Device for reducing torque fluctuation of two-divided flywheels

Abstract

Abstract PURPOSE:To prevent excessive torque fluctuation of an engine, by accurately detecting that two-divided flywheels approach their resonance state to avoid resonance. CONSTITUTION:Rotational speeds NA and NB of flywheels 3 and 5 resiliently connected with each other are detected by electromagnetic pickups 9 and 10, and (NA-NB) is computed by a subtracter 11 to be inputted to a controller 12. When a predetermined rotational speed N1 at idling is reduced to reach N2 by some reasons, and difference in the rotational speed becomes (NA-NB)1 or over, the controller 12 commands an injection pump to increase fuel through an actuator 13, so as to return the rotational speed to a normal idle rotational speed N1. In the event that an elastic member 4 is damaged by some reasons, and connection between both the flywheels 3 and 5 is cut, the difference in the rotational speed becomes (NA-NB)2 and over, and accordingly an engine 1 is rapidly stopped.
