Title: CATALYST HEATING DEVICE
Abstract:
[Problem] To shorten the time to heat a catalyst without greatly increasing costs. [Solution] A catalyst heating device 1 heats a catalyst located in a vehicle exhaust passage 5, and includes: a water reservoir 2 that is provided to the lower surface of the exhaust passage 5 upstream of a purification catalyst 6; an electromagnetic-wave radiating device 3 that is located above the water reservoir 2, and radiates electromagnetic waves so as to heat water stored in the water reservoir 2 and generate steam; and a control device 4 that controls the electromagnetic-wave radiating device 3. The control device 4 controls the electromagnetic-wave radiating device 3 such that electromagnetic waves are radiated from the electromagnetic-wave radiating device 3 for a predetermined time when the vehicle is started or when shifting from a hybrid mode to an engine mode.
