Throwing off the metering. Its done it on my car, which is a diesel, so I can't imagine its that different on the locomotive.Explain how dirty fuel causes excessive fuel flow.It looks like, and sorta sounds like, a combination of excessive fuel flow and bad atomization, both of which are probably caused by dirty fuel.
Thanks!
Its not. Gas engines are externally carbureted, in that the fuel and air mix outside the combustion chamber. Diesels are internal. At the intake stage, air only is drawn into the cylinder. Fuel is injected at the end of the compression stage. The fuel, being injected at incredible pressure, meets the air which is also at incredible pressure and temperature, which causes ignition. No spark.i know that its fuel injected but if the fuel delivery system on these beasts works anything like a carb....
Complete combustion depends on clean injectors because of the need for atomization.
