The slow motion of the single port injector reminds me of fire breathers. They're doing the same basic thing, spraying the fuel until it atomizes enough to get to the right fuel/air mixture and ignites.
i hope you plan on making another video on the different type of fuel injectors… like from the books you showed us, how diesel compression was different than others.
I just want to say thank you, Destin, and everyone who supports this channel financially. I don't have the extra money to help out, but the attention to extraneous detail is very much appreciated in a world that seems increasingly like everything is turning to easily digestible, CliffsNotes-style explanations. From the topics themselves, to Destin going to farms and such and getting his hands dirty to give us simulated hands-on experience, to the videos of the complexities of the space flight equipment that I'll never use, lol, this channel is a shining city upon a hill. Keep up the great work, and good luck!
Re: #3 - I'm subscribed, but somehow the KZhead algorithm changed my notifications from "all" to "personalized" and I didn't get an alert for this video. Fortunately, the email list came through!
Maybe your hair is too short. :P
It's so hard to explain how fuel is delivered to a vehicle if somebody has never seen it actually happen. This is literally the best showcase of how fuel injectors work. Amazing job. as always!
It's even harder to explain HEUI injection
@@caterpillarslim1288 why is it hard? It‘s just an electromagnetic valve.
@@Phrew its even harder to explain how a 2 stroke engines bottom end is lubricated... they use the fuel to lubricate the bearings lol
I love when I see other KZheadrs that I watch comment on other videos I watch.
@@Phrew c’mon, that’s a little misleading. I mean there is more to the system and its function than a solenoid, right?
Thank you Dean for supporting the right to repair and help keep old stuff running.
I was thinking the exact same thing
Quality after market parts are so needed. 💯
What an awesome way to make a living !
DIY Mechanic’s Matter!
Something most people can get behind whatever their politics.
I have a PhD in internal combustion engines. I can only say that I love how you approach a subject from its basis. You are an eager experimentalist and the passion you show in your content is inspiring and contagious
get your money back, none of those injectors fired correctly.
Where did you get it? You’re an engineer? I’ve never heard of getting a phd in engines.
🔫
"PhD in internal combustion engines" doesn't even sound real.
I may be wrong, but getting a PhD is about presenting a thesis, not about being part of the research team of a well-stablished initiative or aiding someone in presenting theirs; And if that's the case, you can be a PhD in anything so long as your thesis is accepted.
The thing I think people are most attracted to in all of your videos is the fact that you've managed to retain your sense wonder and excitement into your middle age. It's quite infectious, in the best way, and I've tried to do the same thing, myself. Your son is a luck young guy to have a father who is so enthused by things like carburetors and fuel injectors (and the refractive qualities of water, and pneumatically-propelled baseballs, and so on and so on).
I adore you and your work so much
Nice

I love how Destin goes from nuclear submarines to tractor parts to apollo mission technology to tractor pulls to the incredibly wide myriad of subjects on his popular videos list. This guy is just a grown up curious little kid who gets to explore all of his dreams and take us along for the ride!
great summary of his channel
I hope his new manufacturing business has something to do with rockets!
And I knew anything about any of those things neither even "care" about that much and yet... here I am devouring videos. Destin is gold !
His dad was one of the Saturn 5 engineers... what do you expect? he is a genius.
@@mickeyfilmer5551 And all the way up to JWST.
Those slo-mo burning patterns were so beautiful. Came for science, stayed for the art.
Yeah, there is not enough ‘writing it down’ for this to be science and not mucking about.
Hey Destin, my family had a small business dealing with Cetane testing, so we spent a LOT of time working with various fuel injectors. 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!
That was awesome to see!!! Thanks for sharing!
Fuel injector flame thrower when?
woah
I love how your accent saturation changes depending on when you are narrating vs talking to people. Do you have a saturation dial you turn to adjust how southern you sound. I love it.
Linguists call this code switching in case you want to learn more about it :)
@@kyleeverly9243 I find myself doing this when I visit home state. Or when I meet people from my neck of the woods.
@@ElizabethSwims Me too. Weird, right? I come back and everybody asks me why i'm talking like a redneck lol.. I don't do it on purpose. Just seems to happen.
My friend has a really strong code switch when he talks to his family. We live in Australia but he was born in England and his family moved here when he was young. He has an Australian accent normally but anytime he speaks to his family he instantly swaps to a strong English accent, it's pretty funny.
@@ElizabethSwims same.
Hello there. I'm a mechanical engineer building HP Boilers in Uzbekistan. I must say that I love your videos. You inspire the curious child in me with wonder and awe of the world around. Also, I'm glad to see the Bible references at the end of each video. Thank You very much.
This is my favorite episode of Smarter Every Day. The music, the visuals, and the mechanical engineering - I love it all. Thank you for this video.
Well, today I learned some of the fundamentals of fuel injection. Also, I was not expecting those finale slo-mo's to be as extraordinary as they were.
Most random antvenom spotting
Wow its AntVenom, its feels like a cool crossover
that's litterally how ww1 flame throwers work. You don't actually get burned by the fire, you get burned by the burning fuel that squirts out like a water gun.
@@supertornadogun1690 fr lmao
today you watched a guy burn some fuel.
When you have fire and nervous giggling, you know you’re at the cutting edge of science.
+
With 50 year old diesel tech? 😂😂😂 right.
I absolutely love that your accent comes on a little more when talking with locals from your area! I live in the south as well and notice I put it on when I'm around people with one as well! I think I do it subconsciously.
Love your channel , i am a crop duster pilot in Brasil and in flight school we did learn all about piston engines but one thing is knowing the teory and another completely different thing is seeing how it work , thank you for improving my knoleged and making me smarter every day you are a great guy!
That slow motion video of the flame moving towards the camera was insane. Really mesmerizing
POV - joint at a hippy festival
9:52 Destin's slow motion reaction is so far the best thing I've seen this year.
That's something best experienced in slomo.
Yes, it looks like his mind rapidly went "oops, glad I used safety goggles but if that thing would have caused any bigger fireball, I'd be missing some of my hair nonetheless".
Put the captions on. It says, ".....". lol
"It was at that moment he knew... He done F'd up" or "If I go home with no eyebrows, my wife is gonna kill me"
Safety squints.
Your clear Carb video is still my all time favorite video, movie, gif, EVERYTHING!! I'm a professional harley tech with a shop in Florida, and after years, I still geek out at least once a week on that video.
I ran into Destin about a year ago right up the street from my house. I tell you what, he is as nice and genuine in person as he is in his videos. I was honestly star struck and probably a bit awkward. But he engaged in a great conversation with me about his videos when he went out on the subs with our US Navy. He is just a great guy. Thanks for more great content, Destin!
Destin, you inspired me to become an engineer. Years ago when I was fresh out of the military you were kind enough to correspond with me via email about various photography techniques. I now work in aviation engineering. Along that trail to get to where I am today I worked as an automotive mechanic and I have a lot of these tools and a curious mind. It's very difficult to convince myself to be responsible and not try this at home 😂. Thank you for always staying curious and helping to inspire more people to be as well. I promise I probably won't try this at home. Maybe at work though.
Yeah, at home is definitely not safe, but at work, heck yeah! 😂
recently changed my major to engineering based on legends like destin and mark robber
That's right, do it at work on the clock! Okay realistically I've had to do a spray-pattern test like twice in 10 years, but it's still fun with the old testers!
Did you go to college to become an engineer before you were a mechanic?
The last few slomo shot were incredible, I mean i was so mesmerised to see stuff that you cannot normally witness. Thank you Destin for the fantastic content that you share here, and this is what we need.
Thanks for saying kind things!
@@smartereveryday I would love to know what those 2 books you referenced were, being in the automotive field I’m always looking to Learn new things. Any help would be greatly appreciated!
Getting my A&P and while learning about turbine engines you posted this and it helps so much, I’ll definitely watch again once we do reciprocating engines. Thank you!
Dude, you are so easily entertained. That is so freakin cool. I've spent 40 years in turbine engine engineering and the combustor / fuel nozzle arena has always been black magic. I totally enjoyed this video. Thanks Destin.
Those were some of the clearest, crisp, sharpest slow motion images of fire I've ever seen. Absolutely beautiful and mesmerizing. I absolutely love this channel. Thank you Destin.
It probably helps when the thing you're filming produces it's own light XD Half the difficulty to slow mo shooting is that each frame of video has so little time to collect light that things either need to be really well lit, or end up looking darker, or the shutter speed is adjusted for more light but blurrier images.
you just made a certain pair of guys sad, slowly sad :)
As a robot i find this video extreme attractive
Not saying these shots aren’t fantastic, but I’d highly suggest you check out The Slo Mo Guys if you like that kind of high quality slo mo!
Awesome video, Destin. A lot of general aviation aircraft now use fuel injection (vs. carburetors) so it is cool to see it in action!
the ASI and Destin should do a video together. It would be almost certainly be interesting.
Aircraft have been fuel injected for well over a century now, long before it became common in automotive use, and it's kind of rare to find carbureted GA aircraft with more than 180HP. EFI and FADEC is probably what you're thinking of.
@@Skinflaps_Meatslapper carbureted aircraft are still relatively common in the wider GA fleet
@@Skinflaps_MeatslapperIsn’t the reason for that because a fuel injected engine can work perfectly upside down or in any angle?
@@AirSafetyInstitute Yeah, below 180HP, as I said. Above that point it's uncommon to see a carb.
I love how you take some of the simplest and well used things around us and explain how they work. As a mechanic I know how they work however it is awesome to see them work in slow motion
ok i love how excited you are for this from a fellow mechanic. you ignited the diesel safer than i do in a shop for newbies to show them the "burn process" but im glad you love this. i hope you learn to wrench there is a ton of physics and geometry there that would be super cool for you to teach and just maybe something i might learn about bolt stretching and torque specifications
I wonder how a flame would interact with laminar gasoline flow? Because there is no turbulence would it just never ignite, or maybe the flame being a flow of it's own would disturb the laminar flow and cause the turbulence needed for ignition. These are the thoughts you make us think, Destin 😂
I wonder if the airflow would cause enough fumes to form and be ignitable around the flow 🤔🤔
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. It's why you never use gasoline as a fire starter. If you wait more than a couple minutes, you have a massive cloud of gasoline vapor that's literally ready to explode once lit.
@Hero to his point. I guess laminar flow would best increase the chances of minimal gas build up given minimal surface area. So it would light. But I guess it would be the hardest to light of the flow patterns. Maybe. I've never done the test, just guessing
@@ivanbarreras9445 It'd still be flowing past a lot of unsaturated air so the gas would naturally kind of want to fill 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
gasoline liquid never burns, it's always just the vapors that burn. so in a laminar flow condition it would still just engulf the liquid with flame and would likely disturb the flow at some point. would be interesting to see though.
Don't forget that, in your experiments, you had air at a pressure of 1 bar. Inside a cylinder you have a higher air pressure, resulting in more air within a smaller volume. This is why your flames only started further away from the nozzle instead of right in front of it, like they would inside a motor. Thanks for introducing this company to me. My father-in-law has an old Ford 1600 that's become increasingly more difficult to keep running due to missing parts. I hope they ship to Europe! :)
The thing that was boggling my mind througoutthe video is that there is no air inlet for air on the injection system... this pressurized air you talk about, where does it come from?
@@jakubstanicek6726what do you mean there is no air inlet. You mean like a carb pulls air and full in with the pistons upstroke? It’s not like that with a fuel injection?
@@Duality333 I mean, when he is spraying with the injector in the video, a 100% fuel goes through the fuel injector and the oxygen comes from the air around. If you spray into the combustion chamber instead, you need a way to prefill it with fresh air everytime before injection.
@@jakubstanicek6726 there’s something called the induction stroke mate, think you need to look up how an engine works
@@LR90_200TDI Yeah thats clear when you have a carburator, I was just not sure how that works with injection. So only air is pulled in, and the fuel is injected after that?
Listening to Destin giggle like a kid in a candy store is great. Proves that he is amazed making these vids as we are watching them.
This is a real contribution showing the awesome detail of what happens thousands of times a minute every day! It's fun, it's so much information in a short time - inspirational!
That last shot of the flame engulfing the whole screen in slowmo with the background music 15:40 was literal 🔥
After, I dunno maybe 10 years, Destin still have me curious and fascinated with nature, science and engineering with the happiness of a child. My first and only "ring the bell" on youtube for a decade, and never regreted!
I watch most of your videos multiple times. They're all so entertaining and educational. I appreciate your work! Thank you
This video, like many others turned out beautiful! Thanks for everything!
Super cool video.
Hello Mr Scratches at a level 6, with deeper groves at level 7.
Use these nozzles for your burn tests
I don't trust you, You Rig Everything!
Let's get started 🤣🤣
It's heartwarming to see an adult having fun learning out of curiosity like a child! ❤️
He has such child-like wonder about the world and human engineering
The only difference between an adult and a child is the price of toys ;)
i get that feeling when going to different construction sites and we get to see and test other workers' tools, or learned how they work on their own specialty, we look like kids with new toys
I'm so glad I clicked on this video. Watching the fire in slow mo was so worth it. Thanks for doing this.
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.
I just love how after all these years, you still have the same sense of wonder that you had in the beginning. Cant wait to learn more about this with you!
Honestly I just love the music and the vibes this video gives. It's such a wholesome way of exploring complicated stuff
Love these types of video, excellent work. Dean, thanks for helping perfectly good tractors continuing to work.
I was totally mesmerized by the slow-mo fire part of this video. Please don’t stop doing what you’re doing.
Destin -- a thousand thanks for doing your own closed captions. I love how all the technology terms are correct and the conversations are accurately portrayed. How I wish everyone would do this!
+
Yes, BIG thank you for that!!
big up for letting everyone keep up
Yes, ask KZheadrs who hi the extra length of putting accurate captions are underrated and those are the ones I usually support first on Patreon.
Just wanted to clarify that I meant "all KZheadrs who go the extra length". My glide typing habit makes me type fast but can lead to inaccuracies sometimes.
I just love the way your friend not only remembered being part of your show looooong ago but he was instantly in with what the topic of the video was
My God. That last shot was hands down the best slow motion ANYTHING I've ever seen. Absolutely incredible.
You're a great watch Destin, hope you enjoy what you do because we definitely do. The slow mo makes a process many know in their line of work, become interesting for so many reasons! You are inspiring & funny. Legend. God Bless , Jake in Australia.
I truly can't thank you enough for these videos. Your video on carburetors is probably my single favorite video on the internet! I've been interested in small engines since I was a kid and when I was about 10 my dad bent a crankshaft on a lawnmower engine. He knew it was ruined, so he gave it to me and I spent a summer "dissecting" it and learning as much as I could. I figured a lot out on my own, and became the neighborhood small engine kid. The carburetor was always an issue for me because I couldn't understand how it worked. That video unlocked so much for me and helped me SOOOO much! I actually sent it to a buddy earlier this week because he was having problems getting his snowblower working!
Agreed, definitely one of the best videos on the topic.
Agreed! I already knew how it all went, and worked, been working on small engines for years. But seeing it all in action was fantastic! Visualizing it that way was the best way I've ever seen it explained. It took me a long time to wrap my head around it, when I first learned
Destin, thanks for continuing to pursue your curiosity with random stuff. Your channel has been a big influence in motivating me to return to school after a career in ophthalmology and get an engineering degree. Now I'm 3d printing homes! Your channel is inspiring a generation! Keep it up!
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.
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
I think the best part of watching Destins videos is it unlocks the wonder in each of us on subject we never really considered. It’s an amazing feeling watching and going “holy cow that’s cool” or thinking “oh!!!! That’s how it works. Now I get it”. That gift of knowledge and wonderment is truly amazing.
Farmers kid here & I absolutely LOVE what they’re doing at Cross Creek Tractor!!!! 🤗 May this business grow & thrive always!!!
Wow i love how slow motion makes everything look beautiful.......Bless up....😊
I'm also a Mechanical engineer, currently working in bharat benz, but trust me after I watched your video, im so happy that I choose this stream, it's so amazing...yaa, this small things running big heavy machines....I'm so happy, now I want to learn more deeply...😊
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!!
Please do more videos like this. Mechanical engineering is something you can read in a book BUT the real life experiments are super informative and fun to see in action!
Hey Dustin.. I’m going back to college to learn electrical engineering bc of the inspiration I get from this channel. You’re a goat. And I would love to be able to email You when I have questions.
Destin, you and your videos are like a fuel injector for the mind. Thank you! I'm super excited for the electronic fuel injection one, but I'll be patient since I know it gets way more complicated from here!!
I love when a channel adds their own captions instead of relying on the auto-generated ones. Thank you.
was a particular highlight
I really enjoyed the music over the slow motion shots over sound effects, it really complimented the beautiful shots you got! Thanks for sharing this with us Destin!
It's amazing how it works inside, thanks for this video and the future ones
Thank you, Destin. Your vids always always wake up my 7th grade kid in me who wanted to be an astronaut and loved science, especially physics. I work in a totally different industry now haha. Keep up the good work! God bless you and your family.
If you filmed those flames in front of a solid black backdrop you could totally sell them on stock footage sites. I'd buy every one of them! Absolutely mesmerizing!
15:20 looks like a donut... awesome 🙂.
I went to a certification class a couple years back when Ford was introducing multi layer fuel injection. The slow motion footage was VERY kool. Also the super high speed video of the flame kernel propagation was AMAZING!
love your excitement and passion on learning Dustin!
The last few clips of the single spray point nozzle look amazing
I'm floored by those slow motion shots of the single jet injector, my goodness I wasn't ready for something that looked so beautiful. Just wow!
Destin always does an amazing job at making the recording feel "real" as if you're actually there (probably just the wide angle lens but still), which is awesome
Thank you for the great flame effects I can conveniently use in my work.
This was very interesting, and I'll be showing this to my wife as she wants to learn as much about engines as she can. She bought a 1967 Ford Country Sedan Wagon (not the Squire with the wood paneling), and we are having engine work done on it. The thing I was thinking about as Dean was spraying and lighting the fuel in his shop was that this all takes place inside the cylinders, as he showed in the books he found. So this pattern of fuel-air mixture will be more uniform and easier to light off with the spark, making it more efficient than it seemed in the video. The other thought I had when Dean was at the tractor parts factory was I hope this video going public doesn't trigger an OSHA audit, as it looks like some things need to be cleaned up there.
You have captured some of the most incredible slow-mo flame footage that I've ever seen. Well done Destin, this is why I absolutely love this channel.
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.
Interesting stuff. I am indeed smarter today then i was yesterday. as a bonus, i always LOVE watching fire/flame in slow-mo! thanks for all the different angles!
Thanks for the video Destin! It was very fascinating looking at the injectors firing at such a slow speed, especially with the 🔥
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.
What were the names of the two books you referenced? 12:54 Thank you for always making your videos fun and descriptive at the same time. Your curiosity into every subject makes me interested to learn how it all works. I wish you were my science teacher in high school 🙂
I'd also like to know!
Those are a set called "How Things Work" and there are at least four volumes in the set. They are credited to illustrator Roger Jean Segalat and originally published by Edito-Service SA, Geneva but released in the USA by Simon + Schuster, and George Allen & Unwin in England. How do I know? Because my dad gave me a set when I was younger and I have them in my hands right now. They're wonderful!
@@HermanVonPetri Thanks!
@@HermanVonPetri thanks so much!!
@@HermanVonPetri You deserve the best-answered-question-of-a-youtube-comment-award of this year.
Something about, the slow motion tracking and video of, the flames feels so ethereal!
Great photography. The difference between the nozzles is that the multiple nozzles are fron direct injection engines where the fuel is fired directly into the cylinder and mixes in a bowl in the piston crown. The single hole nozzles are from indirect injection diesels where (mostly) the fuel is sprayed into a pre-chamber. The design of the pre-chamber and the port connecting it to the cylinder means that the air in the pre-chamber spins, typically at 40 times the crank rpm. This means that the fuel mixes extremely well with the air, leading to a good burn. Advantage of IDI is that you can use lower pressure (and lower cost) fuel injection equipment, disadvantage i that IDI diesels can be more difficult to start in cold weather and they are not as efficient as DI diesels. There are some great photo sequences in J B Hayward's book Internal Combustion Engine Fundamentals. There may even be some video out there too, try searching for Ricardo Comet combustion system.
I'm throughly enjoying your channel brother! As an old mechanic, I was fascinated by the slow motion! Seeing the shapes & vortecs as the fuel ignited and burned was just incredible! You are a LOT of fun to watch and listen to my friend! Thank you for giving us all the knowledge you pass along.
Just imagine how cramped all of that would be in a single cylinder! 🤯
Loving this engine series so far! It would be cool to see a video from you on drag racing, there’s so much suspension geometry, weight transfer physics, and tire technology involved on top of just making a powerful engine.
The gasoline injector flame pattern when viewed head on reminds me of the void bullet from the Expanse. Great episode!
What a wonderful world it would be if more people shared your enthusiasm for science! Very inspiring! 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).
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
Great video and great music selection during the slow motion shots at the end!!
Seeing that front of injector view near the end made me realize that's very similar to what we see from nebula burst. We are seeing a stream of particles towards us so the middle is empty, but we see the cloud/ring around it. Very cool.
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.
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).
What's the flow rate of one of them 100,000 hp cargo ship engines?
This would be so cool!
Destin, your kind of childish enthusiasm/curiosity is contagious. You are proof that you can learn new stuff and have fun. Keep doing that, please
A cool video. In a past life (job) I did work on diesel and gas engines. So I do have a very good background of how the their fuel systems work. But it was so cool to see the flame propagation at high speed. Yes we know that the open air pattern is different that in the high pressure environment of the cylinder of an engine. But It's still cool and interesting to see. Keep up the good work.
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!
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!
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!
Also, the video and how much you love sharing the knowledge. And learning yourself.
So glad to have you back in my life. I'm not sure when I stopped watching your videos. I remember the first videos I watched, such a long time ago. I've been a patron when I had income, and in all those years I've changed so much, but you remain an admirable model of curiosity and desire to understand the world. I hope you'll explain how the atomizing happens in the injectors, that'd be useful for my job (fuel boilers service)
11:50 I had a real 'Wow that makes so much sense' moment here. The way you explained this was spot on, very clear and easy to follow👍
This is awesome, love seeing a company step up to the plate to keep old machines running.
