Abstract
The invention relates to an engine braking device for a combustion engine in motor vehicles, which has an intake system, an exhaust system, gas exchange valves associated with the combustion engine, an exhaust turbocharger integrated into the exhaust system and the intake system, and an engine braking unit, wherein the engine braking unit has a decompression brake, which influences at least one outlet valve of the gas exchange valves, and a brake flap, which is arranged in the exhaust system and causes the exhaust gas to build up. The brake flap is arranged upstream of and outside, preferably directly upstream of and outside, a turbine housing of an exhaust turbine of the exhaust turbocharger and is designed as a flow guiding flap which influences the admission of a gas flow to the exhaust turbine. The invention also relates to a method for operating an engine braking device.
