    moment loading of the sliders against the ring would be challenging to deal with to say the least- would need slotted/rotating pins with enough bearing area to handle combustion pressures- and seals, more seals, more seals…the model doesnt show any load bearing pins/seals, even if ring slots are knife edged to actually touch at max angle, theres gonna be a big gap when perpendicular to ring… sorry for being negative, but good luck… also, better watch the Curie temperature of Neodymium magnet in injector…if it overheats even briefly, its dead

    40% effi. versus normal ok so show the engine you got these supposed numbers from instead of cad drawings, the wankel engine on paper was more efficient then a piston engine but in actual use had poor fuel economy -terrible emissions – slow combustion due to shape of the chamber being long and thin and was plagued with huge seal issues . all i can see here is tons of failure points in sealing surfaces and lubrication problems with an oil burn issue…. anda chain drive on system another major failure point. al you are doing is chasing after the same problems and issues the wankel had the combustion chamber is the main down fall of the efficiency and until you get away from a long thing wedged chamber you wont ever bring this form engine up to it's potential as mazda found out on its wankel

    i just got understood how it works, the offset inner rotating assembly that houses the 2 bars works by moving to the inner part of the bar and when you do that your swinging the outside faster, like how a small wheel at 2,000 rpm has alot slower surface speed as a big wheel spinning at 2,000 rpm and its timed just so it can swing em so it compresses, i think your frictional losses and complexity as well as the requirement of burning oil like a 2 stroke all mean a 2 stroke with an expansion chamber like a dirt bike makes more power for displacement and fuel consumption as well as doing it more reliably and lasting longer over all, 4 stroke reciprocating engine technology these days is so advanced to the point where its the most power dense and efficient and reliable engine there is maybe besides jet engines these days which are also super advanced

    Tho only issue I see with this design is that it's not a "true to form rotary" because it doesn't get rid of the valves that the rotary is so loved for.

  • Reply Shawn Elliott November 30, 2017 at 9:10 am

    Accelerating and decelerating those dividers hundreds of times per second will waste just as much energy as a reciprocating piston. It will also be more difficult to seal.

  • Reply Sherlon Charlz December 30, 2017 at 2:59 pm

    Nice but won't really be a true replacement to the rotary. Intake, compression, power and exhaust this design only does one of these every rotation where as a true rotary engine does 3 of those in one rotation. I honestly can see it making it in the world. But it's a cool design though

    without oil the engine will be destroyed because of heat and friction~

  • Reply 65bug519 January 14, 2018 at 3:47 pm

    a lot of rotating parts that must be lubricated and seal but ceramics might do it, the interesting part is the mechanical advantage during the intake cycle , no other engine does that

  • Reply Benedikt März February 14, 2018 at 2:26 pm

    This design even if deeply thought through, it looses its quality by not beeing highly rotateable, since the old Fashioned Rotary engines, at 9000 rpm, each single rotary part just spins at 3000 rpm ending up destroying less seals.Your machine spins at the speed of output rpm, ending up that each seal have to endure 9000rpm which will definitly result in using up all your seal parts. Plus the old fashioned way is easier to get maintenanced even if you have to completly disassemble your machine to do so. Your type of the "higher efficienty machine" will work better in the low RPM scale, but never get on the level of the old fashioned rotary engine.

    Simply look @ the drive shaft. It goes faster, then slower. How can you expect this motor to compete whit a regular engine if the output is unstable?

    How do you plan on cooling all this?

  • Reply frosty A B May 14, 2018 at 12:07 pm

    I have reviewed your publications. Although theoretically possible, in reality this engine has several problems. Cooling of individual components would be very difficult. Calculations are based on theoretical values and ideal assumptions, real values will be much lower than calculated. For instance, you assume that the temperature of the burned fuel gases will be 3400K. That is not possible. You can expect temperatures in the range of 1800K – 2200K (and that is generous) Adiabatic flame temperature of gasoline in air is about 2400K. That alone will take your efficiency way down.

  • Reply DH Wardani May 20, 2018 at 2:53 am

    While it may be efficient by fuel consumption standards, the amount of moving parts will make the engine extremely inefficient and completely stems away from what the rotary is built upon: simplicity. The amount of moving parts means more chances of breaking down which isn't efficient.

    why does fuel pressure need to be 2000x more psi then normal?the average car runs 35-40 psi so would 2000psi be only In the injector or would the store fuel system need to run this?seems like that much you would have to use metal lines and a super pump that can handle this for hundreds of thousands of miles.seems like using a regular fuel system would be much easier but I don't know nor do I know the reason for 2000psi fp.

    only problem being it wont develope any torque, looks like they made a spinning piston in a cylinder, a rotary's piston moves in a figure 8 while it spin's hence developing coaxial torque around the spines of the crankshaft..

    And really the only problems with wankel is the seal's … they dont hold up.

    2:30 you can’t expect good CFM numbers from that squared off air flow path. This engine will not breathe enough to idle at WOT. And the square “valve” on the blue cam lobe – what is it controlling?

  • Reply TECHO June 16, 2018 at 12:29 pm

    Achei bem interessante o processo… Mas a principal característica do motor rotatório é a questão de não ter válvulas… Válvulas dão problemas é por isso que motores 2t e motores rotatório serem tão bons…. Só minha opinião… Espero que seu projeto continue e progrida… Até mais

  • Reply Some Other Dude June 24, 2018 at 2:51 pm

    Absolutely hopeless. The design doesn't allow for anywhere near enough expansion, and what little expansion does happen must then drive sliding parts much too far per stroke, consuming what little energy the engine captures. This idea has been tried a million times- and there's a reason it didn't catch on. Ask yourself this before embarking on your next scheme.

    Those dividers are exposed to so much shear stress during the sliding friction , they would need to be bearing material with pressure lubrication , you have the force and friction that crank and rod bearings are exposed to during side load forces that will cause this to a fail. It's one thing to push something , it's another thing to push something and have to rely on transfer of energy in a different direction multiplying friction like aerodynamic down force ( drag) while trying to move.

    The internal combustion engine for automobiles will get smaller and smaller and will soon be used only as range extenders for electric vehicles. All the major car manufacturers have plans to phase out gas guzzlers in favour of electric vehicles. Seems pointless wasting time and money on R+D for engines that are to be phased out over the next generation.

    Though the whole point of a Wankel is being reliable by not having any valves and so being able to rev sky high

    This is nicely thought out but does not look like it will provide either reliability or efficiency compared to a modern piston engine

  • Reply Ravi Gautam December 5, 2019 at 1:53 pm

    Delicate Controls/linkages are exposed to ignited fuel. Also ignited fuel will cause shear stress on the follower bar (relatively fixed as compared prime mover bar) because when fuel explodes it creates pressure on all directions equally that to follower bar is moving against the pressurised flow of exploded fuel. Wankel engine also face these challenges to some extent.

  • Reply Ravi Gautam December 15, 2019 at 2:33 pm

    So the thrust on the follower bar will cause decelerating impact on the central shaft.
