Abstract
A reciprocating internal combustion engine with supercharging by several exhaust gas turbochargers. One or more housings are arranged on the internal combustion engine with the exhaust gas turbochargers being adapted to be mounted in the walls of such housing or housings in such a way that the turbines of the exhaust gas turbochargers and exhaust gas conduits are located in an interior of the housing or housings; whereas, the compressors of the exhaust gas turbochargers, as well as the supercharger air conduits with the supercharger air coolers are located exteriorly of the housing or housings.
