PCT No. PCT/JP91/00033 Sec. 371 Date Sep. 26, 1991 Sec. 102(e) Date Sep. 26, 1991 PCT Filed Jan. 16, 1991 PCT Pub. No. WO91/10823 PCT Pub. Date Jul. 25, 1991.A fuel blending ratio detecting method is provided wherein a feedback compensation coefficient KFB is computed on the basis of an air/fuel ratio responsive output Vo of an O2 sensor, and a current blending ratio compensation coefficient KB is multiplied by a peak mean value KPEAK of the current and preceding peak values of the computed feedback compensation coefficient KFB 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. |
