- Dieser in Schweden in Lizenz gebaute DB 605B
kam nach seiner Überholung im Sommer 1992 in Baierbrunn bei München auf den Prüfstand.
Sehen und hören Sie, wie der DB 605 anspringt und dann bei verschiedenen Drehzahlen seinen Prüfstandslauf absolviert.
Bei der Aufnahme kam es in dem geschlossenen Prüfstandsraum zu Lautstärken bis zu 140 Dezibel.
Auch hört sich der Motorensound durch die Schallreflektionen im engen Prüfstandsraum ganz anders an wie wenn der Motor in einer Me 109 eingebaut ist.
Wäre eine Bild- und Tonaufnahme von der anderen Seite möglich gewesen hätte man auch das typische Pfeifen des Laders hören können.....
In my opinion the DB 605 was the finest aero engine ever built. A true work of art. They sound so much more an engine than a Merlin or Alison with that thundering growl. I have always found it amusing how fans of Allied V12 engines love to criticize the DB engines on the face of them running low compression and low octane fuels. When the RAF examined a DB 601 they were confused as to how a four valve V12 could get correct cam durations with a single cam shaft! They also expressed misgivings as to the efficiency of the automatic torque coupled boost system and direct injection system that was standard on German engines. In the end a full report was made to the air ministry recommending similar engine systems be introduced to British aircraft! The truth was that the Germans had really got to grips with engine technologies in the early thirties and were some ten to fifteen years in advance of what the British and Americans were using.
Yeah, the first Spitfires also had the problem that the engine was turning off when pushing negative g forces. Just the Merlin 45 fixed that issue. The Rolls Royce Griffon was able to keep up with the 605, but years later.
So why did the first 109 fly with a Rolls Royce engine? Because the Germans didn't have an engine available. British engines were very advanced, as were american ones. The truth, as I see it, is that German, British, and American engines all had good technologies. I have less knowledge of Japanese engines or Russian ones. The Merlin had four valves per cylinder running on a single cam per bank, so no advantage with the DB601/5 on that. I'd suggest that in terms of performance, you should judge an engine on it's output relative to weight, fuel consumption, and physical size. Reliability and cost to manufacture are separate issues not directly related to performance.
Interesting comment on DB605:
"The inverted engine did pose problems with oil supply and consumption. The British sent a team to Germany immediately after WW2 to investigate the German engines and speak to German engineers. The British team comprised men from the Ministry of Aircrat Production and all the British aero engine manufacturers (including Armstrong Siddeley Motors, Bristol Aero Co., D. Napier & Son and of course Rolls Royce). They produced a report, 'Comments on Visit to Germany, July 24th 1945 to August 12th 1945'. In it they recorded that Daimler Benz engineers would have preferred an upright 'V', but the inverted layout was a requirement of the RLM (actually it predated the RLM, back to 1928).
They made the point that it was very difficult to get even oil consumption as the rotation of the crankshaft caused one bank to get more oil than the other. It's why the compression ratio is lower on one bank than the other.
Cheers
Steve
Edit: Quote from report:
“With the inverted engine, they said it was very difficult to obtain consistent oil consumption and due to the rotation of the crankshaft one cylinder bank got more oil (spray) than the other. This oil got past the pistons into the combustion chambers and reduced the anti-knock value of the charge. For this reason the engine was built with a lower cylinder compression ratio on this bank than on the other.”

Good engine I agree but it doesn’t mean Americans or the brits couldn’t build such an engine. They just chose a different route. Double supercharger is a bit less efficient as altitude changes but far easier to mass produce than the fluid coupled DB 600 series.
In many, many ways, the narrow focus on technical aspects are what made Germany lose the war. Technical genius but strategical idiot.
Another example, germans made the Artillerie pieces mighty fine for accuracy, expensive, hard to produce. But Americans simply invented computer to calculate the trajectory. If you ask me, I choose the latter mentality any day. But some of the technical achievements like this DB605, interlocked wheels on german tanks are so on, are good to look at too.
Germans were ahead at its time on everything! Jets, IR night vision, assault rifles, tanks, rockets, radio navigation missiles, Radar... EVERYTHING. And allies tried to made them the evils from europe because hitler wanted war after humiliation of germany in ww1.... 6 bilions!!!! buuuh!!! hahaha
Every single of these engines
The flames are always blue
I have no words
How beautiful
In order to achieve maximum performance, a mixture of water and methanol can be injected into the engine. That is why the flames color changes from blue to red.
Also blue flames come from having a more complete combustion
That start up sends shivers down your spine
Astonishing to me that this technology is almost 100 years old now, yet it still seems like an absolute feat of engineering just to hear the sounds of this engine.
Deutsches technisches Denken ist heute noch Lebendig!Danke.
I need to buy myself a Dobly surround system.. Could listen to this all day :)
Germans be proud. You earned it. Inverted v12 needle-roller bearings all round, sodium valves, max power at all altitudes running on 80 octane fuel. As RAF Capn Eric "Winkle" Brown stated, having flown near all Luftwaffe aircraft- including bf109K, me163 and me262, and Germany having the ONLY supersonic wind tunnels in the world: "They were at least a decade ahead of us". 80 Octane is essentially diesel.
I have to tell you!I grew up on an Airport and several years ago I did a apprenticeehip as an mechanical engineer. Now I´m working as an aircraft mechanic for the Eurofighter at the Bundeswehr and I have to say that this is a real engine :)This Engine is absolutely awesome and I could listen to this Music all day ;) This engine is simply said: Singing steel.Engineering at it´s best.Tank you guy´s for this Video.
I have to agree that the DB-605 is one of the best sounding of the big V12s. Daimler gave it a "hot cam" and you can hear that cam loping at idle. More of a growl in the throttle than the Merlin. There are multiple firing order combinations in the V12 and they can give each engine a unique song. There should be one or two Jumo 211s and maybe a Jumo 213 coming to life in a few years so there can be a comparison with those.
In my little archive I have some original sounds of the JUMO 211 and it is different to the DB 601 or 605.
The main reason seems to be the special sound of the Jumo-charger.
The firing order, valve timing, exhaust shape make each engine sound unique. Maybe you could put the Jumo 211 recording on RUclips? I look forward to new restorations bringing these engines back to life. I am pleased to see that there are three Tempest projects working to get an ultra-rare Napier Sabre into flying condition too.
I have the JUMO 211-sounds both on MC-Casettes and on VHS-Tape with the problem to bring them to the computer.
May be it will function in June or Juli.
Great. I would love to hear them. A 211 was rebuilt to running condition (I think in Germany) years ago but I don't know if anyone filmed or recorded it. Someone is working on a ground-runner and there is also a flying project but those could take years to finish.
*Das Teil röhrt ordentlich!*
A powerful engine without a doubt, as it also showed during the war.The Germans can make good engines, in cars, ships or aviation.
Es ist einfach super .Guter Lauf
The moment you see how the camera shakes you know this engine means business.
Just like this video, I too was made in the summer of 1992.
Music to my ears.. 😁
El sonido súpersónico más dulce de voz femenina de todos los tiempos es el Daimler-Benz DB 605 A1 del messerschmitt Bf 109 G6
Die Flammen in den Auspüffer, sehr psychedelisch.. Sehr gut.
Soy RUclips allows porn now?
Yup
Mechanical porn
Thank you for the upload! The sound is pure harmony.
Listen to a Merlin engine and hear a beautiful symphonic sound. Listen to the Daimler Benz engine. The recipe for recreating this sound is to start with a Merlin. Put in a racing camshaft, jack up the compression, and then garnish with the shriek of 1000 tortured souls that is the DB605 supercharger. It is simply the most pure and sinister sound in the universe. Being attacked by something with this sound would make me curl up in the fetal position on the floor and cry like a little baby. Any exposure to this instrument of war will permeate your soul and imprint itself there forever. It moves a person like nothing else. Non-aviation people who stumble upon it at an air show can be talkative and laughing around all the rest of the aircraft, but when they lay eyes on the 109, all go quiet, not knowing but feeling this unstoppable force that is the Bf109G.
1:57 and that whistle... that damn whistle...
Motor impressionante, até os dias em que estamos!!
verdade, pretendo colocar isso no meu trabalho de historia
Very cool, love that sound.
So... that's how the Maus would sound? That makes me want a restored Maus even more
A true Benz
A true work of art... Well after the war, a chief mechanic was telling his crew to be careful not to damage a DB605A crankshaft during disassembly, because they wouldn't be able to duplicate it with the machines they had at the time...this was in the 80's. The video with this info can be seen at around the 18:35 mark. Here is the link ruclips.net/video/cIFCQuiZM6Y/видео.html
Not on 18:35 BUT 19:51
Absolutely beautiful.
Like Kristof said, singing steel. That sound it makes after the engine cuts in.
Hard as a fucking rock son.
One must not forget that this was a 35.7 Litres compared to the Merlin 27 LItres. There is a lot of difference in the exhaust note as the power ejected through the exhaust is higher. I would say that they are both excellent engines for their time and they represent the best that the piston engines could achieve. In fact, they were so good that the men who designed them could not imagine that there could ever be a better engine................ but they do not expect that someone will come up with a simpler engine with " one moving" part which would turn out to be an engine that one can keep increasing in size as since there were no reciprocating parts, the metal was not subjected to a high punishment as some parts in a piston engine.
Those piston engine men......... who made the best piston engines could not ever believe that anyone could do any better than they did and they even gave Frank Whittle a very hard time.
With all those moving parts, the piston engine gives more romantic teamwork of parts working together............but let us face it, the jet engine is simpler and more elegant due to its simplicity and great wonder about the function of that compressor and the diffuser which need some clever minds to get the curves correct to achieve the desired functions.
I fully agree.
You're definitely right but I think piston engines are significantly cooler because of the unreasonable complexity. Just a subjective opinion
I fully agree, greetings from Germany!
Love this machine!
Put the db 605 in a car, Allison’s and Merlin’s have been put in hot rod like rolls Royce and such, just imagine a classic Mercedes sporting this thing, now that would be bad ass
I agree, but sadly the DB's are so rare now, that will probably never happen. Crazy no?
Put it in a Olds Toronado.
Wow.🤠👍
Excellent moi! 🌠🛩️
Yeah i like the db´s ,too.
the merlin would have been useless to germany,
but after all, necessaty is the mother of invention, the daimler benz is very german in it´s philosophy, they couldn´t match british supply advantages, there engine would be more powerful and lighter, so they used bruteforce, further, the inversion allowed for better streamlighning and maintainence the larger displacement gave it more power with lower octane fuel, improved by the best fuelinjection systems in the world, one of the main reasons for it´s devellopment was to cope with the synthetic fuels. And after that supplemented with NOX and MW50.
As the germans didn´t consider high-altitude interception capability a necessaty at that time the 600 series mostly ran a continuously variable speed on a single supercharger with better performance than even some 2 stage systems.
at the end of the war germany had the highest flying operational fighter, the fastest operational fighter aswell as the overall highest flying aircraft, that held it´s record into the 50´s by virtue of the superb jumo opposed piston 2-stroke diesel, force-fed with higher pressure than any petrol engine could endure. jeah eat your heart out, before jets were practical the bf 109 was technically the fastest interceptor in the world, in is later iterations
how can the exhaust can output the big blue fire like that?
+Sugiharto Wibowo Oxygen mixing with the exhaust for complete combustion. Or lean mixture.
Sounds like a damn nitro hemi at idle
Das ist toll.
That inverted V sound
This is the apitamy of something manly/badass! Im so hot rn i love engines so much.
Man hört das Turbo-Pfeifen, wenn auch nur leise :)
Ja, wunderbarer Sound, ist aber ein Kompressor.
❤️❤️❤️
Deutsche Wertarbeit! 😺👍😎💪💙🇩🇪💙🇩🇪💙🇩🇪💙🇩🇪💙🍀🐺

ÓTIMO MOTOR
One cylinder missing in the start? What fuel?
are these all salvaged engines from crash sites and from barn finds? or are they somehow manufacturing them?
Just noticed what you see if you make the screen big and then need to reduce it...look at the button you have to press lol...
Robert Elmo yes the iron cross, I stare at it every time I need to leave fullscreens
Esteban Singh That’s not an iron cross lol
@@Wehraboo-fi9vm it's the inverted "Balkenkreuz", based on the Iron cross, which is used since the Teutonic Order in 1190.
Hallo Herr Münter, ich suche eine Person wegen Nachfertigung für diesen Motor. Wie kann ich Sie kontaktieren ?
Hallo Herr Laugwitz,
ich habe mal gelesen, daß es bei der Firma FLUGWERK Überlegungen gab, den DB 601 neu in einer Kleinserie zu fertigen.
Da müsste mal mal nachfragen oder bei der Fa. Dachsel in Baierbrunn, wo der DB 605 seinerzeit überholt wurde.
Ein Ansprechpartner wäre eventuell auch die Fa. Dirk Bende. Die haben schon Argus-Motore für den Fieseler Storch überholt und es gab da den Versuch, einen JUMO 213 zu restaurieren.
Meier Motors in der Freiburger Gegend könnte eventuell auch was bringen.
Herzliche Grüße
K.H. Münter
Third cylinder in on this bank took some time to start firing properly watch the flame. But it cut in, possibly fouled plug, it cleaned up though. I wonder if plug fouling was common, it is and upside down v12, the crank is at the top of the engine? So the cylinders may suffer the same problem a radial engine suffers with gravity taking oil past rings when static. On radials you have to manually walk prop blades through clear oil from lower cylinders? Great demo of engine running!w
It is as you must know, a dry sump engine with a scavenging pump and external oil tank. There is very little oil to “leak into cylinders” past control rings. Same setup in radial engines but the design of crankcase allows some oil pooling to use gravity to foul lower cylinders.
Was macht den der so an Leistung? Also PS und Drehmoment
Tolle Aufnahmen. Sehr beeindruckend.
Ich wußte gar nicht, daß die Schweden diese Motoren in Lizenz gebaut hat. Von wann bis wann haben die Schweden das gemacht und wo wurden diese Lizenzmotoren dann verbaut?
Daumen hoch! :)

SAAB J21 verwendete den DB605
Weiss jemand mit was für ein Kraftstoff der Motor arbeitet
Great engine! What is the airscrew reduction gear ratio on this engine?
+ LM It can very for sub-model but typical is 0.594 to 1.
@@FiveCentsPlease Thank you very much! I am fascinated by German engineering. Especially the aircraft industry from WWII
soo...this was supposed to push a 180t Combat car?
Aye, 2 of those.
0:16
Whats the sound of the beggining of the start procedure?
The flywheel. They use it to store kinetic energy from an electric starter. Such big displacements were impossible to start instantly like a modern car.
Comparatively that Benz engine starts very quickly. Most sputter and spit at first.
Super, interessant auch, das die Deutschen den Motor "Kopfüber " in Flugzeug einbauten, anders als den Merlin Motor, warum wohl, wegen des Schwerpunktes? Gruss Tom
Kurbelwelle oben und Zylinderköpfe unten ergibt für die Flugzeugführer bessere Sicht bei den Einbauverhältnissen einmotoriger Flugzeuge, so die damalige
Auffassung. Die ebenfalls kopfunten eingebauten V12 Jumo 210, 211 ff wurden zuerst auch in größeren Stückzahlen in der ebenfalls einmotorigen Ju87 verbaut.
Für die Unterbringung von durch den Propellerkreis feuernden Waffen ergaben sich wohl auch Vorteile.
Man konnte im Feld leichter die Ventile einstellen und Kerzen tauschen
CV ?
Einer zündet nicht.....😮
turbocharger？
Lader? Wohl eher Kompressor 😉
Und der läd den Motor nicht auf?
Put it in a farm tractor.
Inverted V12....
yeeeeeeeeeeeeeeeessssssssssssssssss mmmmmmmmmmmmmmmmmmm
In ur face rolls royce and merlin!!!
