Abstract
In an emission control system, an absorbent in an exhaust-emission passage absorbs a particular component in the emission with a temperature thereof being lower than a first temperature, and desorbs therefrom the absorbed particular component with the temperature thereof being equal to or higher than the first temperature. A catalyst in the exhaust-emission passage converts the particular component desorbed from the absorbent into another component with a temperature thereof being equal to or higher than a second temperature higher than the first temperature. A heat recovery device is disposed in the exhaust-emission passage upstream of the absorbent and recovers heat from the exhaust emission by heat exchange between a heat-transfer medium and the exhaust emission. An adjusting unit adjusts an amount of heat to be recovered by the heat recovery device to thereby adjust a temperature state of the exhaust emission.
