Operating medium: Heavy fuel and distillate fuel
Inspection:
of fuel limiter every 3,750 h
Note:
This unit limits the fuel injection depending on the carge air pressure so as to avoid a
smoky exhaust. The exhaust can become black in the event of a rapid speeding up or a
brisk load increase. The fuel limiter is only installed on reversible engines and is operable
from a lubricating oil pressure of 0,8 bar. If the oil is contaminated, this may disturb
operation.
A defective fuel limiter can be cut out, during engine operation, by turning the set screw in
(item 11 on 05.04.02.nn).
Remove the lead seals only if a resetting is necessary.
Sequence of operations:
1. Check all bolts and screwed
connections for tightness.
Repair any leaks (05.04.02.nn).
2. Check adjusting screw (Fig. 1/1) whe-
ther it admits starting fuel so that star-
ting is positively possible.
3. Check the actuating speed when the
engine is warm.
3.1 Set the control handle rapidly on full
load at an engine speed of
0,3 to 0,5 max. speed.
