<p>Method of increasing supercharge pressure at low full-load speed of an engine and for simultaneously limiting the supercharge pressure to a given value at high full-load speed of the engine, includes passing a flow of exhaust gas through a bladed rotor of an exhaust-gas turbine inwardly from the outside through respective entrances and exits of the rotor blades which, in the region of the entrances thereof, are disposed in a plane wherein the axis of the turbine is also disposed, so that a difference in a respective circumferential component of the velocity of the exhaust-gas flow between the blade entrance and the blade exit, taken with respect to the circumferential component of the exhaust-gas flow velocity at the blade entrance, is at least as great at low speeds of the engine as at higher speeds thereof.</p> |
