What to do if my MTU Engine turns but does not fire?
If your MTU Engine turns over but doesn't ignite, it could be due to poor rotation by the starter because of a low or defective battery; in this case, charge or replace the battery. Another reason for poor rotation could be low air pressure; check the compressed air system. It can also be a defective fuel system; in this case, vent the fuel system.
Why is the exhaust gas black from my MTU Engine?
If the exhaust gas from your MTU Engine is black, it could be due to a clogged air filter. Inspect the signal ring position of the service indicator. It could also be due to a defective injector, which would need replacement. Overloading the engine can also cause black exhaust gas, in this case you need to contact service.
What to do if MTU Engine turns but does not fire?
If the MTU Engine turns but does not fire, the battery may be low or defective, leading to poor rotation by the starter. You should charge or replace the battery. It can also happen because the fuel system is not vented, in this case vent the fuel system. For other Defective causes, contact service.
Why is the exhaust gas white from my MTU 20 V 4000 G63L?
If the exhaust gas from your MTU Engine is white, it may be because the engine has not reached its operating temperature; run the engine until it warms up. Another possible cause is water in the fuel; in this case, check the fuel system on the fuel prefilter and drain the fuel prefilter. Leaking can also be the cause, contact service.
What to do if MTU 20 V 4000 G63L Engine does not reach nominal speed?
If the MTU Engine does not reach nominal speed, it could be due to a clogged fuel prefilter or fuel filter, which should be replaced. A clogged air filter could also be the cause, so check the signal ring position of the service indicator. Additionally, a defective injector could be the problem, requiring replacement. Overloading the engine can also prevent it from reaching nominal speed, in this case, contact service.
Why is the exhaust gas blue from my MTU 20 V 4000 G63L?
If the exhaust gas from your MTU Engine is blue, it could be caused by too much oil in the engine. Drain the engine oil to resolve this. Another potential cause is a contaminated oil separator of the crankcase breather, which would need to be replaced. Defective parts can also be the cause, contact service.
What causes the MTU Engine speed to be unsteady?
Unsteady engine speed in your MTU Engine can be due to a defective injector, so replace it. It can also be caused by a fuel system that is not vented, so vent the fuel system.
Why MTU Engine does not reach nominal speed?
If your MTU Engine isn't reaching its nominal speed, the fuel prefilter or the easy-change fuel filter might be clogged, so replace them. Also, the air filter could be clogged; check the service indicator. A defective injector can also cause this issue.
Why is the exhaust gas black in my MTU 20 V 4000 G63L Engine?
Black exhaust gas from your MTU Engine can be caused by a clogged air filter. Another potential cause is a defective injector.
What causes charge air pressure to be too low in MTU 20 V 4000 G63L?
If the charge air pressure is too low in your MTU Engine, the air filter might be clogged. Check the signal ring position of the service indicator. Contamination or other defective parts can also cause this issue, requiring you to contact service.
