ABSTRACT:
A secondary air supply system includes an exhaust gas control catalyst which is provided in an exhaust system in an internal combustion engine, and which purifies a harmful component in exhaust gas; a secondary air supply device which supplies secondary air into the exhaust gas upstream of the exhaust gas control catalyst; a secondary air supply stop device which stops the secondary air supply performed by the secondary air supply device; a fuel supply device which supplies fuel to the internal combustion engine; a fuel amount increasing device which increases a fuel amount supplied to the internal combustion engine during the secondary air supply; and a fuel amount increase stop time delaying device which delays, by a predetermined delay period, a stop time at which the increase in the fuel amount caused by the fuel amount increasing device is stopped even when the secondary air supply is stopped.
