| abstract | (57) [Abstract] [Purpose] When the oxygen sensor deteriorates, the feedback correction coefficient itself is corrected more appropriately than before, and emission deterioration at the time of deterioration is prevented. [Structure] During feedback control during steady operation, the feedback control is temporarily stopped to shift to open loop control for sweeping the air-fuel ratio, whereby the output OXAD of the oxygen sensor 5 is forcibly oscillated, and its output The response time TLRN at which OXAD reverses from lean to rich or the response time TRLN at which rich changes from lean to lean is measured, Then, the feedback control is resumed, and the rich delay time TDR or the lean delay time TDL is determined based on the measured response times TLRN and TRLN. |
