| DescriptionMKT | All internal combustion engines display crankshaft torsional vibration As the piston rises and falls so does cylinder pressure The changing pressure results in forces being transmitted along the connecting rod and applied to the crankshaft journal The TCI Rattler counteracts those vibrations by using internal rollers that automatically offset twisting forces that cause vibration see Fig 1 The Rattler is an absorber that eliminates the root cause of torsional vibration It is effective for the entire RPM range and extends crankshaft and bearing life as well as increases valve train stability and life The design does not utilize viscous fluids and requires virtually no maintenance And the units timing marks are etched onto the body and cannot move relative to crankshaft centerline The Rattler is also lighter in weight than most units of the same size and material construction Its design features steel rollers centrifugal pendulums that fit loosely into a specific number of holes By using patented exact mathematical relationship the rollers will roll forward during compression stroke and backward during power stroke to keep engine speed variation and vibration to a minimum The rollers actually store and release energy back into the crankshaft rather than converting it to heat energy as dampers do Rattlers are not frequency specific but are based on the number of cylinders used in the engine or events per revolution so they are practical for street use as well as oval track and drag strip useCNCmachined to exacting tolerances |
