See Thru Rotary Engine in Slow Motion – (Wankel Engine) 4K

Welcome back to Warped Perception. This is one of the most anticipated. And exciting episodes that we have filmed
to date. The see-through rotary engine. This Is episode 1 of the see-through rotary
series. The purpose of this episode. Is to introduce you to what. The Wankel rotary engine is. And show you how it works. Before moving on to the more complex rotary
designs. That I’m going to feature in upcoming episodes. If you don’t really know what the rotary engine
is. The Wankel rotary engine. Is most well known for being used. In the Mazda RX7. RX8. As well as a more Antiquated Mazda RX vehicles. It has quite a huge and dedicated following. Amongst many groups of Automotive enthusiasts
around the world. the Wankel rotary engine has also been used. In various aircraft And helicopter applications. Snowmobiles. Motorcycles. And all sorts of stuff. I brought in a friend of mine Alex. From the YouTube channel legit streetcars. To give us his Automotive opinion on the Rotary. Since he is neck-deep in the automotive world. And this is what he had to say. The rotary engine is an internal combustion
engine. Accomplishing the same task as a piston engine. But using a different process. The main difference between a rotary and a
piston engine. Is that the rotary engine doesn’t need to
convert the up and down. Reciprocating motion of the Pistons into a
rotational Force. The main advantage of the rotary engine. Is how much power it can make for its size. Take for example the latest Mazda RX-8. It was only a 1.3 liter. But it made 232 horsepower. And we’re not just talking displacement here. We are talking physical size of the engine. These engines are very small compared to a
typical four-cylinder. And this is how the engine looks that I’m
going to use for this episode. This is a Wankel rotary model aircraft engine. It’s really simple which is why I chose to
use it. And this is the engine with the front taken
apart so we can see inside. This is the simplest Wankel rotary engine
that I know of. This has no ignition. No cooling passages it’s air-cooled. But the principle Remains the Same. If we take a look at the components here we
can see that. There are two main moving components which
is the rotor. That triangular shape thing. And there is The Eccentric shaft. Which is the crankshaft equivalent in a piston
engine. Apart from that we have the rotor housing
right here. And in this case a glow plug. Carburetor and the exhaust Port right here. And if we spend this and the direction of
operation. It pulls the air-fuel mixture in through the
carburetor. Compresses it. It gets ignited. Then we have the power stroke Which pushes
that rotor. Then we have the exhaust stroke. Which is kind of combined with the power stroke. We can see there’s only a couple of moving
components inside this engine. In comparison to the piston engine. Where we have a piston. Valve’s. Crankshaft. Connecting rod. Camshaft, valve lifters, valve springs and
other moving parts. And there’s a couple more complex designs. But this is the one that I’m going to use
to show you the basic principle. Now first I’m going to start this up. To show you just how crazy this little engine
sounds. Now that you’ve seen the engine run on the
bench. It’s time for me to get to work and build
a functional. See Through Wankel rotary engine. Okay so this is where I’m at. I have my see-through rotary engine built
ready to start for the first time. So let’s get this thing started up so we can
see what the inside of a rotary engine looks like while it’s running. Wow that was super cool, I shut it off before
anything happened. Let’s take a look at the high-speed footage and see what is going on inside that combustion chamber. That was pretty cool but it was kind of hard
to see the combustion cycle. So for this next run I painted the propeller
nut and the bracket black. So we don’t have any distractions and hopefully
we can see it a little bit better. Now that looked pretty cool but it was kind
of hard to see the combustion process. So I’m going to run this engine again. But this time I’m going to lace the intake
air with pure acetylene gas. This should beautify the combustion process
and give us a really nice light show. The engine didn’t start here but. This is a good example of how the combustion
pressure. pushes that rotor and creates rotational Force. I could swear that happened in another see-through
Engine episode. I’m going to try it with the torch a little
bit closer and see what happens. I don’t think there’s engine is going to start
right up while injecting acetylene. I’m going to get it started on Nitro first. And then open the acetylene. I hope that I made that simple enough for
everybody to understand, but still entertaining enough for those who already know how it works. That concludes this episode of the see-through
rotary series. I thought that was pretty amazing that we
were able to see inside the rotary engine as it’s running. And I figured this was a great opportunity
to show everybody. Mainly how the combustion process works in
the Wankel rotary engine. That’s mainly what I was focused on here. And again This Is episode 1 of the series. I’m not going to tell you which rotary I’m
going to feature next. But make sure you subscribe so you get notified. So that’s about it let me know what you think
in the comments below. Are you still here?. Well if you got this far you’re all the way
at the end of the video. And I figured I would share a fun fact with
you. That last scene of the see-through rotary
burning acetylene. Took 226 takes. I literally just finished shooting that. My hands have blisters. From pulling this string over and over and
over again. I changed the string about 10 times. Finally I got it to start and I got the mixture
just perfect. And I guess that’s what you call dedication. Because I think it was worth it. Yeah I’ve never seen a see-through rotary
run before. And I’ve never seen a rotary burn acetylene. See you in the next episode. I can’t wait to do the next rotary episode. See you guys next time.

  1. I swear, I just noticed this today, but how is it that no matter what neighborhood you live in chicago, everyone has the same style garage door? “ Yeah can i order flat panels”? “NO! YOU GET SQUARES!!!”

  2. Drove a 1981 13B RX-7 for years, maintenance was never ending. But the power was insane with it's 4 barrel V8 sized carb it had power in-between a V6 and V8 and the throttle response was awesome. Until it blew a seal and needed to go into the shop again. Which was funny because when the seal blew we called it the bat mobile since it had a cloud of smoke behind it for a mile. I stole it from my mom when I was 15 and took my friends on joy rides in it and LIT the tires up and did donuts. My friends Honda couldn't even burn out, and this RX-7 was turning the tires into multon rubber… Oh the good ol days.

  3. I know how engines work and even the totally enginge. But seeing it gives you the ability to envision it and think of new ideas. Great videos sir

  4. Loves me some Wankel engine!
    Now here's what would be the ultimate! Wrap your brain around this: A Wankel/Stirling engine!

  5. Inefficiency is another word for rotary engine. Maybe a second spark plug could ignite the after burn. Has there been any improvements in efficiency?

  6. I've got one of these bastards in my left knee. As a consequence my left leg is far more powerful than my right, which is why I'm always walking in circles. Clockwise.

  7. A reciprocating engine wastes so much energy in trying to start and stop cycle of each piston and puts so much load on each component, why does it even exists?

  8. Mr. Wankel would have been proud, nice demonstration.
    Yea, those RXs get bad gas mileage but the Wankels have a massive power to weight ratio and a power band that just doesn't quit!

  9. I mean, maybe the fuel isn't the right one? Rotary engines rely on high pressure and condensation, so what if we use a fuel that works in that condition? Like propane?

    Somebody should give this a try.

  10. I sometimes stream on TWITCH From Behind the scenes give a follow if you're on twitch.

  11. That was absolutely amazing to see that engine in action! I always wondered how the heck one of these rotary engines actually works. Thanks so much for sharing this! Very informative!

  12. Great video! Always been a fan of the rotary engine despite its problems. Pretty sure the car industry could have solved the problems had it wanted to. Too many piston head engineers.

  13. I heard these engines were not reliable, will break down easier and faster because it has more moving parts than your conventional engine with pistons and valves

  14. Wankels…
    Inefficient by design, apex seals wear out too fast, housing plates get worn. Horrible bloody engines, but every irritating rebuild is rewarded by THAT SOUND!

  15. Thanks for doing this, super interesting! As a kid, my older cousin had a RX-7 that I always admired so much. I never fully understood the rotary engine until now, and see why the seal was so important and a fail point on the Mazda. Great video! New subscriber.

  16. Extremely cool to see this. Well done! Now I don't understand my brothers obsession with his Rx7 's engine. I can see why he seemed to always have it disassembled on a work bench….the design looks like it cant handle abuse.

  17. That's why they shoot flames so easy, I got a friend who owned a RX8 staright piped and nothing else and shoots flames with ease, the un-burnt fuel reaches the hot exhaust and ignites, but for real they are unreliable, he only owned the car for 4 weeks before he sold it since there was so much wrong with it
