      @Dakoder II Yeah I saw that. Dude was so lucky. The company that made the rifle did some destructive testing and it turned out it was an ammunition problem. 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. The plug from that rifle hit his safety glasses instead of him and probably saved his life as I don't believe he would have been conscious otherwise.

      @Dakoder II It wasn't because the rifle was cheap, it was because the ammo was severely overcharged. In fact the results would've probably been more severe in any other type of rifle. Mark Serbu (the owner of the company that made the rifle) did full investigation into the matter and was fully transparent every step of the way and Kentucky Ballistics continues to praise him and his guns.

    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.

    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).

      @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.

    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!!

    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.

    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

Consider that the injector nozzle designs of Robert Bosch (the type you had with the little nipple in the center) which were perfected in the early 1930s only really fell out of favor in the 1980s!

    Destin, loved the video. Wish I would’ve had this to reference back when I was trying to learn all of this stuff. Just a side note for 13:57 all diesels are direct injected because that’s the only way you can control timing, the fuel has to be injected at the right time in the compression stroke so the combustion happens a certain number of degrees of crankshaft rotation before the piston reaches top dead center. Gasoline engines can be port or direct injected because their timing, or point of combustion, is determined by when the spark plug fires and ignites the mixture

  • Fix This Build That
    Fix This Build That 13 days ago +259

    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 😂

    • 2009dudeman
      2009dudeman 7 days ago

      @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. Lit my hand and leg on fire once trying out a new gasoline 'experiment' (read: me being an idiot).

    • Cyberguy42
      Cyberguy42 10 days ago

      @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.

    • sstroh08
      sstroh08 10 days ago

      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.

    • EFretwell
      EFretwell 11 days ago

      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.

      @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.

    Just want to say thanks. 60-something me has been inspired by you. I know little about mechanics. So now when something breaks and needs disposal I now am curious about how it works. So if possible I take it apart. I examine it and ask questions. I notice the construction and wonder how genius it is. I developed an appreciation for engineering and the mechanisms that I take for granted. I find myself saddened by my own history of merely throwing things away instead learning how to refurbish it or have it refurbished or sent off for recycling. I appreciate the tractor parts business. It is the right thing to do. So much good can come from positive inspiration. I am brought to humbly meditate on God’s greater design for me and the universe by asking questions about how man-made things function. Thank you for that.🙏Smarter Everyday = Blessings everyday.

    • Skinflaps Meatslapper
      Skinflaps Meatslapper 13 days ago

      @Xmysef It's not the primary reason, as most fuel injected aircraft aren't capable of inverted flight. Fuel injection is more efficient for a number of reasons, and you don't have to worry about carb icing up either. You can sort of make a carb work inverted with a few tricks, but if you want extended and reliable inverted flight, then fuel injection is necessary.

    I understand it as air can only react to the fuel it touches, so to have a perfect combustion, you need to have a great fuel surface. Hence why mist does better explosion than big drop of fuel, because almost all the fuel is in contact with air instead of trap in a drop and waiting O2 to ignit.

    This is such an easy way to explain LEL and HEL. It's something that I have a hard time explaining to new technicians within my industry. Although we don't use fuel injectors, it does correlate directly to it.

    nice work , also these diesel injectors are exposed to chamber where combustion happens and they get extremely hot and it helps the fuel to ignite better, now you much smarter 😇

    I would like to point out that in addition to the stoichiometry of the fuel as it leaves the nozzle and mixes with the air, there's also the velocity of the fuel leaving the nozzle vs the burn speed of the fuel. If the fuel velocity is higher than the burn speed, it won't move towards the nozzle. From the moment the fuel leaves the nozzle, it is slowing down.

      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.

    Hey Destin, I have a question. Considering how much simpler fuel injectors are in comparison to carburators, why is that the latter was the first standard for machines? Is there something tech special about fuel injectors that justifies that?

  • S

    It would be interesting to see how race fuel would burn. Like would it react quicker? Different color?
    If I remember correctly de natured alcohol burns blue. That’d be cool to see in slo mo.
    A video on hydrogen engines like the one in that Toyota sedan would be another cool video topic.

    it was interesting to me when i learned the difference between "detonation" (flame front advances due to the supersonic shockwave) and "deflagration" (flame front advances due to motion of the temperature gradient) and that one is preferable to the other. at least in gas engines, "normal" is "deflagration" -- and "detonation" is also known as "knocking" which can damage the engine; is the same true in diesel?

    One of the coolest injector designs he showed us was a diesel injector that uses a stack of piezoelectric crystals to open a valve.

    Great video. Even though I’m an Aussie, I have to agree that it’s great seeing that “made in the USA” sticker. I’m so sick of everything being produced in China and being junk quality. USA and Australia need to bring back more manufacturing to our countries. As consumers, this will cost us more, but it is worth it in my opinion for better quality products and supporting local businesses in our countries.
