See Through Engine – 4K Slow Motion Visible Combustion ( S1 • E1 )

Welcome to Warped perception. and I’m just going to jump right into it and
show you what we got. we have this L head Briggs & Stratton engine. with a transparent head that we build a few
months back. Good job Maddie. Wow it looks great. Yes. How old are you Maddy. Two. One two. 2 years old?. Thank you. Your turn. My turn?. Here you go thank you. For an ultra-high speed shoot we were doing
for vision research. we were showing the combustion process from
rich to lean. In ultra-high speed or Ultra slow motion. And the other day this video showed up in
my subscriptions feed of these guys. We’re here at our buddy John’s and he’s uncovering
the Oakland. That built something similar to the engine
that I built that I just showed you. Oh no we broke our flywheel that’s it for
that. And it reminded me of those clips. Now we’re going to burn a few different types
of fuel. The first one is going to be straight gasoline. The second is going to be rubbing alcohol
which a friend of mine Chris suggested. I really want to see the unburned exhaust
gases. Exiting the exhaust port. So I’m going to go ahead and remove the muffler
completely. Get some earplugs. And fire this thing back up. Ready to rock and roll. So that’s what the alcohol looks like. And after looking at the slow-motion footage. Seems like the alcohol kind of rinsed out
the cylinder. And cleaned up some of the soot from the gasoline. And interestingly enough. It was really weird. It was like the cylinder was full of liquid. It wasn’t even vaporized. The spark was still igniting it. Enough to push the Piston down and run the
engine. So it was kind of interesting. Not for this one I’m actually going to put
some safety goggles on. Because I’ve had some bad past experiences
with acetylene. Alright so what I’m going to do is I’m going
to start it up on the alcohol. And then add the acetylene. Which is going to be this one right here. Here it goes. That was the coolest thing ever. So I’m going to do that one more time. But this time. I’m going to turn the acetylene all the way
up. Full open. Because there’s so much soot coming out of
there. But I think we’re still going to be able to
see it. So let’s see that one more time With the high
speed camera. With the acetylene a hundred percent wide
open and almost no alcohol. Here it goes. Whoa what happened there let’s try that one
more time. But that put put that out. Okay here it goes one more time. Well it looks like we overdid it on the acetylene
a little bit. But props out to Kevin from the backyard scientist
for suggesting the acetylene. Last because now the head seems like it’s
completely unusable. I’m really curious to see if this engine will
actually run on tequila. That’s about it well that was a lot of fun
and I hope you enjoyed that episode. And the most important thing to me is that
you watch and enjoy our videos. I know the equipment that we use is out of
the reach of most of us. But the ideas are not. So if you have any ideas that you want to
see come to life. Just let us know. let us know in the comments or send us a message. And as usual. Tell us what you think in the comments below. Don’t forget to like share and subscribe. Oh and also. Let me know if you want to see this engine
run on tequila. And I’ll try it out I don’t know if it’s worth
it. Because the alcohol was kind of. Yeah I was kind of like looked like the inside
of a washing machine. But I will try it if you guys want to see
me try it. So let us know. Until next time adios

    I'm so supprised plexiglass can take the pressure. Very interesting. I'd love to see an entire crank case made of plexiglass with a plexiglass cylinder head.

    The Alcohol you used is 91% so you had 9% water which is quite a bit. Ethanol fuel is 99.9% Alcohol. Denatured Alcohol found at hardware stores is also a lot closer to 100% than the 91% stuff. Also Even the 91% stuff would run massively better if metered by the carb instead of pored in. your running super rich. very fun to watch!

    There is a spark after exhaust venting? I though only every 2nd stroke needs that … interesting. 
    Maybe it is easier to build it like this, having a spark before every downward motion.

    When you are going to be experimenting with fuels that you have little or no experience with,wear your safety glasses….while standing behind a safety wall.

    I’d like to see the engine run on all the bloviating hot air spewed by our congressional politicians! Perpetual motion! Enough energy to fuel a large city!

    People take for granted internal combustion engines. Not me. I've been in awe of them for 45 years and still am. They are one of the most incredible, almost magical inventions ever devised. That you can harness and control explosions and channel that energy to propel vehicles is amazing. The force of the combustion just to drive the piston down the cylinder is amazing enough but then when you think there still has to be enough residual energy for the piston to turn a crankshaft, which in turn turns the driveshaft, which in turn still has enough force to turn the vehicle wheels propelling a vehicle just boggles the imagination. Then add on top of all this the durability and reliability of internal combustion engines, especially considering they hold together under such stress from the non-stop controlled explosions and you have for me a head-shaking miracle.

    I'm a small engine mechanic and never in my 5 years of working on these have I or has any mechanic actually gotten to see what he's really fixing and what's really going on in those chambers until now. This is amazing.

    That was GREAT! Cool watching the flame front travel. The alcohol would need to be run through the gas tank so carb CAN deliver it through its circuits to atomize it. It looked very flooded with too much when it was poured directly in. However bigger jets may be needed to run on alcohol. Excellent!

    i graduated in bocconi with 100..i m american. if you know the mechanic you know that is overrated. no need to burn corpses found in underland as oil. use almost perpetual move ,patent 1989 / zicchio
