Why MTU Engine does not turn when starter is actuated?
If the MTU Engine doesn't turn when starting, it might be due to a low or faulty battery, in which case you should charge or replace it. Another cause might be faulty cable connections; ensure they are securely seated. Other possible causes are related to the starter or engine wiring, and require contacting service.
What to do if MTU Engine fires unevenly?
If your MTU Engine fires unevenly, the possible cause is a defective injector, which needs to be checked and replaced if necessary. Other potential causes include faulty engine wiring or air in the fuel system, which may require venting the fuel system. A defective engine governor could also be the reason and requires contacting service.
Why MTU 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 needs to be replaced. Another cause is a clogged air filter, you should check the signal ring position of the service indicator. A defective injector could also be the reason, and it needs to be replaced. Other possible causes include faulty engine wiring or engine overload, and require contacting service.
What to do if MTU Engine turns on starting but does not fire?
If the MTU Engine turns on starting but does not fire, it could be due to poor rotation by the starter because of a low or faulty battery, which needs to be charged or replaced. If using an air starter, the pressure might be too low, so check the compressed air system. Other possible causes include faulty engine wiring or air in the fuel system, which may require venting the fuel system. A defective engine governor could also be the reason and requires contacting service.
How to fix black exhaust gas from MTU Engine?
If the MTU Engine emits black exhaust gas, it might be due to a clogged air filter; check the signal ring position of the service indicator. Another possible cause is a defective injector, which needs to be replaced. Engine overload could also be the reason, and requires contacting service.
Why MTU Engine speed is not steady?
If the MTU Engine speed is not steady, it could be due to a defective injector, which needs to be replaced. Other possible causes include a defective speed transmitter, air in the fuel system (requiring the fuel system to be vented), or a defective engine governor, and requires contacting service.
How to decrease charge-air temperature in MTU Engine?
If the charge-air temperature is too high in your MTU Engine, it might be due to incorrect engine coolant treatment, which needs to be checked. Another cause might be a dirty intercooler or high air-intake temperature in the engine room, so check the fans and intake/exhaust lines. Intercooler requires contacting service.
What causes blue exhaust gas in MTU Engine?
If the MTU Engine emits blue exhaust gas, it could be due to too much engine oil in the engine, so drain some engine oil. Another possible cause is a contaminated oil separator of the crankcase breather, which means you need to replace the filter. Other possible causes include defective exhaust turbocharger, cylinder head, piston rings, or cylinder liner, and requires contacting service.
How to troubleshoot low charge-air pressure in MTU Engine?
If the charge-air pressure is too low in your MTU Engine, it might be due to leaking air pipework, so check the air pipework for leakage. Another cause might be a clogged air filter, check the signal ring position of the service indicator. Other possible causes include a dirty intercooler or a defective exhaust turbocharger, and requires contacting service.
What causes white exhaust gas from MTU Engine?
If the MTU Engine emits white exhaust gas, it could be because the engine is not at operating temperature, so run the engine to reach operating temperature. Another cause might be water in the fuel, so check the fuel system on the fuel prefilter and drain water from the fuel prefilter. A leaky intercooler could also be the reason and requires contacting service.
