Ensure supply of cooling air.
3.2.2
Check after start-up (engine at idling speed)
Lubricating system
u
Check oil pressure in oil supply lines.
u
Check oil inlet temperature.
The permissible values are listed in the section Oil supply.
Gas, air and oil lines
u
Check all gas, air and oil lines for leaks after starting the engine.
3.2.3
Check when running up engine
u
Measure speed, oil pressure and charging pressure at various engine
performance levels.
u
Measure exhaust gas temperature in front of and behind turbine.
u
Measure air temperature in front of and behind compressor.
The measured values must be compared with the values in the accept-
ance test report, while taking different operating conditions into ac-
count.
NOTICE
Lubricants and pastes used during assembly of the turbocharger li-
quefy 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, an oil leak must be suspected. The first step is to check for leak-
age of the oil supply to the turbocharger. If this is leaky, contact an offi-
cial ABB Turbocharging service station.
3.2.4
Inspection after 100 service hours
Clean or replace lubricating oil filters after the first 100 service hours.
