Why Fuel Injectors are AWESOME (28,000 fps Slow Mo) Part 1 - Smarter Every Day 281

I wonder if they tried aiming the streams of fuel at each other like they do with injector plates on rocket engines.

😁😁😁😁😁

I’ve ordered multiple times from across Creek Tractor for my ‘53 Ford Jubilee. Great company!

the single port just reminds me of a flame thrower

👍

There is nothing crude about the word, nipple.

So Beautiful! Another idea added.

Brings back memories back in '98 of doing simulations to match an actual diesel injector. We had imagery of flow inside an transparent injector, and had cool atomisation images. Also saw how cavitation led to better atomisation, up to a point.

Good old right to repair <3

I worked on marine diesel engines. When testing injectors,you could place a sheet of paper in front of the spray and it would pass through the paper without damaging it. Please be very careful when testing injectors. That same spray will pass through your skin and likely kill you.

Hello! Hello friend! I am a Chinese manufacturer, and we are a professional manufacturer of fuel injectors. The fuel injector model you need is priced between $100 and $300. I hope this magical fuel injector can bring us more beautiful communication, which is also quite a good thing for you! Wishing you happiness every day!

If you haven’t learned it yourself already, the injector names your looking for are pintle type which is the style with 4+ holes pointing perpendicular to the nozzle, this type is used in direct injected diesels. The other style is hole type with just single hole pointing straight out, this style is used in semi direct injected diesels.

Dear Destin

there hasn´t yet been a single video produced by you, that I would have regretted watching.
Thanks for the good work!

One question I have about those injectors: Could you quantify, how much fuel (either in cm³ or in grams) gets out with one plunge of the fuel injector tester?

Take care,

greetings from Germany

Thank you for the beautiful work.

The actual application of a diesel injector in cylinder is even more complex. Because the fuel spray must penetrate(the correct distance into the cylinder) the very dense hot air before auto ignition and also must not overshoot it. An in cylinder view would be very telling for you once seen. However there is an awful lot of scientific papers published on fuel diffusion and penetration rates out there if youre interested in further reading

Good atomization of the fuel is essential to efficient combustion

Fuel evaporation point. Diesel can put out a fire. It's not a good idea but it can. The reason is there is a "Flashpoint" and a Fire point" when in contact with air. Neither can happen in a vacuum. But the odd thing is these point for fuel are not a set point. It depends on a lot of factors like humidity, altitude, surrounding temperature and surface contact. Example for contact, if you open a can of soda the contact is contained to the open area and only spits out of that location, but if you pour it on a table the whole thing spits because the bubbles rise to the surface, and then burst breaking the liquid's surface tension. Then if you toss that into the air, each droplet is surrounded.

Hi
Great vidéo.
Thanks.
What's title of Book mechanic ?

Huntsville Fire Chief: so, Mr. Destin, can you explain how the fire started?

Destin: "uh, er, uh ah uhhhhh. Do you know how cool fuel injectors are? Let me show you and we can get smarter every day together!"

Where is the 2nd part? :))

You've got this fetish with the made in america sticker. Why is that?

You really need to go into how different injectors work. Gasoline injectors run around 80-100 PSI and are simple solenoid valves. Old style Diesel injectors are around 3000 PSI and are much more complicated internally. Modern common rail Diesels run around 30,000 PSI and are on another level again.

Destin on the bullet collision video: I don't want to make anything sensational and click baity.
Also Destin: hand firing fuel air mist coming out of injectors.

The single hole injector is called a pintail injector. It's used in indirect injector systems. The injector with a number of holes is called a multi point injector. It is used in direct injection systems. Port injection systems are usually for petrol systems. Just found your channel. Keep up the good work.

You gotta have spark? Uh, no you don't. Diesel is not a spark system.

doesn’t the word “red neck” have negative connotations? (im not english native)

Awesome vid, but your accent also changes when you're on you own and when you're with your friend
I figure that's probably an involuntary thing eh?

My brain matter increased by a few millimeters

Everyone thinks a 12 year old kid doesn't like learning about motives but I love it

amazing ,I love ENGINE

I'm from Vietnam and I like your video

My dad took a picture with you in a party bus 🚌 he is a

Amazing efforts by you!!

can i say friggen awesome?

Admittedly, I’m a bit stoned. But that slo mo/music portion brought me to the ninth level of nirvana. I’m on another plane after seeing that majestic display. Stunned.

I feel like such an idiot watching this guy.

Dustin, have you ever wondered how a tire balancer works? If you have I would love to see your take of a video exploring the mechanics of one! Keep up the great work!

Thanks

I can’t stop noticing that when he’s talking with southerners, he has the strongest southern accent. With narration, he sounds like he’s from Connecticut.

boundary condition 😰 PDE😱

Нет слов, просто потрясающе

WHAT WERE THE TWO BOOKS YOU USED ?

Bad pattern injectors also wash the oil off the cylinder wall, damaging it.

Good music choice for the ball of fire towards the end!👍😎

Great video, thank you!
