Part # 570601
For 2002-2006 Acura RSX Base & Type S - K20, K20A, K20A2, K20A3, K20Z1 Engines
Fluidampr Engine Dampers are designed to control destructive vibrations which are transfered thru the crankshaft.
Each
time the air/fuel mixture inside a cylinder is ignited, the combustion
that occurs creates a torque spike that is applied to the crankshaft
through the piston and rod. This torque spike is so severe that it not
only turns the crankshaft, it actually twists the crankshaft ahead of
its normal rotation and then the crankshaft rebounds. This twisting
action is known as torsional vibration. When these torque spikes and
forces get into phase with the natural frequency, critical torsional
harmonic vibrations occur and can be seriously destructive to the
bearings and the crankshaft. Dampers are designed to control those
destructive vibrations.
Critical harmonic vibrations occur
numerous times in a engine’s operating range. Stock rubber and
elastomer-type dampers are frequency sensitive “tuned absorbers”, and
work at only one critical frequency. In the case of a stock rubber
damper, it is tuned for a factory engine’s critical harmonic vibrations.
If you change the mass of pistons, rods, or the crankshaft, you change
the natural frequency of the crankshaft assembly; therefore, the stock
damper is no longer tuned to the new frequency of vibration, and you may
be headed for early failure of expensive engine components. Dampers
also create heat while they work, and rubber is a poor dissipator of
heat. This heat and the exposure to the elements deteriorates rubber,
causing it to crack and change durometer, which then leads to inertia
ring slippage, damper failure, uncontrolled torsional vibration, and
costly engine parts breakage.
