4.2.4 Checks when starting up the engine
u Measure speed, oil pressure and charging pressure at various engine performances.
u
Measure the exhaust gas temperature before and after the turbine.
u
Measure the air temperature before and after the compressor.
u
Compare the measured values with the values of the acceptance report. Different operat-
ing conditions indicate a malfunction (see Chapter
Troubleshooting → 70 ).
Escape of oily fluids
Lubricants and pastes used during assembly can liquefy or vaporise and escape as oily fluids
during the initial hours of operation. Continual escape of an oily fluid indicates an oil leak.
u
If there is a leak, contact an ABB Turbocharging Service Station.
