      Hey Destin,
      Just shared your circuits jingle with our co op today, he couldn’t remember some formulas but twinkle twinkle little star, Power = I^2*R I don’t think he will forget.
      You should show how injector timing, angles, and use of multiple nozzles is used to make an ideal mix for combustion in a gas engine.
      There are so many engineering principles in play.
      We use multiple sprays from multiple nozzles (with changing combinations) in a single injector each time the cylinder fires. I have some cool cutaways and thermal imaging of the inside of a piston, could probably recreate it if I get the time.
      Keep it up man! Great work

I'm not a fan of that breach design, personally think a falling block design would be easier and stronger. That video shows the importance in wearing safety glasses.

      @rotoR Col. Diesel engines(from this video) most commonly use a "rack".(the master fuel pump injector system is more conplicated to explain.) The rack is a gear that connects all the pumping pistons. A pump piston squeezes the diesel to increase pressure till its respective injector fires. The pumping piston has a (albeit weird) v groove cut into its side. There is a bypass pinhole in the cylinder. It is worth noting the pump piston and cylinder are rather tight tolerance. What controls the amount of fuel injected is determined by where this v groove passes the bypass hole in the cylinder wall. The pump piston rotates according to the rack position.

    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! :)

    That part was amazing when you noticed the fuel ratio gradient. It is amazing to be a mechanical engineer. Theoretical knowledge isn't enough to understand the complexity of these mechanisms. Your videos helped me a lot to understand these things. It is true that particular type of fuel requires certain amount of air to get ignited (stoichiometry ratio is for complete combustion). Thanks buddy @smartereveryday

    Nice work Destin! Diesel combustion is an incredibly fascinating topic and there have been so many different attempts to make it work better and better. I have a super old book that describes common rail fuel injection by Italian inventors from the 30's - crazy old ideas are hidden in the history books awaiting rediscovery.
    I like your torch method for ignition. It's not too far away from reality, especially if you have a really lean flame so there's still sufficienty oxygen in the hot zone to make it combust. One of the challenges with diesel combustion is the mixing process of the fuel and air which is why many older diesels use swirl generated by the intake ports to get as much motion of the air charge as possible during compression. An alternative is to actually use the fuel jets to do the mixing and this is known as a quiescent chamber for obvious reasons.
    Another diesely problem that is somewhat obvious from your high speed video if you know what to look for is diesel knock. This is where dribbling from the start of the injection allows a large-ish amount of fuel to be injected and mixed before combustion starts which causes it to all go off explosively causing a rapid cylinder pressure rise and exciting all the structural natual frequencies of the engine which we hear sounding something like hammer blows on steel. There are several ways engineers have tried to overcome this, firstly by increasing the crack pressure of the injector but latterly with electronic control the world has been "rate shaping" with multiple pilot injections - 5 to 10 tiny injections prior to the main injection in order to get the combustion started before the injector piles on the coal. This can electronically control the cylinde pressure rise rate (hence the term "rate shaping") and is one of the marvels of today's diesel injection systems. Obviously this has driven the demand for more and faster injection control leading to piezo-actuated injectors now. Truly cool tech!
    Anyway, thanks for bringing this to the world and for the lovely high speed photography. Like you say, it's truly beautiful if nothing else!

    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.

    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!

      @Hero While I agree gasoline shouldn't be used by the uninitiated to start fires. It's still my favorite way to kick off a big fire. Granted, as you point out the timeline needs to be tightly controlled and you still want to be a good 6-10ft back and using a long stick to start it.

      @Hero Same goes for pouring gasoline on a lit fire. Dangerous, but at least predictable. However, I've seen what happens when someone doesn't pour it close enough and it just pools on the ground, apparently harmless... until it explodes. If gasoline doesn't burn immediately, get back and stay there until it does.

      Modern higher efficiency gasoline engines use direct injection like this so it has to be possible some how haha. They use an electronically controlled injector that is way more precise than the injectors shown in this video. Instead of an injection pump having to override a spring they have a constant supply of super high pressure fuel (25000 psi plus) fed to them and an electric solenoid opens and closes a valve to pulse in the fuel. They are so precise that they can fire 20+ times per power stroke of the engine. Crazy fast! Haha.

      As the turbulence increases flame front speed increases. This is important becuase at low rpm the time for combustion isn't long enough for the time availible at high rpm. However, as rpm increases the turbulence increases and the flame front from the spark actually travels faster and keeps up with the shortened time allowed for combustion.

    Destin! You should measure the pressure punch and speed that the single flow nozzle produces. Almost like a pressure washer. I think this would be interesting because instead of just checking the pressure it takes to pop the “check valve”, it would measure the quality of the flow!

      @Yora Or works the other way, like a NY/NJ accent has taken over Miami to WPB. I grew up in Jacksonville near the GA border, but always had Northerners since a port and winter retreat in late 1800's, so a mild Southern accent which seems to extend to Waycross, GA. Southern accents vary, from the deep and thoughtful Tidewater VA planter to the twangy Appalachian. The later might be closer to how 1700's Scots talked, maintained due to isolation. BTW, Hollywood usually gets it wrong, showing Confederate flags in Appalachia while most there supported the Union.

      Everyone does that. If you're in a different part of a country for a while, you even start imitating the locals.

Last year before learning the engine was shot, I got to meet our local fuel injector repairman downtown and he walked me through his refurb process. What a crazy coincidence to see this video recommended to me. Doing stuff for the joy and curiosity of it is just the best, isn’t it? 😊

    Thank you for this video! And thank you for supporting the right to repair! Just one note/correction: in fuel injection engines, the air/fuel mixture happens also upstream to the engine, in the intake manifold (like the carburettor ones), so the mixture enters the cylinders already homogeneous and even. The type of engines where you've got to have perfectly even nozzle spray inside the combustion chambers "downstream" from the intake manifold, are direct injection engines (where it applies what you said about having rich mixture on one side of the cylinders and a lean mixture on the other). Bye!

    Loved this video! Excellent work. When you talked about the burn boundary of the jet I started thinking about ignition alternatives to the torch. For example, as you are applying pressure to the pump lever, there is likely a lever position where optimal fuel has been expelled. At that position, a contact could engage and a spark plug in front of the nozzle could ignite the jet. Then to experiment with burn boundary, the spark plug could be moved closer or further from the nozzle to determine where the optimal fuel-air boundary is,
    Like you often do with your videos, you get the creative juices going. Thanks.

      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.
