  • In this video we analyze the powerful Omega 1 engine that weighs only 30 pounds and generates more than 160HP. Something really interesting.
    It also hits 25,000 RPM and has an idle of 1,000 RPM.

    Great to see this! I'm 78 now (damn!) and have always LOVED innovation. Believe this or not I came up with EXACTLY the same design/concept in my twenties and I suspect that I might not have been the first even then (I just loved coming up with new approaches from my early teens in aircraft, boats, engines etc, etc) ! I called mine a 'rotary abutment' engine. As with most of my ideas I didn't/couldn't turn the design into hardware; family, home renovation/DIY, life events, too many ideas=lack of focus plus, lack of cash. At any one time in the world there are many thousands in the same 'boat'.
    Major problems are materials, sealing, lubrication and heat dissipation. I did realise at the time, and treated it as such, that it would be a high speed engine and my approach was to accept 'leakage' without seals, such as the Wankel rotary uses (in a similar way to the way to the way jet engines aren't 'sealed' either).
    Another factor to consider now, is the imminent changes in motive power, with various competing approaches in the mix. At this point in time, even the LIKELY winner is unknown. This increases the financial risk.
    It's strange how life goes though. Coventry Climax became famous in motor racing in Formula1 motor racing, back in the day, and yet its foundation was as a very light aluminium (rare at the time) high revving 4cylinder engine designed for portable water pumps for fire fighters. Later it was adopted for use in the Hillman Imp (rear engined competitor to the Mini). Thereafter Coventry Climax used its technical know-how to work wonders in Formula 1 motor racing! I do hope these folks have the means, time and money to see it through as we never know what path might open up for this engine.
    There's many super wealthy folk in the USA and hopefully one might back it. Remember that the 'Rolls Royce' name was composed from the surnames of two partners. 'Rolls' was the business/money man and 'Royce' was the Engineer!
    I very much enjoyed coming up with a number of engine designs (amongst other things) over the years but should have designed, manufactured and sold new, mass market, household products....much better to make money FIRST, which is key! (Take note young inventors and remember that the initial inventor RARELY makes the money; it is the folk with business/marketing acumen who take up the idea who generally make the money.... if any!) Of course, there's no guarantee for them either! :)
    I did make a small mark in hang gliders inc. powered and you can't do everything in a measly single life! Hey Ho, c'est la vie!!

  • @wrenchforahammer8317
    @wrenchforahammer8317 ปีที่แล้ว +33

    To deal with the tolerance issues when running and hot, the solution is simple and already in use. Forged aluminum pistons in gasoline engines are under sized so when the motor is at operating temperature they will be the proper size. You just have to leave enough tolerance for the metal to expand. As in all engines the efficiency would not peak until the engine reach operating temperature

    • @tanall5959
      @tanall5959 11 หลายเดือนก่อน +4

      One can also tailor the metallurgy of the engine case to allow expansion of the case proportional to the rate of expansion of the rotors, allowing everything to stay in tolerance through a larger temperature range.

    • @skitidet4302
      @skitidet4302 11 หลายเดือนก่อน +5

      Those engines are easier to keep at a constant temperature because you have plenty of room to place cooling and oil ducts and you can cool down the pistons by spraying them with oil from the gallery. They also have a narrower RPM band. They also have piston rings that help seal the gap when the pistons are small, this does not.
      I'm thinking that if the same technology is pushed in to this more demanding role, they would either have to sacrifice low end efficiency by increasing the gaps or they would have to sacrifice top end power by limiting the top rpm to prevent the engine from seizing due to thermal limits.
      Unlike what the video implies, I think the critical gap is not the one between the rotors but the gap between the lug on the male rotor and the chamber. If there are no apex seals there will be a lot of blowby if the tolerances aren't super tight, but if the tolerances are super tight, total engine failure due to seizing will be an ever looming danger. Even a minute amount of slop in the bearing will cause the lug to drag or bounce along the chamber and thus scoring your engine badly.

    • @kingdrizzy8939
      @kingdrizzy8939 10 หลายเดือนก่อน

      youll find forged pistons expand quite alot, although they are stronger, when cold this piston will slap the cylinder wall causing wear. This also happens at extended periods of low rpm when the engine can cool (relatively).
      For this reason, although forged pistons are stronger and capable of more extrememe conditions that make them ideal for racing engines, most manufacters still produce there pistons from cast alluminum as cast alluminum expands less than forged.
      For an engine like this that is reliant on tolerances for adequate sealing, the engine would need to run at a near constant temperature, or use materials with a low thermal coefficent of expansion... such as titanium.
      Forged alluminum expands to much for this application.. unless the engine is desighned to operate at a constant temp/speed.

    1)A relatively large area is being presented to the burning air fuel mixture. 2) Titanium is great but its going to take a little bit more than just that material to make expansion by heating go away. There are ways I can see but they are not showing it. 3) going to need to work on optimizing the side to side movement of the fuel air mixture. Not going to calculate at this time, but allowing the compressed fuel air mixture to expand through the transfer port since the velocity of the mixture is no higher than the local speed of sound this limits the rpm of the engine. Going to have to think that through a bit since the inertia of the fuel air mix might be used at this point to simply relocate the gas... I could be wrong here, or they might not be including certain details. Appears that this might be fun

      @SupernovaSpence ปีที่แล้ว +1

      I think you are spot on. I would suspect that at high enough rpm’s, we’d exceed the speed of sound through the transfer port. I don’t think scavenging through the transfer port like you described will be possible as the air is being forced to stop due to the rotor disk that closes the port… that and the change in direction the air has to make going from the intake side to the combustion side.
      And I do see cooling being an issue. They claim 60% efficiency but that just means it will take longer for the materials to heat up to the same temperatures minus the heat rejection capabilities. And I don’t see how cooling this is going to be easy either. Maybe it will be cooled purely through the oil and then it will have an oil to coolant heat exchanger before finally getting air cooled?

      As with the last "revolutionary" engine, this 9ne too suffers from impossible seal issues.
      Consider the wiping seal on the outside of the lump on the male doughnut..
      For most of the revolution it wipes the inside of the engine block. Then it is in free space until it mates with the notch in the female doughnut. Then again, free space before returning to the engine block.
      It's the unsupported free space transitions that have all the issues that a Wankel engine has and more, not fewer.
      Piston rings are here to stay for a whole host of bloody good reasons.

    • @KenFullman
      @KenFullman 11 หลายเดือนก่อน +2

      @@dougaltolan3017 I think you overestimate how important that seal is. In a conventional engine, the rings are there to prevent blow by leaking into the crank case. When you look at the rim seal in this engine, some leakage would be acceptable without any issues.
      Consider how a hydraulic gear pump works. They have cogs spinning inside a round chamber and rely on absolutely no seal between the teeth and surrounding body. They can produce some pretty huge pressures, despite the inefficiency. I know the viscosity of the fluid plays its part but any "blow by" only reduces efficiency. It's not absolutely critical.

    There was a similar engine concept studied at Ford research lab from 1978 till 1981. The basic idea was to separate the intake and output so that each could be optimized. It failed for a number of reasons which I can see are common to this engine. First, there is the problem of residual volume - that is the amount of compressed air left in the input side. In a conventional piston engine it is not a problem, all the compressed air is used in the combustion cycle. In this engine the residual air is not zero (non zero input part fits, volume of the transfer valve, etc.) and this will waste a lot of energy, limit the max compression ratio, and the compressed gas will expand back on the input stroke and, thus, limit the air intake. There are many more concerns that I see (leakage, differential heating, heat loss, differential thermal expansion, etc.) but I do not have the energy to type all the details. Nice concept but I doubt this engine will even come close to the efficiency of a standard piston engine.

    Interesting concept that merits funding for study. Issues: high combustion chamber surface area to volume ratio - you'll suffer more heat loss than the new 4-cylinder engines do? The 270 degree push is a huge advantage. Diesels and direct injection engines have a longer push than upstream injection engines, but this new engine more than doubles the swept out angle of the push. The surface area of the push is beyond tiny, compared to modern "oversquare" engines, so higher combustion pressures would be desired. You mentioned seals being an issue - very much a big yes to that. Seals are what made the Wankel engine die from EPA Regs. Trying to "tight tolerance" the very long seams and the vital single tooth "chamber separator" ...beyond daunting. Possibly would work for small engine applications, and for aerospace.

    This engine exposed here has no crankshaft, or pistons. It cannot be classified as a "stroke" type engine.
    I believe it is a two cycle rotary engine. It has an intake and exhaust cycle that produce power in a cycle blending combustion part of the engine rotation. That could be referred to as a third cycle; making it a 3 cycle engine !!

      The biggest issue with gas turbine engines is that they lose efficiency rapidly when they are scaled down to the range useful for automobiles. They also have a slight issue of consuming nearly as much fuel at idle power as at rated output, which makes them even more inefficient when used to power an intermittent load like a car.

The "technology" for electric cars has been around since 1880 but lost the battle to the internal combustion engine this was not because a political edict or corporate tax break for the greenies this was the market at work. Lets jump forward to today what is driving the market? The greed and ignorance of corporate politics "combustion engines must be banned etc" FORCING the market into an uneconomic underdeveloped mess meanwhile actually doing more environmental damage than before. "How" you may say and for dint of argument every part of an expensive and over rated Tesla is produced using electricity from fossil fuels and in this case mainly coal. So all your useful product energy comes from fossil fuels so it makes sense to develop super efficient engines until such time that the "electric car" has an economic and practical battery / motive force that actually is more efficient than the best fossil fuel engine then and ONLY then are you actually reducing the grid load and the turbines that power it.

    When you think about this engine's light weight and performance it would be a great companion to a high-performance hybrid car or SUV. If a rev limiter was used it would remove overheating the 2stroke engine retaining the specified tolerances and protecting seals. Hybrids don't need excess high revs but a constant voltage sufficient to keep generation of current to the batteries. the weight saved would improve efficiency and extend range.

    Verry interesting. As a hydraulic engineer, I wonder is a tolerance of only 0,1mm is realy close enough to archieve a high efficiency. An effinciency of 60% seems too good to be true, as you also asume.

    A very interesting concept, but I wonder how much torque these little things will produce. While each stroke is over 180 degrees, the total amount of airflow looks minimal.

      Power is the only important metric here - you get more torque less rpm by gearing. That being said I doubt it will come anywhere close to 160 hp.

    @CrotalusHH 11 หลายเดือนก่อน

    Even if you don't have tip seals, and I am skeptical about a .1mm gap being tight enough, you still need side seals so the friction is still there. They don't mention anything about cooling, there doesn't seem to be much of a water jacket. The high RPM is the only reason they have Hp ratings that high. I bet the torque is pretty low. They are running it with external power also, so will it really idle on it's own yet?

    I wonder how the compression and combustion chambers and the rotating valve would be sealed. If liquid lubricant can't be used for the purpose, then the rotating parts might have to be surface-treated with a solid material that can accommodate for thermal expansion, like a wax. The engine is based on a great idea, but it might require materials that don't exist yet or are not suitable for mass production.

    It looks to me like those mating knobs and holes could seal well enough to remove inside contact surfaces all together. What I'm concerned with is cooling the thing and It doesn't look like lubrication is well thought out. I'm not surprised it's spewing oil all over the place in the video, it probably has modulating oil pressure for each cycle or part of the cycle.

    Kind of like a vane pump.
    I think this has been tried many times before.
    One major problem I see is where the two round rings meet, they have to be tight enough to hold a certain amount of psi which is no problem with new parts, but over time you will have carbon build up just like the top of any piston, but with a normal piston carbon build up on top will not effect the psi because they have rings on the side. This engine will work but I see it losing its psi for combustion fairly quick.

    In the footage on the unit on the test bench running, unless that is the starter motor (lol huge) I am 95% confident that it is being driven by the pulley and machine in the background. That being said it was obviously compressing and igniting so hope this one actually turns into something

      Motorcycles with this and even more power already exist. Even if it turns out to just be 30 pounds, which they haven't proved and I doubt they will, it will still only be a 50-100 pound difference compared to a regular piston engine of same power. Not mcuh of a difference as bike + rider weight maybe 600+ pounds.

    How do they prevent misfire while injecting fuel? Because bar means nearly 14 atm and means 14/1 compression. And I think it may cause ignition as diesel engine. Already there is problems to applying hydrogen fuel to gasoline engines because of these problems. And with this 14/1 comression rate it looks like bigger problem.

  • @Killerean
    @Killerean 11 หลายเดือนก่อน +1

    It shall be known as "Seal Eater".
    All these rotary like engines have one problem - huge huge seals experiencing huge massive pressures. It's all fun and games until you have to seal a spinning chamber or a large disc shaped rotating object. It all has to do with angular velocity and such which causes differential wear. It's the same reason why rotary engines can only do like 120k km before they need a complete rebuild. Compare it to regular diesel engine block that with basic maintenance will at 1M km likely outlast any of its adjacent components and you know why true "engine revolution" didn't happen since Diesel invented his cycle.

  • @LandyAndy62
    @LandyAndy62 14 วันที่ผ่านมา

    If it works at all, and they can get around what looks like some serious cooling issues, the power curve would make it unusable at lower revs for doing any work and the torque would near useless. Clever though!

  • @Russell_and_Rosko
    @Russell_and_Rosko 10 หลายเดือนก่อน

    Flawed understanding @ 4:43 - the valvetrain is balanced ie spring pressures are equal between cylinders. So for every spring that is opening a valve there is a spring using equal force closing a valve. There is resistance from these cycles, but it is not from spring loading.

    I looked into this engine quite thoroughly about the time when the prototype was completed and filmed. While the design is impressive for the reasons that are the basis for the claims, the problems may be insurmountable. The stated clearances of .004" are much too loose for adequate sealing yet present dimensional problems using conventional materials. Figuring the original effort would be forced into abandonment, I searched for a set of solutions to the various problems and eventually walked away. Even exotic ceramics fell short. My hat's off to any engineer that can make this engine a marketable reality.

    From the simulation, the rotors seem to be fully in sync. So, I can't see why they can't touch to form a more complete seal (that oil would not basically complete.) You mention should they touch they would jam, and I can't see how that would occur. Metal expansion? Wouldn't the gears and their attachment simply be modified to handle that slight expansion via mounts? Oh well, guess that is why my specialty is communications/electronics.
