1904 air blast injection Diesel engine 

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.

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

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.

It looks like it can run like this for years! those low-rpm diesels are amazing machines!

The sound of these engines is hypnotic

So many intricate parts--it must have been exquisitely expensive when new.

THE BEST QUALITY VIDEO ON RU-vid! HISTORY CAN, AND IS AWESOME!!

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 :)

Very Interesting, Looks like it's brand new. So clean and sparkling. Thx for showing it, and showing the exhaust also.

God bless you and Rudolph Diesel!5*This is art and science Way ahead of its time.Thank you!

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.

Simply fantastic! Thank you so much for explanations down below. Also thanks a lot for restoring, making, taping editing uploading and sharing.

This video shows that there is nothing new in this world. Roller rockers..... Great video!

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.

Incredibly perfect rebuild! Chapeau!

Kind of ironic that a German engine is driving a British dynamo when you consider it was built 10 years before World War One.

all those lovely cams!

In rememberance of Rudolph Diesel, who died penniless falling from a Diesel powered ship at sea.

Amazing machine...I noticed by one of the step plates that it had a built in indicator for measuring performance and diagnosing problems..

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...

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

es ist schön, wenn man als grazer auf solche maschienen bzw videos stöst!

Das ist ja mal ein absolt herrliches Video von einem tollen Motor. Vielen Dank für die Aufnahmen und 5*! Bidone

Wow, it even has its original comressing equipment too! Amazing machine. Nothing like the diesels in VW's now! LOL

wow! its almost like a steam engine! so quite and slow running! thak you!

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.

Wonderful engineering. I congratulate those who have restored these machines. Hmmm, pity to see those gloves though!

Rudolf diesel! Thank you!

great video... and great piece of art you have there

Four cam lobes. From left: intake, starting valve-disengaged when running, air blast needle -rocker arm hidden by camshaft, exhaust.

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.

Love that German ingenuity! Great and beautiful machine!

that was an awesome vid. thanls for posting

@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

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.

This is what powered the first USSR space craft.

Wonderfull,thank you very much.

From what I know it governed the engine speed.

Ein super Video mit interessanten Details. Dafür gibt es natürlich 5*. Gruß Bidone

It would be interesting to know which engine is really the oldest operational and actually running diesel as per 2009.

Very nice, I'd love to visit this 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?

4:57 very funny, it clarifies how slow the engine is running

They ought to cut out the starting air compressor once the thing is started; its sound is very dischordant compared to the diesel itself.

love the sound

Believe it or not, the engine was recovered from a crashed flying saucer.

It´s very nice to see it

overhead camshaft!

@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

such work just to get it running..never complaining about how long it takes glow plugs to warm up again

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.

So is this the oldest running diesel engine in the world? I would like to think so!

No, but it's only a couple of years of!

4:58 I like it

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.

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.

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?

@dieselfritz Wow that is very slow for an engine.

Bitchin' erotic can technology be.... Whadda wonder of a videoclip, fella! Thanks for sharing it!

RPM is 195.

@dieselfritz "Internal Fire" by Cummins, is that what you are referring to?

Hervorragende Restauration. Ich habe Originalfotos dieses Motors aus dem Jahre 1991. Kann ich ihnen gern senden wenn sie mir ihre Kontaktdaten senden.

Do you use the dynamo? If you do, What do use it for?

Could you please tell me the name of the hospital this engine worked at?

สุดยอดมาก

2 or 4 cycle?

How much,please?

at 5:13 what is the middle cam lobe for?

STEAM PUNK!!!!!!

Starting valve?

Great people who invented such marvels, Best brains given by Allah. Very nice
