We even produced some high speed footage of auto-ignition in a combustion chamber by using a quartz window back in the early 00's. High speed cameras have come a long way since then. I think the cameras we were using were something like 180px horizontal resolution, haha. It's super cool to see the flame propagation through air with such detail! Very cool to see this being covered!

Gasoline is INCREDIBLY volatile. It'd start to evaporate on the way down and the fumes would easily catch on fire. The liquid isn't ever what ignites. It's the vapor coming off of it.

The BEST case open air scenario is a deep container with no air flow over it. Gas vapor is heavier than air so it'll mostly sink and should somewhat stay contained without airflow disturbing it and allowing more to evaporate. Still, gasoline is probably the most volatile liquid I know of other than maybe alcohol. Any gasoline left in open air isn't gonna be great news. But yes, the smaller the surface area, the slower it'll evaporate. So laminar would definitely be best

Many years later after discovering this channel, it still makes me smile and laugh. And of course I ALWAYS learn something. A true gem in the youtube world.

12:22 - you talk about the radial boundary being based on the stoichiometry, which is a factor, but also consider that there is flow happening! As the stream pushes outwards, it is carrying fuel mass and air (vapors) outwards, which continues to push the flame front in addition to the AF gradient. Super awesome stuff to think about! Thanks for this video!!

As a young truck mechanic, one of my jobs were to test injectors, and a trick the old fellas gave me was to make pressure peaks while pumping to "clean" the injectors, quite often you could save one with a bad pattern by cycling it with the tester. Also, the needle from a scrapped injector is a really great centerpunch, it is really hard and with a sharp tip, we always used them when centerpunching broken bolts that we drilled out

What a wonderful world it would be if more people shared your enthusiasm for science! Very inspiring! Thanks.

I really enjoyed this video. Since you’re planning to explore other methods of fuel injection, I think it would be extremely cool to see a comparison between a typical car’s fuel injectors (~350cc/min) and a big methanol fuel injector, like top fuel/high end drag racing uses (the biggest individual injectors I’m aware of are advertised as being able to flow over 11,000 cc/min, or 1050 pounds per hour of fuel).

@@DavidBergman1776 So, you're saying that just any carb would work then? Because a 40mm Mikuni carb works just as well on a 4 stroke motorcycle as it does on a 2 stroke quad. In some cases, only a few adjustments need to be made to the needle position and idle jet...there is no physical difference between them. I'm still fascinated that the tiny carbs on weedeaters and chainsaws work as well as they do, even though they're so much more simplified in their operation compared to something found on a dirtbike or a car...they're still doing the same exact thing with a fraction of the complexity at whatever angle you want to run them at. What you might be more interested in is the old pressure carbs that they used on WWII aircraft, those were extremely complex with a multitude of passageways, bellows, chambers, and various metering systems all working as one to deliver the right amount of fuel at the right time. They're complex enough that only one or two companies in the US are capable of properly overhauling them these days.

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.

loved all those shots of the fireballs. so sick

This has had some amazing slow motion, but that single nozzle injector at the end is the coolest thing you have ever recorded (IMHO). So Beautiful. Thanks.

I love how excited you get when you are learning something. And you are a VERY smart man so its probably not super easy for you to get really excited learn something completely new (meaning, you probably know or have a guess about how most mechanical things work).

Fire! Always good for videos, and adding old tractors makes this one top notch.

Love your "childish" fascination and enthusiasm, it's infectious. Makes me excited to see and learn more. Thank you. Next thought in my mind - is the effect a confined space and pressure have.

Though your videos are extremely interesting and informative, it's your attitude and warmth that keeps me coming back for more. You're an inspiration for us all to be better people. Thanks!

What really awesome was that Luke was talking about the same stuff in the Saturn 5 video. It’s very cool how engineering is all connected. From spaceships to tractors!

The last few clips of the single spray point nozzle look amazing

Well done maestro !! I enjoyed it !!

You should check out mechanical fuel injection pumps, they are amazing piece of machinery, almost like a separate little engine.

Good old Bosch VE and Cummins P pump.

i just love the way slomo gives you a look at the finer details of stuff that we see around us everyday, its like looking at things under a microscope, amazing! keep up the great work

I'm so glad I clicked on this video. Watching the fire in slow mo was so worth it. Thanks for doing this.

This is awesome, love seeing a company step up to the plate to keep old machines running.

I am so glad I found this channel a few years ago. The range of subjects, the work put into each video, is always top level. I have always been curious and took a lot of stuff apart over the years to satisfy that curiousity. Possibly one of the reasons I became a professional car mechanic. Learn something new almost everyday.

As you were stating in the video about boundary conditions, it brings to question as to how much that changes with compression and differing methods of injection. Fascinating content as always!

Specifically in a diesel, the air temperature generated from compression should reach well over 400*F. This does two things. Diesel fuel is heavy and oily, which makes it hard to atomize. Part of that atomization happens due to injector orfice geometry, but the heat inside the cylinder helps to further atomize and mix the fuel with air. Second, the air is hot enough to cause auto-ignition of that atomized fuel. This is why todays diesels operate in excess of 30,000psi of fuel pressure to guarantee the best possible atomization and shorten the time for auto-ignition to occur

Something about, the slow motion tracking and video of, the flames feels so ethereal!
