Abstract

In an engine braking arrangement for an internal combustion engine with an exhaust gas turbocharger including a turbine arranged in the engine exhaust duct and a compressor driven by the turbine and arranged in the engine intake duct, a brake valve disposed in the exhaust duct upstream of the turbine and a pressure relief line extending from the exhaust duct upstream of the turbine rotor to an area downstream of the turbine and including a stop valve, the stop valve is a rotationally adjustable rotary valve operable by an actuating device depending on the intake pressure in the intake duct.
