Mode of operation
The turbocharger is a turbomachine consisting of two main components, a turbine and a
compressor. These components are mounted on a common shaft and form the rotor.
In the turbocharger shown in the illustration, the exhaust gas flows through the gas inlet
casing(06) and the nozzle ring(07) and arrives at the turbine(08). The turbine utilises the
energy contained in the exhaust gas to drive the rotor. The exhaust gases then escape into
the open air through the gas outlet casing(05) and the exhaust gas pipe connected to it.
The rotor runs in two radial plain bearings, which are located between the compressor and
the turbine in the bearing bush(04). The axial bearing is also a plain bearing. The plain bear-
ings are connected to a central lubricating oil duct which is normally supplied by the lubric-
ating oil circuit of the engine. The oil outlet is situated at the lowest point of the bearing
casing(09).
The compressor wheel(02) connected to the shaft draws in fresh air through the filter silen-
cer(01) or the air suction branch. The air is compressed in the compressor and the down-
stream diffuser(03) and then led to the charge air cooler via the compressor casing(10).
Turbocharger version with compressor wheel cooling
Fig.3: Connection of the compressor wheel cooling
Depending on the application, the turbocharger is equipped with compressor wheel cooling.
With compressor wheel cooling, after the compressor air has cooled down by passing
through the charge air cooler on the engine side, it is supplied to the turbocharger for cool-
ing the compressor wheel.
Cooling of the compressor wheel is compulsory to ensure the reliability and replacement in-
tervals for the relevant operating conditions. In the turbocharger version with compressor
wheel cooling, the cooling air is supplied through the lateral connection (15) in the bearing
casing.

2.5 Intended use
Use on internal combustion engines in general
ABB turbochargers are intended for charging internal combustion engines.
To ensure compliance with the machinery directive 2006/42/EC when using on gas engines,
the turbocharger must be operated in an engine room classified as "not at risk of explosion".
This is in accordance with the position paper [2] relating to ATEX issued by EUROMOT[1].
The turbocharger supplies the engine with the air volume or air/gas mixture and the associ-
ated charging pressure required for operation.
The turbocharger is solely intended to be operated with a clockwise direction of rotation as
viewed from the turbine end.
The specific operating limits of the turbocharger were determined on the basis of informa-
tion from the enginebuilder about the intended use. These data are given on the rating
plate.
ABB accepts no liability and rejects all warranty claims for any non-intended uses.

© Copyright 2020 ABB. All rights reserved. HZTL4033_EN Rev.G December 2020
ABB excludes any liability for damage resulting from unauthorized modifications to the tur-
bocharger or improper operation.
2.6 Deflagration on gas engines
ABB turbochargers can tolerate a deflagration with a transient pressure increase of 12bar.
After a deflagration event ABB recommends verifying the following points on the turbochar-
ger:
¡Position of the turbine and compressor casings to the bearing casing
¡Shifting of the bearing casing in relation to the bracket
¡Cracks in casings
If during external inspection anomalies are found or if a particularly strong deflagration
event has taken place, it is also recommended to check the bearings of the turbochargers
before the next start. An ABB Turbocharging Service Station should be instructed to carry
out this inspection.
2.7 Periodic check of the pressure vessels
The pressure vessels used by ABB Turbocharging, such as those for wet or dry cleaning, are
so-called "simple pressure vessels".
¡The locally applicable legal regulations regarding periodic checks of the pressure vessels
must be observed.
¡The operating company is responsible for the safe operation of the pressure vessel.
WARNING
Danger due to pressure vessels
The operating company must make sure the pressure vessels are in proper
working condition and monitor them. Necessary repair or maintenance work

2 Safety / 2.9 Turbocharger rating plate
© Copyright 2020 ABB. All rights reserved. HZTL4033_EN Rev.G December 2020
Explanations regarding the rating plate
The recommended replacement intervals and the corresponding operating limits are jointly
defined with the enginebuilder. This information is specific to the system.
Operation above the indicated values nBmax, tBmax can considerably shorten the recommended
replacement intervals. In such cases ABB recommends contacting the nearest ABB Tur-
bocharging Service Station.
nMmax, tMmax normally apply only when running at overload (110%) during trials on the engine
test bed. These limit values can also be permitted during operation for special applications.
Operation above nMmax and tMmax is not permitted.
Non-observance of the recommended replacement intervals increases the risk of unpredict-
able component failures.
Locations of the rating plates
Fig.8: Locations of the rating plates
One rating plate (01) each is attached on the left and the right side of the foot of the tur-
bocharger.
On turbochargers with insulation supplied by ABB, at least one additional rating plate is at-
tached to the insulation of the gas outlet casing.
