  • Exhaust gas purification device
    Patent number: 8161734
    Abstract: An exhaust gas purification device includes an exhaust pipe defining an exhaust passage, a first SOX adsorption portion having a first SOX adsorption material provided in the exhaust passage, a second SOX adsorption portion having a second SOX adsorption material provided in the exhaust passage, and a NOX catalyst provided downstream of the first SOX adsorption portion and the second SOX adsorption portion in the exhaust passage. The first SOX adsorption material is configured to adsorb SOX in the combustion gas at a temperature lower than a first set temperature. The second SOX adsorption material is configured to store SOX in the combustion gas at a temperature equal to or higher than a second set temperature, and the stored SOX can be kept at a temperature lower than the second set temperature. Therefore, the exhaust gas purification device can adsorb SOX in the exhaust gas with high efficiency.
