c) Charge air temperature too high
- charge air cooler clogged on water side or dirty on air side
- water temperature to air cooler too high, water quantity insufficient
- engine room temperature abnormally high
Test Rec, 01.2
01.3
01.3
d) Excessive deposits in cylinder head inlet or exhaust ports
04.4, 04.5,
15.3
e) Exhaust pipe pressure after turbine high
9. Exhaust gas temperature of one cylinder above normal Test Records
a) Faulty exhaust gas temperature measurement 23., 03.4.1
b) Exhaust valve
- jamming when open
- “negative” valve clearance
- sealing surface blown by (burned)
c) Faulty injection valve
- opening pressure much too low
- sticking of nozzle needle when open
- broken spring
- nozzle cracked 06.1
16.4.4
d) Late injection 06.1, 16.2.3
e) Fuel supply insufficient (filter clogged) 17.
f) Injection pump faulty , fuel rack sticking in high 16.
g) Screw in injection pump lifter loose, check hight of screw 16.2
10. Exhaust gas temperature of one cylinder below normal
a) Faulty exhaust gas temperature sensor 23., 03.4.1
b) See points 2f, h, 3b, c, d, e
c) Leaky injection pipe or pipe fittings 16.3
d) When idling, see point 3g 03.4.1
11. Exhaust gas temperatures very unequal
a) See points 9a, c, e
b) Too low fuel feed pressure; too small flow through injection pumps
(see points 2h, i). May cause great load differences between cylinders although inje-
ction pump rack positions are the same.
Dangerous! Causes high thermal overload in individual cylinders.
01.2
c) See points 1f, 6b
d) When idling, see point 3g
e) Exhaust pipe or turbine nozzle ring partly clogged
f) Apply to 8- and 16-cylinder engines. The difference in exhaust gas temperatures
between two cylinders is normally higher.
12. Lubricating oil pressure lacking or too low
01.2
a) Faulty pressure sensor 23
b) Lubricating oil level in oil sump too low 01.1, 18.2
c) Lubricating oil pressure control valve out of adjustment or jamming 18.4
d) Leakage in lubricating oil suction pipe connections 18.1
e) Lubricating oil badly diluted with diesel oil, viscosity of oil too low 02.2.1, 02.2.3
f) Lubricating oil pipes inside engine loose or broken 18.
g) Lubricating oil filter clogged 18.
13. Too high lubricating oil pressure
a) See points 12a and c
14. Too high lubricating oil temperature
01.2
a) Faulty thermometer
