Abstract

The disclosure relates to a carrier housing for an internal combustion engine having an engine block with a V arrangement of cylinders and having a charging group, designed for two-stage charging. The carrier housing is designed to bear at least a number of components of the charging group, and is designed to be arranged on an upper face of the engine block in an intermediate space of the V arrangement. The carrier housing includes a bottom fastening mechanism for attaching the carrier housing to the upper face of the engine block, a charge air channel formed in the interior of the carrier housing for conducting the charge air of a high-pressure and/or low-pressure stage of the charging group, a cooling fluid channel formed in an interior of the carrier housing for conducting the cooling fluid of an exhaust gas recirculation of the charging group, a channel for coolant and a channel for lubricant formed in the interior of the carrier housing for the high-pressure and/or low-pressure stage of the charging group, and upper carrying elements for components of at least the high-pressure and/or low-pressure stage of the charging group.
