Locomotive engine

[EMDDIESEL]

I got a few E-mails asking for Locomotive Prime mover pics and Cab pictures, so here you go:#ad


The engine shown is the 710G3 and is one of the most common EMD engines and is used in the SD60M/I locomotives and others. It is a 16 cylinder, 2 cycle 3,800HP engine. Each cylinder is 710CID. The engine as shown weighs 39,600 pounds empty.

WoW

Awesome pictures!! It is just incrediable how large these engines can be, and with so much horsepower. Thanks for posting !!!

The quality is not great on this, but at least you have an idea of how 99% of EMD engines work. The exception being there new 16V265H 6,200hp twin turbo 4 cycle engine which i cant post pics of.

There 20 Cylinder engines are the same as the 16 cylinder versions, they just have 4 more cylinders.

I updated the picture, hope the clarity is better

EMD,



Does CSX have any SD-70MACs? Those have a 4000 hp 16V-710 engine I believe, don't they?

Looking at the diagram, it looks like each pistion has an oil line (for cooling) running up inside it from the bottom. It would seem like thoses hoses would fatigue awfully fast from all the flexing as the piston goes up and down. I wonder what the hoses are made of? I assume they're braided steel, but maybe they're some kind of high tech plastic? Interesting! Also, it's hard to tell by the diagram, are there four exhaust valves per cylinder, or two?

710 cubic inches per cylinder ! Wow!

Thanks for the posting.

We have alot of SD70MAC's now. Yes, they are 4,000HP and the engine is the 16-710G3C-ES. Unlike the SD60 the SD70MAC's have EFI which contributes to the increase in HP. They are one of my favorite engines to run, they can pull anything and never stall.

 

[EMDDIESEL]

That line you see under the piston is called a "Pee pipe" and is not a hose, but a hard line that does not move, it sprays oil under the piston to cool it. The diagram as mentioned is really bad, but the line you see is supposed to be the stream of oil. If you look close you will see where the line ends and the oil stream starts. And each cylinder has 4 exhaust valves.

EMD my Dad used to work for Conrail. Those suckers still leak like crazy? This was some years back, they might have changed.

UP ordered 1000 new SD-70s, I know we have gotten some of them but not all of them.

Wow

EMDDIESEL, was just wondering how many barrels of oil does the 710G3 hold? Thanks for the great pics.

 

[EMDDIESEL]

436 gallons of oil in the engine, thats about 1,334 quarts or about Eight 55 gallon drums. They dont do oil changes, just filter changes every 92 days (there are 10 disposable filters and two different strainers) and they top off the oil when needed unless oil sampling shows a problem. The difference between high and low on the dipstick is about 120 gallons. The locomotive the 710G3 is in holds 5,000 gallons of fuel and 276 gallons of water for cooling. And you thought your ISB was expensive to maintain



As to Patriots question regarding leaks, yes, they do have small leaks in some places, but generally they are in good shape since the FRA enforces enviormental laws on oil leaks. The crankcase breathers blow off alot and people think the engines themselves are leaking. The engines i always find leaks on are the older CP Rail units, they are horrible. The cleanest i have seen are UP and BNSF with CSX a close third in lack of oil leaks.

Okay, I see. Thanks. BTW, how much does a new SD-70 cost? Is the SD-70 the ultimate, top-of-the-line locomotive, or is there such thing as an SD-80 or 90?

EMDDiesel, is that an aluminum hulla-hoop in your hand or did you just remove the silencer ring ???

Very neat EMD. I would have thought they would hold more than 5000 gals of fuel though. I am an air show freak( Navy Blue Angels/Air Force Thunderbirds). At a Blue Angels show it was stated that one FA 18 Hornet used 8000# or 1300 gallons of JP-5 in one 35 minute show. Also stated one FA18 has more power than the entire starting grid at Indianapolis 500. Air Force Thunderbirds fly F-16 Vipors. More powerful yet.

The bigest EMD is the SD90MAC which is 6,000HP with a 4 Cycle 16 Cylinder engine. then there is an SD80MAC which is 5,000HP with a 20 cylinder engine 2 cycle engine.

The SD70MAC is the most popular now (like Kat Diesel said, UP Just ordered 1,000 of them). The cost varies on options and quantity but a fully decked out version is about 2. 1 million. UP's order right now are actually stripped down versions with older mechanical style brake controls to help keep the cost down of such a massive order. Our (CSX's) order which was for about 130 has digital electronic brakes and other bells and whistles (no pun intended) that increase cost.

The biggest fuel tank on any engine now is 5,800 gallons. The biggest ever, which by the way is (or was) considered the largest land based mobile fuel tank built was on UP's DDA40X Locomotives and that tank was 8,200 gallons. But those engines are not used anymore in regular service.

The DDA40X It still is considered the largest diesel ever built at 98-1/2" feet long and 6,600 HP but it had two 16 Cylinder engines in one body and it did not have as much pulling power as an SD90MAC which is only 89' long and 6,000HP and only has one engine. You can see how economics and technology prevailed. Here is a small photo of the DDA40X #ad

What dies it look like.

EMD, do you have a picture of the SD90MAC? I would like to see what it looks like, or does it look similiar to the rest ?

I'll see if I can find a picture.



UP 8500 - 8561 SD90AC 6000hp

UP has 62 of them I am sure I can find a picture somewhere.







Here is the "counterpart" made by GE, we got 54 of these.

UP 7500 - 7554 C60AC 6000hp

Here's a picture of the SD-90MAC from the EMD web site:

Looks more like a GE locomotive than a traditional EMD locomotive to me.

 

[wxman]

What do the SD-90MACs and the AC6000s sound like? Anything like the traditional "rap" of the older GE four cycle engines? I haven't had the opportunity to see either of these engines in action yet.



The AC6000 is based on a Deutz Series 632 marine engine, so it's a somewhat different design than the older GE "FDL" engines.
