Patent ID: 8661792

Claim:
An automobile exhaust line comprising: upstream and downstream blocks for processing exhaust gases flowing in the exhaust line, the upstream and downstream blocks being arranged in series in the exhaust line; an injection section arranged between an upstream face defined by the upstream block and a downstream face defined by the downstream block and including a circulation channel for exhaust gas flow extending from the upstream face to the downstream face, the circulation channel including a central line having a determined length between the upstream and downstream faces, the injection section including a reagent injector mounted on the injection section and capable of injecting a reagent into the injection section; the injection section comprises at least a first cup arranged inside the circulation channel in the path of the exhaust gas flow such that an average path of exhaust gas jets is higher by at least 20% in relation to the determined length; wherein the injection section comprises a second cup arranged inside the circulation channel between the upstream face and the first cup; and wherein the injection of the reagent is done between the first cup and the second cup.
