- Starting, ramp up and full load of an EMD V20-710, 3.5MW generator. V-20 two-stroke diesel, 5000 HP.
Warm up / cool down @ 450 RPM
Rated speed @ 900 RPM.
Ramp up 0:25
Rated load 1:52
I worked on a 1,000 ton icebreaking supply-boat in Canada's arctic that had two 3,600, V-20 EMD's. Underway, they had this 'thrum' when they hit their sweet-spot. Very cool sound. Not intrusive at all. It was a lullaby for everyone on board.
The 645 v20? Since it was 3600hp?
Most likely those were derated 20-645's that the supply boats were using.I'm sure that they were actually reliable in other applications/apparatus.
The 20-645's with 4,000 HP were used in locomotives such as the SD45's & SD45-2's but weren't reliable.Due to extensive internal vibration combined with block weight,those units were notorious for causing severe damage to crankshafts or fracturing frames.Outside of the ones that were scrapped,later on they were rebuilt as SD45R's and then finally SD40M-2's.A certain amount of them are still around with leasing companies and a few railroads.Many of them that were rebuilt have the 16-645E3's being the same motors used in the SD40-2's with 3,000 HP.
The SD40M-2 designation was common for the SD45's owned by Southern Pacific,they were rebuilt by Morrison Knudsen in the 1990's during their final years.It was during the last phase when they were struggling with fiances on getting more locomotives for the roster.
i gotta be careful when i get my car's engine into stride. usually 3000rpm at around 70mph. that sound will put pretty much anyone to sleep with it's humming along the roadway
Definitely can't say that about the 16V-149's.
🚨
EMD- the one and only. A truly unique sound in a class of its own!
Yeah. They do sound nice. Haha. EMD. Converting diesel fueI into noise since 1938!
Unit comes up to speed (900 rpm) and stays as close to 60 hz, synchronizing relay will match the generator to be in phase with the utility power. When it's in "sync" the breaker closes and regulator starts to increase the current on the exciter, which causes the generator to output more current. There's a little more to it than that but that's the simple explanation.
Ha, bring back three lights and synchroscope!
@@KG84C It's got it for manual syncning.
if you ever go back here can you make a longer video for when it syncs and take the load?
@@RDC_Autosports It does a 5 minute warm up at 450RPM, then ramps to 900 RPM and normally takes less than a minute to sync and pretty sure it synced in this video. It doesn't block load and you can never tell when it syncs when you are next to it. Then it has a slow ramp to full load, but forget how long it it. This is a peaker and not for emergency, so it doesn't load quick at all. I won't be back there any time soon and they don't run this generator much at all anymore anyway, unfortunately.
@@inothome you mention they don't run the plant often any more. Are they getting phased out by the gas turbine plants? Or renewables /battery banks
Nothing in the wide wonderful world of pure power sounds like the simple to use, simple to run, simple to maintain EMD 2-stroke diesel. Keep the coolant and lube levels up, feed it clean fuel and she will purr like a kitten and pull with pure brute force 24/7… I do miss my days working for a bankrupted railroad… RIP MILW...
The 2 stroke has a faster torque rise than the 4 stroke and better low end.
There are four of these setting in the engine room of the stewart j cort 1000 foot great lakes ship
how would they do on castor 927 maxima, it burns much cleaner and it bean based, could pas the the crank and then burned of for total loss as this woulds elimnate waste oil energy, all sled, outboards, rotary and sachs diesel, field marshall 2 strokes use this principle and the field marscahll runs brass bushibgs total loss oil feed cranckcase pressurized!
EMD 2 stroke, instant power on command. 4 stroke GE, you better better widen throttle long before you need it, otherwise, you might get knocked in the floor.
EPA regulations and compliance is what truly killed EMD motors...At least many of them are still around and running as they still will for years to come.
As for locomotives,it's a good thing that CAT is EMD's parent company and bought PRLX,but once again...EPA is putting them in a standstill.
The EMD 2 stroke, in all forms close to the most reliable engines in the world!
I would put the mercedes OM617 used in cars in the 70s and 80s up there too.

@@bansibhai5734 if that generator became a motor would it be a powerful as the v20 2 stroke/ it seem electric motors are way more powerful for there size since a 3 phase motor fire 3 power strokes per rev out of one rotor chamber?
@@jlo13800 It depends. Most of the times generator is made to fit power output of the combustion engine. AC generatorc work at constant RPM, because you need proper frequency in electric line (50 or 60Hz in most power systems), so engine turns with the same speed at no load/minimum load and maximum load. The amount of power it outputs depends on load, that's the difference between generator engine and car engine. In car, you adjust fuel amount to get desired RPM, in generators there is sytem to adjust fuel constantly to stay at the same RPM (like a cruise control). If load increases, it adds fuel, but just enough to stay at that desired RPM.
Now, back to generators. It is posible, that generator could be able to output more power than engine, if it's designed "bigger", however you won't get more power than your engine is able to produce (substract loses), you would be able to top that generator with more powerful engine. However, if you overload generator, it will start to overheat. That's why a lot of motors (in locomotive for example) have constant and temporary power output. Electric motors and generators most of the times may be overloaded for short amounts of time, untill it will reach failrue temperature that causes windings isolation to melt and short circuit, that kills it. That's the biggest difference between electric motors vs combustion engine, which is not able to output more power than it's designed.
Most of the times you may use electric generator as motor and vice versa, but as far as I know it won't be as efficient as in desired function, because of some design differences. There are electric motor-generator sets, which are desired to work both ways, for example in pumped-storage power plants, where water from reservoir flows down to spin generators at high demand time, and when demand is low, they pump water back up. They use some more power to pump it up than they get from it flowing down, however, but thanks to changing electricy prices and other aspects it's very reasonable and profitable.
There's something absolutely right about an EMD going about its business. Beautiful sound and presentation👍
That "wine'' at startup is a awesome sound
Air start - nuclear safety related. The ones I worked on (construction phase) HAD to start in a few seconds and be generating full, regulated power in a couple more. Talk about redundancy, there are two of these per reactor. EACH generator had two, redundant air start systems fed by huge, dedicated air receiver tanks. These things are that critical.
@@Ricopolico I'm guessing they are to power all the systems of the nuclear plant in case the plant has an emergency and can't use the nuclear generated power anymore? So not at all to provide power to the grid but purely a backup for the plant itself. I'd imagine there are also battery backup systems with these generators for longer term power if nuclear power generation has to be stopped.
Great engines. We have a pair of 645s at the plant I work at as emergency generators. They are fantastic when maintained properly
Nuke plant? We have 2 of the V20-645's and 3 of the V20-710's.

I worked on a few tugs and supply boats with EMD eng from v-8 to v-20"s. Loved the way those engines sounded.
They would have had great response too!
Love the sounds of an EMD under load. That is some power.
Never forget watching an Ohio River tug w/2 barges coming around a wide sweeping bend and hearing that turbo-charged whine echoing in the early morning air! Nothing like that sound!!
This engine will last a lot longer than the ones in the locomotives... this is bolted to the floor, so there isn't any wip in the crank shaft, like when a locomotive hits rough track.
Great video!
Late reply...
But,the 20-710 G3B-EC's only being used in the SD80MAC's were actually very reliable and durable.They had no mechanical malfunctions at all,unlike the competing GE AC6000CW's with the 7HDL-16's which needed mandatory maintenance every three months due to seals giving out in the turbochargers or oil leaks and back pressure from the crankshafts.That's why Union Pacific extensively rebuilt them and they were turned into convertible C44ACM's while CSX derated them as CW44-6's before selling most to Progress Rail.
The attempted successor being the SD90MAC's H1's and SD90MAC-H2's from EMD were far worse.There was no troubleshooting or testing with harmonic balancing on the 265H's which costed them fractured frames,sheared mounts,and broken crankshafts to just list a few.Eventually they remained as convertible SD9043MAC's for Union Pacific and Canadian Pacific,they were built before the H motors were even finished to begin with.
@@Slim_Slid Yep, they were tough as nails machines. Too bad a three letter agency with zero public accountability killed an entire industry for a hoax.
@@Slim_Slid
UP didn’t rebuild them into convertibles, they were bought as convertibles with the lower horsepower engines so they could be used as C-44’s until such time as the bugs got worked out of the new engines, then they were to be converted into the higher horsepower units. That never happened in either case and the high horsepower units were re-powered with the old reliable 7FDL engines.
Edit: The C-44 ACM’s aren’t convertibles either, they are updated C-44’s that are going through a remanufacturing program at GE and are getting new cabs, some get carbody updates, all get updated computers with C-45 like software, and the latest ones have been getting the common rail 7FDL engines.
@@ralfie8801
You're literally explaining the situation that occured with the SD9043MAC's...Not the AC6000CW's.
The AC6000CW's were literally built with the 6,000 HP motors from the very start,until rebuilding occured later on.
The SD9043MAC's came out first before EMD even finished the 265H's.Even though having 710-G3B's which wasn't suppose to be permanent,they still had motor mounts for the 6,000 HP motors.
All of Union Pacific's AC6000CW's were rebuilt into C44ACM's and they still retain the 4,400 HP motors as they still did before that rebuild program happened,for EPA compliance and better electronics from Wabtec/GE.
They are still convertibles and have been just like the SD9043MAC's were.
Most of what is mentioned isn't news to me,please...Try again.
@@Slim_Slid
Nope, I’ve been working on the convertibles since they were purchased. The AC 6000 hit the rails first, then the problems started. UP needed locomotives, so they stopped acquiring the 6000 HP units and changed the remainder of the order to 4400 HP convertibles with the intention of upgrading them to 6000 HP units once the bugs got worked out with the new engines. It never happened. We never called the as built AC 6000’s convertibles, only the 4400 HP ones because they were the ones intended to be converted
UP never rebuilt their big 6000 HP EMD units, they were so bad they went back to EMD and were sold off to somebody else. The SD-90 43 units weren’t much better, they finally went away once a majority of them developed cracks in their frame rails. They were still problem children even with their 710 engines.
Now the problem children are the SD-70 AH models. They are literally the worst locomotives on rails at this time.
beautiful sound, love the crank up and idle up sounds
If that generator became a motorway it will be much more powerful for its size
Electric motors are magnetic rotary 2 stroke cycles!
Absolutely love the sound of the big EMD's!
As a Marine Engineer I first came across an EMD in 1979 on an anchor handling tug in the North Sea,then again on a drilling rig a couple of years later.It was mainly the 16 645 E9,s, which I thought were brilliant engines to run,and to work on and service.However in later years 2014 I came across the EMD,s again,but the 20 cylinder models this time and truth be told,they were a hell of a lot more problems,and serious ones at that.I dont know if EMD outsourced some of their manufacturing but the quality of the build was easy to see.Apart from the 4 extra cylinders putting extra stress on the crankshafts on the 20,s,these newer engines were without doubt not the same quality as the older ones.I have to say that in 45 years offshore on ships or rigs the EMD was my preferred engine,not everybodys,and they did drink oil,if the company did not budget for oil consumption they were in for a shock.My last job was a drill rig that had 10 20 cylinder jobs,and our oil consumption was rather large,the managers did not approve and would not allow scheduled oil changes as recommended by EMD,but would go on Scheduled oil samples,which we were getting done where we were operating,Brasil,so one may think,WERE they getting done,always the result came back oil good for further use,even though some of us engineers knew it was not, the TBN,s were always so low,mind you I dont think the quality of the NEW oil was up to much.Anyway,sorry for going on,wonderful engines
I think that is a good example of how just about everything has suffered or gone down in quality over the years.
The 710 V20's were made by EMD at the time because they were trying to see what was the maximum rating they could put on a engine.For locomotives,the 645 V20's were used in the SD45's & SD45-2's with 4,000 HP and then the SD80MAC's had 710 V20's at 6,000 HP (710 cubic inches per cylinder versus 645 cubic inches per cylinder).The 645 V20's didn't have great longevity or durability because of broken crankshafts and bending piston rods.Many of the SD45's back then were rebuilt as SD45R's with the same 645E V16's used in the SD40-2's to solve the problems.Nowadays they are designated as SD40M-2's for any that are still in service.The one mistake EMD made which caused the 710 series to exist was their debut of the 645F V16's in the GP50's & SD50's which were horrible.They broke the limit using 3,600 HP now figuring out they needed more displacement in order for increased horsepower.2 stroke diesel continously runs at higher RPM,therefore the higher it goes depending on the horsepower,the more displacement is required,meaning that if you don't have enough cubic inches/liters...Something will eventually break.
The last big mistake EMD created was jumping the 265H without testing harmonic balancing on the SD90MAC's and SD90MACH's.It was their very first 4 stroke prime mover while trying to use the same block as a 710 but with everything changed.There's a reason why they were manufactured later with the 710's as SD9043MAC's.Nowadays they're rebuilt as SD70ACU's.
The Caterpillar 1010J's in the Tier Fours is the successor to what the 265H's failed to be in the mighty macs.
The 20-645E fell from favor for railroad use the US in the early 70s due to fuel consumption and crankshaft issues. Some railroads de-rated their V20s to save fuel. These issues would send the V20 powered locomotives into early retirement, most were out of service by the late 80s. Their V16 powered contemporaries are still commonplace, but age is thinning their ranks. The last V20 powered units in the US were sold in 1975. None were bought by Canadian or Mexican railroads. The V20 would remain popular for marine and stationary use. EMD would not sell another V20 locomotive in the US until 1995 when the SD80MAC was introduced. Only 30 would be sold.
@@u686st7 There was much more than "30" SD80MAC's sold...Conrail owned all of them and then Norfolk Southern after the merge...CSX bought a dozen but then gave them to Norfolk Southern for a dozen SD40-2's in return as a trade deal...
I don't know where you got "30" from...
EMD is owned by Caterpillar now, so now they make junk.

@@AnontheGOAT Incorrect. When built, the SD90MAC was powered by the (then-new) four-stroke 16V265H engine EMD had designed for it. Later, most of them were re-engined with 16-cylinder 710G3 prime movers. No SD90 variant ever contained a 20-cylinder engine.
@@SpeakerPolice I wasn’t being specific to just the 20 cylinder but the 710 in general which the 43 had.
@@SpeakerPolice
Actually,most of the SD90MAC's being SD9043MAC's already retained their as delivered 16V-710 G3B's as convertibles all the way until Union Pacific and Canadian Pacific finally retired them.
The SD9043MAC's were already out and about while EMD was still trying to finish the problematic 265H.This is why those units also had extra motor mounts in place when originally the plan was to convert them all if the motors were actually reliable.Only a handful of SD9043MAC's were actually converted to the 265H's but all of them were scrapped soon after.None of them were re-engined because those units shook motor mounts apart and fractured frames on top of that.
The only units that actually came with the 265H's onboard from EMD were the small amount of SD90MAC H2's,which again nearly all of them were scrapped later on.The only other addition was the prototype SD89MX which never got any interest but is still owned by PRLX as some kind of testbed unit.
@@AnontheGOAT Yeah, the 9043s had 16-710s in them, but the 20-cylinder engines have a bit of a different sound to them (same as the 16-645 vs. the 20-645)

Unfortunately they are owned by Caterpillar now, so you can throw out everything you said. EMDs sales of new products nearly non existent.
Hard to believe GM had their hands in soooo many things. Back then it was just insane all the products traced back to GM.

Nothing like an EMD, Love these engines and their sound!
EMD 710 V - 20, Starting, paralIeling and loading. You can hear the turbo wind up as she picks up load about 0:44 or so. Love that sound. Unfortunately pretty expensive power that way. The older EMD's are lucky to hit 43 - 44% LHV thermal efficiency. While the newest combined cycle units wiIl do 63 1/2 % LHV now. Thus smalI gensets like this are good only for peak shaving, emergency use etc. In addition the EMD's etc. are relatively smalI medium speed engines. Won't burn black oil (hi viscosity residual fuel). Only distilIate (# 2 diesel etc.). Much more expensive.
Loox like the crew's checking terminal nut/bolt tork's with an IR temp. gun. Good M & R crew.
This so happens to be the same engine used in the SD80MAC.
Thge generator is small compared to the size ov the v20 2 stroke. If it became a motor it would be just as much power as the big 2 stroke, electric motors/generators seem to to have tremendous power for there size at low rpm hence the huge torque of an electric motor for its size.

@NYCTAFreak500 According to what I read the SDP40F's had EMD 645's. This engine here is a 710.
I remember back in I think it was 1968 a small town on the Santa Fe main line LA to Chicago I believe it was in either New Mexico or Arizona, the town relied on one high voltage line and a wind storm took out over 165 miles of the high voltage line. Few people had emergency generators but a lot of machinists lived there and worked for Santa Fe and when the town was informed it would take near a year to restore power the Santa Fe stepped up, the main line added a switch and parked a near new SD-45 on it right next to the substation for the town. Just over three hours after the engineer set the brakes and it was chocked using steel chocks welded to the rail they fired it up and it provided power to the entire town but couldn't run all the industry at the same time so local industry agreed to run at different times of the day so as to not to overload the generator. The one local business that was overjoyed to see it was the only fuel distributor in town. He got the contract to supply it with fuel. An SD-45 at 9 mph in the 8th notch of power which is full power will burn an average of 285 gallons of number 2 fuel oil per hour. The few that complained of the noise were told to shut up or get out of town. Just over 13 months later they shut her down and turned the grid power back on.
Just goes to show what can happen when stuff goes wrong there is always a way to come up with a fix.
The only time they shut her down was for regular maintenance.
EMD 710 V-20. STARTING, LOADING. Maintain 20 psi or so of lube oil pressure and lube oil and jacket water temp up to spec's and she'lI crank over and accept full Ioad immediately.
Bears repeating. This is the sound of an electric vehicle charging. 20 pistons each displacing more cubes than a 1975 Cadillac.
EMD the best
There ARE compression releases. They just don't have handles. They are located above the "Airbox" doors. Most Railroads WELD handles on them to make it easier to turn on older engines. On the railroad "blowing down"was known as "Barring the engine over"or "Bumping the engine" . This was done to eliminate ANY water that might be in the engine.

Its a backup genset for a hospital, 3MW output on the alternator
These engine installations often have an external heating system that keeps the engine at or near operating temperature. Some of these installations have an external oil pump system that is timed to circulate the oil, periodically. This keeps the oil at the engine temperature and the engine totally lubricated.
Nice vid! I have never seen an EMD so clean. It must be brand new? I had two 16-645's in a tug I ran. I don't understand why they continue to put the injectors and jumper tubes under the valve covers. We had continuing fuel leak problems dilluting the crank oil. But they did run hard. Screamin' Jimmies...
This genset is from 1999! It's well taken care of. As far as the injectors under the valve covers, where else could they put the injector and have it in the center of the head?
inothome I meant EMD could update their design to be like most other engines where individual cylinder heads are exposed and if any fuel leaks it runs down the outside of the block (CAT, Wartsila, Alco, Fairbanks, etc) rather than directly into the crankcase.
TheBigWWI I was an engineer on a dredge booster unit. Had a 20-645 driving an 80 inch impeller. That thing would sling some mud.
TheBigWWI The EMD design has been successful since 1938 ... no need to change it now.
Note than on the EFI-equipped engines, the two fuel lines to the unit injectors are metal reinforced neoprene, or something like that.
+PingasTheFourth Are they 4 stroke in Locos too? I think I heard something about Cat doing that.

very good engine in sd80 locomotives good job emd company.
Today they achieve almost 5000 hp with just 12 cylinders.Much less fuel used.
But more cylinders generally equals more torque. A 12 cylinder engine produces 4400hp, but a 20 cylinder one will always have substantially more torque than a 12 cylinder engine.

***** True, more valves and other parts to keep maintained as well in engine with more cylinders. But who doesn't love a V20 diesel!
*****
Nobody.
Except the guys maintaining tthem.
:D
***** Torque is meaningless when it comes to power generation. The generators are RPM sized for the frequency and speed. Lower speed gens take more torque than high speed gens. So whether it be a gas turbine or diesel, both can produce the same power output for a gen and both can be stalled easily by dead short circuit if no overload protection is used.
The SD80MAC Giant's heart is clearly seen!!
Future reference... the little plaques on the side of the engine and generator make good gearhead porn. Just sayin'...
scowell titis
I love that sound, back up generater.
20 plus years worth it sing me to sleep
.
Me too. And got me out of bed when they broke... :-)
BilgeDweller luckily that didn't happen much, cause its an EMD.
Yes, they will sing you to sleep, but if they shut down early, you are wide awake!
ESSE É UM DOS MOTORES DE COMBUSTÃO INTERNA MAIS PERFEITOS QUE CONHEÇO...
locomotive engine?
The 710-20 was the motor in the EMD SD80-MAC.
I think it is Generator
So yes.
Takes me back to the days of being a railroad machinist.
"this equipment can start at any time without noctice".
thanks, I failed to noctice...
I remember my days working on the CAT 3500's. I installed all of the air starters, Compressor, Air storage tanks, Piping. They ran awesome. This post is very cool. Nice smooth stuff there.
this is a three phase 4160 V generator, not a three phase 480 V generator.
This unit has a coolant heater that heats the coolant going to the oil cooler. The pre-lube / soak back pump pumps oil through the oil cooler, which actually heats the oil when the engine is not running. The soak back pump runs all the time to keep the heated oil circulating and the engine closer to operating temps. We have six EMD's of various sizes and all of them have the same configuration to keep the engine warm.
gallons per hour?
I forget offhand.
about 250
some of the best gens to work on right there... making me all nostalgic...
Put a V20 like this in a F1 car ;D :D :D
+indefinableme Too heavy. It would destroy the aerodynamics to the rear wing. The fuel stop would be 20 minutes.
But you can race with that engine for a century
And pulling 20+ boxcars
air start idle, then full power, then full load. Amazing power.
These were based off the Winton diesel engine design. Some of the most amazing sounding engines on the planet, ever.
oh that axel turbocharger scream when them gears are engaged ♥️😎
a power house. and very reliable. air starters. souands like yesterday.
I have seen this in other countries. This is power, EMD.
Bore and stroke 8.5 by 10 inches, and it's a 900RPM engine at 60 Hz. Drives an 8-pole AC generator.
lots of power at low RPM lie any big 2 stroke
I have seen detroits, cat, cummins...IH 345 nat gas, 225 slant six and 318/360 nat gas.
Never seen an emd!. That thing awesome.
150 - 180 gallons per hour? Thats pretty good! Makes our "little" Paxman sound like it has a hearty appatite at 2 litres of diesel per minute.
if it was going to blow? i wanted to be right there beside it. these engines are king. if you need emergency power 3 phase 4160V, this is it. to all nuclear power plants in the world, this is it.
We don't run the EMD's on waste oil but the Worthingtons used to.
Absolutely love the way this engine sounds!!
@jk037 EMD's like this one sound pretty much the same in locomotives to, ie - nice and smooth and just dam right awesome.
The daddy of all 2 stroke diesels, what a fantastic noise!
Yep. The turbo's add a lovely sound to an already amazing sound.
There is a coolant heater that heats the coolant going to the oil cooler. When the engine is off the oil cooler actually heats the oil and the soak back pump circulates the heated oil, 24/7. Of course when it's running the oil cooler functions as an oil cooler. Yes, locomotives do have a pre-lube pump you run before you start it.
Yes, people don't realize there is more to generation that just starting up and closing switches in the yard, it has to be synced to the same frequency as the grid!
Love the sound of EMD engines!!!
we have to have been the test bed for these babies back in the late 80's. crank in up. come in on a cold morning (29degereas) start it up, straight to full power and then load. the ait intake noise will blow your ears.
Power is Power EMD 710 is Power ! Bar None !!
Terrific engine all of the EMDs
These motors are my faves. Nice demo!
I am amazed at how quiet these monsters run for what they do, few can even realize what that 3.5 MW can do, trains would never stop on air brakes. I have seen many CAT V16 installs over the years and those babies are obviously a industrial / municipal supply. EDM is also a big submarine and tugboat pod propulsion contractor, they don't do small lol :)
Creep crank is fitted to new EMDs as Tylhunt mentioned. It it encounters hydraulic lock, it will blow the starter fuse before doing damage to the engine block. Well, thats what I was taught anyway.
