    摘要： An exhaust gas turbocharger for an internal combustion engine, which has an exhaust gas turbine in the exhaust system and a compressor in the induction system, comprises a variable turbine geometry, associated with the turbine, for adjustably setting a radial inlet cross section for the flow to the turbine rotor. The variable turbine geometry is configured as a guide cascade ring, which has guide vanes distributed over the periphery and encompasses the turbine rotor. The minimum distance between two adjacent guide vanes obeys a specified relationship with respect to the diameter of the turbine rotor and the number of guide vanes of the guide cascade ring. In addition, a flow edge is provided on the radially inner surface of each guide vane.

    摘要： An engine brake for a supercharged internal combustion engine for driving a motor vehicle is operated such that the working gas compressed during engine braking, prior to the end of the expansion cycle, is drawn at least partially from the working chambers of the engine through at least one throttle valve, with an exhaust turbocharger of the engine having an exhaust turbine with variable turbine geometry. The engine braking power is regulated based upon the travel of the throttle valve and/or an intake cross section of the exhaust turbine as a function of the operating parameters of the internal combustion engine and the vehicle driving speed. Upon issuance of a signal indicating a braking performance requirement from the driver, the required braking power is applied at least preferably through the engine brake.

    摘要： In a turbocharger system for internal combustion engines, the internal combustion engine has at least one combustion chamber with a variable volume and a swept volume determined by the sum of the differential volumes between the smallest and largest volumes of the combustion chambers of the internal combustion engine. The turbocharger system associated to the internal combustion engine has at least one turbine arranged in the exhaust gas pipe of the internal combustion engine and provided with a flow channel which opens via an annular jet-shaped region onto a turbine wheel. A guiding apparatus arranged in the opening region of the flow channel has a variable guiding grid with adjustable guiding blades which make it possible to obtain free flow sections of different sizes and which acts as a throttle during braking in an adjustable manner, depending on the operational parameters of the internal combustion engine, for determining the narrowest flow section in the exhaust gas pipe that leads to the turbine. The system is characterized in that at maximum braking power the relation between the free flow section A in the exhaust gas pipe that leads to the turbine, the inlet diameter D of the turbine wheel and the swept volume VH of the internal combustion engine is described by the equation (I) when the braking power supplied by the internal combustion engine during braking is at its maximum, the turbo-braking factor (TBF) being smaller than 0.0005 (5%). The internal combustion engine and the turbocharger are matched so as to supply maximum braking power with low thermal stress.
