摘要： Method for controlling the braking effect during engine braking in an internal combustion engine (10) having an exhaust turbocharger unit (16) with adjustable guide blades for controlling the turbine speed and gas flow. The method includes detection of the engine speed, detection of the adjustment position of the guide blades, measurement either of the charging pressure on the intake side of the engine or the manifold pressure on the exhaust side of the engine, comparison of these data with stored desired values, and adjustment of the guide blades to a desired position which gives a suitable braking effect for the prevailing charging pressure.

摘要： Method and arrangement for a turbocompound type internal combustion engine including an exhaust system for ducting the engine's exhaust gases. A supercharger turbine drives a compressor for the engine's combustion air, and an exhaust turbine is placed in the exhaust system downstream of the supercharger turbine for extracting residual energy from the exhaust flow via transmission to the combustion engine's crankshaft. The exhaust system also has an exhaust braking throttle placed downstream of the exhaust turbine. The exhaust braking throttle includes a pressure-controlled exhaust pressure regulator that makes possible variable regulation of an exhaust braking pressure in at least two steps.
