Abstract
The invention relates to an exhaust gas turbine, comprising a turbine wheel () with a multiplicity of moving blades () and an exhaust-gas outlet duct (), which is arranged downstream of the moving blades of the turbine wheel. The exhaust-gas outlet duct () is delimited radially on the outside by an axial turbine diffuser () and radially on the inside, at least partially, by a spinner (). The axial turbine diffuser () is formed by a number N>1 of successive conical diffuser segments. An axial diffuser opening angle A between successive diffuser segments is A>1.0°. A ratio L/H between an axial diffuser segment length L and an entry height H of the exhaust-gas outlet duct () is L/H>0.01. A ratio H/S between the entry height H of the exhaust-gas outlet duct and a maximum radius S of the spinner () is H/S>1.0. The spinner () is formed by a number P>1 of successive conical spinner segments. An axial spinner opening angle B between successive spinner segments is B>1.0°. A ratio M/H between an axial spinner segment length M and the entry height H of the exhaust-gas outlet duct () is M/H>0.01.
