Title: Ignition timing control device for engine
Inventor: YAYOSHI SADAHIKO
IPC: F02P5/15
Filed: 1990-01-22
Abstract: PURPOSE:To effectively restrain and prevent the occurrence of shock at the time of operations except idling, by receiving the output of an operating condition detecting means, and thereby limiting a degree of slow change of target ignition timing at the transient time in a transient ignition timing operation means at the time of idling. CONSTITUTION:As a limiting means 26 is out of action when an engine is in operation except idling, ignition timing is thereby slowly changed toward a target ignition timing in accordance with the target ignition timing at the transient time. This thereby allows the combusting condition of air-fuel mixture to be slowly changed in such a way that torque produced is smoothly changed, which will thereby never produce any shock. On the contrary, the limiting means 26 is in operation at the time of idling, the degree of slow change in the target ignition timing at the transient time is limited to a greater extent than in engine operating conditions except idling. This thereby causes the produced torque to be quickly increased when an engine load is abruptly increased, for example, when an on-vehicle air-conditioner is actuated at the time of idling.
