摘要： A fuel injection valve is provided upstream of a branch-off part of a branched off intake passage, the downstream ends of the branched off passages being connected to a plurality of cylinders of an engine. The fuel injection timing of the injection valve is controlled by a pulse controller. The pulse controller operates to control the pulse timing basically according to the intake air flow and the crank angle of the crank shaft of the engine, and further corrects the timing according to the air fuel ratio difference between cylinders whose intake strokes are adjacent to each other. The correction rate of the timing may be changed according to the degree of the engine load and/or the engine temperature. By the correction of the timing, the air fuel mixture in rich cylinders is partly inhaled into lean cylinders so that the air fuel ratios of the cylinders may be equalized.

摘要： An internal combustion engine is provided with an exhaust gas recirculating passage for communicating the intake passage and the exhaust passage thereof. The recirculating passage is provided with a valve for controlling the amount of recirculated exhaust gas. A fundamental air-fuel ratio control value for regulating the air-fuel ratio of the intake gas to a predetermined value is corrected by an operating condition correction value according to the operating condition of the engine. The operating condition correction value is successively changed to an optimal value by comparing the actually obtained air-fuel ratio with a predetermined value. The operating condition correction value for correcting the fundamental air-fuel ratio control value when the exhaust gas recirculation is carried out is changed independently from the same for correcting the fundamental air-fuel ratio correction value when the exhaust gas recirculation is not carried out. The initial values of the former correction value and the latter correction value are compared with each other, while the present values of the former correction value and the latter correction value are compared with each other. The comparison value of the initial values and the comparison value of the present values are compared with each other to detect clogging of the recirculating passage. When clogging is detected, the valve is controlled to compensate for the clogging.
