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.
4.3 Commissioning after taking out of operation
If present
u Remove cover plates (blind flanges) from the compressor casing, the gas inlet and the
gas outlet.
General

ter residues and clean it. Remove any foreign objects that may be present.
u Check and clean filter silencer or air supply line, and remove any foreign objects that may
be present.
u Put engine-side oil circulation to the turbocharger into operation.
