Ich liebe dieses Video, Respekt vor dem älteren Herren. Dieser Motor ist für mich die Königsklasse der Gegenkolbenmotoren, das Ding wurde ende der 30er Jahre gefertigt! War leider zu träge in der Drehzahlregulierung. Junkers hat zwei Ju 52 mit diesen Triebwerken an die Lufthansa ausgeliefert.

the sound is amazing, so quiet and smooth. how the lubrication system works on this engine? via pressurized oil pump, and oil flow passages inside the engine ?
Starts great. Sounds great. The Junkers 205 was the result of about 20-years research by Hugo Junkers, and actually was in commercial service flying between Germany and South America before WW2. There was also a turbocharged version, the 207.
This engine had incredibly high efficiency, that usually means lower exhaust temperature and pressure= less noise. To be fair its hard to determine actual loudness from recordings due to multiple stages of audio post processing and how microphones work in general.

Because there is no heavy cylinder heads, you get a diesel engine light enough to fly aircraft with plenty of power. The Deltic locomotive has 2 Napier engines, weighs in at 100 tons approx with 3300 hp. From the same company (English Electric) came a loco with a V12 4 stroke turbo charged and intercooled. Similar weight but only 1750 hp. Both early 1960's vintage.
Ugh i love this advanced 2 stroke design, Drop this in a sled, truck or boat! Nothing beats a uniflow DFI 2 stroke! Rotax and Acahates power are getting it on with this tech.
Da sind alle Sicherheitsvorkehrungen auf dem höchsten Niveau! Die Kinder sind alle über 1,50 m weit weg und rennen nicht mehr rum, da kann man den Propeller schon mal frei rotieren lassen. Wenn einer zu nahe kommt dann bemerkt er es ja schnell, er wird einfach zu Gulasch zerhackt!
its ahead of its time Achates power is trying to get a moderns days OP 2 stroke into production , All this 2 stroke OP motor needs is a modern fuel and oil injection and there you go!
And she starts like every German engine first flick over and keeps better time than a Swiss watch. Be proud Germans, you earned it. Absolutely superb. Opposing cylinder two-stroke diesel- for aerial use. In 1920's. As RAF Captn. Eric "Winkle" Brown said, who flew nearly every German aircraft including Me262 and Me163: "They were at least a decade ahead of us". Team up with Indonesia- they're going to be economy #4 in 2050 with no silly revanchist territorial ambitions. It has everything it wants- it just needs to develop. Again- as Germany under THINKING leadership was there in the 1960s and 1970s. Forget China- it's too big for its boots, it's greedy and it rubs everyone in the region the wrong way. USA will cut them down for size and USA don't like competition. SE Asia will be a powerhouse.

I would say the reason this engine has survived so long is because of economic conditions in the Communist Bloc. When the wall fell, engines like this were still in use because there was nothing developed to replace them. I travelled all over the GDR from the fall of the wall and the second time I visited SKL engine works in Magdeburg there was a West German chap renting one the the buildings who was travelling around East Germany trying to save historic machines from the scrap merchants. As he said, he didn't always get there in time and missed some real rarities. He had two or three of the Junkers engines that had been powering gen-sets and pumps.

Wenn im Omnibus der Motor derart brüllt (durfte ich als Schulkind erleben), dass man sich im Bus innen drin selbst in einigen Metern Entfernung vom Motor nur durch lautes Schreien unterhalten kann, dann dürfte klar sein, dass ab irgendwann kein seriöser Busunternehmer so einen brüllenden Kundenvertreiber mehr am Betriebshof haben wollte...egal.Als kleiner Bub am Kaulberg in Bamberg, damals B 22, der Schwerverkehr ging mitten durch die Stadt, fand ich es schon faszienierend, wenn täglich mittags auf dem Schul-Heimweg der uralte Krupp Tiger (5-Zylinder Zweitakter) von Baustoffhandel Veit Dennert mit Vollgas im Kriechgang daherkam und sich reichlich überladen mit Tonnen Baumaterial und Dreiachser-Anhänger hinten dran unter Höllenlärm im Schritttempo den Berg heraufgekämpft hatte...der Fahrer hatte mir immer Drohgesten gemacht, wenn ich als Schulbub am Bürgersteig zu Fuss schneller war als er in seinem uralten LKW.Das war das tägliche Ritual auf dem Schulheimweg.

Uff. Was war ich doch fies und gemein als Kind...
I would hate to see this thing with expansion chambers like all the modern sleds have. Achates is trying to make a new OP 2 stroke with better emissions and efficiency. There is the new 850 ETEC rotax in skidoos. Are you running TCW3 2 stroke oil fed from the bottom?
The OPOC engine has unique bore to stroke and piston speed characteristics that make this design very desirable. The cylinder ports make sealing crankcase emissions a problem (smoky exhaust). I have a design for a 4 cycle OPOC engine, never seen one built, but I believe it would be more efficient than valve in head 4 stroke.
Why not, machine billet aluminum with a close clearace of the crank throws and the circumference of the crank and cut port ways up and run your favorite carbon fiber reeds, just time consuming. i got an 8v92 turbo silver i run 6 gallons of XD-100 BRP and some puled off and into the fuel inlet and i just keep adding it.

This was not the usual engine fitted to the Ju-52/3m. They were usually fitted with BMW-132 radials. The Jumo 205 was sometimes fitted to the Junkers Ju-86. The high altitude reconnaissance Ju-86P used 2 Jumo-207A engines, a development of the Ju-205. (www.warbirdsresourcegroup.org/LRG/ju86.html) The Napier company in England licensed the Jumo-205 before the war and around 1950 developed the Napier Deltic, essentially a triangular arrangement of 3 of these engines sharing 3 common crankshafts, intended for marine and locomotive applications.

NOw mae billet rods and pistons and a big bore kit with tuned pipes and turbo and you got and insane drag sled or drag car motor op 2 stroke.
Deny. Heavy Fuel Oil needs a Fuel System way too complex and heavy to fit on an Airplane. -HFO needs to be heated to about 35° C to be pumped at all. -HFO is full of Water, Dirt and all other Kinds of Shit, so it is pumped into a Settling Tank where it stays for 24 Hours before separating it with a Purifier.
Action the engine was designed in Whanganui New Zealand around 1928 to 1929 and the chap that designed it took it to Ford and GM And possibly more car manufacturers and as no one wanted the design he let the patent lapse and guess where it went..
Sorry, da bin ich anderer Meinung. In dem JU 52-Buch in meinem Bücherschrank sind Fotos drin von JU 52 mit JUMO 205 Motoren. Dass man diesen Motor in allerlei Flugzeugen ausprobiert hat, so auch JU 52 und JU 86 , weiss man doch, oder?
Stimmt, ich habe nachgesehen, es gab tatsächlich eine Version der JU52, die mit diesem Motor ausgestattet war. Sorry. Ich kannte die nur mit Sternmotor.
Wieviele? Das ist die Frage hier. Ju 52 ? Nur 2 Maschinen für Testzwecke. Ju 86 D-1 ? War in Serienfertigung. Blohm&Voss BV 138 ? Alle 297 gebaute Maschine waren mit Jumo205 bestückt. Dornier Do 18 ? 180 gebaut, davon 160 mit Jumo 205. Die Ju 52 als Musterbeispiel für die Benutzung dieses Aggregates zu nennen ist falsch.
Full expansion.... With today's metallurgy, we can use turbochargers to capture the energy that rushes out the exhaust port and heavy, expensive schemes like this are not necessary. That is why you don't see twin-crank engines today.
well you not total wrong the 5TDF,6TD and the Rolls-Royce K60 engine are built in the military with the today's technology the opposed-piston diesel engine have became more practical for commercial use. the engine desing are just too far ahead to its time really
according to bosch technical manuals this was a workhorse that was light years ahead when it came out. its not heavy its built like a brick shithouse because that is what made it reliable and expensive. there is a turbocharged version its the 207.

-HFO is full of Water, Dirt and all other Kinds of Shit, so it is pumped into a Settling Tank where it stays for 24 Hours before separating it with a Purifier.
the radiator must be huge to have a fan blade like that... no wonder he only let it run so long...
Fan blade? Its aircraft engine 😅
wow wow wow . super nice. these engines were used on the bv 138, amongst others..
German technology was far ahead of anything the allies had, just like this jumo diesel..
.
Action the engine was designed in Whanganui New Zealand around 1928 to 1929 and the chap that designed it took it to Ford and GM
And possibly more car manufacturers and as no one wanted the design he let the patent lapse and guess where it went..
I would install this in my international truck with bigger hood !
and shocks and axles
I had no idea there were any of these running!
Mal wieder der übliche Bullshit. Der Gegenkolbendiesel wurde in der Ju 86 eingesetzt und nicht in der Ju 52.
Sorry, da bin ich anderer Meinung. In dem JU 52-Buch in meinem Bücherschrank sind Fotos drin von JU 52 mit JUMO 205 Motoren. Dass man diesen Motor in allerlei Flugzeugen ausprobiert hat, so auch JU 52 und JU 86 , weiss man doch, oder?
Stimmt, ich habe nachgesehen, es gab tatsächlich eine Version der JU52, die mit diesem Motor ausgestattet war. Sorry. Ich kannte die nur mit Sternmotor.
Wieviele? Das ist die Frage hier. Ju 52 ? Nur 2 Maschinen für Testzwecke. Ju 86 D-1 ? War in Serienfertigung. Blohm&Voss BV 138 ? Alle 297 gebaute Maschine waren mit Jumo205 bestückt. Dornier Do 18 ? 180 gebaut, davon 160 mit Jumo 205.
Die Ju 52 als Musterbeispiel für die Benutzung dieses Aggregates zu nennen ist falsch.

Motor 2 tempos é muito melhor que de 4.
Motor DIESEL 2 tempos é muito melhor que de 4
Here's to you, Greta Thunberg !
StukAhhhhhhh
Imagine this 650hp Engine in a Panzer IV xD
Try 880+ HP
WITHOUT turbo.
furchteinflößend, besonders wenn man bedenkt das mit dem ding sogar 850 ps erreicht wurden.
Would be brilliant - for the 20 yards it took to reduce the transmission and final drive to shrapnel
@@rosiehawtrey of cause it dident fit without... minor.. changes ;)
More famous for being used on the Ju-86.
Sux no throttle
Full expansion....
With today's metallurgy, we can use turbochargers to capture the energy that rushes out the exhaust port and heavy, expensive schemes like this are not necessary. That is why you don't see twin-crank engines today.
Still, a 2-stroke diesel is a werry effective engine
well you not total wrong the 5TDF,6TD and the Rolls-Royce K60 engine are built in the military with the today's technology the opposed-piston diesel engine have became more practical for commercial use. the engine desing are just too far ahead to its time really
Equip one these with turbochargers and it will beat any 4 stroke in efficiency. They might still make a comeback.
according to bosch technical manuals this was a workhorse that was light years ahead when it came out. its not heavy its built like a brick shithouse because that is what made it reliable and expensive. there is a turbocharged version its the 207.
@asshat Jackson 2.7 liter....3 cylinders? Dude, whatever you are drinking, I want one!
