Exhaust turbosupercharger for internal combustion engine has comparison volume of turbine rotor in defined relation to output diameter of compressor rotor

摘要

The turbosupercharger has a running part (1) and a housing (2). The running part includes a turbine rotor (3) made of a titanium-aluminum alloy. The comparison volume (VT) of the turbine rotor is in a defined relation to the output diameter (D2V) of the compressor rotor. This output diameter should preferably be less than 70 mm.
