A device for controlling ignition timing in an internal combustion engine which can provide change of output as demanded. A target ignition timing is found by correcting a basic ignition timing found corresponding to engine speed and load. The target ignition timing is compared with a previous practical ignition timing. If the target ignition timing is more advanced than the previous practical ignition timing, an advancing angle is calculated in accordance with the amount of the load change in such a manner that the advancing angle is small when the load change is small and advancing angle is large when the load change is large. The ignition timing is advanced from the previous practical ignition timing to the target ignition timing by the calculated advancing angle. <IMAGE> |
