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 intake system utilizing an air-fuel control which is changed in accordance with the coolant temperature. When the coolant temperature is lower than the first coolant temperature, an open loop control is carried out in accordance with the coolant temperature so that a fluctuation of the air-fuel ratio can be restricted so as to obtain a stability. An air-fuel feedback control is carried out between the first and second coolant temperatures wherein the air-fuel ratio is maintained at the stoichiometric value so that an increase of NO.sub.X emitted from the engine can be suppressed. In the region in which the coolant temperature exceeds the second temperature, an air-fuel feedback control is carried out in the lean mixture side of the stoichiometric value in accordance with the coolant temperature to thereby improve the emission performance of the engine.
