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, operating them synchronously with torque fluctuations, and controlling the working quantities of both devices in response to the control operation of the number of cylinders. CONSTITUTION:Two types of rotary solenoid coils 8, 9 and a magnetic body 10 are provided on the outer periphery of a flywheel2 fitted to the end of a crank shaft 1, and 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. An electric driving 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. The working quantities of both devices are controlled so that the positive and reverse torque applied by both devices during the partial-cylinder operation is made larger as compared with that during the full-cylinder operation. |
