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 ex-
haust. The exhaust can become black in the event of a rapid speeding up or a brisk load increa-
se. 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) whether
it admits starting fuel so that starting is po-
sitively 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.
Position while speeding up
