Apparatus for controlling the amount of secondary air fed into an internal combustion engine |
摘要 |
Disclosed is an apparatus for controlling the amount of secondary air fed into an internal combustion engine. This apparatus includes means for causing a sudden change of the level of the absolute pressure signal for driving the secondary air flow control means each time the level of the output voltage of the air-fuel ratio sensor changes. Thus, the equivalent air-fuel ratio is maintained for a long time within a desired range so that the highest purifying efficiency of the three-way catalytic converter can be attained.
