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
