  2. My grandpa bought a VW BEETLE brand new in February of 1959. He drove it every day until he had a stroke in 1984 and could not shift gears anymore. He gave the beetle to my dad and he kept until 1998. At that point dad the beetle to me and I still have it to this day. We estimate that the little beetle has had at least 5 engines. 3 transmissions. A dozen or so clutches. Hundreds of tires. I drive it when the weather is nice. Sometimes I look at it and I'm totally amazed. I can remember Grampa dropping me off at kindergarten in that little car, now I drop my grandkids off in it. Maybe one of them will have it someday. Oh I forgot to mention that we're pretty sure that it has well over a million miles on it.

  3. Of course a car made 120yrs ago appears primitive by modern standards, but if the alternative was having to ride a horse I'm sure even a modern motorist would be grateful!

  5. Wow, that poor guy. What an innovative smart dude. It’s a shame he got hurt and disabled, but it is certainly admirable that he still made those motors and got them running!

  6. Gear driven camshafts. The ultimate in reliability and peformance. No timing belts/chains to break.

  7. They paid me one summer about 50 years back to drive a few of these around Greenfield Village, where they had a small fleet of them when some of the newer models were only about 50 years old. Brakes were always terrible.

  8. Your graphics, timing, rhythm, relative volumes, etc. make this a pleasure to watch. Anyone can read a script, not anyone can do it in a way that makes the viewer never once glance to see how much longer is left or be tempted to fast forward. Thanks.

  10. Normally a piston completes an up-down movement in 360 degrees. With this setup the top of the piston has an additional up-down movement in approx 60 degrees. So with the engine running at just above idle at 1000rpm this piston top will be moving back and forth as quickly as if it were 6000rpm on a conventional engine. It won't be able to rev up without enormous forces and consequent breakages to contend with.

  11. Horses at the time were also a viable option. They contained more moving parts but maintained themselves through biological repair processes. The horse ran on hay and grass which was plentiful and free. The exhaust, in the form of smelly clumps of droppings, were non-polluting and could actually be sold for use as fertilizer. A horse had approximately 1 horse power and four hooves which provided locomotion in lieu of wheels. Horses were manufactured by other horses, sometime several at a time, though it took at least two horses to make them. The downside of horses to automobiles was that horses needed to be kept on (alive) at all times, they needed to eat and drink even when not in use. They would also sometimes die and there was no way to bring them back to life no matter how much people paid the local horse mechanic. If a horse's hoof went bad it couldn't be removed and replaced with a new hoof, cars on the other hand could have their tires replaced if one became damaged or deflated.

  12. I've had a -59 B425 and a -79 2CV6, 605cc. Both absolutely lovely everyday cars. On twisty gravel roads I could keep many times more powerful cars behind me. The body roll wasn't a problem and all 4 wheels stayed on the ground at all times. The time I lost on the 'straights' I easily gained through the tight bends. Very annoying to some... They never broke down and I used them as my every day cars, all year round...even below -25C°, completely closed air intake and plastic foam sheets in the roof lined with corduroy fabric. There are so many clever solutions incorporated in this technically advanced car, that even formula one tech people know of them and refer to the 2CV regarding certain aspects. The whole story would take to long to tell here. Thank you for bringing the 2CV back into the limelight where it belongs!

  13. I actually own two Taurozzi breathing air compressors. They’re pretty neat.

  15. I've lost count of how many of these game changing engines are supposed to have been on the market by now.

  16. The T engine was bolted into the Chassis. The spark plugs were fired by flat uninsulated brass conductors, that were bent and so held themselves in place. The lack of fuel pump required it to reverse up hill. That reduced road grip. Drivers always needed water for the engine. The wooden spokes, in artillery wheels, might Take a long soak to swell and tighten up.

  17. This looked like an engine with some serious potential, too bad it wasn't developed further. AND I LOVE YOUR ANIMATED ILLUSTRATION!!!!!! We need more productions like this!

  19. What a guy! While a simpler design is always preferable, nothing can beat the elegance and ingenuity of an overcomplicated mechanical solution. Even if it's not actually better, it's still a win for the fact he did this all himself. It's not a question of 'why' but rather 'why not'.

  20. I am sure this is being done due to size constraints to operate as an apu range extender on EV cars. Operating at a constant speed would eliminate many issues inherent to this design in a conventional application

  21. I remember being at a motorshow a few years back when the W12 was introduced. The guy on the stand explained in depth how it all worked and it was absolutely fascinating. Had a full scale cutaway model too. The W16 is like that on steroids. Tremendous piece of engineering

  22. Wet belt is the worst thing corporate did to engines.
    230
  23. The rod system sounds quite interesting and I never heard of it. That explains why the little NSUs are still racing until this day. The wetbelt system on the other hand is such an engineering disgrace that it is not worthwhile mentioning!

  24. My dad won a 2CV back in 1954 in a contest with Gulf Oil. His jingle was, "fill up with Gulf and you will see, no tailpipe smog or exhaust debris". The theme was emissions. I may have never been if not for that car; he sold it, and used the money to marry mom and honeymoon in Niagara Falls!

  25. The Ford Ts flathead is about the only thing that remains an astoundingly reliable mechanism. It’s true that the side valve arrangement makes an engine immune to valve drop and eliminates damage potential from extreme valve timing issues. Valve drop, by the 70s, was a virtually unheard of issue, but it can happen in OHV engines. The benefit of the flathead, though, is that you can use dirt cheap materials and not worry about it. The multiple-spark system (called SOS in airplanes) helped with the bad gas available at the time, and improved starting with low-grade fuel. It certainly helped with starting especially, but with modern fuel is entirely unnecessary. The T used a planetary transmission, which reduced its likeliness to strip gears, and it’s certainly less likely than even the most modern manual transmissions to strip out and have serious damage. But it was controlled by tightening cotton bands around the ring gears, and these go bad almost constantly. If it weren’t for the cotton bands, the transmission would have remarkable reliability even today. But because of the cotton bands and how they behave, the reliability is very low. The fuel system is drastically improved by the addition of a fuel filter. The bladder device used on the T was sub-par even for its time, and it said in the Ts manual to filter the gas before it was even put in the car. The oil slingers (called “spoons” here) were so woefully inadequate that the addition of an oil pump more than doubled the lifespan of the engine - when oil pumps were introduced they were seen as being the saving grace to reliability. People who lived in mountain states used to fill them so full of oil that they would smoke as if they had blown rings, so much so that bystanders would think that the car was on fire, and this would wind up doing damage all on its own. In some places people associated oil pumps with clean air. The carburetor was finicky and didn’t have an air filter. If dust gets in it’s like grabbing sandpaper for rings. And in many places there’s dust, including on earth. Finagling the carburetor to turn on the car made the car difficult to start. I’ve had experience with crank-start engines that have finicky carbs and they’re an absolute nightmare to get running. The introduction of electric start seems to us as a footnote in history but to the people at the time it might as well have been a gift from god himself. There is the problem of having to back up hills because of the gravity tank, but that’s not a reliability issue it’s just inconvenient. The lack of a water pump is a nice little niche, but that’s because of the low power of the engine vs. its surface area and size. Anything even slightly more substantial needs a water pump. It’s cool that it doesn’t need one, for sure, but no modern engine can do without it, besides something that’s air-cooled. If the Ts engine were designed today (in fact, any engine in any riding lawnmower has made the same HP since the 80s) it wouldn’t have water at all, it would have no water plumbing nor radiator and would just be air cooled. The cooling system on the T is actually quite a lot more complicated than any equivalent engine designed today.

  26. Some VW factory engineers who visited the USA were absolutely amazed how VW mania had added so many performance upgrades to the engine , to the body and to the handling this was expressed in an Automotive Magazine in Germany and inspired a lot of respect towards American VW aficionados

  27. I had a 1926 Ford Model T Coupe in the late 1980's. Yes, the splash lubrication is simpler, but there is a problem. The T was designed in Michigan where it is fairly flat, but I live in San Diego California. I was driving up a long hill with my T, and burned up the rod bearing on the #1 piston. It was not getting enough oil because the oil was mostly in the transmission and back of the engine due to the incline of the hill. In the Model T club, people add an extra quart of oil if they have to go uphill. The brake band in the transmission was just not enough for going down steep hills. In '26 the brake band was made wider to try to help the situation. Due to this, companies made what were called "Rocky Mountain Brakes" that were attached to the rear wheels. An air filter for the carburetor should have been supplied from the factory. In all, I enjoyed driving the car to special events or on special occasions.

  28. I remember a video where a guy sent a DB601 crankshaft into RR to have it measured and checked. The engineer at RR said the specs were spot on to its very high tolerances He said don't drop it because they couldn't make another like it the tolerances were so exact with their modern equipment. Imagine they were doing this in the thousands under constant bombing of their factories.😮

  29. My grandfather told me if a hill was too steep, he'd have to go in reverse up the hill but I forgot why as I was very young when he shared the stry. Now I remember, graviyy fed fuel! If he didn't go in reverse up the hill, putting the tank above the engine, it would stall for lack of fuel to the carb. Thank you for bringing back a memory of my granfdfather.

  30. I had never seen a twin single engine explained before. Nice.

  31. Ground breaking stuff. Mazda is one of the few manufacturers that pioneer new engines.

  32. It would seem easier to me to make the changes at the head end rather than the end that it moving all the time. A 10cc "bolt" that can be screwed into and out of the cylinder is about all the difference required to vary a 6 cyl 3000cc engine from 11:1 compression to 9:1.

  33. The T was made in an era when there was little if any mechanical distinction between cars and farm equipment. It had problems of course, but it's amazing that it was able to run relatively well using such primitive means of lubrication and cooling.

  34. Crazy how ahead of the times the skylines were, all in the times before CAD. This is a good video and needs more views.

  35. I'm impressed. This engine epitomizes elegant design.
    87
  36. I liked the crankcase case compression ratio explanation never thought of that!
    85
  37. Huge thumbs up to them building a working prototype and making a video of the engine running! That already sets them apart from 99% of the other "innovative" engine designs.
    81
  38. Fantastic explanation! Very inspirational to copy the good attributes of this engine. Now I must ask, could you do a engine comparison between 2 somewhat unknown engines? I've never seen them compared even though they perform so similarly while functioning completely differently. Fiat 126p & Trabant 601. You don't have to, obviously :)

  39. The vacuum advance system actually advances the ignition when cruising and the throttle position is nearly closed. The high vacuum in the inlet manifold pulls the diaphragm and advances the ignition as the mixture has leaned out at this throttle position (lean mixture has a slightly longer burn time).
    67
  40. Steam locomotives also used these types of rods, they seemed that they existed for a very long time ago.

  41. I think for a compromise between cost and longevity, the chain would be the choice. I am not an engineer, just just an old guy who has been messing with cars for the last 70 years. Everybody will have a good reason for their choice, though, I am sure.

  42. I've watched four videos on this engine and this is the first one that had any explanation of how it worked, the pros and possible challenges in making it work. I'm definitely subscribing!
    61
  43. I’ve seen a lot of engines from radial to rotary never have I seen something like this 👍
    56
  44. Yes WOBentley used this configuration in the 1930’s on the 8 litre Bentley. Ran like a watch and it came from his apprenticeship experience as a steam engine engineer on the railways.

  47. I loved this, and was wondering how they compared to today's cars. Thank you so much for posting.

  48. Thing was and is still pretty brilliant! I wonder with newer technology if this was redesigned with the same basic ideals what it would look like and how it would do. I wonder if it could be sold. Nice video and visualizations!

  49. You did a really great video on the VW air cooled motor but there are so many modern modifications that companies are doing that have improved this little motor . I have a 1979 convertible that’s a 2180 cc putting out around 150 hp and I’m building a supercharged one for another car I’m working on .

  50. Non-stop information, and great visuals and 3d animations. Awesome video, hope to see more like this - thanks!
