Preventive measures, see chapter 03 and 04. Some possible
operating troubles require prompt action. Operators should ac-
quire knowledge of this chapter for immediate action when
needed.
Trouble
Possible reason
See chapter,
section
1.
Crankshaft does not rotate at starting attempt
a) V-engines: The turning device is connected.
In-line engines: The cover on flywheel protection is open.
NOTE!
Engine cannot be started when turning device is connected.
However, before starting, always check that turning device is removed.
11.1, 21.1
b) Starting air pressure too low, shut-off valve on starting air inlet pipe closed.
21.1, 21.5
c) Jamming of starting valve in cylinder head.
21.4
d) Jamming of starting air distributor piston.
21.3
e) Starting air solenoid valve faulty.
21.2
f) Inlet or exhaust valve jamming when open. "Negative" valve clearance
(strong blowing noise).
12
g) Starting automation outside engine faulty.
03.1.2, 23.
h) 4R22: Starting motor faulty.
21.6
2.
Crankshaft rotates but engine fails to fire
a) Too low speed (1b).
b) Automatic shut-down device is not in start position.
23.
c) Load limit of control shaft or of governor is set at too low a value.
22.
d) Overspeed trip device has tripped.
22.5, 22.6
e) Starting fuel limiter wrongly adjusted.
22.3.5, 22.7
f) Some part of fuel control mechanism jamming and prevents fuel admission.
22.
g) Fuel and injection system not vented, pipe connections between injection
pumps and valves not tightened .
17.3
h) Fuel filter clogged.
17.7, 17.1
i) Three-way cock of fuel filter wrongly set, valve in fuel inlet pipe closed, fuel day
tank empty, fuel feed pump not started or faulty.
17.7, 17.1
j) Very low air and engine temperatures (preheat circulating water!)in
connection with fuel of low ignition quality.
02.1
k) Fuel insufficiently preheated or precirculated.
02.1, 02 Fig 02-1
l) Too low compression pressure (1f).
m) Faulty governor.
3.
Engine fires irregularly, some cylinders do not fire at all
a) Jamming valves, inadequate fuel supply, too low temperatures.
1f, 2f,g,h,k,l, 4d
b) Injection pump control rack wrongly adjusted.
22.3
c) Injection pump control sleeve does not mesh properly with rack(may cause
overspeed if set in direction towards increased fuel quantity).
