Title:
IGNITION DEVICE FOR INTERNAL COMBUSTION ENGINE
Document Type and Number:
WIPO Patent Application WO/2015/156216
Kind Code:
A1
Abstract:
In an ignition device for an internal combustion engine according to the present invention, continuous spark discharge of spark plugs is performed using either: a multiplexed signal (IGWc) obtained by multiplexing discharge continuation signals (IGW#1-4) of separate cylinders; an integrated signal (IGC) obtained by adding the discharge continuation signals (IGW) and a secondary current command signal (IGA) to an ignition signal (IGT); or a signal obtained by adding the secondary current command signal (IGA) to the multiplexed signal (IGWc) and the integrated signal (IGC). As a result of this configuration, the number of signal lines connecting an ECU and a controller can be reduced, and the signal line for the secondary current command signal (IGA) can be eliminated.
