The big Dieselhouse engine, starting and stopping.

[ehvee1]

The size is incomprehensible!

[ApolloWasReal]

What are the specs? Power, fuel consumption rate?

[Mitsugejl]

@ApolloWasReal Fuelcomsumption ca. 240 g diesel pr. kWh at 12 MW and that is approx. 2880 kg. of fuel per hour at nearly full load :)

22,500 (15 MW) effective hp,

8 cyl doubleacting.

Pistondiameter of 86 cm, stroke 150 cm, max rpm 115.

Roots blowers supply the engine with 1800 cubicmetres of scavenging air.

Exhausttemp 300 Celsius at 12 MW,

Lubrication with 40 tons of lubeoil 10 times a hour.

24,5 metres long, 12,5 metres tall and weighs 1400 tons.

Built in 1932, in use in 1933.

Enjoy! :)

[ApolloWasReal]

@Mitsugejl Thanks. That works out to a thermal efficiency of about 32.5% for Diesel fuel containing 46.2 MJ/kg. About what I'd expect for a Diesel engine of that vintage. Large modern marine Diesels can exceed 50% efficiency.

[Mitsugejl]

@ApolloWasReal It is running on fuel with a flammability of 10.000 kcal/kg and it is injected at 350-400 bars.

The engine is cooled by water from Copenhagen harbour by means of a heatexchanger. The lube oil is also cooling the pistons. The generator was supplied by ASEA. The crankshaft weighs 140 tons, the flywheel 80 tons and a complete piston with rings and connecting rod weighs 4,5 tons. The drivechain for blowers etc., weighs 700 kilos/meter.

[ApolloWasReal]

@Mitsugejl 10,000 (ten thousand) kcal/kg is equal to 41.868 MJ/kg, a little lower than my figure of 46.2 MJ/kg. That implies a slightly higher engine efficiency of 35.8%.

[Mitsugejl]

@ApolloWasReal Could it be beacuse the exhaust pistons also produces some power to the engine itself? The engine has two crankshafts, one for the pistons and one for the exhaustpistons and they are coupled together with the chain i mentioned before...

[ApolloWasReal]

@Mitsugejl Are you referring to the efficiency? The theoretical efficiency of any Diesel engine is determined by the compression ratio. Do you know what that ratio is? The actual efficiency is somewhat less due to heat losses through the cylinder walls, which is why larger engines tend to be more efficient - the volume to surface area of the cylinder increases with size.

[Mitsugejl]

@ApolloWasReal I am afraid that I don't know that. Are you an engineer perhaps?

[ApolloWasReal]

@Mitsugejl Yes, I'm an electrical engineer, with a side interest in energy and power. The compression ratio is simply the ratio of the bore volume with the piston down (when the exhaust valve opens) to that with the piston at the top (when the fuel is injected). The greater that ratio, the greater the maximum possible efficiency of the engine.

[Mitsugejl]

@ApolloWasReal Cool :) I was studying to become a marine engineer by means of part time e-learning but the government did put a halt to it unfortunately. Hopefully they will restart it sometime soon.

Combustion engine mathematics/physics is very interesting and complicated. I am a fan of large dieselengines and in my sparetime I usually fixes smaller, 1 cylinder marine diesels - just a hobby of mine :)

[Mitsugejl]

@ApolloWasReal It was the worlds largest dieselengine for over 30 years and was in constant use until somewhere in the 70'ies. It was used as an emergency generator at H.C. Oersted power plant until 2004 and is now retired from active duty and is used solely as museum engine. Engine no. 2000. The pistons is about 3 stories high, a reserve is stored in the facility but has never been changed in the engine 80 years of operation.

[jaydizzay]

throttle response measured in minutes

[cameron947]

So how exactly do those huge engines work? Because by the look of it there's no rotating crankshaft.

[RDELAPLAZA]

it starts spining using compressed air, I can hear the hissing of the compressed air leaking... but when ( at which minute:seconds ) it starts? I mean it transfers to diesel operation ?? I can not hear a difference during the whole cycle, when diesel kicks in????

[Mitsugejl]

@RDELAPLAZA That would be a leakage in the bottom of some of the cylinders. The hissing noise is the actual compression cycle you are hearing because this engine is doubleacting - combustion at both top and bottom of the piston to boost power, just "like" an air cylinder. The seal gets worn faster because the connecting rod is passing through the exhaust piston - the connecting rod is moving up when the exhaust piston is moving down and vice versa and thereby doubling the wear :)

[Leonardo9262]

i like that engine for my motorcicle

[Gohot229]

Boy look at all that scrap iron, and at 13 cents a pound, I'd be rich for a month. Probably take a big torch to cut it up into manageble pieces to send to China to melt back into Harbor Freight stuff.

Just kidding, it's quite an achievement in engeneering

[pingusiapingusia]

where is it???

[Mitsugejl]

@pingusiapingusia DieselHouse in Copenhagen :)

[pingusiapingusia]

@pingusiapingusia WOW ,THANKS

[crsvky28]

what does it do? just run or does it have a purpose?

[984francis]

Built by the English in 1933. I'm English and I am sorry to say that even given the we recently built a new 4-6-2 steam locomotive (apart from the boiler, that came from Germany), I doubt we could build this now. WW2 and servitude to America has killed the English sense of "can do".

[bigmikeherring6332]

it is a beautiful peace of engineering

[dx80cruiser]

when does the VTEC kick in? :) LOL

[SakoTGrimes]

@dx80cruiser at 12 RPM

[dieselducy]

Now THAT is a diesel engine!! I work for the railroad and compared to that, our engines are like a little 4 cylinder :)

[jib48]

Hi Jeroen , ik weet dit toch ook man . maar ik vind je reactie wel wat heftig . Ik bedoel mijn reactie hier eingelijk allen maar als grappig , Maar kennelijk niet aangekomen .

[jib48]

Hi Jeroen , ik weet dit toch ook man . maar ik vind je reactie wel wat heftig . Ik bedoeld mijn reactie hier eingelijk allen maar als grappig , Maar kennelijk niet aangekomen .

[jib48]

wat een kut ding geef mij maar MAK of MAN of Deutz of MWM, wat een kut motor is dit zeg , potverdorie nog es aan toe , vind het helemaal niet leuk . !!! Wat ee stom ding zeg , hij heeft er nu al genoeg va , hoor je dat ook , he he wat een rust , stom ding ! LOL

[geizzie]

@jib48 Deze reaktie is een duidelijke afspiegeling van jouw intelligentie.

[jeroen1843]

@jib48 Arm ventje. B&W is nu een gedeelte van MAN. Denk je nu echt dat die Duitsers dom zijn om 1 van de meest gerenomeerde motor fabrikanten ter wereld te kopen? Blijkbaar kan je niet eens denken laat staan Googelen......

[spencnaz]

Is this a double acting diesel?

[TurbinePower69]

@spencnaz Yes.....it is.

[skabsracer]

@spencnaz yep

[penije]

It uses allmost 100 liters of Diesel pr. 10 min. How much that is in Gallons, i dont know. But with 22.500 bhp its probely not much...! But it can with just 115 rpm, produce about 15 MW (15.000 kW), so i think that, when everything ells not working, 100 liters Diesel pr. 10 min., is ok..! The engine weight is 1.400 Ton (1.400.000 kg), is 24,5 meters long, 12,5 meters high. That`s about 3 storages high...

[kermitttt]

like steam engine

[TheLightningStalker]

I don't think it's supposed to be hissing like that.

[4freespeech]

Probably burns 100 gallons of diesel per second.

[starscream1985232]

ENGINE SWAP FOR MY TACOMA!!!

[slovakmath]

so (given the amount of diesel this uses to run) is it more efficient to use that diesel to run an engine to turn a generator (which is what is shown) or to rather burn the diesel and heat up water to create steam to turn a steam turbine to produce electricity (similar to a coal fired power plant, except using diesel for fuel)?

[robby844]

@slovakmath most of the places you just mentioned use used motor oil to fire the boilers.at least in america they do.

[slovakmath]

@robby844 that is trivial regarding the question. I am curious as to which is more efficient, or rather which allows more heat to be lost?

[robby844]

@slovakmath the turbine produces more heat and by products than the generator system

[curtbarile]

Please do not let Obama give this engine its next oil change, He thinks engines this big need liquid glass.

[infinity3jif]

i would'nt want to be around this thing when it throws a rod

[skabsracer]

@infinity3jif - running since 1933 - wont start throwing roods by now !

[fortress1133]

Shutting it down sounds like putting a dragon to sleep... Not that I know what that sounds like. LOL!

[ivankoran]

so what kinda fuel consumption does that thing have?

[scotty2307]

I believe that the funny sound, ie. fading in and out, is an artifact of the microphone on the camera. In reality I would think the sound is smoother. Search Dieselhouse Copenhagen on YouTube and you will find a good video with an explanation of the engine by the curator of the museum along with a start, run, stop clip with good sound.

[trainman071]

damn thing has a unique rhythm

[douro20]

This engine was used almost continuously from 1933 up to the late 1970s and once powered the entire city of Copenhagen. The engine, model DM884WS-150, has eight cylinders, has a 840mm bore and 1500mm stroke, and produces 15MW of electrical power. It has multiple total-loss oilers and a system for cooling the main crankshaft oil.

[WizzleThump]

smart motherfuckers without computers made that.

[Ronfox5818]

@WizzleThump I agree with you . i spent 28 yrs working with diesels. Most kids today need a computer to tell them what to do..  HAAAAAAAAAAAAA

[ismaelkhan]

@WizzleThump damn right man, today we have allsorts but in those days they really knew how to use their heads.

[Blade565]

sounds like its broken

[douro20]

This is a double-acting engine- there is one piston in each cylinder and combustion occurs at the top and bottom of each piston. There is a piston for this engine on display which is intended to be used as a replacement. To my knowledge, there has never been a piston replacement in this engine.

[cvrocustomrides]

i DEFINITELY have to go to that museum before i die.

[SthealthRaider]

WTH IS That engine!>>!!

[TheJabol82]

beautiful engine, really sensational!!! Super, super, super machine :D !!!!

[generalen33]

It uses 8.400 liters in one hour....

(140 liters pr.minute...)

[rokafulla]

how much diesel would this use an hour! what an engine.

[6V92TA]

id hate to change the oil on that thing.

[robby844]

it burned it so much that all you had to do was add to it.

[6V92TA]

lol...sounds kinda like my car

[MrMarcelB]

Gearhead 156 probably around 90 to 110 rpm at full seaspeed depending on size of ship speed around 13 to 15 knots.I have worked on similar type of engine a Doxford J type Great when working properly a nightmare if you breakdown.

[jabegren]

Hello Mr Marce IB

B&W= One Piston acting on bouth side of the piston.

Doxford= two opossite working pistons

[MrMarcelB]

Yes I know the differance between a opposed piston (Doxford) and single piston (Sulzer--B@W--MAK) The best engine I ever worked on was a Sulzer 4RLB 76 a big honkin 4 cyl.enginethat required reg maint.according to the manufactuers specs.After the initial run in we did pistons every 10,000 hours and so on.

[GearHead156]

rpm?

[animebsd]

imagin overreving this thing and blowing it !!!

[GearHead156]

hahahah holy carnage!!!!!

[6V92TA]

it'll take out the building. Can you imagine watching a connecting rod shoot thru the block?

[steelerfreek007]

i want one in my 97 ford f-150

[victor4444]

Maybe theres room for a Ford in the crankhouse.

[tpvalley]

I believe these r double acting like a steam engine, in that each con rod pushes and pulls, combustion happening both sides of pistons!

[simonspiers]

You would never stall it at the lights lol!

[lmogden1]

where is this engine located and when is it open to the public

[victor4444]

Hi there read the info i have provided.

theres also a google map entry for the exact location.

I dont think they move the engine arround.

[MF11283]

@victor4444 really you dont think they move it?? I would have guessed 2 or 3 guys pick it up and pit it in the back of their toyota pickup and drive it to a new location no problem

[victor4444]

@MF11283

Wow, i would like to see those guys ;-)

[electricshockproof]

@victor4444 ...And that truck!

[listepikster]

it is indeed open to public. and every other sunday it is started.

its located in Copenhagen Denmark. its a diesel museum called diesel house.

[greywolf45]

@lmogden1 Capitol city of Denmark i believe. This engine is still used to generate electricity when the grid goes down, so that's why it's so well maintained. This engine is part of the emergency power back-up for the power grid.

[Squarerig]

bugsier5 danke fuer die Information.Aber meine Frage waere.Ist dieser Diesel Lufteinspritz-Blast oder Direkt/Commonrail-Solid

[jabegren]

Common rail system developed 1976.

This engine is fabricated 1933.

You better use your " brain box" ...

[johnsenkenn]

Do you use your brain box, what size is it.

[Squarerig]

Is this engine blast or solid?

[bugsier5]

two stoke dubbel acting (two pistons pro cilinder)engine with roots blower....

[johnsenkenn]

@bugsier5

Two pistons per cylinder......double action.

[jabegren]

Wrong!

It is one piston per cylinder, acting on both side of the piston (top and bottom combustion in the cyl)

[johnsenkenn]

Right....

That was what I believed it to be.

[derneuschooer]

woh i´ve nerver seen that before, that must be sone kind of special system !

[fkeyboard]

I love the sound. I can listen for days.

This reminds me of my days when I was an officer in the merchant navy. Good old days.

[Hellcleaner13]

that's one big engine
