Abstract
An exhaust gas purification apparatus for an internal combustion engine is capable of stably introducing secondary air and heating a catalyst at the same time without increasing an amount of discharge current from the battery. When the internal combustion engine 1 is started, the output terminal A of a generator 10 is electrically connected to the first contact 51 of a switching relay 50 through an output switching circuit 33 and the output terminal A of the generator 10 is electrically isolated from a second contact 52 . As a result, when the internal combustion engine 1 is started, since a current output from the generator 10 is supplied to the motor 8 of a secondary air introduction unit 6 and the heating element 3 of a catalytic converter 4, the power of a battery 20 is consumed only by a plurality of electric loads and is not consumed by the motor 8 and the heating element 3.
