  4. car companies make more money if things wear out and need to be replaced more often. Engineered obsolescence. Think about it like medicine. the money is in the treatment, not the cure.

  5. Bro! The way you explained everything was on point. This is the kind of work I like to see. I'm subscribing

  6. A better translation for „Kübelwagen“ may be „bucket vehicle“.

  7. I used to have a belgium made FN 175cc two stroke with two pistons behind each other. It has only one spark and combustion chamber. The special thing on this type is that there is a main piston rod and the second is not fixed at the bottem of the first. It is made like the connecting rods of a star engine with hinges.

  11. Nope . Sorry ,its not going to be built as a mc or car engine. Maybe if it had 1 hp per cylinder ,to many joints and moving parts compared to a normal engine. Maybe in garden engines . But the 125cc sounded really good , i would guess a much bigger engine. Sorry about my english ,from Finland!

  12. More of a hemi than the american muscles now tbh😂

  13. How much is the engine by itself worth? My guess would be around 200k.

  14. more bang per revs mean an inline four could sound like a v8

  15. Wait wait wait. There’s bigger than 1600. I’ve got a 1776cc and I know they go up to like 2136cc or near that

  16. Hi, I really love this channel, I have a recommendation. Could you make a video on Porsche's flat 6 engine? Or Subie's boxer engine?

  17. Nice video!!

  18. A very well done video. However, I have to disagree with you on one thing and that is the camshaft drive. The large gear was made of some kind of compsite material that did not last very long. In my young mechanic years I replaced dozens of them. Later they changed to aluminium and that solved the problem. They also had a problem with the cooling of #3 cylinder for many years

  19. Too much complexity. No benefit. Might as well just have 1 gear driven camshaft and pushrods. The possibility of valve float can still exist since there is a overhead cam. Interesting although. Great video

  20. Hi, Repairman22, Thanks for your discussion on the split piston ICE. The main idea for it is the huge differences between the gas pumping exhaust and intake strokes and the heavy compression and power strokes for the ICEs. If we split these two functions the engine can run at 1/2 of the rpm for the same work otherwise it will produce 2x (actually 2.5 to 3 times torque). So the crawn section can be redesigned to run at somewhat higher speed with lighter system, since it just pump gases around. Basically, this design make an different hybrid of different kind. Other issues such as: 1. windows in the skirt is not away needed or just a litter cut is enough. 2. the cooling is much easier when stronger and thinner crown is used. 3.there is no oil leak issue if the piston rings are OK, 5. the "extra moving parts basically is the extra cylinder, i.e. i4 becomes v8 (or 2.5 to 3 time output), 6. The engines would run at half rpm, not the 1000rpm, 11. the push-down spring has the help by the the cylinder press at high rpm when the engine is loaded. The crown (piston-train) has about just a little high speed or the same depending upon what differential strokes are designed. The crown section is only to pump the gases around, which much, much lighter than the pushing the whole vehicle around.

  23. Absolutely love the video, what a masterpiece this engine is, thank you.

  24. As you mentioned that 5 stroke benefits only higher engine loads, forget cars and motorcycles and add marine and aircraft engines to generators and range extenders. The need for those continuously high load engines are million units a year. This innovation really has markets.

  25. Omg just discovered your channel, it's so good quality. Thanks for the sharing of knowledge and making the research job that easy

  26. My first car was a 56 vw in 1966 I paid $100 for. You could remove one cylinder, piston and connecting rod without removing and disassembly of the engine. It had a sunroof and by pulling out the choke a bit you could drive it standing on the seat and halfway out the top. (College days). You can't beat it in the winter in deep snow with chains and being flat underneath you slid over deep snow drifts. The heater didnt wok so I tore all the guts out of the heater boxes and closed the little doors with sticks in the fall and all the air that cooled the motor was blown into the car. I had to drive with my windows down on a trip. If you got stuck you could speed up the engine a bit with the choke and get out and push with it in first gear. Driving through the Rocky Mountains in British Columbia was like rowing a boat with all the shifting. I cut 2/3 off the shifter to make it easier. I loved that car.

  27. The engine was also used as a pump for fire fighters.

  28. This looks like hell for maintenance. Looks designed for engineers, not mechanics. Probably a good step in looking for that next big innovation, but i dont think this is that innovation

  29. A cousin of mine stayed in India for years, living off nothing else but repairing 2CV there. In Germany we call this car "Ente" (Duck), thus his motto was "Ich schraub nur Ente" (I only do Ducks).

  32. After going to the so-called 'manufacturer's' website... it appears to be an engine that can sorta run for 8 seconds. I see a failed kickstarter coming. And it only runs on hydrogen. There is no possible way something like this can run on a conventional fuel and be useful in any application. I would expect it to produce close to zero torque. I appreciate your animations... but it is unlikely to go beyond that.

  33. Super video. Well made . Thank you

  34. A whole lot of people in this comment section couldn't even watch an 8 minute video in it’s entirety before posting their comments, pointing out that detroit diesels exist doesn't make you seem smart, it only shows you didn't pay attention to the video

  35. Bali island. You can tour the island by renting a VW beetle with open top + driver/guide. Better view when there's no roof. There's an unwritten law, that VW owner can't sell his car outside Bali.

  37. I can remember that this engine is nearly indestructible. Both my mom and my dad had a 2CV and they made road trips all around europe and when the car was done from rust, the engine lived on and as far as i know, it runs to this day.

  39. It’s an interesting engine, but like lots of French engines and cars , seems to lack any consideration when it comes to maintenance or repair. It’s like they though ‘how can this be made as hard maintain as possible?’ The points for the ignition timing are behind the flywheel. Completely inaccessible. Good location? Not. I hate French cars, everything seems to be designed to be in the worst possible place, nuts and bolts go in backwards, and hit the chassis, but if they went in the other way they would come out easily. It’s not accidental, it is deliberate. They want to make the repair times as long as possible, so they can charge 5 hours for a job that could be done in 1 if they just used bolts instead of studs, or studs instead of bolts, etc.

  41.  @repairman22  This is a program for professionals, I am an apprentice, following your suggestion I found a nice image, I will try, it will be an interesting challenge, your channel is incredible.

  42. all that engineering for incredible 9 hp

  43. It looks cool and very interesting, but I don't see why it would be fundamentally more efficient than a standard engine.

  44. Very informative. But I gotta be that guy.... his name was pronounced, Porsche (Poor Shuh)

  46. ​ @repairman22 glad to hear there are still real people narrating, the amount of videos with no human voice are quite worrying from the point of view that we, as people, should still be willing and able, more capable of making a good, well read, pertinently expressed narration, with touches and nuances that AI has yet to accomplish. I think, w.r.t. the 4 stroke comment, I was, as some people might, considering each of the 4 stages of the cycle as a crankshaft revolution, rather than happening in a downstroke or upstroke of the piston. Thanks so much for pointing that out! I have watched several of your other videos too, like Ford Model T, VW Beetle engine, 2CV engine, Titanic, I think it was, a fire engine truck, et al, and your work is a joy to consider, and helps one understand so much more than was once possible when I was a youngster, and graphics were mostly static pictures, with slight descriptions. Best wishes!

  48. 4 strokes = stronger power strokes 2 strokes = more power strokes.

  50. The rings dont rotate, the inner combustion cylinder does, spark plug is affixed to outer stationery cylinder and protrudes into central axis port seal.
