What is the primary function of dynamic dampers on crankshafts?

The primary function of dynamic dampers on crankshafts is to reduce engine vibration. In an internal combustion engine, the reciprocating and rotating masses create forces that can lead to unwanted vibrations. These vibrations can cause wear, damage, and operational inefficiencies if not managed properly.

Dynamic dampers work by using a counterweight that oscillates out of phase with the vibrations produced by the crankshaft. This counteraction helps to absorb and neutralize the vibrational forces, leading to smoother engine operation. By reducing vibrations, dynamic dampers contribute to improved engine longevity, reduced noise levels, and overall enhanced performance, making them an essential component in engine design.

While fuel efficiency, engine power, and operating temperature are important aspects of engine performance, they are not the direct functions of dynamic dampers.
