Hearted Youtube comments on Repairman22 (@repairman22) channel.

  1. Yes 2 stroke engines burn oil but our brand new cars burn a whole lot of oil
    46
  2. There was also no oil filter and the bearings were poured babbit. This engine had more in common with briggs and Stratton lawnmower engines

  5. Bevel gear drives were very common before and during WW2 but by the end of the war, pushrods had been made light enough to be competitive even for light racing use. As you rightly say, the eccentric drive does depend on consistent centre distance, however it can be improved by moving the driving gear off to one side and allowing for a little up and down movement in the bottom anchorage for the distance piece. Bentley used an eccentric drive with three eccentrics at 120 degrees which is just about the ideal but expensive. However, the bearings of the rods do wear and are much more expensive than replacing a chain or belt. Steam engine eccentric drives had means to adjust the centres of the straps on larger engines, quite impracticable for the enclosed straps and bearings on a car or bike engine.

  6. Amazing, been driving for 50 years, love cars, lived in the town where Bubble cars were made, but never even heard of this engine type. Thank you I enjoyed every minute.

  7. Waking up to this was an unexpected surprise. I never heard of a hydraulic supercharger and it's counterintuitive to me that higher compression ratios are better for fuel economy. Very interesting and informative. This is my first comprehensive look at the Messerschmitt BF 109 engine after learning about it decades ago.

  8. Just a detail Having worked on 2 stroke diesels both opposed piston and valved the exhaust valves open before the piston uncovers the inlet ports so as to allow the residual pressure in the cylinder to blow down and the valves are shut before the piston has recovered the ports Great vid

  9. Well done. The cooling issues were covered well, didn't know about them until this.

  10. Stellar work! You got a perfect eye for what details to focus on and include while still getting a good & quick flow in the video 😃
    33
  11. Excellent video. The discussion of pro- and con- adds so much to the visuals 😃 Really sets your hard work apart from other creators

  12. In 1906, the Land Speed Record was broken by a Stanley steam car, piloted by Fred Marriott, which achieved 127 mph (204 km/h) at Ormond Beach, Florida.

  13. When Honda revealed the GX series of industrial engines, it almost immediately replaced the old, inline style single cylinder engines in go-karts. It was more compact, ran smoother and fitting much better to the constraints of a go-kart. Basically anything "mini" was powered by a GX or its clone derivative. I dabbled in them for a couple of years, hopping up a clone from 6.5HP to 13 HP. Until the clone crankshaft broke and I threw away basically everything below the head. But the fun thing about these engines is: you can source pretty much any part for them. You dont have to waste money on a clone engine and have a box full of parts you wont use. All you need is a fresh block, side cover, a genuine honda crankshaft, high quality main bearings and the cylinder head. Everything else is pretty much aftermarket hop up kits. And the only investment I highly recommend for your build is a genuine honda crankshaft. Its much much stronger than any cheap clone one. Everything else is basically how much you are willing to spend...

  16. Technical yet very clear. Thanks, I've always wondered why the German V-12 was inverted when no Allied engine maker tried this. Lots of stuff in there I didn't even know I didn't know!
    27
  17. The engine was used on a popular type of very portable fire pump in Denmark by the CF (Civil Protection). It could be carried by two men or equipped with a front wheel moved like a wheelbarrow by one man. It worked!
    25
  18. Trying something new is never wrong. I have to see how this works out, being in a hot and loadsensitive part of the engine.
    25
  19. Thank you I have wondered about this configuration & now I know
    25
  20. Maybe it was just me but the pro vs con ratio was definitely slanted against, I hope decision-making isn't based solely on 20% increase in HP. Sounds like this needs more tweaking before being practical.

  21. Former Ilmor (and Ricardo) engineer here. Those pistons were an Alumimun Beryllium alloy and therefore not harmful at all. Ferrari F1 liked to make up rubbish to harm other teams when they could not work out how to make their engines work properly.

  22. Your channel is severely underrated. I hope you get the support you deserve!

  23. Thank you so much for such a great video! I'm a two stroke freak and I waited so song for this video 😁 Could you make a video about heavy duty engines and its durability? I would be greatful 🥰

  24. Thanks for the awesome 3-D, animated illustrations. It is helpful to see the internal parts working. I've owned a '74 2CV for the past 23 years and drive it almost daily during the summer. It loves our local round-a-bouts and puts smiles on just about everyone it meets. Parts are no problem what with several sources along the US west coast. Love the car. Hills are a challenge but most drivers behind you will be patient while you drive in low gear. We all need to slow down a bit anyway!

  25. Great work. I just discovered your channel and sat through every video you made. I love the descriptions and video content are great for education and make it so measy to understand what's happening. THIS video, explaining the operation of the W engine was above and beyond the best one for making such a vastly complex engineering operation of this motor easy to understand. I look forward to your next and future videos. Your channel is the ONLY channel of my over 400 subscriptions that I hae the notification turned on for. Thanks for the effort you put into these. It shows.

  26. So far, i've never seen someone go into so much details, explaining things in a clear manner. This channel has a great future !

  27. Very clever man, fantastic engineering skills
    16
  28. Thanks for the video. According to a 109 pilot there was a valve to isolate the left or right radiator in case it was hit.
    16
  29. Nice design! But I don't believe the claims without duration testing a full size engine. A lot of wear can be caused by different thermal expansion of the block and the piston. And 30% improvement seems just wishful thinking. But you've made a great video!

  30. this is one great presentation bro, thank you for enlightening us about N2O, such useful enfo
    15
  31. Very nice super clear video with all technicals double checked. Keep it up. 👍👍
    15
  32. Love it how detailed it is.
    15
  33. That Red R33 is gorgeous 😍

  34. Cam is driven by a spring loaded split chevron gear, so as it wears over time the cam timing never changes. Also notice no connecting rod bolts. The con rods are slipped onto the crank at the factory by cooling the crank in liquid nitrogen and heating the con rods. Renewing the engine, you’d purchase a piston/con rod/crank set. All new in minutes!

  35. Great video bro, really informative and well put together keep up the good work
    15
  36. Great Explanation and Visualization , its straight to the point and no frills . I wish more Videos were like this without all the padding and such

  37. 7:57 dont forget that the T was a model that was much more limited in it's evolution. a 1st gen corolla, F series, or Civic has little to do with the current one being sold. the only other real challenger is the Beetle.

  38. I liked your video, so I subbed n belled. My Dad is 92 and healthy. He lives with me. His Dad’s 1st car was a model A. My Dad was 5. The Model A cost Grandpa $35. I just asked him. He’s still talking. Lots of stories!

  39. Another step forward. The internal combustion engine still has a lot of potential. The video is also very well done. Hopefully it will be serialized soon.

  40. In Greece there was a Greek-made Citroen Pony. Same engine and drivetrain but with a jeep-like chassis. Heavier than a 2CV, but could easily fit 10 kids for movie runs! That was with the 602cc engine. I learned how to drive on my dads Pony. It was very fun to drive, especially on dirt roads, thanks to the amazing suspension. It would be interesting to get a video on the gearbox of the 2CV, the weird gear arrangement (reverse and 1st were opposite of each other), why the 2nd gear was the strongest, and why you could go from 3rd to 4th 2 different ways (one was the normal way of going through neutral, and the second was moving to the right first through the location of what would've been a 5th gear if it existed). Thank you for bringing back memories!

  41. Would be great to see any comparison and researches that was done by auto makers regarding this engine back then and maybe we would have a chance to understand why they even did not try it as a POC, or if they made a test piece, which results they got.

  42. I think the humble dry timing belt is the best system even today. If maintenance is performed as prescribed, it will never be an issue. Timing chains can still fail and they are much more labor intensive and expensive to replace.

  43. I LOVE THESE VIDEOS, Cause this is the place to go where you wanna go when you think you know all about engines, but theres more to see, and its type of content know one else gives, showing deisgns and internals and explaining in depth from historical point of view to advantage and disadvantages, to all the components, That is next tier level yt creator. Twingle diesel 2 stroke, and mazda patent mixed with twingle? could be cool. LOVE THIS CHANNEL!

  44. You actually understand the engines you make videos of, not just 'this part made this number and that one made that number' like some other youtube folks. And that's why I like your videos so much!

  45. Actually NSU from the early 50's production motorcycles used this system.

  46. I was a young engineer in Detroit at one of the Big 3 OEMs in the early '70s. I remember following some older engineers into an SAE presentation at COBO Hall where one asked what a foreign manufacturer could teach Detroit? Well, I guess they've learned.

  47. This is the BEST video on the Wankel engine !
    12
  48. Great video, and animation. Ver many years, I've built many of these great engines from 36hp to a mild 1800, and never ceased to be amazed of the clever and simplistic engineering. Properly built, it is bulletproof reliable.

  49. Really nice animations, makes everything quick to understand. What a marvel of engineering!

  50. Great video really explains it all so well.
