  • Vibration suppressor
    Publication number: 20070151242
    Abstract: A vibration suppressor and a vibration damper are configured in a system consisting of an internal combustion engine and an exhaust-gas turbo charger. The vibration suppressor and vibration damper are secured to an exposed place on the system which is subjected to strong vibrations. As the vibrations are the strongest in said area, the vibration-reducing means can be used to a maximum. The system consisting of the internal combustion engine and the exhaust-gas charger is improved in such a manner that the internal combustion engine can be operated in all of the rotational speed ranges without reducing the service life of individual components or the entire system.
