Abstract
A reducing agent supplying device includes a reaction container, an ozone generator, an air pump, an ozone-containing air pipe, a compressed air pipe, a switching device, and a switching controller. The reaction container defines a reaction chamber therein in which a reducing agent is reformed. The ozone generator generates ozone from oxygen in air. The air pump supplies air into the ozone generator. An ozone-containing air flows through the ozone-containing air pipe toward the reaction chamber. A portion of a compressed air flows through the compressed air pipe toward the reaction chamber. The switching device switches between an air pump mode, in which the ozone-containing air is supplied into the reaction chamber, and a supercharging mode, in which the compressed air is supplied into the reaction chamber. The switching controller controls the switching device based on a catalyst temperature, which is a temperature of the reducing catalyst, and an exhaust pressure, which is a pressure in the exhaust passage.
