Turbocharger unit for an internal combustion engine

摘要

The invention relates to a turbocharger unit (18) for a multicylinder internal combustion engine having at least two exhaust lines' for the evacuation of exhaust gases from the combustion chamber of the engine and at least one inlet line for the supply of air to said combustion chamber. The turbocharger unit comprises at least one turbine (17), which cooperates with at least one compressor (19) to extract energy from the exhaust flow of the engine and pressurize the inlet air of the engine. The turbine is provided with a worm-shaped housing having at least two flow paths (15, 16) which are defined by means of guide tongues (35) in the housing and which conduct mutually separate exhaust flows via stator blades (34) to at least one turbine wheel (17, 23) . In order to maintain the kinetic energy in the separate exhaust flows, each respective guide tongue (35) meets a stator blade (37) extended toward the tongue.
