b.) On the right side of LDU-Screen, turn the control key to the right to increase the SBM-
Offset-%.
2
Press the control key to acknowledge the selected value of the Exhaust-Valve-Operation-
Offset.
NOTE:
Adjusting the SBM-Offset advances the exhaust valve opening timing. This leads
to an increase of the exhaust gas temperatures of the cylinder. Depending on the
engine load, the exhaust gas waste gate will also be opening and closing for steam
boost production. This is a desired effect to further increase the exhaust gas
temperature before entering the economizer.
