Original Operation Manual

Operating condition and replacement intervals
The operational limits for the turbocharger nBmax, tBmax, nMmax, tMmax, inspection- and replacement intervals for the compon-
ents concerned on the rating plate are valid for the operational mode and compressor inlet condition, which has been agreed upon
between the engine builder and ABB.
Note: Replacement intervals of components depends on the load profile, turbine inlet temperature, suction air temperature and
turbocharger speed. In case the operation conditions differs significantly from what is considered to be normal for the cur-
rent application, it is recommended to contact ABB for a re-calculation of replacement intervals. Frequent load alterations,
high temperatures and high speed lower the life of components.
Unless otherwise agreed, the application limits nMmax, tMmax are valid for the test operation for a limited time.

1 Preliminary remarks / 1.3 Intended use of the turbocharger
© Copyright 2018 . All rights reserved. HZTL2491_EN Revision C August 2018
Mode of operation
The turbocharger is a turbo-machine and consists of the following main
components:
¡Turbine
¡Compressor
These are both mounted on a common shaft.
Exhaust gases from the diesel engine flow through the gas inlet casing
(6) and the nozzle ring (7) to impinge on the turbine wheel (8).
The turbine wheel (8) uses the energy contained in the exhaust gas to
drive the compressor wheel (11). The compressor draws in fresh air, com-
presses it and then forces it into the engine cylinders.
The exhaust gas escapes to free air through the exhaust gas pipe which
is connected to the gas outlet casing (5).
The air, which is required for operation of the diesel engine and com-
pressed in the turbocharger, is drawn through the filter silencer (1) into
the compressor wheel (11). This air then passes through the diffuser (10)
and leaves the turbocharger through the compressor casing (12).
The rotor runs in two radial plain bearings (2/4), which are located in the
bearing casing (9) between the compressor and the turbine. The axial
thrust bearing (3) is at the compressor end.
The plain bearings are connected to a central lubricating oil duct which is
normally supplied by the lubricating oil circuit of the engine. The oil out-
let is always at the lowest point of the bearing casing (9).
The turbocharger is equipped with an emergency lubrication oil tank,
which is integrated in the bearing casing. During an emergency stop
caused by a failure of the lubrication oil system, this emergency lubrica-
tion unit supplies oil to the bearings until the rotor comes to a standstill.
1.3 Intended use of the turbocharger
This turbocharger supplied by ABB Turbo Systems has been developed
for use on diesel engines to generate the volume of air and the charging
pressure required to operate the engine.
The enginebuilder has provided ABB Turbo Systems with information re-
garding the intended purpose of use of the engine, from which the spe-
cific operating limits shown on the turbocharger rating plate (such as
speeds, temperatures and replacement intervals) have been determined.

1.7.1 Explanation of the rating plate
The recommended replacement intervals and the corresponding opera-
tional limits are jointly defined with the engine manufacturer. This in-
formation is specific to the system.
Operation above the indicated values nBmax, tBmax can considerably shorten
the recommended replacement intervals. In such cases, we recommend that
you contact the nearest official ABB Turbocharging service station.
nMmaxand tMmax normally apply only when running at overload (110%) during
trials on the engine test bed. Operation above nMmax and tMmax is not permit-
ted.
Non-observance of the recommended replacement intervals increases the
risk of unpredictable component failures.
1.7.2 Positions of the rating plates
A rating plate is attached to the turbocharger foot, one on the left and
one on the right. On turbochargers with insulation from ABB, at least one
additional rating plate is attached to the insulation of the gas outlet cas-
ing.
