Title: Ignition timing control device
Inventor: SATOYA KOUICHI
IPC: F02P5/15
Filed: 1982-07-08
Abstract: PURPOSE:To prevent temporary drop of the output power of engine by advancing the ignition timing a little from the normal timing for a certain specified period of time when the clutch for transmission of the torque to a supercharger is in engagement. CONSTITUTION:A supercharger control valve 10 is closed to send air in the supercharger 6 to the engine, when the degree of opening of a throttle valve 11 exceeds a certain preset value, and is opened gradually with lessening degree of opening of the throttle valve 11 to reduce the amount of air to be sent to the engine 3. A drive belt 15 is stretched over between the drive shaft of supercharger 6 and the crank shaft 14 of engine 3, where rotation of drive shaft 13 is performed through an electromagnetic clutch 16. Application of voltage to this clutch is made when the degree of opening of the throttle valve 11 exceeds a certain specified value, and a signal corresponding to this clutch voltage is put into an ignition command part 20. This ignition command part 20 feeds an ignition command signal to the ignitor 22 so that the ignition timing is a little advanced for a certain fixed while after the electromagnetic clutch 16 is put in engagement. Thereby temporary drop of output of the engine is prevented.
