Title:
IGNITION TIMING CONTROL DEVICE AND IGNITION TIMING CONTROL SYSTEM
Document Type and Number:
WIPO Patent Application WO/2015/079601
Kind Code:
A1
Abstract:
The present invention provides an ignition timing control device and an ignition timing control system whereby changes in the operating state of an internal combustion engine can be promptly dealt with. At an ignition timing adjustment device (43), on the basis of a knocking signal obtained from a knocking detection device (41) and a reference ignition signal (A) obtained from an internal combustion engine control device (37), ignition timing can be corrected in a region on the retard side of a maximum advance value such that appropriate ignition timing can be achieved. In other words, in response to the detection of knocking, the ignition timing is promptly retarded with respect to the reference ignition timing obtained from the internal combustion engine control device (37), thereby enabling an output signal from the ignition timing adjustment device (43) to be promptly adjusted.
