Union Pacific is testing an oxidation catalyst in one of their locomotives. The concept looks an awful lot like the trap ox in the 87 300D

Looks like they're installing it on an EMD SD60M for those who know their locomotives.

The turbos for these things can't be cheap...they're bigger than the engine in yer 300D

Spool up this baby on yer Honda!

For something as expensive as that you'd think they might crate it a tad better!

Guess that'll make the Fin's jealous......

Hey can I get two of those to go ? Yes , super size them please ..
I'd like to put one or two of those bad boys , on my Freightliner . Then we'll se what my speedo pics look like..lol.

:sperm:

I would definately get the girls with that .

I'll bet if I ripped out my engine and plopped that thing under the hood I'd get lots of Respek from the ricerocket cowd

It would make one heck of a jet.

Well if your car would be a jet , what would my tractor trailer be ?
A 747 maybe ? One thing is for certain , the loads would always be on time . How do you log that though ? I mean how do you explain to the D.O.T. officers how you went from Connecticut , to Los Angeles yesterday in 11 hours , got ten hours of sleep , and that now you're on your way back ???

take the back plate off and make it a shop fan ,nastalgia for those of you who want something unique ,made be GE even ,industrial strength.

Now that's an original idea... I like that, a shop fan .

I cant see those oxidizers lasting long. Those things burn oil when they idle, and they idle a lot. I'l try to get a picture of the smoke in the air from all the idling locomotives. On those particular locomotives EMD recomends only changing the engine oil once a year. The thought is that they burn enough oil that it's always being changed. it's not at all uncommon to ad 50 gallons of oil to the crankcase when they get fueled up.

Wow, if that's for a top off then how much oil do those things hold??

I'm pretty naive to locomotives, they use a diesel engine to power an electric motor right?

Idle nothing, hell, they burn oil when under load!!

Actually, this probably isn't oil. A railroading friend of mine claims this is pretty common on GEs in heavy wheelslip situations and that it's caused by the automatic anti-wheelslip system adjusting power settings too rapidly.

hmm, I don't know about that one. Dr. Porsche created one in the late 19th century. Depends on your definition of successful I suppose

Over 400 gallons, depending on the engine. The EMD 20-645E3 found in the V20 SD45 of the 60's and 70's holds 467 gallons of crankcase oil, 295 gallons of cooling water, and 4000 gallons of fuel. It puts out 3600HP at a maximum of 900 RPM. Idle is at 255 RPM.

Newer units have a "low idle" mode initiated by the computer that kicks in after a preset amount of time. Most modern locos also have an auto start feature, which shuts down the engine after a preset time period. If the air compressor needs to run, or if the engine is getting too cold, the computer will start it back up again. GE's new GEVO-12 (12 cyl) engine actually cuts the fuel to all but 5 cylinders when in low idle. They sound pretty funny when running on 5 cylinders, kinda like they're about to throw a rod

A lot of times those old GE's turn into flamethrowers because of a bad turbo. I don't think these things use an ALDA type device; the computer just figures that the turbo is there and knows how much boost it's making at a certain RPM, and adds fuel accordingly. And we all know what happens when we crank down on the ALDA too much, we get black smoke. The fire is the unburned fuel.
