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 ...
Harmonic damper for a 1937 Pontiac engine. Torsional vibration develops when torque impulses are applied to a shaft at a frequency that matches its resonant frequency and the applied torque and the resistive torque act at different points along the shaft. It cannot be balanced, it has to be damped, and while balancing is equally effective at ...
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.
The functional objective for the crankshaft position sensor is to determine the position and/or rotational speed of the crank. Engine Control Units use the information transmitted by the sensor to control parameters such as ignition timing and fuel injection timing. In a diesel, the sensor will control the fuel injection.
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.
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]
Murphy oil pressure gauges with switches that activate on low pressure. Oil pressure is an important factor in the longevity of most internal combustion engines. [1] With a forced lubrication system (invented by Frederick Lanchester), oil is picked up by a positive displacement oil pump and forced through oil galleries (passageways) into bearings, such as the main bearings, big end bearings ...
Harmonic Balancer - Some M112 and M113 engines used in W210 models were equipped with a harmonic balancer pulley which, due to a supplier quality problem, may fail and cause engine damage. If the rubber insert of the harmonic balancer pulley delaminates, the pulley may grind through the timing chain cover and oil pan, causing several thousand ...
