1.6 Turbocharger rating plate

Operational limits
1.0  Turbocharger operational limits at engine overload (110 %). In test rig operation only, unless otherwise agreed with the engine manufacturer.
2.0  Turbocharger operational limits in service.

Recommended replacement periods / exchange intervals for turbocharger components
3.0  Replacement interval for the plain bearings in 1000 h
4.0  Exchange interval for the compressor in 1000 h (no data for 100,000 h)
5.0  Exchange interval for the turbine in 1000 h (no data for 100,000 h)

Additional specifications:
6 Customer part number
7 Field for special design designation
8 Weight of the turbocharger in kg
9 CE = Conformité Européenne
10 Turbocharger type
11 Series number
12 Year of construction of the turbocharger

Explanations of the rating plate
The recommended exchange intervals and the corresponding operation limits are defined together with the engine builder. These specifications are system-specific.


Work on mechanical components, such as bearings or rotors, must only be performed by qualified fitters from an official service station Continuous running above the indicated nBmax, tBmax values may considerably reduce the recommended exchange intervals. In such cases, we recommend you contact the nearest official service station of ABB Turbo Systems Ltd.
of ABB Turbo Systems Ltd.!

nMmax , tMmax normally apply only when running at overload (110 %) during trials on the engine test bed. These limits may also be permitted in service for special applications. The operation over nMmax , tMmax is not permitted.

Non-compliance with the recommended exchange intervals may increase the risk of unpredictable component failure.
