ABSTRACT:
A cylinder-piston internal combustion engine which includes at least two single or two two-stage exhaust gas turbochargers which together and in parallel supply the cylinder of the internal combustion engine with charging air when there is a large supply of exhaust gases from the internal combustion engine. When there is a small amount of exhaust gases available, at least one of the exhaust gas turbochargers is adapted to be switched off so as to increase the charging pressure. A check valve is disposed in a suction line of a compressor of the exhaust gas turbocharger which is adapted to be switched off with the check valve allowing a flow of air in a suction line of the compressor in a direction of the compressor but prevents a flow of air in an opposite direction.
