  3. The Volvo 5cyl had also an interesting history and lots of evolutions. At the end they where also in the Ford Focus performance models. Excellent video.

  4. This was made in the 90's, the thing is if it was as good as they say it is it would be in use today

  6. I love the idea. It makes good sense. This engine would last. Higher rpms are possible because of greater stability. I hope it's the engine of the future

  7. This is the best YT recommendation video ever! Very detailed animation. Subbed right away. Can you make Toyota 2JZGTE engine too?

  9. You had to back up steep hills.

  14. Hadn't heard hide nor hair of this engine before, but what an interesting take! Like Honda's oval piston design which was meant to mimic the advantages of a V-8 in a GP bike, Wirthwein's engine may not be an advance over the typical piston engine, but it's genius anyway. It also might lead someday to a practical and superior engine to what we have now. Interesting engineer and a well-done video.

  15. My first car was an NSU Prinz 4. I dismanteled it completly and rebuilt it overhauled, those days by a Hanes book (no internet or CD's). The timing was a riddle... quite exhausting and puzzeling. Also, I did resurface the engine head and haven't thought of the timing arms consequences.... it ran (maybe less optimal...)

  16. I've watched another video on this engine, but this, by far, was much more informative, You've gained another subscriber.

  18. Wow! Something I have never heard of or even thought of myself. I have thought about all kinds of things and then later see them invented and used somewhere so this is pretty neat. When I lived in Germany 1973 just outside of Spangdahlem AFB in a small village our landlord had a small farm and was a mechanic in another town. He had an NSU like in this video, I wonder if that was the same engine. Also interesting, he wore a suit and tie to work (nothing fancy) as a mechanic. I visited him at lunch time once and all the mechanics dressed the same, when they got to work they hung-up their jacket and put a blue or black long work coat on over their white shirt & tie. We ate in the break room, and it was amazing after washing hands they took off the long lab coat and hung them all neatly. I had a great time, they were so friendly and interesting to talk to we even all had one beer with our lunch. The whole shop was very organized and clean. One of the guys who worked there had a 64 SS Impala he bought from an American at the airbase.

  19. I like this old cars and motorbikes! I am repairing my motors myself-does'nt matter,that they are 90 years old

  20. It's a good little car/truck, and you can have it in any color you like so long as it's black.

  21. You forgot 2 stroke outboard engines for boats (up to and including V-8 engines) and inboard Jet Ski watercraft's. as well as snowmobile and ultra-light aircraft engines. you also did not mention just how many 2 stroke die hard fans there are around the globe. NOTHING can compare to the lightweight horsepower that can be achieved with a highly tuned 2 stroke. and the really odd thing about those highly tuned 2 strokes, is they can also be quite fuel efficient at the same time. Also, those "heavy" rotary valves and reed valve parts that you are describing, weigh in at less than 8 ounces typically if properly designed. the "loop charged" deflector pistons were ridiculous though. they were a very poor design. and limited R.P.M. SIGNIFICANTLY.

  22. This is the best video I’ve seen in a while. That boxer engine looks spectacular.

  23. Great video. Straight to the point.

  27. Worked for G.T.E wesgo Corp in the 90s. We worked on a prototype ceramic 4cyl engine. Extremely impressive #'s, super lightweight, on cmm machine was No wear....engine would theoretically last forever(well, owners lifetime) it was cast into a block of cement and dumped at sea. No $ in a engine that won't wear out.

  28. WOOOW this engine is an actual wonder in all engine designs, if this get on actual car or motorbike this gotta be a big game changer, considering its supposed wonders

  29. Back in high school I bought a 1958 VW bus with a sliding hardtop for 50 bucks from a friend of mine. It kept popping out the exhaust and bad misfire. Took the engine out and took it to my auto shop and we all split the case and tore it apart and never got it fixed. Now I know I could have snapped those heads off in 20 minutes and put new heads on it. I'm very disappointed in my auto shop teacher but he's probably been dead for 30 years, lol.

  30. There's cylinder ring friction, but granted less

  31. Thank you for such a detailed and GREAT video !

  32. Thanks! I had a '68 Bug in high school back in 1984. Loved its simplicity.

  33. The best thing about the model T was that unionized workers in that age could afford to buy one. It was a terrible car, but, as someone else pointed out, better than a horse. My grandmother's father owned one and drove it around Florence, Colorado. They had to fix flat tires regularly, and as someone has said, back up steep hills because of the gravity feed fuel system. If the engine backfired while you were cranking it, it would snap your arm, a common injury in that time. Yes, it was well engineered for its day, but a model T cannot handle modern traffic. It does not have enough power or good enough brakes to drive on a freeway. It pollutes like crazy. In a crash this car would come apart, and with no seatbelts you would lose your teeth or worse on the steering wheel. I would not want a family member driving one. These belong in museums. I've been driving and fixing cars for nearly 50 years and here's what I know: The cars of today are the best in history. Comfortable, reliable, powerful, energy efficient, and safe. Virtually zero maintenance for 150000 miles and many many times safer than a model T or even a car from the 70's. And the electric cars that are arriving now are better yet, wayyyy better. Soon self driving cars will take disabled and older folks safely and conveniently where they need to go. I have several family members who cannot drive so this will be a new time of freedom for them. The model T made car ownership possible for the masses, a wonderful freedom. But let's not get too nostalgic. My next car will run on sunlight and drive itself when I'm too busy or bored to do it. It will be safe, quiet, fast and efficient. I'm looking forward to the future.

  34. Subscribed simply because you didn't put your face in closeup for minutes on screen but instead opted to stay in the margins and using loads of animations as content. I hate the "big face on a big screen staring at me" style that many channels use.

  35. You're 3d representations are amazing

  36. Glad you mentioned the DKW

  37. Thanks for the great video. I really appreciate that you explain the benefits and design philosophies behind the engines various features. That makes it great for the folks that folks that don't know much about cars, and but are a little bit curious about everything.

  38. Thanks for the video. Hoping to see this channel grow more!

  39. Very cool design! I love the V8 sound at the beginning. Let's build a hot rod Taurozzi!!

  40. Number 3 cylinder often had problems because airflow was affected by the oil cooler placement. During a rebuild I would often see cracks in the cylinder head between the spark plug opening and the valve ports.....

  42. Unfortunatly simplicity in today's world just isn't practical. If its complicated, that's today's world. I would DARE someone to come up with something simple. I'm convinced that MOST people would go for the more simple things in life, but most manufactures DON'T KNOW HOW to do simple!!

  43. Its a good idea but no doubt you lose some efficiency driving the super charger (which is more than pumping losses of a conventional 2 stroke). Of course having a smaller capacity engine should help with fuel efficiency so will be interesting to see what fuel efficiency ends up like. As far "Do I think it will delay the arrival of electric cars ?", I think the answer is not significantly as I think that the horse has already bolted (in a lot of countries EV sales already outweigh ICE sales), but maybe it will help Mazda hang in there.

  46. Seems like a very smooth 4 cylinder.

  47. i give it a year before a youtuber releases a video "I built this Taurozzi engine and you won't believe how it works! "

  48. In the 1980's as a young man you would see them boast in magazines about new technology like turbo's and double overhead cams, to name two. Then I found a book from 1920 and every thing they boasted about already existed. That's the power of false advertising.

  49. Great work as always

  50. I had a 69 beetle back in the early 1980s. I was pretty abusive to it as a teenager and finally it dropped a valve. It was a good car. Maybe one day, I will own another one, but I will be gentle this time.
