Title: Air-fuel ratio learning control method
Inventor: AMANO MATSUO
IPC: F02D41/00
Filed: 1984-03-28
Abstract: PURPOSE:To simply perform the learning of an air-fuel ratio correction factor by fetching the difference between the predetermined portion of the air-fuel ratio correction factor and a reference value as a learning value when the air-fuel correction factor is out of a range between the preset upper-limit value and lower-limit value. CONSTITUTION:If the maximum value alphamax of an air-fuel ratio factor is the upper-limit value or more, the difference between alphamax and 1 is made the learning quantity Kl at Step 310. If the minimum value alphamin of the air-fuel ratio factor alphamin is the lower-limit value or less, the difference between alphamin and 1 is made the learning value Kl at Step 314. If the division point is judged to have changed at Step 318, go to Step 324 to clear the counter, then go to Step 332. Accordingly, the learning value of the air/fuel ratio correction factor can be simply fetched, and the fetching can be performed with little response delay.
