Zusammenfassung: | Modular system for multiple-stage supercharging devices which have, as exhaust gas-side assemblies, at least one high pressure turbine (11), a low pressure turbine (12) and an exhaust-gas outflow housing (13), and which have, as charge air-side assemblies, at least one high pressure compressor (20), a low pressure compressor (19) and a charge air cooler (27) which is connected between the low pressure compressor and the high pressure compressor, wherein a supercharging device can be assembled from a plurality of modules of the modular system, namely in such a way that: the charge air-side modules, namely at least the high pressure compressor (20) with the high pressure compressor rotor (24) and the high pressure compressor housing (26), the low pressure compressor (19) with the low pressure compressor rotor (21) and the low pressure compressor housing (23), and the charge air cooler (27) which is connected between the low pressure compressor and the high pressure compressor, are independent of the design of the exhaust gas-side modules; as exhaust gas-side modules, the high pressure turbine (11) with the high pressure turbine rotor (14) and the high pressure turbine housing (15) and the low pressure turbine (12) with the low pressure turbine rotor (16) and the low pressure turbine housing (17) are dependent on whether the high pressure turbine is configured as a radial turbine or as an axial turbine and the low pressure turbine is configured as a radial turbine or as an axial turbine; as exhaust gas-side modules, the high pressure turbine housing (15) and the low pressure turbine housing (17) are dependent on whether the supercharging device is configured without exhaust gas aftertreatment or with exhaust gas aftertreatment between the high pressure turbine and the low pressure turbine. An associated supercharging device is likewise presented. |
