Abstract
PURPOSE: To rationalize the ratio of air to fuel by storing the first and the second comparative level in a soft counter arranged in an RAM circuit of an air fuel ratio control device so as to compare with an adequate level corresponding to each running condition.
CONSTITUTION: A built-in RAM circuit of a computer which is not figured has functions of writing and reading, and has a soft counter. When a main program starts at the step 100, the signal is compared with the first and the second comparative level in the soft counter, and at the step 102, it is judged that a feedback control is necessary or not. As the result, the second level is changed at the step 104, or a control based on the settled second level is operated at the 106 step. At the step 108, it is judged that the operation for one period of the soft counter has been done, or the background disposition step, the step 110, is necessary.
