Title: Ignition timing control device
Inventor: TAWARA MASAHIKO
IPC: F02P5/152
Filed: 1986-02-14
Abstract: PURPOSE:To improve fuel consumption and drivability through shortening of a time in which an advancing angle is increased to a demand value, by a method wherein an advancing angle speed at which an ignition timing is finely advanced according to the intensity of knocking is increased. CONSTITUTION:When, in a control circuit 19, it is decided from an output from a knocking sensor 18 that knocking is present, a fine advancing angle amount is added to the correction delay angle amount of an ignition timing to prevent the occurrence of knocking. In which case, the intensity of knocking is decided, and the frequency of the intensity exceeding a given value is computed. A fine advancing angle amount determined by the frequency is deducted from the correction delay angle amount. Thus, since a time in which an advancing angle is increased to a demand value can be shortened according to the intensity of knocking, fuel consumption and drivability can be further improved.
