I've read somewhere where a secondary counter rotating shaft with weight is use to counter harmonics forstraight 4 cylinder engines - patented by Mitsubishi??? but these were basically directly driven via chain. is my understanding that DMFW has some sort of spring/elastomer coupling the two disks.
Question, with direct coupling, is the harmonics cancellation accomplished independent of engine rpm.
Question, with spring between the two, taking out harmonics from 700 rpm to 7000 rpm, 10x range would need spring to become 10x stronger??
I may have found answer to question here
