| 摘要 |
<p>The invention relates to an exhaust line (2) for an automobile, that includes: two upstream (14) and downstream (16) blocks for processing the exhaust gases flowing in the exhaust line (2), the two upstream (14) and downstream (16) blocks being arranged in series in the exhaust line (2); an injection section (18) arranged between an upstream face (20) defined by the upstream block (14) and a downstream face (22) defined by the downstream block (16) and including a circulation channel (24) for the exhaust gas flow extending from the upstream face (20) to the downstream face (22), the channel (24) including a central line (L1) having a determined length between the upstream (20) and downstream (22) faces, the injection section (18) comprising a reagent injector (26) mounted on the injection section (18) and capable of injecting a reagent into the injection section. The injection section (18) comprises at least a first cup (30) arranged inside the circulation channel (24) in the path of the exhaust gas flow such that the average path of the exhaust gas jets is higher by at least 20% in relation to the predetermined length.</p> |
