Abstract
An apparatus for reducing torque fluctuations of a combustion engine includes a crankshaft mounted in the engine, flywheel coupled to the crankshaft, and a first actuator and a second actuator coupled to the flywheel. The flywheel generates a counter torque to the torque generated by the engine during combustion, and the first and the second actuators are operated to adjust the magnitude and the phase of the counter torque generated by the flywheel to suppress fluctuations associated the engine torque.
