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.
3.2.4
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.
The measured values must be compared with the values of the acceptance protocol; differ-
ent operating conditions must be taken into account here.
Escape of oily fluids
Lubricants and pastes used for the assembly of the low-pressure and high-pressure stage
can liquefy or vaporise and escape as oily fluids during the initial hours of operation. Con-
tinual escape of an oily fluid indicates a possible oil leak.
If there is a leak, contact an ABB Turbocharging Service Station.
