My experience has been; because "smoke", and all the other "steam exiting features", are for play factor in the toy train world.
I was good with your answer Sir.
It applies to me and most of my guest operators.
Now watch the first minute and 1/4 of this video and tell me what color smoke I am seeing?
To me, it's closer to white than black. To others? I don't know.
How about from 21:50 to around 23 minutes? What color is that smoke? I feel it's like my video posted earlier of the MTH GP.
looks like we have been idling for a bit and the heavier parts of the fuel settled on the tops of the pistons anddidn't burn off till under a bit more throttle was applied.
More like the engine was cold, and not up to working temperature.
They sound like 4 cycle engines
No they don't, as EMD GP9 units are 2-stroke cycle engines without turbochargers, i.e. the have roots blowers mechanically driven off the rear camshaft gears.
and the turbo compressors wheels may have too much end play allowing a lot of low speed air slippage,
Nope.
also somebody up the supply line may be mixing in used motor drain oil
Now just where did you come up with THAT assumption?????
What it does sound like is, the lead unit is either "hunting" or experiencing wheel slip, thus unloading.
outside of Ca air board Cummins automotive operators have been re-cycling motor oil thru the fuel tanks for at least the last 50 years @3% or less Cummins actually made a oil change machine that did this
