Torque fluctuation control device of engine

Abstract

Abstract PURPOSE:To invariably suppress torque fluctuations favorably by providing an electric driving device and a power generating device applying positive and reverse torque to a crank shaft and controlling the operating timing and periods of individual devices in response to the full-cylinder operation and the partial-cylinder operation. CONSTITUTION:Two types of rotary solenoid coils 8, 9 and a magnetic body 10 are provided on the outer periphery of a flywheel 2 fitted to the end of a crank shaft 1 of a engine. A stationary solenoid coil 7 is provided on the inner periphery of a fitting member 6 fixed to a cylinder block 3 around the flywheel 2. A electric deriving device applying positive torque to the crank shaft 1 is constituted by exciting the stationary coil 7 and the rotary coil 8, and a power generating device applying reverse torque to the crank shaft 1 is constituted by exciting the rotary coil 9 with the stationary coil 7 connected to a rectifying circuit. Both devices are controlled so that the operating periods during the partial-cylinder operation are made longer than those during the full-cylinder operation.
