    • There is provided a device for supplying secondary air, which comprises a secondary air passage for supplying secondary air, to an exhaust passage of an engine, upstream of an exhaust purification device provided in the exhaust passage, a pump provided in the secondary air passage for supplying a secondary air, a battery used for driving the pump, at least one opening-closing device for opening and closing the secondary air passage, and a pressure sensor provided between the pump and the opening-closing device for detecting a pressure in the secondary air passage. A malfunction of at least one of the pump and the opening-closing device is detected on the basis of at least one of the pressures detected when the secondary air passage is opens and when the secondary air passage is closed. The malfunction detection is ceased when the voltage of the battery changes by a value larger than a predetermined value when the pressure sensor detects a malfunction of the pressure variation in the secondary air passage for detecting a malfunction of at least one of the pump and the opening-closing device.

    • A catalyst overheat prevention apparatus has a temperature obtaining portion that estimates a convergence temperature of a catalyst provided in the exhaust system of an internal combustion engine and the present temperature of the catalyst. The catalyst overheat prevention apparatus also has a fuel increment calculation portion, a comparison portion, a correction portion, and a fuel increment setting portion, which are used to execute OT fuel increase control when the convergence temperature and present catalyst temperature obtained by the temperature obtaining portion are equal to or higher than an OT determination temperature. The catalyst overheat prevention apparatus also has a present temperature correction portion that corrects the present catalyst temperature to be equal to the OT determination temperature when the present catalyst temperature is equal to or higher than the OT determination temperature and the convergence temperature is equal to the OT determination temperature.
