    Abstract: An exhaust manifold for an internal combustion engine has at least one exhaust pipe and a flange which can be fastened to an engine block of the internal combustion engine. On the side facing away from the engine block, the flange is provided with a channel which is connected to a fluid line and which is in fluid communication with the interior of the exhaust pipe via a lateral opening in the exhaust pipe. The fluid line opens into the channel on the side of the flange that faces away from the engine block.

  • Internal-combustion engine including a cylinder shut-off and exhaust gas catalysts
    Patent number: 5647207
    Abstract: The two cylinder groups of an internal-combustion engine each have a separate exhaust gas catalyst. When one of these cylinder groups is shut off by preventing the supply of fuel, it is possible that the assigned exhaust gas catalyst may be cooled below its operating temperature. In order to avoid this, the whole exhaust gas system is constructed in such a manner that the gases emitted from the shut-off cylinder group are heated by the exhaust gases of the continuously fired cylinder group.
