Hearted Youtube comments on Future Vision (@F_Vision) channel.

  1. Guess this is more of a 2-stroke oposite pistons engine... Another of those videos

  2. As a direct engine replacement for the typical engine-transmission arrangement, maybe for subcompact cars (smart car, mini cooper weight class) or motorcycles, yes. For larger vehicles (civic and larger) no. However, this would likely be a very good design for a hybrid where all it is doing is turning a generator to feed power to an electric drive motor and battery pack. Also this would be a great small package for your typical back up generator where a steady rpm is held for long periods of time.

  3. The "One Stroke" aspect is pure marketing. This is an opposed piston cam engine. The arrangement is interesting and unusual, but not revolutionary. The thing is opposed piston engines are typically pressure charged to assure good scavenging. That leads me to believe that the blower on their example Miata isn't just there to make more power, but is a vital piece of the package. Good video explanation of an interesting mill.

  4. IS THIS FOR REAL? THE IDEA IS NOT NEW, I SAW PLANS OF A SIMILAR DESIGNED ENGINE 40 YEARS AGO, BUT STRUGGLE TO SEE HOW THE PISTONS ARE SECURED TO STOP THE OPPOSING PISTONS CRASHING, THERE IS STILL NEEDS FOR CONNECTING RODS. ALSO THE POWER DELIVERY TRANSFER FROM THE PISTONS TO THE WAVEY ROLLER COASTERS DOES NOT SEEM AS EFFICIENT WAY OF ROTATION AS A CONVENTIONAL ENGINE.

  5. We've leased the Honda Clarity Fuel Cell. & we own a Tesla Model 3. I was excited by Fuel Cell tech 10yrs ago. Now I'll never own a Fuel cell again. Reasons: 1. Fuel Cell require maintenance ever 6mo that cost hundreds of dollars. Our Model 3 requires no maintenance. 2. Fuel cell stations are few & far between & not growing fast enough. We can drive our Tesla anywhere in North America with the ubiquitous Supercharging Network. 3. Coming home to charge is so much more convenient than having to go to any type of filling station. 4. Tesla tech & safety & performance makes all other cars seem like a rotary phone vs. a smart phone. Having driven the Clarity Fuel Cell for 3 years... this is a valuable comparison for those interested.

  6. The Swiss Railways are 100% electric and have been for over a century. When I was a kid, in Southampton, Hampshire, England, the local milk floats were all electric. It's not a new idea. The reality is that the internal combustion engine is a very complex monster which needs endless servicing, repair and oil changes.
    26
  7. Interesting design. Regarding torque output, does it need to be poor at low revs? I use to own a 1000cc V-Twin and the torque output from that was pretty insane from just 2 cylinders. I suppose it all comes down to design. But you are right, engine design seems to have got stuck in a loop. This would be pretty cool to see on a production vehicle.

  8. Smoke and mirrors. If you need stored electricity to convert water into hydrogen and oxygen for internal combustion you are simply adding another state transformation into the total energy system of the car. The transformation, no matter how efficient will consume energy that could be used to directly power an electric motor. An example of more is less. We already have a shortage of clean water and shifting energy resources to produce hydrogen is not a win-win but rather a loss when you look at the total process. This will never get off the drawing boards.

  9. This fits into the cam type of barrel engine. Barrel engine designs have been around almost as long as conventional IC engines. Most proposals have been for aero engines. One attraction is smaller cross section. None of them ever went into production. Their one main enemy has always been heat. Now could this work as a range extender. Yes it likely could. But so could a small fixed speed gas turbine.
    23
  10. hahahaha. Reminds me of the "Company X is testing a new battery that will give four times the range" meme that always appears in YouTube videos on EVs, and then 2 weeks later you never hear about it again.
    23
  11. There are 1-stroke internal combustion engines - they are called jet turbines.
    19
  12. It is impossible to have a single (or "one") stroke piston driven engine as the "stroke" refers to the direction the piston travels. This is a two stroke piston driven engine as the piston travels "down" (one direction/one stroke) on the power/exhaust stroke, and then returns "up" (one direction/one stroke) on the intake/compression stroke. The turbine and rotary (Wankle) engines could possably be considered a single stroke engine because their propulsion mechanisums travel in a circle (one direction). But they are based on a diffrent consept.
    15
  13. A true "one-stroke" engine would be a gas turbine engine. Where intake, compression, combustion, and exhuast are all occuring at the same time, at all times. Thus, we are left with just one process or "stroke" I dont think a 1 stroke piston engine could exist, its operation is contradictory to any less than 2 strokes, as no matter what the piston will always need to oscillate between up and down, strokes 1 and 2.
    14
  14. Right, so rather than just using renewable electricity to power stuff, we should use it to split H20 to create H2 gas that needs to be physically transported, lose major amounts of efficiency to convert back to usable energy, need to store, and if burnt, get back to pollution like NOx, etc. Great plan.

  15. The only current series car engine that injects water into its cylinders is by BMW -- a racing engine in the M4 CSL. It uses water to improve the combustion of gas (by absorbing heat and expanding). Toyotas prototype engines runs on hydrogen (H2), not water (H2O). BMW had such an engine in the early 2000s with the BMW hy7, 12 cylinders, liquid supercooled H2.

  16. I saw a hydrogen car in the late 60s , the oil companies bought the patent and it vanished
    13
  17. Sorry but how do EVs struggle to match the performance of gasoline cars? Virtually all affordable high hp cars are BEVs and if u compare the performance of a 150hp ICE Car to an 150hp BEV the latter feels so much more powerful, due to no shifts and higher torque... Still cool video tho..
    12
  18. Hydrogen would be great if there is somewhere to actually buy it. With only 2 states having very limited places to fill up, cross country travel is impossible. Until infrastructure is built an EV is a much better choice for now. As an owner of an EV I would like to see fast chargers everywhere. I have a trip to Mesa Verde coming up soon, but driving an EV will add almost 2 hours to the drive time, with only slow chargers in the Park. This will make it much more practical to drive our hybrid for now.
    12
  19. This is an interesting concept engine that has potential. The thing that bothers me is that in the video, there was clearly a supercharger attached but no visible drive belt actually driving it. The 2 stroke diesel that's still being used today uses a gear driven blower for operation. 2 stroke engines operate on a pressure differential for the intake and expulsion of exhaust gases. We don't know enough about this engine to know exactly how this works. If this engine does in fact have a functional supercharger attached, then where was the belt drive? I like the engine design myself, but I think the designer is trying to over-sell it. 120hp on a opposed piston naturally aspirated engine displacing 500cc is a bit hard to believe without a power adder of some kind. I could be wrong but my years of engineering tells me that something is off with this.
    12
  20. This is a opposed piston 2 stroke engine, those have been around for more then half a century in large diesel engines...

  21. Hydrogen powered vehicle will always be 2 to 3 times more expensive per km than a battery powered vehicle if green hydrogen is used. Nobody with any common sense will buy a hydrogen powered car if there is an option of an electric car.
    11
  22. Hydrogen makes more sense over electri c
    11
  23. I think hydrogen may have its place in public transportation. All the vehicles will return to depot to fill so it doesn’t require many stations and it will be handled and maintained by professionals for best safety.❤

  24. I would call that a cam plate, instead of a wavy component.
    9
  25. Seems a fair few companies are adopting H2 which is decent progress 👍 Ultimate H2 engine would be a 6-stroke all ceramic, mental efficiency.
    8
  26. Because of no HYDROGEN infrastructure in US, “why not put a hydrogen refueling station at each Toyota dealership?” Elon Musk put in his own electric recharging net work.
    8
  27. I would think the pressure on the "wavy thing" in trying to convert energy to 90 degrees would be very inefficient.

  28. I love hydrogen! There will be hydrogen everywhere! I hope Toyota develops a water engine too where all you have to do is add water.
    7
  29. Until we can make hydrogen without using ENORMOUS amounts of energy, its a waste of time.

  30. The company has openly stated that their engine is more similar to a two stroke but works as a single stroke; it has the direct injection of a two stroke without burning oil in the same way as a two stroke. Additionally, one of the ICE institutions also said it is worth calling it a one stroke in light of this.
    7
  31. Thanks for the video! I am curious about long-term reliability/performance tests.
    7
  32. The direct fuel injection rather than fuel injection before the intake valve is going to make this engine not last long at all. The carbon buildup is going to be ridiculous.
    7
  33. it has been proven, time & again that a engine that runs on water is perfectly feasible by numerous inventors .... who then where taken out... The challenge is NOT to make such a engine, but to introduce it into the world... And this can only happen when the powers who oppose this technology have been taken out...

  34. So Shell quietly shutting down its hydrogen stations is a bit of a mistake then? Hydrogen is a perfectly effective 'battery' but it is inefficient in creation and being bypassed by real batteries. The drive to put hydrogen into cars is a dream of the fossil fuel industry and will only come true if somebody can triple the efficiency of making (or using) it without using fossil. In that event of course the oil industry won't benefit, although the barons will no doubt transfer their cash to other industries. Hydrogen car development is a bit like developing a horse that will run at 100 mph.

  35. I want one.

  36. So it's the Hydrogen engine. This makes more sense because the raw materials are readily available.

  37. Ill hold on to my hybrid till i see where this EV vs Hydrogen is heading towards.

  38. In 1900 there were hardly any petrol stations and petrol was often bought at chemists. But demand grew and so did the petrol infrastructure. It'll be the same with hydrogen I expect

  39. Swash plate is as old as the hills and a one stroke engine has a double acting piston. A steam engine of the double acting type is a one stroke engine. An engine with the cross head to conrod set-up with a blower for scavenging both ends might work as like it did for the two stroke diesels that had a wet sump. Every tdc is a hit and every bdc exhaust leaves the top and more fresh charge on the side. That engine has powered torpedos since at least ww2. Some used compressed air and others actually had an air tank so it could burn fuel. It's a cool engine but not a one stroke and certainly not new, the pioneers from a hundred years ago behind this thing are long gone.

  40. Interesting vid! Even if it is a little weak in the Miata, remember it is only .5L. Why limit the displacement to such a small size if low end torque is a concern?
    6
  41. The conversion of H2 into motion is fine, and H2 combustion vs battery-electric motor can be competitive. But there is still no answer to the extra cost of H2 storage and transportation/transmission. The cost of H2 generation is getting better but storing H2 and sending it to the pump is still very inefficient and energy intensive. So like Nuclear fusion, it is a promise that will change our life 20 years later - exact same answer 20 years ago.

  42. WOW!!!! TOTALLY AWSOME!!!! THE V8 IS ALIVE AND WELL IN 2023!!!! THANK YOU SO MUCH!!!! YOU GUYS MADE MY DAY!!!!!

  43. Hydrogen fuel car is best option...as no charging required foe ev....hydrogen fuel can be cheaper by producing by bio process at sea by sun light

  44. Can't wait to see these cars on the road

  45. I am glad to see Toyota continues to pursue this technology as it is much more sensible and sustainable than electric vehicles. You detailed all the cost advantages as well as limited need for scarce resources, lighter vehicles and extended driving range due to quick refueling time. It is the only viable option for heavy equipment such saw agricultural tractors, combines and construction equipment that runs up to 24 hours a day and has to be dependable. Again, Toyota leads the way while American car companies follow the government mandates blindly.

  46. How many people believe toyota is next nokia.

  47. Hydrogen is an expensive and dangerous gas. One leak, and you get an explosion. It is expensive to manufacture and transport. So the customer will pay premium price for this gas. It might be affordable for industry. But not for passenger cars. Electricity can be made anywhere there is sunlight or wind. It is convenient and relatively safe and affordable.

  48. Too complex compares to EV. and EV is envoling faster in battery technology as well.
    5
  49. Toyota is ahead of Honda when it comes to hydrogen
    5
  50. Hydrogen engines are good for taxi, post office, local delivery company such as Amazon because it's easy to fill up with hydrogen.
