DKW Drive and Two Stroke History

[@vitorcamilo6796]

Congratulations from a Brazilian DKW owner. That`s a fantastic history ! Thank You.

[@matthiasmaiwald8236]

Very nicely made and informative video! Brings back fond memories. A DKW 1000 S was our first family car when I was a little child in the 1960s.

Hi Paul This was my first car back in year 1963 when I was 21my first driving test super car to drive, 90,000 before engine packed up. nice to see it again Reg 7dmk ex racing driver before I had it. regards Mike from Yeovil Somerset UK.

Great video. Very interesting history. Love two-stroke engines. Enjoy that very particular automobile.

[@faizalvanderschyff6699]

I had one of these 1957 DKW cars. This brings back memories, especially that unique exhaust note

[@paulmarkham3187]

They are a great car. I love them

[@mrtelechi]

Can't believe just how interesting, and how much I enjoyed this. Thank you.

[@johnjlohan5628]

Enjoyed that. Nice to know of Audi's past. Very well explained.

[@fabiogn1]

Thank you for sharing your knowledge on the 2 stroke engine and DKW . Congrats from Brazil.

[@thelovertunisia]

The car is in an amazing shape.

The two really big game changers for 2 strokes were: (1) When Jawa invented transverse porting in secret, under the noses of the occupying Nazis, in 1944. Producing the world's first transverse ported 2 stroke motorcycle (the Jawa 250-10 Perak) in 1946. The Jawa 250-10 Perak has a top speed of 80 MPH, which was at least 30 MPH faster than previous 250cc 2 stroke motorcycles. This transverse ported 2 stroke engine design is what became widespread globally, not the Schnurle single opposed port design. Schnurle's design was to angle the port's entry to the cylinder upwards, thus eliminating the requirement for a deflector piston. All previous 2 strokes had the port aimed directly horizontal. In a transverse ported 2 stroke cylinder, the ports are of the Schnurle type, but set at 90 degrees to the exhaust port to create a swirling action during scavenging. (2) When Walter Kaaden, of MZ motorcycles, invented the expansion chamber exhaust system.

Fascinatingly informative, both from the historical and the technical points of view. From hearing and seeing your driving, it seems that your little 850cc 3-cylinder engine runs as sprightly and smoothly as a 1.7L 6-cylinder (hence 3=6 and 850=1700 !). Spending my childhood in Brazil in the 1960s, I well remember the Brazilian-made DKW Belcar 4-door saloon - mainstay of São Paulo's taxis, and the Vemaguet 3-door estate car, with their whine and pop engine sounds. I was of course far too small to drive one, thought I would have loved to do so. It seems that the DKW even got to Australia with right-hand drive!

[@paulmarkham3187]

Hi Yonathan. Yes a very few of these cars made it Australia. About a twenty maybe? They weren't popular sellers after the war. Before the war they were though next they were tough and low maintenance. My car came from South Africa, where there is a strong enthusiast community. I have heard Belcars running and they do sound different. I think it's due to the exhaust system they use. DKW were very particular about exhaust tuning. I have tried three different exhausts on my car but the original is best, better power and less noise.

[@creepycrawlything]

Enjoyed the video, the history lesson, sight of the car, and the cityscape. Video watched near Perth, Scotland.

[@paulmarkham3187]

Glad you enjoyed it

[@bluemoondiadochi]

Excllent video! I had no idea that's what it took to make the two stroke engine the engine we know and love today. oh and i wouldnt call it rambling, you could have just rambled and let the camera roll and uploaded that, but i appreciate that you took the time editing in the photos, which take the vid to another level. Much appreciated. Maybe you could have talked a bit more on DKW cars proper, but then again, i havent checked your other vids so can be you already go that covered. And the DKW f89 is one BEAUTIFUL machine! Would drive a (preferably black or biege) one any day over a modern car, just looks, sounds fantastic.

[@paulmarkham3187]

Thanks. I will do another video soon. I haven't done one for a long time.

[@alanlewis1766]

I have got a 1962 universal sitting dismantled in the shed need to put it back together as I learned to be a mechanic on these cars in 1966 at a dealer in ABERYSTWYTH WALES a very educational location to work at.

[@grisa29]

Nice, thanks from Slovakia!

[@gravelydon7072]

Looking at your interior matched the one we had. Except for one thing. Ours had a windshield attached spotlight just above the mirror. Same colors though. When you are mentioning the engines, I didn't hear anything about the supercharged 3. Well actually it wasn't a 3, it was two 3s. The one side acted as a compressor while the other acted as a regular engine. Solved the fuel/air mix mixing with the waste gasses by forcing it out of the engine.

[@patrickcannell2258]

You love 2 strokes. If you're a biker, Suzuki GT750 water cooled 2stroke triple. Mid 70s.

[@Isayso1]

Hi. Nice and informative video. I would Like to state, that imho your engine ist running a little on the lean side. I suppose a readjustment of the needle hight might help out. Schnürle had sold the idea of the "Umkehrspülung" to Mannesmann and as they were in Diesel engines only, they gave the license for Petrol engines to DKW. I think it was 3,50 Mark for each engine build.

[@jurivlk5433]

My father had the East German brother, the IFA F9. But it had less power than the DKW and had problems on grades!

[@paulmarkham3187]

I love the IFA F9. There is evidence that at least one was registered in NSW, Australia.

[@paulmarkham3187]

The DKW also struggles with gradients. It gets slower and slower until you are crawling in first gear. Good for the Autobahn. Not for the mountains

[@jurivlk5433]

@@paulmarkham3187 I'm astonished that you know that car! Actually, we flew from the Russian invasion with it and it was fully loaded when we had to climb a mountain pass in Austria. I vaguely remember to walk with my mother alongside the IFA when we crossed that mountain! I think the IFA had under 30 HP so imagine that car loaded with people and stuff! But it was a big upgrade to the former car of my father, a Aero 500! That one you probably won't know! 500 cc engine, also 2-stroke, from 1931 or so, two seats plus mother-in -law seat in the back and: No differential at all!!! But they got far with it, up to the south of Africa! (Not my father but an expedition in the 30's). Your car really looks great! Congratulations. And Australia is flat! But how does it cope with hot wreather with only the thermosyphon cooling?

[@paulmarkham3187]

Oh yes, I know the Aero 500. From Czechoslovakia. It was a bit like the Jawa 700 (which was a copy of the DKW F2) but smaller. They were independently designed but very similar. There is one I know of in Australia which was up for sale a few years ago. I would like the later model with the streamlined front and long bonnet. They look very nice.

[@jurivlk5433]

@@paulmarkham3187 Not very common that someone knows the Aero 500! But the company, which mainly still build small planes, is quite known among aviators. The Aero 500 was a very small car, like a BMW Dixie or an Opel Laubfrosch, if you know them, but Aero also made bigger, quite good looking cars with small engines. They really look art-deco or ",american modern" as that style is called more precisely.

[@zundapp8229]

Hello Paul, just came across you, on KZbin, as you do!! Most interesting. You obviously know your subject!! I have owned many many German cars, but all since the late 80,s In the 60,s I ran a Zundapp scooter which was a German 200cc two stroke.it was most reliable,as most German stuff usually is. Best Wishes Roy W, Nantwich UK

[@paulmarkham3187]

Zundapp Bella? They are a magnificent machine.

[@zundapp8229]

Yes, it was a Zundapp Bella model R204. I ran it to 60,000 miles and then part exchanged it for a Austin Minivan. Apart from de carbonising the engine, it never required any attention at all. The Bing carburettor did however have a tendency to ice up in cold weather, which gave a few exciting times.

[@graymodeler]

I had a model airplane with a Schneurle ported 2 stroke. It cost more but had more rpms and power than a regular K&B 40.

[@davidpicard9368]

I rode a dkw power cycle in the fiftieths. Any pics would be appreciated!

[@paulmarkham3187]

Do you mean the DKW Hummel moped? I have one of those dkwautounionproject.blogspot.com/2022/02/my-1956-dkw-hummel.html

[@Frightningman]

I'm surprised that you never mentioned the DKW split singles which they were so famous for.

[@paulmarkham3187]

Yes they had split singles in motorcycle racing but I can't talk about every engine they built in 20 minutes

[@Frightningman]

@@paulmarkham3187 Yes but they used the split single on road bikes too. You appear to imply that DKW invented the two stroke, but it was actually invented by Joseph Day, with help from Frederick William Caswell Cock.

[@paulmarkham3187]

No, I do not imply DKW invented the two stroke. They implemented the Schneurle reverse scavenging method, which is the basis of the modern two stroke engine, improving the engine's efficiency.

[@bersyukurvlogs420]

Very nice vedioy friend 👍👍

[@christiankastorf4836]

Hilfsmotor should be understood as auxiliary engine.

[@geraldwagner8739]

Very high revs. The engine almost sounds like a turbine.

[@Howster69]

Is the exhaust noisy on these cars?

[@paulmarkham3187]

Is it?

[@mr.145]

Would anyone know if these cars did high mileages ? i.e 50,000 plus,ive got a Mz 251 2 stroke motorcycle and these can do high mileages.

[@paulmarkham3187]

They definitely could and did do high mileages. Mine had 74000 miles on the clock when I bought it. I have on my DKW blog a lot of period magazines which have write ups about some prewar cars doing 500,000 miles or more. There was also correspondence between the British DKW club and Auto Union about servicing the crankshaft. The British owners were used to English built cars that needed an engine rebuild every 10,000 miles so were always pulling their engines apart and replacing the German bearings with British ones, which would then fail in 5000 miles. The club wrote to Auto Union about this, who replied that they should STOP as the crankshaft was good for 500,000 miles without servicing at least. Today DKW owners regularly drive their cars on long trips without any problems. Mine loves the freeway!

[@mr.145]

@@paulmarkham3187 Thanks for the interesting reply,im sure the newer synthetic 2 stroke oils,burn cleaner too.Which would help their longevity too👍

[@paulmarkham3187]

Yes, the new synthetic oils burn cleaner and you don't quite need as high a ratio

[@Schlipperschlopper]

Sadly from 2030 on all the combustion cars including classics will be banned from public streets in EU :-( In Germany the Green party gave order to shorten fuel supply from 2025 on by reducing petrol stations to only one station per city. :-(

[@paulmarkham3187]

This isn't just happening in Germany. There are discrete changes being made all around the world to slowly remove our rights to use old vehicles - even normal petrol vehicles. There is constant pressure on the government from lobby groups to reduce road speed, limit vehicle use (especially old cars) in the name of 'road safety'

[@paulmarkham3187]

And all this 'global warming / crisis' is bunkum. There is no crisis. Pollution has been reduced year on year over the course of the last 50 years. Global temperatures have been declining year on year over the last century. The global warming fraud is being perpetrated on us all to rob us of our rights.
