ABSTRACT:
There are provided a counter, a memory device which stores a combustion delay information, that is an information regarding the time delay between ignition initiation and combustion, and a processor. In response to a clock pulse the counter measures the interval between adjacent combustion initiation points and produces a count information corresponding to the combustion interval. The combustion delay information is read out of the memory device by the count information. The processor produces an ignition time information in response to the count information and the combustion delay information. The ignition time information contains an information corresponding to the difference between the combustion initiation points and the combustion delay time, and is used to generate a succeeding ignition initiation time.
