Engine air-fuel ratio controller |
摘要 |
A learning value of a multiplication term for correcting a basic injection amount and a learning value of an addition term for correcting the basic injection amount are stored in a memory. The learning value of the addition term is converted to a proportion relative to the basic injection amount, and these learning values are modified such that the sum of the proportion and the multiplication term lies within a predetermined range. The proportion of the total learning values relative to the basic injection amount is thereby suppressed to a constant level so that the effect of incorrect learning on air-fuel ratio control is also suppressed.
