給你們看看今天的節目

Briggs & Stratton engine.

L型汽缸頭的百力通(B&S)引擎

with a transparent head that we build a few months back.

安裝我們花了幾個月的時間精心製造的透明缸頭

Good job Maddie.

梅狄做的好

Wow it looks great.

哇！看起來很不錯

Yes.

是

How old are you Maddy.

梅狄妳幾歲呀？

兩歲

One two.

一、二

2 years old?.

兩歲？

Thank you.

謝謝妳

Your turn.

換你了

My turn?.

換我嗎？

Here you go thank you.

-給你 -謝謝妳

For an ultra-high speed shoot we were doing for vision research.

我們的超高速攝影視覺研究

we were showing the combustion process from rich to lean.

可以看到火焰由生到滅的整個燃燒過程

In ultra-high speed or Ultra slow motion.

超高速而且超慢動作

And the other day this video showed up in my subscriptions feed of these guys.

以前我在訂閱頻道裡看了這支影片

We're here at our buddy John's and he's uncovering the Oakland.

「這是我麻吉John，他正掀開一輛奧克蘭」

That built something similar to the engine that I built that I just showed you.

那輛車的引擎很像我身後的引擎

Oh no we broke our flywheel that's it for that.

「糟了，我們弄壞飛輪了」 「就這完意兒」

And it reminded me of those clips.

這讓我想起這些影片

Now we're going to burn a few different types of fuel.

現在我們要燒幾種不同的燃料

The first one is going to be straight gasoline.

第一種就是汽油

The second is going to be rubbing alcohol which a friend of mine Chris suggested.

第二種燃料 吾友克里斯建議我用酒精

I really want to see the unburned exhaust gases.

我真的很想看到未燃燒的氣體從

Exiting the exhaust port.

排氣管噴火

So I'm going to go ahead and remove the muffler completely.

所以我要把排氣管拆掉

Get some earplugs.

準備好耳塞

And fire this thing back up.

讓他燒吧

Ready to rock and roll.

開始搖滾

So that's what the alcohol looks like.

這就是酒精的情況

And after looking at the slow-motion footage.

看完這些慢動作鏡頭

Seems like the alcohol kind of rinsed out the cylinder.

酒精似乎把汽缸洗乾淨了

And cleaned up some of the soot from the gasoline.

清除了一些汽油的煤煙

And interestingly enough.

很有趣的一點

It was really weird.

真的很奇怪

It was like the cylinder was full of liquid.

看起來汽缸充滿液體

It wasn't even vaporized.

甚至沒有汽化

The spark was still igniting it.

但是火星塞卻可以點燃

Enough to push the Piston down and run the engine.

足以推動活塞運轉引擎

So it was kind of interesting.

真的很有趣

Not for this one I'm actually going to put some safety goggles on.

現在我要帶上護目鏡

Because I've had some bad past experiences with acetylene.

因為我對乙炔有點心理陰影

Alright so what I'm going to do is I'm going to start it up on the alcohol.

好，接著我要用酒精發動引擎

And then add the acetylene.

然後加入乙炔

Which is going to be this one right here.

就放在這裡

Here it goes.

開始囉

That was the coolest thing ever.

真是酷斃了

So I'm going to do that one more time.

所以我要再做一次

But this time.

但是這次

I'm going to turn the acetylene all the way up.

我要把乙炔開到最大

Full open.

火力全開

Because there's so much soot coming out of there.

這會產生很多煤煙

But I think we're still going to be able to see it.

但是我覺得仍然可以看得到

So let's see that one more time With the high speed camera.

再來看一次高速攝影吧

With the acetylene a hundred percent wide open and almost no alcohol.

這次要把乙炔開到最大 幾乎不用酒精

Here it goes.

來囉！

Whoa what happened there let's try that one more time.

噢！怎麼回事，再來試一次

But that put put that out.

把火滅掉

Okay here it goes one more time.

好了，再來試一次

Well it looks like we overdid it on the acetylene a little bit.

我們好像操過頭了

But props out to Kevin from the backyard scientist for suggesting the acetylene.

是後院科學家的凱文建議用乙炔的

Last because now the head seems like it's completely unusable.

現在汽缸頭幾乎不能用了

I'm really curious to see if this engine will actually run on tequila.

我還是很好奇把龍舌蘭酒用在這引擎上會有什麼效果

That's about it well that was a lot of fun and I hope you enjoyed that episode.

以上就是本期節目的全部內容 希望你們喜歡

And the most important thing to me is that you watch and enjoy our videos.

對我最重要的就是你們喜歡、享受我們影片

I know the equipment that we use is out of the reach of most of us.

我知道這些攝影器材一般人很難取得

But the ideas are not.

但是好想法人人有

So if you have any ideas that you want to see come to life.

如果你有任何高速攝影的構想

Just let us know.

讓我們知道

let us know in the comments or send us a message.

請在影片下方留言或給我們私訊

And as usual.

很平常的

Tell us what you think in the comments below.

在影片下方告訴我們你們的想法

Don't forget to like share and subscribe.

而且不要忘記分享與訂閱

Oh and also.

噢對了

Let me know if you want to see this engine run on tequila.

如果你還想看這引擎用龍舌蘭酒的話 請讓我知道

And I'll try it out I don't know if it's worth it.

我會想辦法 但是我不知道值不值得

Because the alcohol was kind of.

因為酒精看起來實在很像

Yeah I was kind of like looked like the inside of a washing machine.

看起來實在很像洗衣機裡面的樣子

But I will try it if you guys want to see me try it.

但是如果有人想看的話我會嘗試

So let us know.

所以讓我們知道

Until next time adios

我們下次見 再見(西語)
