Abstract:
An engine (1) with an exhaust passage (2) in which a catalyst (3) purifying NO x and an NO x adsorbent (4) adsorbing NO x in an exhaust gas are arranged successively from the upstream side. After engine startup until the catalyst (3) is activated, the NO x in the exhaust gas is adsorbed at the NO x adsorbent (4). NO x adsorbed at the NO x adsorbent (4) is removed by dissolution by supplying a solvent from an injector (7). After the catalyst (3) is activated, the solvent containing the NO x removed by dissolution is sprayed from an injector (11) and the NO x contained in the sprayed solvent is purified by the catalyst (3).
