these vibrations.
