4.2.3 Checks after commissioning (engine in idle mode)
Lubricating system
u Observe lubricating oil pressure at inlet upstream of turbocharger.
u Observe lubricating oil temperature at inlet upstream of turbocharger.
u For permissible values, see chapter Monitoring operation →45.
Leaktightness of pipes
WARNING
Risk of burning from hot gas
Escaping gases are hot and will lead to serious burns in the event of contact.
u Check all pipes for leaks in accordance with the enginebuilder’s instruc-
tions.
Wear safety gloves to protect against thermal hazards.
Gas, air and oil pipes
u After starting the engine, check all gas, air and oil pipes for leaks.
4.2.4 Checks when starting up the engine
If present:
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 Eliminating malfunctions →82).
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. In
the event of a leak, contact a Turbo Systems service station.
