ABSTRACT:
A basic target spark timing is determined in accordance with an operating condition of an engine. A spark timing knock corrective value is determined in accordance with the presence or absence of a knock in the engine. A spark timing learning corrective value is determined in accordance with the spark timing knock corrective value and with the engine operating condition. When a transitional condition of the engine is detected, the spark timing knock corrective value is fixed to a preset value independent of the presence or absence of the knock and also independent of the engine operating condition. A final target spark timing is determined in accordance with the basic target spark timing, the spark timing knock corrective value, and the spark timing learning corrective value. A spark is generated in the engine at a timing in agreement with the final target spark timing.
