Abstract:
1. A supercharged internal combustion engine of a motor vehicle, comprising: a cooling circuit, wherein a working medium is circulated in the cooling circuit, wherein the working medium is conveyed in both a liquid and a vaporous or gaseous physical state; at least one expander unit operatively connected with an output shaft of the internal combustion engine via a power train, in which through a conversion of energy contained in the at least partially vaporous or gaseous working medium, an output shaft of the expander unit is moveable, wherein the expander unit is embodied as a two-cycle reciprocating engine, which is operatively connected directly or indirectly via the power train with the output shaft of the internal combustion engine; and a fan wheel having a fan drive shaft, wherein said fan wheel and said two-cycle reciprocating engine are configured to operate independently from one another; a clutch configured to selectively couple and decouple the fan drive shaft and a crankshaft of said two-cycle reciprocating engine; wherein the two-cycle reciprocating engine is disposed in a region located between the internal combustion engine and the fan wheel.
