Titre
(EN) Turbocompressor system for an internal combustion engine
(ZH) 用于内燃机的涡轮压缩机系统
Abrégé
(EN)
The invention relates to a turbocharger unit (18) for an internal combustion engine (10) with at least one exhaust line (15, 16) for conducting exhaust gases away from the combustion chamber (11) of the engine and at least one inlet line (12) for supplying air to said combustion chamber. The turbocharger unit comprises a turbine (17) which interacts with a compressor (19) for extracting energy from the exhaust gas flow of the engine and pressurizing the inlet air of the engine. The compressor (19) is of radial type and provided with an impeller with backswept blades (35) where the blade angle (betab2) between an imaginary extension of the center line of the blade between root section and tip section in the direction of the outlet tangent and a line (36) which connects the center axis of the impeller to the outer tip of the blade is at least roughly 45 DEG . The turbine (17) which drives the compressor (19) is of radial type.
