A harmonic balancer (sometimes called crankshaft damper, torsional damper, or vibration damper) is the same thing as a harmonic damper except that the balancer includes a counterweight to externally balance the rotating assembly. The harmonic balancer often serves as a pulley for the accessory drive belts turning the alternator, water pump and ...
The part number on the harmonic balancer pulley can be compared to those given to Mercedes-Benz dealers in the Service Campaign notice [30] to determine if the part is a faulty original or has been replaced with the updated part. Replacement of the faulty part with the updated part should be a permanent solution to this problem.
The Holden straight-six motor is a series of straight-six engines that were produced by General Motors Holden at their Port Melbourne plant between 1948 and 1986. The initial Grey motor was so dubbed because of the colour of the cylinder block, later motors came in the form of a Red, Blue, Black, and the four-cylinder Starfire engine.
Some engines, such as GM's Premium V family, use crank position sensors which read a reluctor ring integral to the harmonic balancer. This is a much more accurate method of determining the position of the crankshaft and allows the computer to determine, within a few degrees, the exact position of the crankshaft (and thereby all connected ...
Torsional vibration is a concern in the crankshafts of internal combustion engines because it could break the crankshaft itself; shear-off the flywheel; or cause driven belts, gears and attached components to fail, especially when the frequency of the vibration matches the torsional resonant frequency of the crankshaft.
This engine produced 200 hp (149.1 kW). Design project XP-790 was originally meant to be the basis for a front-wheel drive replacement for GM's E-body cars, and incorporate flat-10 engines based on the P-10. Project XP-787 was split off from XP-790 to allow further development, while XP-790 was returned to the Research Studio, where it became ...
The tuned mass damper was introduced as part of the suspension system by Renault on its 2005 F1 car (the Renault R25), at the 2005 Brazilian Grand Prix.The system reportedly reduced lap times by 0.3 seconds: a phenomenal gain for a relatively simple device. [1]
Balance shaft in Ford Taunus V4 engine.. Balance shafts are used in piston engines to reduce vibration by cancelling out unbalanced dynamic forces. The counter balance shafts have eccentric weights and rotate in opposite direction to each other, which generates a net vertical force.
