The invention relates to a catalytic converter for treating exhaust gases of an internal combustion engine, having a housing through which an exhaust gas may flow and which has an inflow side and an outflow side, wherein, in the housing, there is formed a plurality of flow channels (4, 13) which is flowed through along a main throughflow direction from the inflow side to the outflow side, wherein, in the housing, there is arranged at least one pipeline (5, 12) which is flowed through by a fluid which is independent of the exhaust gas that is caused to flow through the flow channels (4, 13).

An exhaust system for an internal combustion engine, especially diesel internal combustion engine, includes an exhaust gas flow duct (12). At least one exhaust gas treatment unit (23, 26, 28, 30) is provided in an exhaust gas treatment duct area (16) of the exhaust gas flow duct (12). The exhaust gas treatment duct area (16) of the exhaust gas flow duct (12) extends, in at least some areas, in an insulation volume (20), through which exhaust gas discharged from the exhaust gas treatment duct area (16) can flow.

A pulse exhaust pipe for use with diesel engines an end of the pulse exhaust pipe is in communication with eight cylinders, and another end is in communication with two turbochargers; the pulse exhaust pipe includes three exhaust pipe sections which are separated from each other, each exhaust pipe section discharging to a turbocharger independently, wherein a first exhaust pipe section is in communication with a first and second cylinder, while a second exhaust pipe section is in communication with a third to a sixth cylinder, and a third exhaust pipe section is in communication with a seventh and eighth cylinder. The pulse exhaust pipe may prevent the backward flow of exhaust gas and inlet air back flow, thus increasing inflation efficiency and improving the uniformity of each cylinder. Also provided is a diesel engine installed with said pulse exhaust pipe.
