Commissioning
Inspection work
Check after start-up (engine at idling speed)
Lubricating system
Check oil pressure in oil supply lines.
Check oil inlet temperature.
The permissible values are listed in the section Oil supply.
Gas, air and oil lines
Check all gas, air and oil lines for leaks after starting the engine.
Check when running up engine
Measure the speed, oil pressure and charging pressure at various en-
gine performance levels.
Measure the exhaust gas temperature in front of and behind the tur-
bine.
Measure the air temperature in front of and behind the compressor.
Check the functioning of the variable turbine geometry module.
The measured values must be compared with the values in the ac-
ceptance test report while taking different operating conditions into ac-
count.
Lubricants and pastes used during assembly of the turbocharger liquefy
or vaporise and might escape as an oily liquid in the first few hours after
commissioning. If oily liquid continues to escape after this period, the
operator is to search for the cause of a possible oil leak. The first step is
to check the seal for the oil supply to the turbocharger. If this is not in
proper condition, contact an official ABB Turbocharging service station.
Inspection after 100 service hours
Clean or replace lubricating oil filters after the first 100 service hours.
