I had a Mazda RX3 in 1974. It was a one litre lime green rocket.

Excellent reportage! Compared to any other source on KZread, you have given much more detail, on the latest developments from Mazda. Thanks, and please - keep up the great work!

This reportage should be put into an article!

Can't wait! This sounds very exciting! On another note, the hybrid engine should be available for light aircraft or even a 6 place General Aviation aircraft with a twin engine set-up. Huge on torque and continuous running power, low on fuel consumption and simpler to overhaul, it definitely can become a game changer for GA. Kudos Mazda, what a lovely effort!!

So combustion engines comes back ?? I would like to hear directly from Mazda whats going on.

Very well presented.

Rotary engines in hybrids will be a game changer, especially if they also allow plugin charging of the battery.

@@stefanweilhartner4415 Yeh right, keep drinking the kool-aid. EVs being charged using diesel generators because its all about how it looks not how it is and stagnant EV sales driving all but the largest manufacturers into bankruptcy together with charging network providers.

Just hope this engine won't go the same way as the much hyped up skyactiv-x.

The Liquid Piston rotary engine is a vast improvement over the Wankel style rotary. The LP engine is basically the Wankel/Mazda rotary turned inside out. Instead of a triangular shaped rotor and a peanut shaped case, the LP engine has a peanut shaped rotor with three tip seals on cusps in the case dividing the case into three chambers. With stationary tip seals, there is no longer any issue with getting oil to the tip seals to keep them lubricated. Say so long to weep holes and high emissions not to mention the need to constantly refill the oil tank to replace the oil that is consumed keeping the tip seals lubricated. Also the shape of the rotor and case results in a period at TDC when the rotor seals the combustion chambers in the walls of the case at the moment of ignition so that combustion occurs at a constant volume. This result is a much higher pressure increase due to combustion than a spark ignition engine. Combustion is largely completed before the combustion chambers are uncovered and the power stroke begins. Because of this the thermal efficiency of the LP engine is far higher than the Mazda type rotary. So instead of a rotary engine getting less mpg than a piston engine, the LP engine will deliver even better mpg than the best current piston engines. One thing it does share with the Mazda rotary is that the power to weight ratio is much higher than a piston engine. So the LP engine would make a much better range extender engine that any piston engine. And with a much higher thermal efficiency than the Mazda rotary but with the same or higher power to weight ratio it will make an even better range extender engine than the Mazda.

Well that's not a problem; the problem is, what's their strategy to getting it to wide market adoption or use? Why are they not getting it up and going with some new vehicle or old vehicle manufacturer, in a hybrid combination or pure form? It could by now have been deployed in the general aviation sector at least, given its extremely wonderful numbers and of course the great possibility of accessing VC funding in America as compared to other countries. So the problem might not be the engine itself, but rather the founders who may be ill advised on how to push their invention to market as highly needed. Making paydirt is great but if nothing is forthcoming, it'd be better to be more realistic on their patent pricing approaches, get more innovative, collaborate with developers etc and have long drawn returns when outright purchase pricing is too high.

"vast" improvement...the tip seals still wear out dummy, getting oil to them isn't the problem, but nice try.

amazing, hope will available soon

Very promising n encouraging development.

i still have questions of the desadvateges about reliability,durabillity,oil an fuel cunsumption and emission.

Bit like comparing a 1970 petrol engine to todays sky active 2023 engine. So if you compare 1970s rotary to what the video is about it quite believable that a purpose built constant speed engine would reach 1lt per 100 km the improvements in materials manufacturing and design would mean it is possible. If so it would be a real game changer for Mazda.

Hopefully there will be an converter kit or the newer housing plates for the 13b. Would love to upgrade my `07 RX8 with this newer technology! :D

My understanding is that a constant RPM is the exact best way to get maximum efficiency and longevity from a rotary engine. This, then, would seem to be the ideal way to employ a rotary engine in an automobile…as the motive force that drives a generator that produces electricity for electric motors that actually propel the vehicle. And a very significant aspect of that “efficiency” is the fact that this particular RPM will elicit maximum fuel economy from the Wankel engine. Maximized fuel efficiency and minimized wear…that’s what it’s all about.

theoretically yes. but what mazda delivered is far from energy efficient and EVs drop in prices fast.

Why's the spark plugs so close to gathe ?

As a petrol range extender to an electric car is a great idea due to a single rotor design . But as a pure rotary engine in a car no. My memory of driving an RX7 was no torque in the engine you had to rev the nuts of it and of course down goes the fuel economy. Very smooth though but high oil consumption.

I greet you from Algeria. Question: Is the transmission in this car similar to Toyota? I mean the planetary and sun cluster in Toyota. Is it the same as Mazda? I mean the transmission in the MX30REV engine. It has the same technology as Honda and Toyota. Thank you

Chasis of this size don't make sense, because the engine's so light. Even if you make it 2, 3, 3.5 liter. Which will give 600, 900, 1200 hp. Rotary engines only make sense on a car like sesto elemento, or with a supercharger.

Its technology I already knew, and has come of it.

@@user-zt8id8cc1k your comment is all hear say ...no proof wherever of thermal efficiency improvements. Im not doubting that these engines are not a good design.. What I'm saying is their claims are not back up by factual evidence. If you look at my device it's back up with evidence of a increase in thermal efficiency.. It delivers a cleaner burn and a more complete combustion of all the fuel consumed, which improves power / fuel consumption and reduces emissions. You can see the the improvement by the reduction of soot production.. Without Green Vapour Draw engines require emissions control systems to reburn partially burnt fuel or trap soot. Most engines leave black soot in the exhaust tail pipe. Soot is unburnt waste fuel. Less soot is a thermal efficiency increase increase.. thats hard proof.

When are Mazda taking orders ? They can have mine now.❤

Why don’t Mazda add in a plug in facility?

Don't make another skyline (or even worse GT-R or lfa) with a non-existing engine, or in the wrong place. The engine feels right and simple when you weight-shift. The chasis doesn't. You need a spindle point. And the needed weight changes with the aplication.

The 1998 arctic cat snowmobile had a Wankel motor in it.

Excellent idea. But still expensive.

I want to enjoy the running of a rotary engine. If possible, drive the tires with a manual transmission that has a direct feel. I don't like running on electric motors.😙

Great idea Mazda saved my money for some else 😂

Rotary is the absolute cheapest way to make a supercar. So where is it?

All I see is HEAT issue ... Generator attached next to engine ???

Is this the same technology as the LiquidPiston engine?

@Enter-wl3zf

Ай бұрын

Not really. Both the Wankel and Liquid Piston designs consist of a rotor inside a housing and were discussed by Wankel back in the 50s. The manufacturing methods did not allow production of the liquid piston design back then. You can think of the liquid piston as somewhat of an inverted Wankel. It’s way more efficient than the wankel and more efficient than Diesel and Otto cycles. Furthermore the power density is even higher than the Wankel. The latter is very power dense - Rx7 using a 1.2l Wankel competed with 3l BMW and 5+l muscle cars back in the 80s.

👏👏👏

😉👍

The problem with emissions still remain. How do the engineers of Mazda solve lubrication for the apex seals without burning oil?

Thats what the ceramic anti friction coating is for, wiider apex seals and redesigned oil delivery to eliminate the old tech oil consumption issues and improve the longevity and reliability and economy.

Why waste time with oil burners , they have had their day.

Showing a Mitsubishi 3000GT/Dodge Stealth instead of a RX8😂😂.

i dont believe that 1l/100km, thats maybe when that car is running on battery power alone while the i.c.e. engine is idling without charging the battery. i guess with the engine charging the battery it will be like 10L/100Km.

A Swedish Motor Journalist, owning an NSU RO80, told a Danish Journalist, that his - third engine was fine! NSU never managed to make a Wankel Engine function, and only Mazda could make fine engines, from the Patent!

Why don’t mazda add in a plug in facility?

I hope the transmission is not garbage CVT.

❤

I am rather sceptical

235 miles/gallon, is good enough for me.

theoretically good, practically the mazda serial hybrid with the wankel is pretty bad regarding energy efficiency with 5 year old outdated EV tech. it is 5 years too late. it cannot compete with new modern fast developing EVs.

1/l 100km? Might be, if the engine is not working! 🤗

Send me one only then can I honestly say anything HELLO MAZDA 😎🤓🤠🇮🇳🙏👏🙌 SEN MY VERY SINCERE PRAYER'S FOR YOUR SUCCESS 4 DESERVING IT 🙏 PATIENCE THAT YOU SHOWN SO FAR IS DESERVING 💥👊🙏👏🙌

I'll believe it when I see it. Just my opinion based on my age and wisdom.

But I seen I like

Like battery development.. manufacture is "just round the corner"

This is not how the new engine is going to look like. Turn the form of the combustion room into the rotor and let it spin into a triangle.

Same design as Nissan E Power. Except they use rotary.

Rotary engine and efficiency? No say more. No way man no way.

Densité énergétique de 1 litre SP95 est d'environs de 8kw. une voiture électrique dépense en moyenne 15 kw au 100 Km avec un rendement moteur de 90 pour 100.. Conclusion , ce moteur thermique rotatif doit plutôt consommé au minimum plus de 4 litres avec un rendement proche de 45 pour cent..... Pour moi , 1 litre au 100km , c du FAKE-NEUWS

when Germany stopped producing these Wankel engines, later when Mazda followed suit, the problem was not efficiency but reliability, ANYWAY BEST OF LUCK

1Liter pr. 100km is that oil comsuptium

1L/100Km❓ FORGET IT ‼️

They mean to run 100 km with fully charged the battery for 85 km.. And the last 15 km... Just use "ONE" litre of Gasoline.. (end of story) ((And the Pig cannot fly.))
