Abstract
An exhaust gas turbocharger for an internal-combustion engine has a turbine housing and compressor housing in which a turbine wheel and a compressor impeller are connected with one another shaft. The turbine housing has a spirally-extending inlet duct for the exhaust gases. Devices for the flow deflection can be provided in the inlet duct. As a result, the thermal stress as well as the efficiency of an exhaust gas turbocharger with a spirally extending inlet duct for the exhaust gases are improved.
Claims9
An exhaust gas turbocharger for an internal-combustion engine, comprising a turbine housing, a compressor housing, a turbine wheel operatively arranged in the turbine housing, and a compressor impeller operatively arranged in the compressor housing and operatively connected with the turbine wheel by a shaft, the turbine housing having a spirally extending inlet duct for the exhaust gases, wherein at least one device is operatively arranged in the inlet duct to effect flow deflection.
An exhaust gas turbocharger, comprising a turbine housing, a compressor housing, a turbine wheel operatively arranged in the turbine housing, and a compressor impeller operatively arranged in the compressor housing and operatively connected with the turbine wheel by a shaft, the turbine housing having a spirally extending inlet duct for the exhaust gases, and means in the inlet duct for effecting flow deflection to minimize flow losses in the inlet duct and improve overall efficiency of the turbocharger.
In an internal combustion engine exhaust gas turbocharger having a spirally extending inlet duct, the improvement comprising a device provided in the inlet duct for causing flow deflection.
