as Ernie Brink said, by changing sparkplug hole geometry by a very thin flat hole (height of the hole will have the same thickness as apex seal) , but too narrow hole could diminish the effectiveness of the spark,I think we can go bigger in the height of the hole without really having consequant gas exchange between compression chamber and exhaust chamber. Other ideas from Ernie Brink are very interesting and pertinant and there are still more possibility to improve the rotary engine

great info when you line up a apex in the leading plug hole you see two chambers at the same time HEAT IS NO GOOD so two keep your turbo and engine in great shape you must stop the flames that are inside the engine before it ever comes out of the housings
The way Ernie Brink described it, it makes sense that it would greatly minimize if not almost eliminate compression & mixture loss as well as reduce exhaust temps. Reduced exhaust temps would also translate to a cooler motor.
One of the fundamental flaws in the Wankel design was the troublesome shape of its internal components... cylinders and spherical shapes are ideal for ensuring even and consistent thermal expansion and contraction and the clearances between the moving parts, stationary parts and most importantly the sealing parts... Like the Newcomen steam engine, one of the Wankel's major flaws is that it is required to maintain high temperatures and colder temperatures with in the same housing, high wear rates and low thermal efficiency is the end result.
By this thing, I meant the whole engine. I understand those are exhaust pipes that are glowing hot. What I mean is, when you're doing a dyno tune, you have a giant fan keeping the engine cool. I was just asking what was keeping this engine cool. Thanks for the snarky replies, though. Always appreciated.
There are advantages and disadvantages. Low thermal efficiency , but very high volumetric efficiency, low weight, small packacking, less moving parts, smooth operation.. The high exhaust temps make them perfect for turbocharging, which then captures some of that energy, and puts it back to the intake side, effectively increasing compression ratio, effectively inceasing mechanical efficiency. It's easy to hate on it.. Only one manufacturer put any effort into it. If rotarys had the billions spent on research that reciprocating engines did, I bet they would be farther along... Fuel efficiency was the death of it.. But let me tell you.. they were FUN AS HELL to drive... Smooth, and REV to the moon, with no vibration... Mazda says they are still working.. I guess we will see.. But I kinda doubt it. With CAFE shit.. and the Govt preoccupation with hugging trees... I bet they are gone... So sad.
Actually heat is an enemy of turbochargers. Extremely hot exhaust gases will heat incoming air as it passes through the hot compressor and increase intake temperature, which is bad for making power.
it a total myth that the the rotary is a light engine their are standard production car piston engines that are lighter with the same power of an rx8.. and if you start looking at 2 stroke bike engine they have 2/3 more power pr cc and 1/2 the weight..the rotary not even close as the engines with the best power to weight ratio ..i don't know how this myth stated..properly marketing departments
blakeman8192 Heat and volume is what drives the turbo, I guess if it got hot enough what your saying would be true, But most have both oil to lube, and cool, and a engine coolant line into the center cartridge to bring down the heat to the engine coolat temp. The intake temps get plenty hot enough with the heat of comrpession.. Intercooler will help drop that down. Point being that rotarys drive turbos better than other engines..
kens97sto171 Good comments, The Wankel has more waste heat energy in the exhaust stream because its less mechanically efficient so there is more potential heat energy to run the exhaust turbine... of course the ideal operating temperature of the turbine is less than the peak EGT so more fuel enrichment is required... increasing BSFC even further. good for power, but not for overall combined cycle efficiency Increasing manfold boost pressure also increases stress on the the apex seals which tend to flutter and leak at high dynamic compression ratios... not good for longivity on an engine design that already has a very limited service life on average. cheers!
The real doktorbimmer The E shaft spins 270 degrees per phase (intake, compression, power, exhaust), but the port timing is still worked out in 180 degree increments of rotor phasing. The E shaft spins faster, in relation to, the rotor and its 4 "strokes". This is how you can figure that a rotary opens its exhaust "valve" earlier than a typical piston engine. There is no interrupted flow (obstruction--- Valve and stem) in the exhaust port. It is a straight shot. The valves remove alot of heat from a 4 cycle engine through the seat and guides. Only reason.
dokterbimmer For an external applied force, the change in velocity depends on the mass of the object. A force will cause a change in velocity; and likewise, a change in velocity will generate a force. The equation works both ways. The third law states that for every action (force) in nature there is an equal and opposite reaction. In other words, if object A exerts a force on object B, then object B also exerts an equal force on object A. Notice that the forces are exerted on different objects. The third law can be used to explain the generation of lift by a wing and the production of thrust by a jet engine. You can view a short movie of "Orville and Wilbur Wright" explaining how Newton's Laws of Motion described the flight of their aircraft. The movie file can be saved to your computer and viewed as a Podcast on your podcast player.
+SnufflesDominance Piece of shite !!. Concept is all wrong. Horrid sort of stroker. I would be surprised if there was any material on this earth that would stand up the heat generated on the rotor apex seals for very long. The side seals seem to get away with it for longer. These engines by their design and 2 stroke principle have a high fuel consumption, high oil consumption and a high degree of wear to go with it. Useless for general road use. If you want power then don`t fuck around with this crap, get yourself a motor with a good V8 in it for muscle.
+Crobular I 1st - All modern rotary engines (ie anything done in the past 3 decades) are all 4 "stroke" type engine (although is more like 4 phases as it all happens almost at the same time). In 1 rotation the engine fires 3 times as oppose to a piston which does 1 every other. But it does have all 4 phases/strokes. 2nd - The engine on the Mazda 787b won in the 24 hour of Le Mans because of fuel economy and reliability. The only Japanese vehicle ever to do so. 3rd - all the new F1 engines are turbo V6. So the next high performance boost will be all in the V6 engines.
+Crumbly yes, and what load of old bollocks it is. It will never be any good for commuting around and taking the kids to school with it`s enormous thirst for gas and lousy emissions. I drove a saloon once and it went OK but the gas consumption was worse than my XJ8. Not to mention the total loss oil consumption. The whole concept is all wrong for it`s intended use. The specialist one in the video runs misfiring all over the place. If you think I am a prick them please tell me.
You’ve got to love a rotary engine, its so simple but powerful as hell for its size. I can remember getting an RX8 when I was 23 and absolutely loving it, before that little Mazda I had only had boring Renaults but this thing was a different world, it was so sporty, light and it just revved forever!! Yeah fuel wasn’t fantastic at about 20mpg, usually lower for me because I just couldn’t help myself but overall it was a brilliant car, it got me liking Mazda and I would of had another rotary if they did one but the next car was a Mazda 6 2.2 Sport which again was another fantastic car from Mazda, it was a completely different feel obviously but it was good all round, really fast for a diesel, quick uptake off the line for its size, mpg was fantastic I always got 50+ mpg easily, really great features, sensors etc for the cost of the car, more than you would get in a German brand anyway and just a great quality to the materials like leather etc top BOSE system etc I’ll have another Mazda for my next car I think ;)
kamencho1 Poor people don't buy new cars... new cars today typically come now with 100,000 mile powertrain warrantys... something not possible with a Wankel under the hood.Its also very common with proper maintance to see engines last 250,000 miles or more... something not possible with the Wankel either...Its why no one sells a car with a Wankel engine anymore... they are totally and completely obsolete now...
This is my Dad's Dyno, when I was a kid I used to vaporise Gummibears on the exaust manifolds when my Dad was testing. These are only Red hot, they would get White hot after a longer run...
Pascals Law refers to an equivalence of pressure and volume relationship. If you're increasing pressure, volume must decrease to maintain preservation of energy. Take a balloon for instance, if you decrease the size on one side, the opposite side increases to maintain volume relationship. So the argument does not pertain, the principal in essence is correct
Meet Dr. James Lemke - a serial entrepreneur with a history of founding and leading companies to successful exits and a personal passion for science, engineering and education. Dr. Lemke founded Achates Power in 2004 with an idea that would revolutionize the automotive industry by revitalizing the opposed-piston, two-stroke engine. As an influential physicist holding more than 100 patents, Lemke understood that the rapidly increasing shortage of fuel and greater need for emissions reduction meant the world needed a solution. That solution came in a 1930s-era engine architecture that demonstrated great potential, but momentum had dissipated when the tools of the time could not produce an efficient version. Lemke knew the tools and the talent were now available to answer the transportation crisis. Dr. Lemke started Achates Power with a collection of the brightest engineers and scientists with the condition that ideas and discourse flow unabated and the expectation that each fulfill their utmost potential. While amassing top talent in the industry, Lemke’s vision began to manifest results. However, instead of an engine that only moderately answered the need for efficiency, the Achates Power engine realized a more than 30 percent fuel efficiency improvement compared to the industry’s best diesel engines and nearly double the fuel efficiency of a standard gasoline engine at lower emissions levels and at 10 percent lower cost. While Lemke always believed in the engine’s viability, now the results have shown the industry the potential economic savings of trillions of dollars per year on fuel and components, and billions of gallons of fuel saved per year. Please enjoy this biography on Dr. Lemke and the history of Achates Power.
+John Dickens didn't it also have something to do with the thermal imbalance in the engine, poor fuel efficiency, high maintenance, and poor power output compared to other engines? I'm not saying certain advancements haven't been thwarted by major manufacturers, they have been time and again. I'm just saying that in this case there were legitimate reasons for discontinuing use of the rotary engine.
***** Yes, you're probably right. It would have been interesting to see how they sorted all those issues. Unfortunately, the costs associated with going back to the drawing board on the rotary outweighed the time to market on an improved product. So they just allocated those r&d funds to furthering a more promising design. There's no question that the rotary was an ingenious piece of engineering though.
Awesome Dyno run of the 4 rotor. So, this is what? About a 2600cc engine putting out about 700 hp naturally aspirated (all motor)? I know that most builders add rotors to increase displacement but has there ever been a "Big Block" rotary designed with larger scale housings and rotors? I know these engines have amazing output per liter but was wondering what a larger scale one would do. Also, has anyone experimented with direct injection like a lot of production piston engines are going to now?
+manstersr Yep, it does about 700HP naturally aspirated. The later version, used in the 787B could go up to 960HP in qualifying, but was detuned to 700HP for reliability and fuel consumption in the race. Not that reliability was an issue; Mazda's engineers, when disassembling the engine after the race, found such little wear, that they estimated that the engine could've ran for another 24 hours without any issue. As for your question regarding the "Big Block" rotary, I think the current sizes are used because they seem to be the optimal size from both an engineering and reliability standpoint.
I know this is a very old video. But, I've always wondered the same thing. My thoughts are If you take a 12a 1.1 but double it to 2.2 " with bigger rotors and housings", wouldn't that eliminate the twist problem that 4 rotor engines have? I'm no engineer by any stretch but I've always thought about that as well

I'm the first one who asked several questions of you in this latest round of the internet trolling you. And you still haven't responded specifically to those questions.
@Maimo Moline There are home built experimental airplanes that are powered by lawn mower engines too but like the handful of Wankel planes none are FAA certified as airworthy.
Terrible airplane engine: Too many rpm, it would require a reduction drive resulting in more weight, complexity, and maintenance. Terrible economy, more fuel = more weight... or less range = pointless. Apex seal wear results in costly short TBO's Anyway, I could ramble on, but in short... it'd be a shit airplane engine.
The trailing side of the rotary engine's combustion chamber develops a squeeze stream which pushes back the flamefront. With the conventional one or two-spark-plug system and homogenous mixture, this squeeze stream prevents the flame from propagating to the combustion chamber's trailing side in the mid and high engine speed ranges, Mazda engineers described the full process in 'Combustion characteristics of Rotary Engines', K Yamamoto et al., SAE paper 720357. Kawasaki addressed this problem in their US patent nº 3848574. This poor combustion in the trailing side of chamber is one of the reasons why there is more carbon monoxide and unburnt hydrocarbons in a Wankel's exhaust stream. A side-port exhaust, as is used in the Renesis, avoids one of the causes of this because the unburned mixture cannot escape. The Mazda 26B avoided this issue through a 3-spark plug ignition system. (At the Le Mans 24 hour endurance race in 1991 the 26B had significantly lower fuel consumption than the competing reciprocating piston engines. All competitors had the same amount of fuel available due to the Le Mans 24 hour limited fuel quantity rule.)[56] An inventor proposed that a narrow linear opening for spark plugs in the housing, instead of the round hole, would improve volumetric efficiency, fuel economy and emissions; he claims to have proved this by recording a measured reduction in the exhaust gas temperature. As in early reciprocating engines, a lower effective compression ratio is linked to higher exhaust gas temperatures.* *(RUclips: 'Rotary Engine Breakthrough')*

Rotary motor explained...Wankel engines, more commonly known as rotary engines, differ from regular engines as they don’t have a reciprocating piston travelling up and down in a cylinder. Instead a triangular shaped rotor spins inside an hour-glass shaped housing. Valves in the casings allow gases to transfer, similar to a two-stroke, but unlike a reciprocating engine all the parts inside move in the same direction. This means the engine is smooth, compact and capable of delivering a high power-to-weight ratio

blakeman8192 Heat and volume is what drives the turbo, I guess if it got hot enough what your saying would be true, But most have both oil to lube, and cool, and a engine coolant line into the center cartridge to bring down the heat to the engine coolat temp. The intake temps get plenty hot enough with the heat of comrpession.. Intercooler will help drop that down. Point being that rotarys drive turbos better than other engines..
kens97sto171 Good comments, The Wankel has more waste heat energy in the exhaust stream because its less mechanically efficient so there is more potential heat energy to run the exhaust turbine... of course the ideal operating temperature of the turbine is less than the peak EGT so more fuel enrichment is required... increasing BSFC even further. good for power, but not for overall combined cycle efficiency
Increasing manfold boost pressure also increases stress on the the apex seals which tend to flutter and leak at high dynamic compression ratios... not good for longivity on an engine design that already has a very limited service life on average.
cheers!

The E shaft spins 270 degrees per phase (intake, compression, power, exhaust), but the port timing is still worked out in 180 degree increments of rotor phasing. The E shaft spins faster, in relation to, the rotor and its 4 "strokes". This is how you can figure that a rotary opens its exhaust "valve" earlier than a typical piston engine. There is no interrupted flow (obstruction--- Valve and stem) in the exhaust port. It is a straight shot. The valves remove alot of heat from a 4 cycle engine through the seat and guides. Only reason.

For an external applied
force, the change in velocity depends on the mass of the object. A force will
cause a change in velocity; and likewise, a change in velocity will generate
a force. The equation works both ways.
The third law states that for every action (force)
in nature there is an equal and opposite reaction. In other words, if object
A exerts a force on object B, then object B also exerts an equal force on object
A. Notice that the forces are exerted on different objects. The third law can
be used to explain the generation of lift by a wing
and the production of thrust by a jet engine.

+SnufflesDominance Piece of shite !!. Concept is all wrong. Horrid sort of stroker. I would be surprised if there was any material on this earth that would stand up the heat generated on the rotor apex seals for very long. The side seals seem to get away with it for longer. These engines by their design and 2 stroke principle have a high fuel consumption, high oil consumption and a high degree of wear to go with it. Useless for general road use. If you want power then don`t fuck around with this crap, get yourself a motor with a good V8 in it for muscle.
+Crobular lok up the 2jz and rb26 motor, then rethink ur heavy v8
+Crobular I
1st - All modern rotary engines (ie anything done in the past 3 decades) are all 4 "stroke" type engine (although is more like 4 phases as it all happens almost at the same time). In 1 rotation the engine fires 3 times as oppose to a piston which does 1 every other. But it does have all 4 phases/strokes.
2nd - The engine on the Mazda 787b won in the 24 hour of Le Mans because of fuel economy and reliability. The only Japanese vehicle ever to do so.
3rd - all the new F1 engines are turbo V6. So the next high performance boost will be all in the V6 engines.
+Crobular I Mopar
+Crumbly yes, and what load of old bollocks it is. It will never be any good for commuting around and taking the kids to school with it`s enormous thirst for gas and lousy emissions. I drove a saloon once and it went OK but the gas consumption was worse than my XJ8. Not to mention the total loss oil consumption. The whole concept is all wrong for it`s intended use. The specialist one in the video runs misfiring all over the place. If you think I am a prick them please tell me.

That happens if the ignition timing is delayed, it has low thermal efficiency, most of the energy is thrown out at the exhaust.
+Odouls77 Like some early strokers. Unless they were "on the pipe".
I have never seen an exhaust get that hot
You’ve got to love a rotary engine, its so simple but powerful as hell for its size.
I can remember getting an RX8 when I was 23 and absolutely loving it, before that little Mazda I had only had boring Renaults but this thing was a different world, it was so sporty, light and it just revved forever!!
Yeah fuel wasn’t fantastic at about 20mpg, usually lower for me because I just couldn’t help myself but overall it was a brilliant car, it got me liking Mazda and I would of had another rotary if they did one but the next car was a Mazda 6 2.2 Sport which again was another fantastic car from Mazda, it was a completely different feel obviously but it was good all round, really fast for a diesel, quick uptake off the line for its size, mpg was fantastic I always got 50+ mpg easily, really great features, sensors etc for the cost of the car, more than you would get in a German brand anyway and just a great quality to the materials like leather etc top BOSE system etc I’ll have another Mazda for my next car I think ;)
@@footballcoreano bruh, how about trying old BMWs and old mercedes
that exhaust manifold sure got a bit soft there.
Yes, shame to have wasted all that heat ... a nice chunk of good steak or bacon would have done nicely on that!

kamencho1 Poor people don't buy new cars... new cars today typically come now with 100,000 mile powertrain warrantys... something not possible with a Wankel under the hood.Its also very common with proper maintance to see engines last 250,000 miles or more... something not possible with the Wankel either...Its why no one sells a car with a Wankel engine anymore... they are totally and completely obsolete now...

Pascals Law refers to an equivalence of pressure and volume
relationship. If you're increasing pressure, volume must decrease to
maintain preservation of energy. Take a balloon for instance, if you
decrease the size on one side, the opposite side increases to maintain
volume relationship. So the argument does not pertain, the principal in
essence is correct
Meet Dr. James Lemke - a serial entrepreneur with a history of founding and leading companies to successful exits and a personal passion for science, engineering and education. Dr. Lemke founded Achates Power in 2004 with an idea that would revolutionize the automotive industry by revitalizing the opposed-piston, two-stroke engine. As an influential physicist holding more than 100 patents, Lemke understood that the rapidly increasing shortage of fuel and greater need for emissions reduction meant the world needed a solution. That solution came in a 1930s-era engine architecture that demonstrated great potential, but momentum had dissipated when the tools of the time could not produce an efficient version. Lemke knew the tools and the talent were now available to answer the transportation crisis. Dr. Lemke started Achates Power with a collection of the brightest engineers and scientists with the condition that ideas and discourse flow unabated and the expectation that each fulfill their utmost potential. While amassing top talent in the industry, Lemke’s vision began to manifest results. However, instead of an engine that only moderately answered the need for efficiency, the Achates Power engine realized a more than 30 percent fuel efficiency improvement compared to the industry’s best diesel engines and nearly double the fuel efficiency of a standard gasoline engine at lower emissions levels and at 10 percent lower cost. While Lemke always believed in the engine’s viability, now the results have shown the industry the potential economic savings of trillions of dollars per year on fuel and components, and billions of gallons of fuel saved per year. Please enjoy this biography on Dr. Lemke and the history of Achates Power.

+John Dickens didn't it also have something to do with the thermal imbalance in the engine, poor fuel efficiency, high maintenance, and poor power output compared to other engines? I'm not saying certain advancements haven't been thwarted by major manufacturers, they have been time and again. I'm just saying that in this case there were legitimate reasons for discontinuing use of the rotary engine.
*****
Yes, you're probably right. It would have been interesting to see how they sorted all those issues. Unfortunately, the costs associated with going back to the drawing board on the rotary outweighed the time to market on an improved product. So they just allocated those r&d funds to furthering a more promising design. There's no question that the rotary was an ingenious piece of engineering though.
Those are headers, bitch.
+The Gaming Chicken It's the same thing dumb fuck.
Awesome Dyno run of the 4 rotor. So, this is what? About a 2600cc engine putting out about 700 hp naturally aspirated (all motor)? I know that most builders add rotors to increase displacement but has there ever been a "Big Block" rotary designed with larger scale housings and rotors? I know these engines have amazing output per liter but was wondering what a larger scale one would do. Also, has anyone experimented with direct injection like a lot of production piston engines are going to now?
+manstersr Yep, it does about 700HP naturally aspirated. The later version, used in the 787B could go up to 960HP in qualifying, but was detuned to 700HP for reliability and fuel consumption in the race. Not that reliability was an issue; Mazda's engineers, when disassembling the engine after the race, found such little wear, that they estimated that the engine could've ran for another 24 hours without any issue.
As for your question regarding the "Big Block" rotary, I think the current sizes are used because they seem to be the optimal size from both an engineering and reliability standpoint.
I know this is a very old video. But, I've always wondered the same thing. My thoughts are If you take a 12a 1.1 but double it to 2.2 " with bigger rotors and housings", wouldn't that eliminate the twist problem that 4 rotor engines have? I'm no engineer by any stretch but I've always thought about that as well
Awesome!

For a guy who claims to be an engineer, you sure spew a lot of ad-hominem attacks… no one here ever once said any new cars were getting wankel engines. What we are saying is the engine does have merits. Some in the transportation industry like the simplicity, some like the compactness, some like the free revving ability

What could make an incredible airplane engine!
Wankel engines are too unreliable for airplanes.
@Maimo Moline There are home built experimental airplanes that are powered by lawn mower engines too but like the handful of Wankel planes none are FAA certified as airworthy.
@Maimo Moline There are none with a airworthiness certificate... Wankel engines are too unreliable and totally unsuitable for aircraft.
Terrible airplane engine:
Too many rpm, it would require a reduction drive resulting in more weight, complexity, and maintenance.
Terrible economy, more fuel = more weight... or less range = pointless.
Apex seal wear results in costly short TBO's
Anyway, I could ramble on, but in short... it'd be a shit airplane engine.
@@dash8465 That is exactly why not a single aircraft manufacturer sells a plane with a Wankel engine.
Looks like a pulse jet!
The trailing side of the rotary engine's combustion chamber develops a squeeze stream which pushes back the flamefront. With the conventional one or two-spark-plug system and homogenous mixture, this squeeze stream prevents the flame from propagating to the combustion chamber's trailing side in the mid and high engine speed ranges, Mazda engineers described the full process in 'Combustion characteristics of Rotary Engines', K Yamamoto et al., SAE paper 720357. Kawasaki addressed this problem in their US patent nº 3848574. This poor combustion in the trailing side of chamber is one of the reasons why there is more carbon monoxide and unburnt hydrocarbons in a Wankel's exhaust stream. A side-port exhaust, as is used in the Renesis, avoids one of the causes of this because the unburned mixture cannot escape. The Mazda 26B avoided this issue through a 3-spark plug ignition system. (At the Le Mans 24 hour endurance race in 1991 the 26B had significantly lower fuel consumption than the competing reciprocating piston engines. All competitors had the same amount of fuel available due to the Le Mans 24 hour limited fuel quantity rule.)[56] An inventor proposed that a narrow linear opening for spark plugs in the housing, instead of the round hole, would improve volumetric efficiency, fuel economy and emissions; he claims to have proved this by recording a measured reduction in the exhaust gas temperature. As in early reciprocating engines, a lower effective compression ratio is linked to higher exhaust gas temperatures.* *(RUclips: 'Rotary Engine Breakthrough')*

But to answer your question: 2019 at Mazda, you can buy cars with a rotary or Wankel engine, depending on what you prefer to call it. Doesn't matter as they're both the same engine, but ofcourse someone whos a genius on all things rotary like yourself knows that.

Rotary motor explained...Wankel engines, more commonly known as rotary engines, differ from regular engines as they don’t have a reciprocating piston travelling up and down in a cylinder. Instead a triangular shaped rotor spins inside an hour-glass shaped housing. Valves in the casings allow gases to transfer, similar to a two-stroke, but unlike a reciprocating engine all the parts inside move in the same direction. This means the engine is smooth, compact and capable of delivering a high power-to-weight ratio
