PCT No. PCT/JP91/00034 Sec. 371 Date Sep. 26, 1991 Sec. 102(e) Date Sep. 26, 1991 PCT Filed Jan. 16, 1991 PCT Pub. No. WO91/10824 PCT Pub. Date Jul. 25, 1991.A fuel blending ratio detecting method is provided which includes a feedback computing compensation coefficient KFB on the basis of an air/fuel ratio responsive output Vo of an O2 sensor, computing a feedback learned value KLRN on the basis of the feedback compensation coefficient KFB at intervals of a predetermined period, and multiplying the current blending ratio compensation coefficient KB by this feedback learned value KLRN to compute the next blending ratio compensation coefficient KB. Thus, the quantity of fuel supplied to the internal combustion engine can be always controlled accurately on the basis of the computed blending ratio compensation coefficient. |
