| 摘要 |
<p>The present invention relates to an arrangement for counteracting cooling of an exhaust treating component in a vehicle. The arrangement comprises a brake system (11) which itself comprises a braking component in the form of a retarder (11a) connected to the vehicle's powertrain, and a first line (11c) adapted to leading a liquid medium to the retarder (11a) in operating situations where the retarder (11a) is activated. The brake system (11) comprises a first heat exchanger (11f) for cooling the liquid medium, situated in the exhaust line (2) at a point between the engine (1) and the exhaust treating component (6), and a second line (11e) adapted to receiving warm liquid medium from the retarder (11a) and leading it to the first heat exchanger (11f) in operating situations where the retarder (11a) is activated.</p> |
