The Hemi's cylinder deactivation system operating zone was increased, thanks to active
vibration dampers on the frame and Active Noise Cancellation in the cabin; that provides another 0.5 miles per gallon (mpg) on the highway.
Audi's aluminum block, 3.6 - liter V - 8 engine is indeed powerful, with 32 valves, two cams, 10.6 to 1 compression,
vibration dampers on the crankshaft and prodigious horsepower - 240.
The Fix: Volkswagen will replace the number two cylinder injector line and will put
vibration dampers on all four injector lines.
This isn't really unexpected, since the PTU acts like a big
vibration damper on the front of the crankshaft.

vibration damper and plenty of switches
on the left and right side.

dampers have a longer rebound stroke to eliminate smaller
vibrations from poor road surfaces, while the rear subframe is now mounted
on isolated bushings to further improve the NVH performance of the suspension.
Special body
dampers mounted up front
on the frame rail and in back under the cargo area help dampen body
vibrations for better control and precise steering.
A torsional
vibration damper, which works
on the principle of a centrifugal pendulum, allows the engine to behave well at low RPMs.
Noise and
vibration have been reduced by the use of a double torsional
damper on the crank pulley, while fuel efficiency is supported by the use of D - 4S direct fuel injection, Atkinson cycle operation, optimized VVT - i operation and a high compression ratio.
The suspension is stiffer, with a Performance Chassis
Damper (seen also
on the 370Z NISMO) to smooth out any body
vibrations that the extra stiffness would stimulate.
For example, while driving
on rough surfaces, the application of short - stroke
damper movement allows the main piston valve absorb the small
vibrations for a comfortable ride.
For the 2019 Ram 1500, FCA engineers broadened the operating zone of the Fuel Saver Technology via the addition of a pair of active
vibration dampers, mounted
on the frame, and Active Noise Cancellation technology in the truck cabin.

on a Lexus, a unique lateral performance
damper system has been designed to absorb and minimize body
vibrations to offer a more linear steering feel and further enhanced ride comfort.
