What causes too high lubricating oil temperature in WÄRTSILÄ Engine?
Excessively high lubricating oil temperature in a WÄRTSILÄ Engine can be attributed to a faulty thermometer, insufficient cooling water flow through the oil cooler (due to a faulty pump, air in the system, or a closed valve), a clogged oil cooler, or a faulty thermostat valve.
Why does my WÄRTSILÄ Engine produce dark exhaust gases?
Dark exhaust gases from the WÄRTSILÄ Engine can be caused by late injection due to a wrongly set camshaft drive, insufficient charge air pressure because of a clogged air intake, a dirty turbocharger compressor, a charge air cooler clogged on the air side, or a badly fouled turbocharger turbine.
Why is the exhaust gas temperature of all cylinders abnormally high in my WÄRTSILÄ Engine?
Abnormally high exhaust gas temperatures across all cylinders in a WÄRTSILÄ Engine can be due to the engine being badly overloaded, high charge air temperature (caused by a clogged or dirty charge air cooler, high water temperature to the air cooler, or abnormally high engine room temperature), excessive deposits in cylinder head ports, or high exhaust pipe pressure after the turbine.
What causes a WÄRTSILÄ Engine to fire irregularly with some cylinders not firing?
Irregular firing or misfires in some cylinders of a WÄRTSILÄ Engine may be due to issues related to fuel and air supply, injection pump control rack wrongly adjusted, injection pump control sleeve not meshing properly with rack, or a faulty injection pump (plunger or tappet sticking; delivery valve spring broken, delivery valve sticking, constant pressure relief valve leaking).
Why are there knocks or detonations in my WÄRTSILÄ Engine?
Knocks or detonations in a WÄRTSILÄ Engine can occur due to excessive big end bearing clearance (loose screws!), broken valve springs or injection pump tappet spring, inlet or exhaust valve jamming, too large valve clearances, overloaded cylinders, a loose injection pump or valve tappet guide block, initial piston seizure, insufficient preheating with low ignition quality fuel, or incorrect fuel injection timing.
What does it mean when a WÄRTSILÄ Engine has blue-whitish or gray-whitish exhaust gases?
Blue-whitish or gray-whitish exhaust gases from a WÄRTSILÄ Engine can indicate excessive lubricating oil consumption (due to gas blow-by, worn or broken oil scraper rings, worn cylinder liners, sticking compression rings, compression rings turned upside-down, or ring scuffing). Blue-whitish exhaust may also occur after idling for a long time or at low ambient temperatures, or shortly after starting. Gray-whitish exhaust can be due to water leakage from the exhaust boiler, turbocharger, or water in the fuel.
What to do if WÄRTSILÄ Engine does not stop?
If a WÄRTSILÄ Engine fails to stop even when the stop lever is engaged or a remote stop signal is sent, it could be due to a wrongly set injection pump control rack. In such cases, block the fuel supply as close to the engine as possible (e.g., using the fuel filter three-way cock). Before restarting, identify and correct the fault to prevent overspeeding. Alternatively, a faulty stop automation may be the cause; in this case, stop the engine using the stop lever.
Why does my WÄRTSILÄ Engine suddenly stop?
A WÄRTSILÄ Engine may stop due to a shortage of fuel, the automatic stop device tripping, a faulty governor or governor drive, or a faulty power supply to the automation system.
What causes abnormally high cooling water outlet temperature in WÄRTSILÄ Engine?
An abnormally high cooling water outlet temperature, coupled with a large temperature difference between the inlet and outlet in a WÄRTSILÄ Engine, can arise from a faulty temperature sensor, a clogged circulating water cooler, insufficient cooling water flow, or a malfunctioning thermostat valve.
Why is the exhaust gas temperature of one cylinder below normal in my WÄRTSILÄ Engine?
A lower than normal exhaust gas temperature in one cylinder of a WÄRTSILÄ Engine may be due to a faulty exhaust gas temperature sensor, leaky injection pipe or pipe fittings, or issues with fuel supply.
