Patent ID: 8479514

Claim:
A method for generating compressed air and blowing the compressed air into an internal combustion engine having an exhaust gas turbocharger, comprising the acts of: determining an operating state of the internal combustion engine from at least one operating parameter of the internal combustion engine; generating compressed air by the internal combustion engine when it is determined that the operating state is an operating state without combustion in at least one cylinder of the internal combustion engine in which fuel is selectively supplied for combustion; storing the generated compressed air; and blowing of the stored compressed air into the internal combustion engine when it is determined that the operating state is a combustion operating state of the internal combustion engine, wherein the compressed air is generated by the at least one cylinder of the internal combustion engine, the generated compressed air passes through an exhaust port of the at least one cylinder into an exhaust manifold of the internal combustion engine upstream of the exhaust gas turbocharger, the generated compressed air is routed from the exhaust manifold and stored in a compressed air vessel via at least one controlled valve between the at least one cylinder and the compressed air vessel, and the stored compressed air is blown into the internal combustion engine by controlled switching on of a blowing-in valve between the compressed air vessel and the internal combustion engine.
