- Air-blast injection Diesel built by Grazer Waggon- & Maschinenfabriks-Aktiengesellschaft (Graz, Austria)to MAN drawings. Lighting plant for a hospital installed in October 1904, later served in a sawmill until compressor damage by lube oil explosion.
16 hp at 235 rpm
bore 215 mm
stroke 340 mm
heavy flywheel for lighting
110V dc Crompton dynamo and switchboard
The sound of these engines is hypnotic
the men who designed and built that engine must have been very proud of their achievement at the time, and rightly so.....an engine like this was to the industrial revolution what einstein's theory of relativity was to physics at the same time
It looks like it can run like this for years! those low-rpm diesels are amazing machines!
Middle rocker is air start. The starting lever moves an eccentric which either engages the starting or the fuel injection rocker: Lever down: start-lever up: injection system engaged, engine running. Fuel injection rocker is barely visible since hidden in the clip by the camshaft.
So many intricate parts--it must have been exquisitely expensive when new.
The engine is running on air blast. The fourth rocker is not visible on this videoclip, it is hidden between camshaft and cylinder head. Lift of injection needle is about 1 mm, this is the reason why you hardly see it lift. Look closely at 5:56. Injection timing is -5/+35 degrees crankshaft rotation. This protracted injection of fuel over 40 degrees is one of the reasons why these engines run so smoothly.
An even when looking for the lifting of the injection needle at correct time, one must be understand that it is moving upwards instead of downwards like the intake and exhaust valves. If looking for downwards moving, one misses it.
it is where all machines began i think.....1904 nice date to remember during its time maybe its expensive for and today it maybe out of date but still its more expensive i think this machine needs a birthday for its 100years of service
Amazing machine...I noticed by one of the step plates that it had a built in indicator for measuring performance and diagnosing problems..
The air compressor-being a specific feature of the Graz built engines- is not driven by links from the connecting rod as in the original MAN design, but rather by belt from a large pulley between engine and flywheel. Since the bottles are difficult to keep tight for months, the air compressor is driven by an electric motor (=cheating). The installation however allows to take off the belt to the motor and connect the compressor to the engine by belt the same way it was set up in 1904.
Wonderful engineering. I congratulate those who have restored these machines. Hmmm, pity to see those gloves though!
Simply fantastic! Thank you so much for explanations down below. Also thanks a lot for restoring, making, taping editing uploading and sharing.
I think the middle rocker is a compression release.
the roller rockers are cool!
the cam is as big as the crank on most modern cars...
Very Interesting, Looks like it's brand new. So clean and sparkling. Thx for showing it, and showing the exhaust also.
I saw the middle cam follower and said "Ha it has VTEC" and then I thought about what I just said and realized this was a multiple ton diesel engine.
Such a wonderful piece of engineering when it comes to efficiency and reliability nothing rivals diesel. Just curious how long does it take to get it running?
Well, it wouldn't normally because the engine's internal air pump would take over. But in this case, as the guy who posted this video said, the belt which drives it has been disconnected from the engine.
thnx a lot ... really a great machine .
Really glad that you restored it to its original luster.
It's really a pleasure to hear her run :)
It would be interesting to know which engine is really the oldest operational and actually running diesel as per 2009.
This video shows that there is nothing new in this world. Roller rockers.....
Great video!
THE BEST QUALITY VIDEO ON UA-cam! HISTORY CAN, AND IS AWESOME!!
Very few i.c. engines run sweeter than a well adjusted blast injection diesel built after 1902 or so. No reason to commit suicide. You should read Lyle Cummins History of the Diesel Engine.
In rememberance of Rudolph Diesel, who died penniless falling from a Diesel powered ship at sea.
What you hear is a recording loop: noise in the foreground is intake air, remotely you hear the ding of the compressor first stage intake valve. Otherwise the engine is very quiet, somewhat like a steam engine.
God bless you and Rudolph Diesel!5*This is art and science Way ahead of its time.Thank you!
@partsproduction No:" Diesel´s engine from conception to 1918". A bible for those interested in the early air blast engines. Possibly out of print but available from Amazon. By now there are more videos on these engines on youtube: MAN airblast diesel/MAN Einblasediesel/MAN DM 12
es ist schön, wenn man als grazer auf solche maschienen bzw videos stöst!
@RustyCarnahan I think its for the air that gets into the cylinder to start up! i didnt see an starter engine so it must have started on compressed air
I think the second oldest is at Internal Fire and they also have a replicar of the oldest (I think!)
Yours is prety much identical to those though.
Just a quick question. Someone made a coment that the air equiptment should be stopped once running but doesn't the engine relly on this for Air Blast?
All the best,
Phill.
Four cam lobes. From left: intake, starting valve-disengaged when running, air blast needle -rocker arm hidden by camshaft, exhaust.
They ought to cut out the starting air compressor once the thing is started; its sound is very dischordant compared to the diesel itself.
all those lovely cams!
Incredibly perfect rebuild!
Chapeau!
So is this the oldest running diesel engine in the world? I would like to think so!
Very nice, I'd love to visit this engine.
wow! its almost like a steam engine! so quite and slow running! thak you!
Wow, it even has its original comressing equipment too! Amazing machine. Nothing like the diesels in VW's now! LOL
Kind of ironic that a German engine is driving a British dynamo when you consider it was built 10 years before World War One.
Love that German ingenuity! Great and beautiful machine!
Is the engine running with solid injection instead of blast injection, the injection valve do not seem to be operated, many blast injection diesel engines were converted from blast
injection to solid injection later, because of high pressure danger and the old unreliable system.
such work just to get it running..never complaining about how long it takes glow plugs to warm up again
@dieselfritz "Internal Fire" by Cummins, is that what you are referring to?
Das ist ja mal ein absolt herrliches Video von einem tollen Motor.
Vielen Dank für die Aufnahmen und 5*!

What's the middle rocker for?
Logic tells me fuel injection, but I only saw it being used for startup. What am I missing here?
great video... and great piece of art you have there
Rudolf diesel! Thank you!
Hervorragende Restauration. Ich habe Originalfotos dieses Motors aus dem Jahre 1991. Kann ich ihnen gern senden wenn sie mir ihre Kontaktdaten senden.
Gerne und danke! fwbusch@web.de
Could you please tell me the name of the hospital this engine worked at?
Barmherzige Brüder, Graz
Ein super Video mit interessanten Details.
Dafür gibt es natürlich 5*.

From what I know it governed the engine speed.
No, but it's only a couple of years of!
Do you use the dynamo? If you do, What do use it for?
This is what powered the first USSR space craft.
that was an awesome vid. thanls for posting
2 or 4 cycle?
at 5:13 what is the middle cam lobe for?
Believe it or not, the engine was recovered from a crashed flying saucer.
Starting valve?
Wonderfull,thank you very much.
4:57 very funny, it clarifies how slow the engine is running
love the sound
It´s very nice to see it
How much,please?
@dieselfritz Wow that is very slow for an engine.
overhead camshaft!
I have to have one. I can make the witch down the street choke.
Please look at the comment on the question by Shaun928 one year ago.
RPM is 195.
4:58 I like it
Bitchin' erotic can technology be....
Whadda wonder of a videoclip, fella! Thanks for sharing it!

Great people who invented such marvels,
Best brains given by Allah.
Very nice
Allah had nothing to do with this. It's German. And the western countries built all the great stuff and made all the discoveries that you prosper from today. From Ancient Greece and Rome, to the USA of today. We made it, you love it. Stop hurting people before we exterminate you. Vermin.
Nope. MuHAMad didn't make shit but war. And that fucker isn't anything but a figment of your small imagination... Sorry. You lose.
Steven King western like you can just make an ass fat but nothing. Pig eater behave like pigs
Ok. Sounds good tough guy. You'd piss in your potato sack if you saw me in person. Punk.

So your great 'allah' thinks that it's good to demean people by calling them nasty names?
