    摘要: A fuel blending ratio detecting method is provided which includes a feedback computing compensation coefficient K.sub.FB on the basis of an air/fuel ratio responsive output V.sub.o of an O.sub.2 sensor, computing a feedback learned value K.sub.LRN on the basis of the feedback compensation coefficient K.sub.FB at intervals of a predetermined period, and multiplying the current blending ratio compensation coefficient K.sub.B by this feedback learned value K.sub.LRN to compute the next blending ratio compensation coefficient K.sub.B. 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.

    摘要: An air-fuel ratio feedback control method for a multi-fuel internal combustion engine using a dual O.sub.2 sensor system is provided, in which the concentration of oxygen in exhaust gas on the upstream side of an exhaust gas purifier is detected, a value corresponding to the detected oxygen concentration is compared with a first target value, and the air-fuel ratio is feedback-controlled in accordance with the result of the comparison. The mixture ratio of at least two fuels is detected, and a second target value is set in accordance with the detected fuel mixture ratio. On the other hand, the concentration of oxygen in the exhaust gas on the downstream side of the exhaust gas purifier is detected, and a value corresponding to the detected downstream-side oxygen concentration is obtained. The first target value is corrected in accordance with the difference between the obtained value and the second target value.

    摘要: In an exhaust system, there are provided an HC absorbent which absorbs HC contained in exhaust when in a specified low-temperature range and desorbs the absorbed HC when it exceeds said low-temperature range, and a catalyst capable of at least removing HC by oxidation, where the catalyst is arranged at the same position as or downstream of the HC absorbent. When it is found that the HC absorbent is in a state ready for desorbing the absorbed HC (S16, S18) and the internal combustion engine is in a specified decelerating state (S14), fuel supply to some of the cylinders of an internal combustion engine is stopped while fuel is supplied to the other cylinders (partial fuel cut) (S22).

    摘要: Terminals are connected via cables in a star-shaped fashion with respect to a HUB in a LAN. Each of the cables includes therein signal lines and power feed lines. The HUB includes therein a power feed section. The power feed section and the power feed lines of each cable are connected to measure a value of current which flows in the power feed lines. If it is judged based on the measured current value that the terminal connected to the corresponding cable is a telephone terminal, the power feeding to the corresponding power feed lines is continued. On the other hand, if the terminal is judged to be a terminal other than the telephone terminal, the power feeding is stopped.
