Abstract
The invention relates to a motor vehicle with an internal-combustion engine, with a heatable payload space and with a pipe flowed by air and leading into the atmosphere, which is divided into two pipe branches. A first heat exchanger flowed by the waste gases of the internal combustion engine is arranged in one of these pipe branches, while a second heat exchanger is arranged in the pipe downstream of the conjunction of the two pipe branches. The latter heat exchanger is flowed on the secondary side by a liquid serving to cool the internal-combustion engine, so that waste gas heat can be transmitted to this liquid, or cooling heat can be discharged to the exterior, as a function of heat incidence and heat demand. In certain embodiments, two heat exchangers are arranged in series in the pipe leading to the atmosphere, one operatively interposed in the engine cooling water circuit, the other operatively interposed in the engine cooling oil circuit.
