Development of Active Control Engine Mount System which Reduces Higher Harmonic Vibration

Article of Honda R&D Technical Review Vol.22 No.1

Summary

The range of three-cylinder drive can be increased in order to boost the fuel efficiency performance of V6 cylinder-on-demand engines. The use of three-cylinder drive increases the combustion pressure per cylinder, and also increases engine vibration not only at the fundamental order of combustion, but also at higher harmonic frequencies. A new active control engine mount (ACM) system was developed to respond to this higher harmonic vibration in order to satisfy commercial demands for noise and vibration (NV) performance. The operation of an ACM generates higher harmonic vibration other than the vibration produced by the engine. The new ACM system applies sine-wave drive control and multi-order frequency control in order to reduce these two forms of higher harmonic vibration. In addition, the use of a regenerative circuit has reduced heat production, helping to enable a reduction in size of the electronic control unit to be reconciled with reliability. Tests of the system in an actual vehicle showed that NV performance was increased even when an expanded range of three-cylinder drive was employed.
