An exhaust gas purification device for a compression-ignition combustion engine |
摘要 |
<p>An exhaust gas purification device of a compression-ignition combustion engine comprises exhaust branch passages (22-25) each being connected to a corresponding cylinder (10d) of the engine at one end thereof and connected to a common exhaust passage (21) at the other end thereof, and a filter (42-45) arranged in at least one of the exhaust branch passages (22-25) to trap particulates in the exhaust gas discharged from the engine. Pressure in the exhaust branch passage upstream of the filter is controlled to continuously make the pressure equal to or greater than a pressure in the exhaust branch passage downstream of the filter. <IMAGE></p> |
