EXHAUST PURIFIER FOR INTERNAL-COMBUSTION ENGINE |
摘要 |
<p>In an exhaust passage in an internal-combustion engine in which combustion occurs with excessive oxygen, an upstream particulate filter (24u) and a downstream particulate filter (24d) are disposed in series in order to capture particulate matter included in an exhaust gas. The upstream particulate filter and the downstream particulate filter hold an upstream catalyst and a downstream catalyst having an oxidation function, respectively. The downstream catalyst is set to have a higher oxidization capability for particulate matter than the upstream catalyst.</p> |
