| titleOfInvention | Air-fuel ratio controller for internal combustion engine |
| abstract | (57) [Abstract] [Purpose] An air-fuel ratio determination means for determining that the air-fuel ratio of the internal combustion engine has been inverted after a predetermined delay time after the output of the oxygen sensor provided upstream of the catalyst has been inverted, and the air-fuel ratio determination means provided downstream of the catalyst. In the air-fuel ratio control device that corrects the delay time according to the output of the oxygen sensor, the delay time is prevented from extending beyond a predetermined time. [Structure] The cycle T of the air-fuel ratio control increases or decreases in proportion to the length of the delay time. Therefore, in step 1401, it is determined whether or not the cycle T exceeds a predetermined time T1, and when T> T1, the integration constant K1 of the air-fuel ratio correction coefficient is set to step 14 At 02, the predetermined value α is increased. As a result, the change in the air-fuel ratio correction coefficient per unit time becomes large, and the air-fuel ratio can be largely corrected even with a short delay time. |
