EMD 2 stroke locomotive diesel engine

[ollenhauer1]

uboot diesel,johann und diesel,das boot

[NamelessNLS]

10H version please!

[ArieskidChristian]

was it loud

[AlDF86]

This sound likes sound of 10D100 diesel)

[Bergsmyntan]

Isn't that a four-stroke engine? There are valves there.

[grayswandir47]

@Bergsmyntan - Two stroke diesels have exhaust valves at the top and intake ports at the bottom of the cylinder. The piston uncovers intake ports at the bottom of the stroke. The air supply is pressurized by the super or turbo chargers and flows into the cylinder displacing the combustion gasses out through the top of the cylinder. The exhaust valves close, the piston travels upwards with compression igniting the fuel and starting the cycle over.

[EWS60008]

I wonder if this power unit would fit into a Class 60 locomotive?

[danwat1234]

Why isn't oil spraying everywhere? How is the top being lubricated with no oil spray?

[dst28ims]

@danwat1234 theres no oil spray because emd runs a high flow low pressure system so at idle it has very low pressure like 5psi, on the 710 emd engines i'm told by emd any pressure at idle is good

[VitaminC440]

@danwat1234 This engine works on high volume low pressure.2 strokes all work this way. At idle they are at 10-15 psi.

[jerry91a]

thanks for pointing that out i was thinking of another ddec series

[master7chief]

How much boost do the engines run at idle and full load? Also whats their minimum and maximum RPM?

Thanks

[dst28ims]

@master7chief

not sure on boost but around 330 low idle and 1020 to 1040 high idle and around 3400hp + or - depends on if its blower or turbo and injectors and is its a 645 or a 710

[theicediamond7]

lot of power dont last like 4 strock

[jgmagoo1]

@jerry91a Series 60 Detroits definitely have both intake and exhaust valves. They are a common 4-stroke engine. Earlier Detroit and GMC diesels were 2-stroke and had no intake valves. Intake was through piston ports on the sides of the cylinders.

[K1ll3rM4st3r]

put your hand in there. i DARE ya! :)

[MrLocomechanic]

all too familiar to me!

[dj1111s]

How come train engines always sound like... train engines?

[Nagaroth2]

Chodzi jak tokarka.

[WARD5KUSTOMZ]

lets hear it without the muffler

[justforever96]

How do the lifters and valves get lubrication? Do you just put the grease gun to them every once in a while, or what?

[chargerfish1]

these use superchargers don't they?

[58Vulcan]

Bit ticky have you set all the hydraulic lifters?, EMD 645 ? blowers or turbo? looks nice ,has it had a rebuild the oil looks clean

[madboymax]

@58Vulcan EMD 645 roots blowers, first start after rebuilding the engine still needs tune up

[dodgeramb59]

@58Vulcan No setting of bridges (lifters) required on these. They are either working or not (collapsed bridges). OP says it was initial start after a rebuild, so Im guessing all the bridges are new and the oil just hasn't gotten up to pressure on them yet. If the bridges are not all new, then there is a possibility some are bad, I can hear them too. Checking is easy, stick your fingers in there when running.... slight nip/bite? its bad, no nip.... its good to go.

[drkmanracer302]

@58Vulcan thought that sound was the pressure from the fuel being injected

[PlatniumProductions]

how many cylinders is that? 8?

[madboymax]

@PlatniumProductions V16



[supsup85]

that is a lot of activity

[josippetrlic]

[josippetrlic]

@madboymax vidio po boji sa strane, inače bi se teško skužilo, svaki 16-645E skoro radi isto :)

[BikerRussell]

Interesting. Is that 6 intake valves? 3 on each side of the cylinder? And an exhaust in the middle?

[rickbell7]

@BikerRussell

Four exhaust valves per cylinder. The arm in the center is for the mechanical fuel injector.

The air intake is through ports near the bottom of the cylinders.

[BikerRussell]

@rickbell7 Fascinating. Thanks!

[EATSLEEPDRIVE2002]

one of the worlds most beautiful sights...the exposed operating valvetrain of an EMD motor like this one.

[formidable38]

Probably the finest and most reliable locomotive engine ever built!

[ZEG8704]

These beautiful engines in the old glorious T44 locomotives remembered everything. :-)

[123exmarkboy]

Oh my bad I see it is a two stroke engine I did some research and I see how they work,sorry about that I'm used to weed eater two stroke engines .

[pdlip1]

@123exmarkboy

All EMD engines except for the H power SD90MAC are 2 stoke where as the GE power engines are 4 stoke. They have a very different sound to them.

[123exmarkboy]

Or 7 valves per cylinder it's hard to tell

[123exmarkboy]

How is it a two stroke engine. Two stroke engines don't have valves and there is clearly valves,9 per cylinder, but other that that cool vid .

[silicon212]

@123exmarkboy It's not 9 valves per cylinder. There are 4 exhaust valves -- two valves are operated by a 'bridge' which itself is operated by the camshaft follower. The middle spring under the bridge is for the bridge itself - there is no valve at that location. In the center of the cylinder is a unit fuel injector, which is operated by the center cam follower.

[madjimms]

Holy crap, how many valves per cylinder? It (looks) like its got like 6 or 9 per cylinder! But I could easily be wrong.

[generator5500w]

right this is V16?

[jjdrummerboy1987]

for the past few weeks, i helped do an overhaul on two of the v12-645's i think thats the number. for the galveston ferry and despite being filthy f****ng dirty, reaching in the oil pans and handling the heavy ass pile packs, i freakin had a lot of fun and learned alot. im no mechanic, but now want to get my hands dirty.

E - M - D = EVERY MOTHERFU***** DAY!

[mjndblain]

i want to put this in a car.,...

[13Anko]

Simple. small 2 stroke diesels arent good performers in the High rpm range and than they become very inefficient. They're ment for low rpm and lots of torque.

Also, a 2 stroke diesel will vibrate alot more than a (pre-chamber) 4 stroke one does. its why diesels make the classic thump thump thump sound.

Most 2 strokes also typically dont run more than around 1000rpm(at max), simple because they cant run any harder...

Look up at some dodge owners, some modify their trucks with cummins

[13Anko]

@13Anko

Engines to gain more power.. Most of them are equipped with a turbo to gain more rpm/high end power into the engine.

But, there might be some other reasons i am not aware of.. not sure.

The whole thing about diesel is that the combustion speed isnt big enough for high rpm engines(wich we need in cars)

[arriviste2020]

@arriviste2020

Ran out of time, sorry.I think you will find that the lowest rated RPM for a D.D. series is 1900 RPm and max 2800 RPM. Might be a little 'off' by a few RPM.

[Mutleytech]

Easy valve adjustment. Ha,ha.

[speedy02]

A 6.0 Powerstroke will make more power and pull better any day!

[silicon212]

@speedy02 Your Powerchoke stands no chance against one cylinder of this engine. 6.0 = ~365 cubic inches, this engine is 645 cubes on ONE CYLINDER.

[GGGRRiny]

back when emissions where bullshit!

[barjan82]

what a beautiful sound! :)

[boysclubformen]

How did I get here from base jumping videos...

[maz323se]

Most EMDs, atleast about all in the locomotive world are 2 Stroke. the biggest way of telling is their smooth rumble. GE on the other hand is a 4 Cycle and sounds like a bunch of bolts turning in a slight oil bath in your mothers dryer. It sounds unorginized, but 4 Cycle diesels do at 400 rpms.

[gonetoworkbbackin5mi]

Oil should be flying everywhere

[robby844]

@arriviste2020 the top end doesnt need as much oil as you think. if you take the time to actually look you can see oil running down in the valve pan

[robby844]

@arriviste2020 ill take my opinion and just walk away. have a nice day

[robby844]

@arriviste2020 youre wrong. simple as that. ive worked on plenty of these when i worked for CAT (yes we work on anything that has pistons) and this is all the oil that was ever produced in the valve gallery

[arriviste2020]

@robby844

Well, I'm not going to argue with you, To simplify it further, check out the video showing the tugboat engine room and the EMD running, lots of oil being supplied to the valve and rocker gear, it's even traveling along the camshafts. In fact, a pre-lube pump would push out more oil than the EMD in the video to which you allude. The floor is yours.

[robby844]

@arriviste2020 watch?v=A4TsgAQOSNY&feature=re­lated

[robby844]

@arriviste2020 so post the link. there are over 30 vids of EMD's in tugs that prove youre full of shit.

[robby844]

@arriviste2020 and yet you still havent posted any links to prove me wrong... but yet you are certed for the same exact companies i am. i was a TECH for CAT for 3 years. then they didnt want to pay us for mileage so i quit. went to work at a shop that specialized in cummins and quit when i found out just how shitty their engines really are. now until you post SEVERAL video links proving me wrong you are still full of shit. even wabash said you cant make a justification... so.... yeah....

[robby844]

@arriviste2020 uhm ok then... i never said you didnt know how to put out the airbox fire. i have never experienced it

[robby844]

@arriviste2020 wow really? i have never worked on a locomotive a day in my life. why are you telling me i have? i worked on EMD as gensets in hospitals, schools and airports. please keep going. this game is fun. like i said post the link you raved about or you are full of shit. its so simple but yet you still will not do it... which only points to one thing... YOU ARE LYING

[robby844]

@arriviste2020 so all the proof i have just showed that you are lying is irrelevant? shows how much you know about an EMD. and yes you did state that i have worked on locos. this conversation is over because you cant even admit what a lying sack of shit you are and i proved it with three links!!!

[arriviste2020]

robby844 Your going from silly to stupid, there are no postings in which I stated that you worked on loco's. personally I care little. If, by any chance you are equating the reference to traction motor's intimating that you worked on loco's,you really are ignorant. Drilling rigs, and dump trucks also use traction motors Your ignorance certainly isn't going to affect the world of prime movers to any great degree. Hopefully your future efforts will meet with greater success.

[robby844]

@arriviste2020 and yet you are still on the fact about me working on loco's... so you admit you lied about the oil?

[arriviste2020]

@robby844

If you really do think that the main oil pump in the EMD engine in that vid, is putting out factory spec GPM at idle, then there isn't a lot of hope for you. I would go as far as to say, that not only do you not know,the GPM of the pumps in the lube system. You have never actually tested them in any unit which you allegedly have re-built. Hence the absence of your knowledge. I think your a parts changer, not a mechanic or technician. Nothing wrong with that,Lack knowledge is all.

[robby844]

@arriviste2020 you just fucking said that the tug boat video (in the link i posted) had adequate oil flow and now you are claiming it doesnt? the other two links are freshly rebuilt engines with the same exact flow that this video has and now you are an expert? you know nothing about what you think you know. your best bet is to shut up before you dig your grave any deeper. thats the reason why you didnt post the link. it proved you were lying

[arriviste2020]

@robby844

Contraire. I stated that the vid on this page, showing the engineer on the Tug starting the eng demonstrates how oily an EMD gets in the rocker boxes. No link required or stated.Expert moi? No, but I know how much oil an EMD lube, scavenge, and piston cooling pumps put out at idle and top speed. I also know what the min oil pressures are supposed to be and the max oil pressure. That doesn't make an 'expert', it merely indicates that some people know their core subject.Unlike you.

[robby844]

@arriviste2020 you claim you know everything about the EMD series but yet you used GPM... you dont need GPM to put oil in the valve galley. you need pressure you ignorant dipshit. and yes you did say that oil was ''flowing abundantly'' in the tug video. now you are trying to cover your ass because you got proved that you were lying. of course it gets oily in there its a detroit for god sake. any simple minded moron knows that! wait... you didnt so i guess not. and yes i have >

[robby844]

@arriviste2020 now you are just severely pissing me off trying to talk like you know and you dont even know. now post a link or make a damn video proving me wrong or else you are a lying sack of shit. thats 5 links (including the one you said had tons of oil flow) that proved you wrong. next youre gonna be like hunterco1 and tell me CAT doesnt have service trucks with booms

[arriviste2020]

@robby844

Do I care that your getting pissed off? Not at all, You have never flow-tested an oil pump on an EMD, and I very much doubt if you have ever checked the output pressire at source.If you had, you would have immediately stated that the main oil pump was within specs,End of story. You did not make the video, therefore you did not check the lube system. I'd bet, that on all the EMD engines which you claim to have worked on, you never checked the oil pumps for performance specs.

[robby844]

@arriviste2020 checked the flow of an EMD oil pump. output is usually 10-12 GPM at 80-90 PSI. so please tell me i dont know something again. now please tell me im lying again and ill go get my EMD manuals out of my work truck

[arriviste2020]

@robby844

Try 154 gpm @ high idle. for 16 cyl 185 gpm @ 900 rpm. Main oil Lube pump. You might be surprised, they only worry about MIN oil press. Max oil press can't exceed 125psi, No one has stated that your lying, just that your incorrect. And as your on a learning curve...8cyl, 12 cyl, 16 cyl and 20 cyl, all have different main lube gpm., as do the other two pumps in the lube system. Not including pre-lube, or soak-back pumps.

[robby844]

@arriviste2020 sorry i meant 110-120 GPM. my mistake. ill admit that. but yeah the video of the tug would be that oily because its a 2 cycle diesel and the oil gets sooty black 15 minutes after an oil change. i have videos on my facebook profile of and EMD in a museum that had 250 hours on the rebuild. you cant even see the paint color under the valve cover lids

[robby844]

@arriviste2020 watch?v=A4TsgAQOSNY&feature=re­lated

funny heres one wide open....

watch?v=4O-BaeXiri4&feature=re­lated

oh i see the one you were talking about. haha youre still lying

watch?v=2yCpovb1TVk&feature=re­lated

the oil flows no more or no less than the other two links. see what i dont understand... if the oil is supposed to be pouring out like you claim... why isnt the camera lens getting covered in it? answer that one sherlock

[robby844]

@arriviste2020 but then again you did say there were several links proving you right... i posted one that proved you DEAD wrong. so for the third time post the link you said was here

[wabash373]

@arriviste2020 As a mechanic for a short line in northeast PA. I agree that this engine should be putting out more oil then it is. The movie quality is not the greatest to be making a good judgement call on the amount of oil or the lack of oil. When we get our GP-9 running, I could take a video of the top deck and post it.

[arriviste2020]

@wabash373

No need to go to that trouble, I was merely noting an observation based on having overhauled a lot of these engines. I am not looking for a debate / argument or trying to ridicule whomever made the video. It would be nice to have an engine run as clean as that shown in the video, however I have never witnessed a unit in service which managed to do so. Your time and effort in making the video are appreciated.

[wabash373]

@arriviste2020 Roger, I myself have rebuild many 567A,B,BC,C and a few 645E and E3. There are couple FEEl also in that list. Do you know anything about electrical?

[salemcripple]

six exhaust valves, one intake? Kind of a weird set up (at least to an automotive mechanic's eyes)

[13Anko]

@salemcripple Its a 2 Stroke 4 (or 6, not sure) exhaust valves, the middle one is the diesel injector. (air)intake is going via the cilinder ports.

[TAPriceCTR]

@13Anko

since you know this is a 2 stroke, maybe you can tell me something I have been wondering about for a long time... because they are chamber injected (instead of intake injected like gas engines) 2 stroke diesels do not have the efficiency losses that 2 stroke gas engines do... why are most consumer diesels still 4 stroke? what is the advantage?

[arriviste2020]

@salemcripple

Valves are exhaust. Intake is through ports / gallery in the block. Blower pressurises gallery.:;))

[robby844]

@salemcripple only four valves. each spring is double sprung. the middle springs are to help keep the valves closed under power

[silicon212]

@salemcripple The engine has 4 exhaust valves on each cylinder. The two things in between the valves (that make it look like 6 valves) are the springs for the bridges - one for each pair of valves. The rocker arm in the middle operates the injectors. There are no intake valves - just ports that surround the liner at the bottom of the stroke, that are provided charged air from the airbox that surrounds the cylinders.

[ThePostal67]

Dang nice sound, wish my Prius sounded that way.

Rochelle IL railroad park where I go has a Electric Utility across the street and they had a tour a few years ago. First engine inside the door is about 100 feet long and 30 feet high, when it runs it shakes the ground outside. From a destroyer I believe, they have NINE engines..

[gladforkat]

it is a 4 stroke 

[woodscritter]

@gladforkat And you're Bambi's brother.

[Clydemontreal]

@gladforkat Nopp. a 2 stroker diesel..

[CLENCHEDCURVE74]

@Clydemontreal 2strokes dont have valves

[formidable38]

@CLENCHEDCURVE74 Yeah, these do!! The inlet air goes in through ports in the cylinders, those rockers operate the injector and 4 exhaust valves per cylinder.

[Clydemontreal]

@formidable38 : This is correct. And since it is not a "naturally aspirated engine", air has to be forced in cylinders at all times. Smaller engine (800hp to 2000 hp) use roots bloowers. Larger engines (2800 - 3800 hp) are equipped with a gear driven turbocharger. The turbo runs on the gear train until heat generated in the exhaust is high enough to "unclutch" and drive the turbo.

[thegreatkingdaniel]

@CLENCHEDCURVE74 Two stroke diesels have exhaust valves, except the 51 series Detroits.

[kamphwagon1]

@thegreatkingdaniel They called that one toraflow , it didn't last verry long it was mostly found in 21/2 ton GMC trucks , and was phased out with the 53 series, all the two strokes are gone from the road ,as far as I know Detroit dosen't have a engine for medium duty trucks anymore..

[jerry91a]

@CLENCHEDCURVE74 they dont have intake valves is what your trying to say right?

[PetrScorpio]

@jerry91a it must be a 4stroke

[ducati140]

@PetrScorpio

that is a 4 stroke, you can see the rockers

[bowtie4ever96]

@ducati140 its a 2 stroke those are rockers for the exhaust valves all gm/detroits have exhaust valves

[josippetrlic]

@ducati140 wrong wrong wrong, EMD 645 is 2 stroke engine, only EMD 4 stroke engine is 265.

[ducati140]

@josippetrlic it still confuses me, in a petrol 2 stroke there are no valves as sutch, and the petrol/oil mixture is forced onto the top of the piston by crank case pressure just after the piston has released its exhaust through the outlet port withch is higher in the cylinder., shurley if it has an exhaust valve it has to lose a firing stroke to release the exhaust gasses, im not being funny im curiouse as i dont understand.

[josippetrlic]

@PetrScorpio But it's not, this is EMD 16-645E and it's 2stroke engine.

[AntiVaccine2]

@jerry91a see my vids to learn herbs like kelp,kale,dandelion,coriander,­cayenne,pine,maca etC!

[RUTBERX]

es un motor de una locomotora encendido ayi seve como trabaja pistones

[needleonthevinyl]

Is this at idle speed?

[dapsapsrp]

Lovely music. Are those roller rocker arms?

[josippetrlic]

aaaaaaaaa 16-645E (I know it 16 trust me, 24 valeves are here), beautiful sound!!

[GordonFreemanD40]

it sounds like a four stroke, like the S50 or S60. (I know it's a 2 stroke)

[TruthDisorder]

5 million pounds of tourq

[UncleBubbles94]

Is that 6 valves per cylinder?

[psychotikpaisano]

@UncleBubbles94

No, its just a return spring between the valves

[kleetus92]

@UncleBubbles94 No... four, the center is the injector, and the spring in the middle of the outter arms is part of the whole assembly.

[GeneralG1810]

@UncleBubbles94 I know the reply is late, but no the center rocker is for the fuel injector. There are 4 evenly sized valves per cyl

[aussietraindriver]

@UncleBubbles94 4 exhaust valves per cylinder, one injector in the centre. air intake is via ports in the cylinder liner.
