TECHNICAL INFORMATION ON ENGINE VIBRATION - Typical Engine Performances
Fig 1: 4th Order Citations - 8 Cyclinders
The waveform shown in Figure 1 is a 4th order torsional vibration (four spikes per rotation). The frequency of the vibration changes with engine RPM. For example, at 4600 RPM the frequency of the 4th order vibration is 307 cycles per second, or “Hertz” (HZ), the units of cycles per second.
Fig 2: 3rd Order Citations - 6 Cyclinders
An inline 6 cylinder engine has 3rd order torsional vibration - 3 spikes per revolution and of a greater amplitude than in the V8 engines
Fig 3: 2nd Order Citations - 4 Cyclinders
4 cylinder engines produce even greater amplitudes of vibrations than an inline 6 or V8 as they have 2 pulses per revolution - this type of engine will benefit greatly by fitting a harmonic balancer that can absorb damaging torsional vibration.
