Abstract
An exhaust purification catalyst warm-up system has an air pump that supplies air upstream from an exhaust purifying catalyst, disposed in an exhaust pipe of an internal combustion engine, the pump supplying air when the exhaust purifying catalyst is being warmed up. The exhaust purification catalyst warm-up system also has an atmospheric pressure sensor that detects the atmospheric pressure, wherein correction is performed so that the degree of fuel increase is smaller, the higher is the atmospheric pressure detected by the atmospheric pressure sensor.
