Description
 
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.
