Operation Manual / 4 Product description / A130-H.. - A140-H
5 Operation and service / 5.4 Stopping the engine
Influencing parameters
The specified values are guideline values and are not guaranteed. The actual values can devi-
ate considerably from the guideline values, for example, due to the following influences:
¡
Fuel quality and fuel treatment
¡
Load profile (thermal cycling, also number of starts/stops, emergency shutdowns, oper-
ating point)
¡
Gas inlet temperature
¡
Turbocharger specification.
¡
System-specific operating conditions (combustion quality, exhaust gas composition)
For bearing parts
¡
Lubricating oil quality (oil filtering, oil condition, oil monitoring)
¡ Load profile (speed, pressure conditions, temperature)
¡
Number of starts/stops
¡
Unbalance of the rotor (degree of contamination).
5.4

Stopping the engine

CAUTION
Residual heat in the turbocharger
If the residual heat in the turbocharger is not adequately dissipated, it may
damage the engine.
Adequate cooling of the turbocharger must be ensured after stopping
u
the engine.
Water-cooled turbocharger variant
Post-lubricate as long as the rotor is turning.
u
Observe the oil pressure while performing post-lubrication: 0.5 < p
u
Switch off post-lubrication as soon as the rotor is stationary or after no more than two
u
minutes.
Deviating procedures must be coordinated with ABB Turbo Systems.
