engine braking method for a pressure-charged combustion engine and device for modulating the engine braking power of a motor vehicle having a pressure-charged combustion engine

摘要

The invention relates to an engine braking method for a pressure charged combustion engine having an exhaust turbocharger. The invention further relates to a device for modulating the engine braking power of a motor vehicle having a pressure charged combustion engine. According to the invention, the exhaust turbocharger is an electric motor assisted exhaust turbocharger, wherein the desired or required engine braking power configuration is completed by accelerating an electric motor operation exhaust turbocharger rotor (s4). ) of the exhaust turbocharger and / or by braking the rotor 11, 12, 13 by operating the exhaust turbocharger generator type (s5).
