Wankel engines aren't just for cars. They are used for airplanes also. You can't power an airplane electrically :/
We'll always need engines, for some industrial purpose or other. Even if we were to move to a totally "environmentally friendly" model. Even if we had electric trains and no cars, storing solar power in chemical form (CO2+water->alcohol?) is sensible for release when there is no sun. And we need efficient engines for this.
Good luck in getting this popular. We need better engines and something like this might be just what we need. I hope you can get adopted by a big or fast-moving company.
cool...I still like the M.Y.T. engine design though...MYT=a 140 lb engine with the power of a big v-8 engine....RAWR...but still burning gas.....we need an entirely better newer fuel..
If this where to have more cylinders you'd have to figure a way to make them synchronize, otherwise all you have here is a mighty powerful dildo motor.
A computer-animation working model may be more easily understood. I am becoming more and more in favor of developing a turbo-prop hybrid power system, but lack the funds and resources necessary to produce a working model of what I have in mind.
@NearAbbeyRoad Okay... for completely electric cars, how do the batteries get their charge? Over half the electric generated in the US is from coal. Coal to make electricity is dirtier and less efficient than the gasoline engine.
@danijlew On that subject how is a modern hybrid vehicle produced? Using electrical power created almost certainly by coal power plants. Does the fact that the hybrid uses less less gasoline (than a modern car of equal weight/power, because older cars are lighter many of them have similar MPG) offset its use of coal-power during manufacture? How many years or miles would it take for a newly manufactured PRIUS or even a fully electric LEAF take to equalize it's "carbon footprint?"
@JDBEDORE a couple hundred miles for a prius, there is a small inverter with IGBTs and the battery is about the size of three regular car batteries. it's actually about 30 batteries in series similar to a drill battery and a small 12v motorcycle battery. a leaf would depend on the source. plus consider they are upscale cars where the buyers would otherwise buy a big luxury car. I agree it's useless if you have a coal plant to save carbon dioxides but that is not the point of a car like this.
@JDBEDORE it's really to save gas. a prius is a big car with a hatchback but easily gets 55-60mpg. plus you get the novelties like not making any noise and a touchscreen radio which appeals to me (well in 2004 when it was new, now lots of cars have it). if you are so concerned about the environment you should walk or ride a bicycle or take the tram if you have one.
Great theory, like 1000 other model engines on YouTube. If you ask me, until I see these things working for real, all that stays theory. Investor thinks pretty much the same.
This Design is good, I can see it working well, the oil may be an issue, due to the "wings" rubbing on the interior walls, how will the oil be sprayed to protect it??
I really like this. I was thinking, "I wonder how complete the combustion will be," right at the 7:15 mark. At that point, not only did I notice how the chamber expands as a triangle shape with the flame front starting at an apex, I heard the narrator mention the good combustion characteristics.
To those who think this is just a variation of a Wankel, you misguided.
yes just a variation of the wankel rotary engine.. which has the research frpt of a major car company trying to perfect it over a number of years. Doubt that this is much better. Wankel suffers from high fuel consumption and high oil consumption. If they made it out of cermaics or titanium it may work better, but the cost would be raised by 300%+
nice work, one thing tho, the angle of the plug, wont that cause the initial flame front to work against the rotation of the engine?
it seem since this has two compartments and fires on a 2-stroke cycle. but works on the 4-stroke principle of seperate exhaustive and intake turns. that you would have to compare this against a 4 cylinder engine. of double the capacity.
It always makes me laff when i see engine developers quoting how efficient the latest engine is ......we had 40% efficiency 70 years ago........the triple expansion steam engine .... today you not run it on coal but have a flash boiler that will make steam in a seconds Dave
Looks wonderful. However I think it'll be a lubrication nightmare. The most it can do is run like a normal 2 stroke engine with the fuel & oil burning at the same time. It did not explain how a forced lubrication system in this design. ... Good work keep trying so that we can surpass our current 20% efficiency gas engine. Thank you.
I se the heat causing problems on the rotary exhaust valve under full load plus the rotor getting hot. Seems no one has come up with a engine as well running as Otto`s piston engine wich has been running well and many have tons of miles ,and hours on them . Supurior 130 rpm piston engine will last 60 years at full load running 24-7 before a rebuild
Reeds are in my opinion the bad thing here..remenber kawasaki was the last to use them way back in the 80's...in compressors they do acceptably mainly because the lack of combustion wich in turn , changes it all
are there some projected specific fuel consumption figures for this? looks interesting but im not persuaded that this design overcomes even the problems with regular rotary engines - main being that its very hard to get a perfect seal in a rotary engine and some economy is always lost. just ask an mazda rx7 owner about their MPG!
I would like to ask you to record it again with a better audio, with somneone speaking a very clear english ( not whispering), so we, internationals can pick up all the informations. Thanks for sharing the video.
looks good, but how do you intend to lubricate it? gas-oil mix?
also, too many seals...one misfire would cause alot of damage...also appears vulnerable to misfires...one stray spark in the electrical, and it will stall. however. its nice and small, and would be great to put in the hub on a bicycle.
Looks extremely complex... How does it perform after 100K kilometers and high revs? Whats the torque and how is the oil-consumption? (problem with the early wankels...)
Electric cars are a waste. We rely on fossil fuels to supply the electric grid, and all that an electric car is going to to is increase the demand on this grid, meaning the power stations will need to consume more of this to supply the cars. Global warming is not stopped, the buck is simply passed from the motoring companies to the power companies. Until we can produce electricity without needing fossil fuels, electric cars should be on hold until then. But research into them shouldn't stop.
@CainG88 But nobody is going to spend money on R&D without having a ready market. Today's electric cars may not achieve much except make their owners feel all eco-responsible, but they are still important because when/if we do implement large scale green electricity production the cars will be ready straight away.
@CainG88 Most of my power comes from river dams. The rest from homes with solar and wind that feeds back into the system. There is not any fossil fuel plants in the area. And on our elec. bill we have the option to get our power from renewable energy as an encouragement to build more wind and solar power.
And why not get a small engine like the one in the video hook it to a generator to keep the batteries charged would never have to plug in and would get over 100 miles/ gallon. Elec is the way
@VCat2006 Not sure till I experimented with different ones. But I like the idea of a small diesel running on veg. oil. Diesels have more power use less fuel and running on veg. oil would be great for the planet. If I ever ran out of veg. oil I could buy diesel at almost any station.
@CainG88 That's exactly what I was going to say. And another thing, the batteries that are needed for electric cars aren't very healthy for the environment either...
It is an oscilatory type rotary engine,like the kauertz one.because of this,it causes vibration,difficult to counterbalance.Forget it,there is the Wankel..
I can't believe this guy has subscribers. He doesn't even bother to respond to comments posted about his video. Go back and look. Not one response from the guy.
It looks like the piston mass is accelerating and decelerating as the engine turns. That negates a lot of benefits of a rotary engine. Would not this cause vibration too Don?
Looks great but it still has the problem of sealing the compression area. A problem that Wankl never fixed and MAZADA rotories still suffer but to a lesser degree.
This seems like it will still have the same high heat loss problems of a rotary due to combustion chamber surface area at TDC. Has this engine run on a dyno? What was BSfC?
This seems like it will still have the same high heat loss problems of a rotary due to combustion chamber surface area at TDC. Has this engine run on a dyno? What was BFSC?
I like the engine and have done the research. You did well, but perhaps having a script and from which you could read thus eliminating the comfort words "umm..." and "ah..." which would make you sound far more professional.
Over-all, I say well done. You explained the principles of this engine style quite well.
The sealing of this system is so complex, thus I am not convinced. As an RX7 driver, I understand where sealing creates issues in 3 dimensions. The piston engine wins because it is so easily sealed.
Wow, I must say, this thing is a pure work of art! The only sad part is that in an actual vehicle or other system you wouldn't actually be able to see it running!
@TheIceychill2 This is a rotary version of the Atkinson cycle, and you're right, that cycle is used in the Prius. However, in the Prius they accomplish the Atkinson cycle using a conventional piston engine with variable valve timing.
The answer to electric car is the new mega capacitor that is currently in development. You'll first see them replace household batteries, AAA, AA and so forth. Next, car batteries and then, electric cars. I'd say 10-15 years they should be able to power a car with them.
definitely the coolest engine I've ever seen, but i wish you had taken it completely apart. I'm still having some trouble visualizing how everything fits together, or could fit together.
@Rangerscott69 I understand and agree with your statement about the batteries and "Coal fire power" but there is also Solar and "Super capacitors" i think are now being used in cordless drills,
@Rangerscott69 The very moment we can place solar panels on the roof to charge those batteries in a extremely clan process, then use the money we did not spend on gas, on something else, and put that money back into the economy without going though the oil companies, this world will be better off. Wow! I bet they will not like that at all. Hence the reason for all the miss information spurring forth in opposition for electric cars.
@GSpotter63 Follow the money... if there is a market for electric/battery/alternative-energy cars then they will make them (because people will buy them and the company will make money). Would you buy a solar panel car if it were $100,000,000? If so, then quit with the conspiracy theories about big oil and buy one... the problem is the tech is too expensive to compete in the market place and for the middle-class to afford it.
@GSpotter63 Also, what misinformation about electric cars? You use electricity which is less efficient, no matter what source it comes from. Also, if it comes from coal, natural gas, nuclear than what's the point? It is more damaging to the environment. Look at the proven SCIENCE behind electricity and electric cars, instead of being all crazy saying that big oil and the media are keeping them off the market. The truth is they are the stupidest invention ever.. they don't solve the problem.
Batteries are cheaper. Efficiency of EV ~70-80%. IC ~20-25% max. EV stores 1/3 energy for same distance. EVs lighter than IC cars. EV motors higher power density than ICs..EV has no drivetrain; motors inside wheels, regen brakes & no idling losses. EV motors run close to max efficiency all speeds, ICs don't. EV 500km range. Toshiba have battery with 80% charge in few minutes. If charge was 100% from oil pwr stn, less oil per km than a equiv IC. Pwr stns 60% efficient. Trans lines 95%
Potentially it could be a very small but powerful engine. Maybe one day...
Electric engines? Until someone invents cheap huge super capacitors (capacitors that has capacity of batteries, but can be charged in few seconds) they can't compare to fuel ones! Cheap but powerfull solar panels could be also nice...
The strongest point of electric engine is that they can easily get energy back during braking. The weakest point of electric engine is that they do not use effective fuel.
Ok,, Soo Im Only Seeing One Rotor, And Seems A Lil Complicated,, But Yet Simple, But Sounds Different.
Soo My Questions Are,, How Does it REALLY Work?, Does it Have Other Parts Or uses More Rotors Or Just That One?, Thus Raises My Question Of, HOW EFFICIENT IS THE ENGINE, In Comparisn With The Rotary and Conventional Engines?, :?
fantastic! finally a unique combustion engine! thank you. and alltho i am sceptical on allot of the main factors "lubrication system/adequit cooling system/ actual efficency/ i cant wait to see an actual running unit!
this kind of seems like a wankel engine but of course without the rotor ( if you dont know about the wankel engine its the same on in the rx7 also know as rotary)
good principle. What about lubrication. as both sides of your 'piston' seal are dry. these will fail. no lubrication. this is a 2 stroke type engine that will require a lubricated fuel.
You don' know the wankel engine otherwise you couldn't say that!!! This engine and wankel are totally different. This is better than wankel for seals and efficiency.
@daniloruggero@daniloruggero The only part of your statement I fully agree with is that this engine is totally different from a Wankel engine;the seals might look better on paper,but what would be the high speed effect on the seals as they are not always in permanent contact with the chamber.( centrifugal force on the seals?).How can you claim better efficiency when you dont have any running engine to prove your claim.
@daniloruggero Mind you, it is so easy to bump up theoretical efficiency number by just throwing in some favourable assumptions, so an Air Standard Analysis efficiency number is not enough,there is no such thing as IDEAL condition in reality; you need a working engine to verify and confirm theoretical calculations
this engine, the libralato, is not the best small engine. the rotary vee is rather the best weighing mearly 75 lbs and rotating at (and above) 25k rpms with an almost entirely uniform torque higher than anyother engine.
I live in the country and electric will not work for me as of yet with current tech. Rotary motors available to the public get poor mpg. If this one can work in a practical environment and deliver reliability, good mpg and is conveniant to use it will have a future. Otherwise it will end up in the dustbin like so many other bright ideas.
True....an electric motor may be more efficient but the same connot be said for the entire system as a whole. When you invent a 400+ mile battery that can be recharged in about 3 minutes...like a fuel tank can......you let the rest of us know.
uh no.. how about we focus on something that we have now that doesnt require bullshit batteries? like hmmm what could we use?? oh yeah WATER, turned into hydrogen, combusts then BAM back into water.
@ZerqTM you do realize that electric cars as a mainstream idea is horible the controls alone are a nightmare unless you know how to troubleshoot and fix (VCDs) and all the motor controls you would need to take it to a dealer with would be inconsevibly expensive if you vehicle is out of its warrenty..
@ZerqTM sure ur average electric motor might cost less than an equivalent power internal combustion engine, but the cost of the batteries, especially high performance oens that you would need to achieve even a fraction of the range and power of a combustion system, make the cost much higher. the very best Li ion batteries have an E density of 0.9 MJ/kg, gasoline is > 32 MJ/kg
@ZerqTM You premise your position on the existence of "next generation ultra high density batteries". Market research shows that the minimum range of an electrical vehicle to reach a tipping point is 120 miles, four passengers and recharge time of <5 minutes. While this may be unrealistic, that's the hurdle to meet.
electric vs ICE, electric takes the cake when it comes to efficiency. The time required to refuel/recharge is simply a matter of circumstance. I for example never need to recharge my electric car away from my home. So for me, my electric car is saving me 6 thousand dollars per year and will pay itself off in two years. I have my electric system rated for 5 years minimum before batteries need to be refurbished/replaced where they will be recycled and made into new batteries.
but have you looked at the cost of replacing the electric system when it goes out and factored that in? and what vehicle is it? homemade or bought from a manufacturer?
Uh, wrong. They have a 7 year 150k mile warranty, and cost like $2k to replace, and there is a $1k core charge, and they are 100% recycleable. Stop parroting bad information from big oil.
If they ever need to be replaced (none have been replaced unless they have been damaged in a car accident) then warranty covers them for a long time. But so far with my 2004 prius, my battery peak charge capacity is at 92% of the nominal charge when it was first produced. I had it tested recently to see how much it has aged. Quite impressive really.
There have been hardly any electrical malfunctions in the prius yet. They are built tough and the controller works under it's rated duty.
yeah I did buy a prius, a used one. I bought it through my friend who is a car dealer and he sold it to me for what he bought it for. I have since paid it off. I love it! Best car I have ever owned and I love driving it. Your next car may be a hybrid or an electric in the near future. It's much much more powerful and efficient than standard ICE.
Actually, the system as a whole is more efficient, due to the power plants much, much higher efficiency compared to internal combustion engines. Battery charge is still a problem though, I'll give you that. We can only hope that some smart guy comes a long and solves that issue ;)
"the system as a whole is more efficient, due to the power plants much, much higher efficiency compared to internal combustion engines."
That's simply not true. Typical efficiency of coal and oil plants is about 33%, whereas efficient 4-stroke engines can reach over 40%. In addition to that, with an electric car, you have to convert the energy twice: from fuel into electricity, and then into mechanical work.
Not to mention what it takes to build and dispose of those batteries...
@DanoD39 actually...supercapacitors may not have higher energy density than batteries (i think) but they can be charged within seconds, a small supercapacitor gives you about 1-3 farads of electricity at your disposal. a large bank of these charged at a 'charging station' will take you for many miles and then instantly recharged with no biproducts as opposed to batteries which will inevitably give you gunk and dead batteries in the end.
@DanoD39 super capacitors. true, they don't have the highest storage capacity to weight ratio (I think it's similar to a lead acid batt.) but they recharge close to instantaneously , now we just need to perfect the MIM diodes to work with nanoantenna's then we have a feasible solar powered electric car.
@DanoD39 you should research Nikola Tesla, he had an old caddy that ran off batteries and would last a very long time, really interesting to be so old.
@DanoD39 Soon you Talk as if science is not evolving expotentially. Carbon nanotube capacitor. Super conducting electronics. 5 years.............................

Do you know how much fuel it needs compared to an ordinary engine?
The fuel consuption (and the sealing) was always the problem of the rotary engine by Felix Wankel.
Next problem was the lubrication. With a mixture of gasoline and oil one could solve this problem but then catalysts won't work (long).
However, I personally see the future in electric mobility. It only takes lighter and cheeper batteries and the times of fuel powerd vihicles are over.

Electric cars are a waste. We rely on fossil fuels to supply the electric grid, and all that an electric car is going to to is increase the demand on this grid, meaning the power stations will need to consume more of this to supply the cars. Global warming is not stopped, the buck is simply passed from the motoring companies to the power companies. Until we can produce electricity without needing fossil fuels, electric cars should be on hold until then. But research into them shouldn't stop.
CainG88 1 year ago
@CainG88 But nobody is going to spend money on R&D without having a ready market. Today's electric cars may not achieve much except make their owners feel all eco-responsible, but they are still important because when/if we do implement large scale green electricity production the cars will be ready straight away.

@CainG88 Most of my power comes from river dams. The rest from homes with solar and wind that feeds back into the system. There is not any fossil fuel plants in the area. And on our elec. bill we have the option to get our power from renewable energy as an encouragement to build more wind and solar power.
And why not get a small engine like the one in the video hook it to a generator to keep the batteries charged would never have to plug in and would get over 100 miles/ gallon. Elec is the way

@VCat2006 Not sure till I experimented with different ones. But I like the idea of a small diesel running on veg. oil. Diesels have more power use less fuel and running on veg. oil would be great for the planet. If I ever ran out of veg. oil I could buy diesel at almost any station.

Sealing.
The sealing of this system is so complex, thus I am not convinced. As an RX7 driver, I understand where sealing creates issues in 3 dimensions. The piston engine wins because it is so easily sealed.
Seal failure? Remove engine.

The answer to electric car is the new mega capacitor that is currently in development. You'll first see them replace household batteries, AAA, AA and so forth. Next, car batteries and then, electric cars. I'd say 10-15 years they should be able to power a car with them.

Electric vehicles are not clean. Batteries are one of the filthiest things you can make. Be happy that you don't live next to a battery plant.
Also to charge the batteries most likely in your area does not come from "clean" energy. Coal and liquid fuels are still #1 in electricity making.

@Rangerscott69 The very moment we can place solar panels on the roof to charge those batteries in a extremely clan process, then use the money we did not spend on gas, on something else, and put that money back into the economy without going though the oil companies, this world will be better off. Wow! I bet they will not like that at all. Hence the reason for all the miss information spurring forth in opposition for electric cars.

@GSpotter63 Follow the money... if there is a market for electric/battery/alternative-energy cars then they will make them (because people will buy them and the company will make money). Would you buy a solar panel car if it were $100,000,000? If so, then quit with the conspiracy theories about big oil and buy one... the problem is the tech is too expensive to compete in the market place and for the middle-class to afford it.

@GSpotter63 Also, what misinformation about electric cars? You use electricity which is less efficient, no matter what source it comes from. Also, if it comes from coal, natural gas, nuclear than what's the point? It is more damaging to the environment.

The truth is they are the stupidest invention ever.. they don't solve the problem.

Batteries are cheaper. Efficiency of EV ~70-80%. IC ~20-25% max. EV stores 1/3 energy for same distance. EVs lighter than IC cars. EV motors higher power density than ICs..EV has no drivetrain; motors inside wheels, regen brakes & no idling losses. EV motors run close to max efficiency all speeds, ICs don't. EV 500km range. Toshiba have battery with 80% charge in few minutes. If charge was 100% from oil pwr stn, less oil per km than a equiv IC. Pwr stns 60% efficient. Trans lines 95%

Potentially it could be a very small but powerful engine. Maybe one day...
Electric engines? Until someone invents cheap huge super capacitors (capacitors that has capacity of batteries, but can be charged in few seconds) they can't compare to fuel ones! Cheap but powerfull solar panels could be also nice...
The strongest point of electric engine is that they can easily get energy back during braking. The weakest point of electric engine is that they do not use effective fuel.

@ZerqTM sure ur average electric motor might cost less than an equivalent power internal combustion engine, but the cost of the batteries, especially high performance oens that you would need to achieve even a fraction of the range and power of a combustion system, make the cost much higher. the very best Li ion batteries have an E density of 0.9 MJ/kg, gasoline is > 32 MJ/kg
dandil 1 year ago
@ZerqTM You premise your position on the existence of "next generation ultra high density batteries". Market research shows that the minimum range of an electrical vehicle to reach a tipping point is 120 miles, four passengers and recharge time of <5 minutes. While this may be unrealistic, that's the hurdle to meet.
Escatonic 1 year ago
electric vs ICE, electric takes the cake when it comes to efficiency. The time required to refuel/recharge is simply a matter of circumstance. I for example never need to recharge my electric car away from my home. So for me, my electric car is saving me 6 thousand dollars per year and will pay itself off in two years. I have my electric system rated for 5 years minimum before batteries need to be refurbished/replaced where they will be recycled and made into new batteries.

Uh, wrong. They have a 7 year 150k mile warranty, and cost like $2k to replace, and there is a $1k core charge, and they are 100% recycleable. Stop parroting bad information from big oil.
pimpb0tt 2 years ago 2
If they ever need to be replaced (none have been replaced unless they have been damaged in a car accident) then warranty covers them for a long time. But so far with my 2004 prius, my battery peak charge capacity is at 92% of the nominal charge when it was first produced. I had it tested recently to see how much it has aged. Quite impressive really.
There have been hardly any electrical malfunctions in the prius yet. They are built tough and the controller works under it's rated duty.

That's simply not true. Typical efficiency of coal and oil plants is about 33%, whereas efficient 4-stroke engines can reach over 40%. In addition to that, with an electric car, you have to convert the energy twice: from fuel into electricity, and then into mechanical work.
Not to mention what it takes to build and dispose of those batteries...

@DanoD39 actually...supercapacitors may not have higher energy density than batteries (i think) but they can be charged within seconds, a small supercapacitor gives you about 1-3 farads of electricity at your disposal. a large bank of these charged at a 'charging station' will take you for many miles and then instantly recharged with no biproducts as opposed to batteries which will inevitably give you gunk and dead batteries in the end.

@DanoD39 super capacitors. true, they don't have the highest storage capacity to weight ratio (I think it's similar to a lead acid batt.) but they recharge close to instantaneously , now we just need to perfect the MIM diodes to work with nanoantenna's then we have a feasible solar powered electric car.
