Document Type and Number:
Japanese Patent JP4462361
Kind Code:
B2
Abstract:
An exhaust gas purification device has: a bypass passage (20) disposed in an exhaust passage (15) of an internal combustion engine (10); an adsorbent (21) which is disposed in the bypass passage (20), and adsorbs unburned components in exhaust gas at a low temperature and desorbs the adsorbed unburned components at a high temperature; and an exhaust gas purification catalyst (22) which is disposed in the exhaust passage (15) at a downstream side of a portion where the bypass passage (20) merges, and purifies unburned components in exhaust gas; and a desorption amount adjustment (19) unit that adjusts the desorption amount of unburned components adsorbed by the adsorbent (21) based on an integrated fuel cut air amount (fgs), which is an integrated value of air amount taken into a combustion chamber of the internal combustion engine (10) during execution of fuel cut.
