    My friend owns an RX7 and knows a guy who owned an RX7 FC. The guy ended up getting a turbo for it and cranked the boost up to 24 PSI which was higher than the maximum of 23 PSI. The same guy got into a drag race with a Camaro. The FC smoked the Camaro but at the end of the drag race he heard a shredding sound inside his engine. The car could barely move after that so he ended up taking apart the engine to diagnose the problem. Turns out because he cranked the boost up so high the apex seal was blown right out of its socket as it couldn't handle the pressure. The rotor then dragged the apex seal around the entire housing which shredded the interior completely. He ended up replacing the rotor and still has the one with the shred marks and gashes sitting on his desk at home.

    I just love the look of the RX-7, one of the few modern "rounded" cars that looks good (plus it has pop-up headlights!) but if I ever bought one I'd probably get a less oil burning engine put in. After the original one fails of course, no point in removing a perfectly good engine!

      One works and the other doesn't, anti-matter is just matter with inverted charges, the only special thing about is that it converts itself and matter into pure gamma-rays if it comes into contact with matter.
      If you somehow were to be able to get a really fast spinning black hole than (theoretically) close to its singularity space-time would bend so much you'd get a closed time-like curve and do things like travel back in time or defy space as we know it.

      Crazy_Borg rotaries are actually really simple to work on. They're much easier than most engines, they just have this stigma around them because most mechanics have no clue how to work with them. Usually only rotary owners know how to work with 'em. If you meet a regular mechanic that knows how to work on them, I can guarantee you that they owned a rotary in their life for long enough to need to replace some stuff

      Fun fact, the Rotary has a true displacement of 3.9L. It makes just as much horsepower as a 2006-2012 Chevrolet Impala equipped with the 3900 V6, which is not impressive at all.

      *The Wankel was plagued by very poor torque characteristics due to the inherently poor mechanical conversion rate, they are simply very inefficient in converting the heat and pressure of combustion into usable torque.*

    Also may I add, rotary engines have poor breaking performance compared to cylinder engines, requiring a different style to driving.

  • @NateRist
    @NateRist 6 років тому +313

    a few things wrong with this:
    1: Rotary engines are very easy to maintain, there is absolutely nothing hard about it at all unless being consistent with standard basic maintenance and adding a bit of oil to your fuel is somehow hard for you then that's on you.
    2: The only unreliable thing about a rotary engine is the owner, if the engine fails on you 9.9/10 times it's something that you did (or didn't do) and not the engine's fault. Or may even have been built poorly and/or incorrectly (it happens just like it does with piston engines too). Rotaries do hate boost though, so I won't fault anyone for that (wanna be fast? it won't be reliable. Wanna be reliable? it won't be fast - can be kinda quick though lol). Also something to note is that the old (pre-1986) carbureted rotaries were very reliable, there are still plenty of them running today with up to 400,000 original miles on them. The 13B in my daily driver SA22C is over 40 years old, street ported, makes fairy decent power and torque and came from a junkyard as is and I've put over 20,000 miles on it with no engine related problems at all in the last year that I've owned it (actual car or engine mileage is unknown, ODO is only 5 digits and engine was built in the early 80s and that's all I know). My last RX-7 also had over 261,000 miles on it when it was totaled in an accident and ran great too, so this "unreliable" stigma that rotaries have isn't very well deserved, it's more that it's just not for everyone
    3: You can use rotaries in many different applications including aircraft, boating, sandrails hell even RC cars too (and yes there are RC cars with Wankel rotary engines small enough to fit in the palm of your hand and make about 1ish HP lol)
    Basically what I'm saying is that rotaries are awesome wonderful little engines that deserve more credit that many people aren't very willing to give them. they're simple, easy to maintain, easy to understand and are just plain fun because you can beat the dogshit out of them as much as you want whenever you please (granted that your engine is at operating temp of course). But as I've stated, they're just not for everyone just like pistons aren't for me and that's okay:)

    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

    In 1977 My first car was a Mazda R 100. I was warned that they blew up and it did. The seals on the water jacket went, similar to a blown head gasket. My dad took me down to Mazda, we got a rebuild kit, and the best engine manual I’ve ever seen. Step-by-step instructions with pictures. from disconnecting the battery removal disassembly reassembly and reinstall. The overheating Warped the aluminum rotor housings. They were very expensive so my dad had me hand lap them on a lapping table. Getting them down to the 3000’s tolerance they needed. I assembled the motor. My dad tried turning the motor over by hand before we put the motor back in the car. The motor wouldn’t turn, he determined that we had lapped the rotor housings down but not the apex seals. He machined them down, and I reassembled it put the motor in and it ran beautifully. The Wankel engine is a very simple design with few moving parts which is great. I sold the car almost immediately so I could buy the car I really wanted which was a 1968 Plymouth Road Runner four speed with a Posi rear end. The Wankle engine is revolutionary, but you just can’t beat the awesome sound of Detroit iron. It was all a great learning experience though. I was really blessed to have such a smart dad willing to help me. I still have a black-and-white photo of me holding one of the rotors. Over the years I had three Road runners. I still have my 73 barracuda 340 with a pistol grip four speed which I bought in 1975. Sorry Mr. Wankel but Chrysler really is the king of cool.

    1.4 and 2 litres is a pretty narrow range. My first fiesta was 957cc and my current car is 2.4l, both inline fours

    You missed that rotary motors are always in a power cycle so they get hot.

      My friend owns an RX7 and knows a guy who owned an RX7 FC. The guy ended up getting a turbo for it and cranked the boost up to 24 PSI which was higher than the maximum of 23 PSI. The same guy got into a drag race with a Camaro. The FC smoked the Camaro but at the end of the drag race he heard a shredding sound inside his engine. The car could barely move after that so he ended up taking apart the engine to diagnose the problem. Turns out because he cranked the boost up so high the apex seal was blown right out of its socket as it couldn't handle the pressure. The rotor then dragged the apex seal around the entire housing which shredded the interior completely. He ended up replacing the rotor and still has the one with the shred marks and gashes sitting on his desk at home.

    The only advantage that the rotary engine has is that you can add "banks" (more rotors) to increase displacement without taking up much space. Thus a "4 cylinder" equivalent can become a "6 cylinder" by adding a single rotor to the mix.

    When the rotor goes around the shaft in the demo I see teeth on teeth action, is that your rev or your grinding bud?

      The gears maintain the very important 3:1 ratio between the crankshaft and the triangular piston(rotor)
