  • Patent number: 8464517
    Abstract: Method to reduce NOx contained in an exhaust gas by including an oxidation catalyst device and a selective reduction type NOx catalyst device, which are arranged in this order from an upstream side, and a NOx purification system. Whether a volume of NO2 adsorbed in the oxidation catalyst device increases or decreases is estimated, and a flow rate of exhaust gas which bypasses the oxidation catalyst device on a basis of the increase or decrease in the estimated volume of adsorbed NO2 is controlled. This avoids incorrect supply of ammonia.
