The method involves burning motor fuel i.e. propellant gas, in a combustion chamber of an internal combustion engine. The motor fuel is utilized before combustion, for cooling a compression device (2) i.e. radial exhaust gas turbo-charger. The compression device has a compressor housing (18) and a compressor wheel (17) arranged in the housing, where the motor fuel cools the wheel. The wheel has a flow surface (20), where the propellant gas to be compressed flows on the flow surface. The gas blows the wheel on a side (21) that lies opposite to the flow surface. An independent claim is also included for an internal combustion engine with a compression device. Verfahren zum Betreiben einer Brennkraftmaschine, wobei mit Luft (7) vermischter Treibstoff in zumindest einem Brennraum der Brennkraftmaschine verbrannt wird, wobei der Treibstoff vor der Verbrennung zur Kühlung einer Verdichtungseinrichtung (2) verwendet wird, wobei die Verdichtungseinrichtung (2) ein Verdichtergehäuse (18) und ein darin angeordnetes Verdichterlaufrad (17) aufweist, wobei der Treibstoff das Verdichterlaufrad (17) kühlt, wobei das Verdichterlaufrad (17) eine Anströmfläche (20) aufweist, auf die das zu verdichtende Gas anströmt, wobei das Treibgas das Verdichterlaufrad (17) auf der der Anströmfläche (20) gegenüberliegenden Seite (21) anströmt.
