    • An intake secondary air supply system for adding air to the intake of an internal combustion engine under certain sensed conditions, such as an excessively rich air-fuel ratio detected by an oxygen sensor in the exhaust system, wherein two separate secondary air supply passages are provided and separately controlled by vacuum responsive valves. One of such valves is controlled to open and close over a period of time to provide a changing supply of secondary air while the other valve is connected through a solenoid operated valve to the engine intake to provide an immmediate opening or closing of that secondary air supply. Vacuum controls responsive to engine operating condition serve to operate the vacuum responsive valves although in one embodiment one of such valves is operated by a constant regulated vacuum.

    • A secondary air intake system is used in an internal combustion engine. The system supplies secondary air through a first and a second secondary air passage. The first secondary air passage includes a first vacuum operated air control valve. The second secondary air passage includes a second vacuum operated air control valve and an electrically operated air control valve positioned in series. A vacuum control which includes an electrically operated vacuum control valve operates the first and second vacuum operated air control valves to vary the effective area of the two air passages.
