GEVO 16 in ES44AC
Posted by caldreamer on Friday, July 15, 2011 8:22 PM

I am wondering if the GEVO 16 cylinder engine will fit in the engine compartment of an ES44AC which has a GEVO 12 cylinder prime mover or would it be too long with the 4 extra cylinders (2 per side)..

No - the 16 cylinder engine is about one third higher horsepower and would require a larger {read longer} radiator as well as a larger air - to - air after cooler. This all requires a longer frame which is fortunate for adding a longer fuel tank. 

Revision 1: Adds this new piece Revision 2: Improves it Revision 3: Makes it just right Revision 4: Removes it.

Actually, you might get the 6000 HP 16 cylinder GEVO to work in in an ES44AC. The ES44AC is less than 3 feet shorter than the AC6000, so with some creative rebuilding, it just might fit. However,  why bother go through all the trouble? GE would be happy to build a new ES6000AC if anyone is interested. They got all the kinks worked out from the original model when they re-powered CSX's AC6000s with the new GEVO 16.

All the GEVO 16 engines so far are set up for water to air intercoolers. This includes the CSX and BHP Billiton rebuilds which have these because the previous HDLs had water intercoolers. However, the new design locomotives in China and the new Brazilian ES59aci units have water to air intercoolers. As far as I know GE have never built an air to air intercooled GEVO 16, which might be because it would be so big that the locomotive would need to be larger, or at least longer than an AC 6000. The ES59aci is very similar to an AC 6000 built to a reduced clearance outline. GE would be happy to build you on to normal clearances.

So, there are indeed CSX AC6000CWs in existence RIGHT NOW with GEVO-16 prime movers installed in their carbodies? I wasn't aware CSX had already begun this program.

 

Does anyone know of a place where I can find a list of repowered CW60ACs?

 

EDIT: Also, I do wonder what is happening to the 7HDL16s that are coming out.

All of CSXT's production-model AC6000CWs have been repowered with GEVO16s.  The first to be completed was unit 628 in September 2007; and the last to be completed was unit 610 in December 2008.  The three pre-production units (600-602) were also repowered; but they received 4400-hp 7FDL-16s because of cooling-system limitations.

Wait, you mean there aren't any 7HDL16's left?! I never got to hear one! D:

 

I've been told they had quite a growl to them.

I think that there are a handful of UP AC6000CWs left. Your best bet is to search YouTube.

While a little off topic, I found a thread that shows the air to water intercoolers on the GEVO-12 in the Kasakhstan class TE-33A....

http://englishrussia.com/2011/04/25/evolutional-production-of-locomotives/ 

There are photos of these in service at

http://www.railpictures.net/showphotos.php?railroad=Kazakhstan%20Railways

I had assumed that these units used FDL engines since there was no sign of of an air to air intercooler.

Similar intercoolers are fitted to all GEVO 16 engines in locomotives, so far.

The GEVO16 sounds the same as the 7HDL16. The GEVO prime mover is based on the HDL and incorporates design changes that correct the flaws in original HDL design.

The only 7HDL16 powered units left would possibly be a few UP AC6000CW's.

Any HDL prime movers removed from the AC6000CW's will go to scrap. The AC6000CW's were the only units to use this engine. GE nolonger supports the HDL prime mover, which was the ultimate reasoning for repowering of the AC6000CW's in the first place.

Good info, thanks! It is upsetting to hear that the engines will all be scrapped. I would hope that someone, somewhere would grab one and put it on display in a museum. Maybe the GE Transportation Museum will save one?

Given that an HDL-16 and a GEVO 16 look almost identical who is really going to pay to preserve the prime mover?

Not really a good reason. It may be similar, but not the same. Sounds different, I would imagine.

Good Day,

My imagination at work again.........presenting the GE ES55AC.  How about a GEVO 16 cylinder with 5500 hp?

Here's a link to a genuine ES58ACi!
