Cartridge concept
Fig.41: Cartridge concept
The cartridge concept incorporates the removal and installation of the turbocharger from/
onto the engine, whereby the air inlet (filter silencer or air suction branch), the compressor
casing and the cartridge group can be individually dismantled and fitted in the order shown
in the illustration.
The turbine casing and optional gas outlet casing remain on the engine during the process.
In addition, the nozzle ring can also be dismantled/fitted with this concept (not shown).
When employing the cartridge concept, the turbine casing and the optional gas outlet cas-
ing remain on the engine. Adequate support or suspension of these components must be
ensured.
A prerequisite is that the interfaces between the cartridge group and the turbine casing, as
well as between the cartridge group and the compressor casing, are accessible at the engine
side.
