I'm a retired machinist. Many years ago I was removing a press fit steel sleeve bushing from a blind hole in an aluminum plate. I filled the blind hole 1/4 with heavy oil put a 1.0000 steel dowel in the bushing hole and gently tapped it to push the bushing out. This is standard procedure using the hydraulic presser to push out the bushing. The bushing was too tight so I got impatient and smacked it hard. The oil ignited with a large pop sending the 1 inch dowel flying 30 feet into the factory ceiling. I felt it pass my ear by a hair breath.

Old trick i learned from a farmer and used to do with my spring airgun, to get more out of it, was to add a drop of gun oil in the skirt of the pellets before every shot. Every time it ignited i could hear the classic sound of cracking the sound barrier and the shot would go further. It also absolutely shredded the o-rings in the chamber, plunger and sealing faces.

You made also a nice demonstration of knocking in a gasoline engine. In the moment of selfignition the piston is still full speed downward and so the detonation is damaging the material. That is the reason why gasoline engines use low compression (no selfignition) and dieselengines use direct injection (no fuel inside during compression). In both engines the time of explosion is delayed until the piston has changed its direction.

@killstrees 8 күн бұрын

Modern diesels actually do start injections during compression just before TDC, usually called a pilot injection, a very very small amount of fuel. This starts the combustion and makes the environment in the bowl of the piston more suitable for a complete burn as the rest of the fuel needed to send the piston back down is injected. Electronic common rail diesel injectors can cycle up to 8 times between the final few degrees of the compression stroke and the first few degrees of the power stroke. This means the engine can make a lot more torque, while using less fuel and getting a cleaner burn. This is also why new diesels are so much quieter. Instead of all of the fuel injected and combusting at once, lots of small injections spread out makes the combustion much smoother and quieter.

@grahamrempel3920 5 күн бұрын

In gasoline engines, you typically have ignition 5 to 20 degrees before top dead center. Not at the top or after. But you do have to be careful to not have knocking or pinging because it will damage the piston.

@nisholger8262 5 күн бұрын

@grahamrempel3920 I understand the preignition time in gasoline engines is needed to build up the flamefront from spark to full flame. Thats why higher rpm need a higher angle of preignition - same time. Full flame shall develop after the piston passed dead center in the phase of expansion.

@horseblinderson4747 2 күн бұрын

Yeah close as you can have Max burn to TDC but just after the more power you'll make but you definitely don't want knocking or pre (before TDC) detonation. But there's some decent power to be had even with diesels just advancing your timing a bit. I think Mercedes diesels are timed -11° they're also indirect injection. Where it sprays the fuel charge into a small pre chamber onto an insert that's metallurgically formulated to hold onto heat. By the time it's done it's pre fire in the injection chamber it's reached TDC and is basically injecting fire at that point.

@GroovesAndLands 2 күн бұрын

Knock (detonation) is a different phenomenon. Knock is when combustion begins at the correct time, but rather than a "slow" and controlled burn, the increasing cylinder pressure (on account of normal, smooth combustion) causes the mixture at the outer edges of the cylinder to detonate (not a slow, controlled burn). The result is a pressure spike that hammers pistons/rods/bearings/crank.

A great video and a very clever way to explain how a diesel combustion engine works. A common everyday example of air heating up under pressure is a bicycle pump. As you pump air into the wheel the bottom of the pump noticeably heats up. This is caused by the compression of the air inside the pump before it enters the wheel.

@Sarvitar 2 ай бұрын

For those who don't have a clue why the tube exploded: with the diesel is that, actually the diesel does ignite in this experiment as required even if its just the smoke without fire we see, it ussually doesn't burn fully even in car engines, thus the diesel smoke we see in cars. There is not enough air to ignite all of that in the tube as only a miniscule spray is needed for this experiment.So the remainder ends up to HYDRAULIC the way through causing that explosion. (7.22)Thats why he didn't feel kick-back.(To get the "yellow flame" you need only to do a 'small spray' inside the tube just to wet the cylinder walls, then put the plunger back in and suddenly press like you did, it might work perfectly)

Great demonstration. I think the reason the diesel blew up the tube is because it burns much more rapidly than the char cloth. The very rapid burning creates a very high pressure that breaks the tube before the piston can be accelerated upwards. The piston has some mass, albeit small, and there is also friction between the walls and the piston rings. These cause resistance to the piston accelerating upwards which in turn does not allow the combustion gasses to expand immediately and hence they create a pressure spike and stress in the tube walls that exceeds its tensile strength.

I loved this! it made me think of a neat campfire idea for camping equipment. a lightweight vacuum spring crank outer tube that then compresses the air into the cylinder, it would be a pressure relief check valve (like in boosted cars) that then has the fire go through that and uses ventruli/bernulis principle to have the combusted gases go into the tip to help further increase the burn to help start a fire like a rocket stove. that way it can be super light weight and compact but creates a solid jet of flame that helps make campfires!

@@1Life4Passion absolutely, despite the incredibly salty comment below of psudo-intellect of a clear defensive jealousy this is one of the simplest designs in human history and might have been used well back in the day with water or treated skin/sinew diaphragms. Its a compression/friction heating system. The valve at the bottom releases its combusted exhaust into a chamber below that forces it to friction-ally squeeze through and mix into another chamber that draws more air in through a shroud around it that has holes that lead into that chamber. That chamber then tapers to another hole that is straight then expands. this causes the air to mix together with any new kindling and or bbq alcohol wet wipes that you might have on hand to produce a simple easy camp fire. The aluminium tube has a screw pattern on the outside of it so that way a basic seal (o-ring above the screws below) top part of the tube can move and expand. This increases the total volume of vacuum that provides a "spring" thats tensioned to the below screw system blow. So it wants to rapidly descend to decrease the volume. The total surface area of the outer ring only needs to be small because the gained total energy potential is based on cubic volume, so it doesn't need much, and using a simple perpendicular crank with a latching gear you gain stored energy that can be released all at once. Same with the screw pattern below as that can then be latched to simple vertical grooves cut through them and can use a simple linear bearing that allows for it to store, in a vacuum, more energy volume potential. This makes it, exceedingly and exceptionally, simple to take apart, clean, repair, and maintain. All while being that much easier to manufacture en masse' for cheap. So profit can be extremely high. Even better though, because the tube below has to flare out that allows for you to slow down the burning gases and store them to more evenly and, extremely conveniently I add, simply have a good burning continuous flame that helps you burn things to make a nice warm & cozy little campfire. So, unlike the dolt who also commented below this comment, its everything simple, easy, and repeatable that will last for a very long time while being extremely reliable. remember, being normal like me means you pursue ideas with passion and hate people like that commentor. No one likes these trolls and its easy enough to forget about them. lets them die in their own stewed filth that only has them exist in terrible ways of life that is negative and toxic for everyone around them as the highly radioactive garbage they are ;) The plunger is just another one way check valve that draws air in as you crank it up to position, the tube gap isn't as big of a deal with you have a little offset ring and o-ring, the oil isn't needed for lubrication when its not used often and wont expand enough to matter, the below section & shroud is a simple stainless steel part that has an anti-galling screw ring for the aluminium part above that is press fit in (loosely) and held in with a simple star headed screw to easily be replaced so you can use a gasket in-between to improve the sealing. The bottom chamber part only needs to be a simple parabolic curve spike that can have the chamber behind it to contain more fuel to burn as it has to go from the outside of the ring of that curve (stators that hold it there just need to be large enough because of the linear check valve stem that you screw in to the upper aluminium tube so its super simple to keep it stable during high velocity and pressure combustion) so that way you can have it draw in air in a outer side to inner side vortexing curve to draw in the extra air through simple plates that have some groves cut in to them to allow for the combusted gases to mixes together with the draw in air to the hole in the center that uses simple hour glass shapes (funnel) to a stem to where the held in extra fuel is. This allows for you to put a screen there (like any gas lamp does, or I dunno 420 blaze it!!! screens) to properly diffuse it and continuously draw more air in to act as a miniature rocket stove that help burn that fuel and create a continuous flame. since it gets diffused to a large area and is still going to run decently hot, it means a larger area of flame can help dry out and heat a larger stick and kindling to area to make a higher chance of a fire in your camp happen. That is the basic system that is pretty easy to follow. it just means blow, suck, squeeze, wooshy burn, blow some more occurs to make a continuous flame that can be placed on the ground easily upside down, or even on its side to help you make a quick and easy camp fire :) hope the explanation helps.

@TheColorsInGreyLife 4 ай бұрын

@@paradiselost9946 well, no there is also a chamber below to burn more fuel that also draws more air in to burn it so its easier to actually make camp fires. That and its using air around you as the air spring because you make a vacuum. Truthfully its far more simple that deciding to put chemicals on a stick that don't get destroyed by water or oxidation over time. but hey dude, a "fire piston" (not combustion ignition with a check valve that has a simple burn chamber) is surely what it is. fire pistons are everywhere, we have so many!

The reason the diesel explodes is that liquids are incompressible and you have liquid diesel. So only the surface ignites, building pressure and since you’re in a diwnstroke, the pressure build to the failure point of the tube since there is no where to contain the pressure of the expanding gas (compressible gas area). With the char cloth, there is still gaseous areas that can absorb the pressure by compressing.

The tests with the diesel were experiencing pre ignition, this is a great visualization of how dangerous preignition is to internal combustion engines. Edit: i also think the compression ratio was too high, might have something to do with the pre ignition

Maybe you can try heating diesel to its Flashpoint which is something like 65°C or something. That Will allow it to be in a more volatile state and require less mechanical pressure from your hammer. Maybe... (I'm no expert) And thank you for all your really interesting and educational content!

I am not an expert in Thermodynamic, but i remember ignition Pressures over 3000PSI in a Heavy oil Diesel Engine. So the Tube has to Whistand extreme pressures while the Piston still travel down... Í heard also from a Diesel Pogo Stick wich accelerate a Person into the air just with a tiny drop of diesel in a piston.

You mustn't have tried a friction fire roll yet. ;-)

@lady_draguliana784 4 ай бұрын

@@ElementofKindness I have encountered the friction fire roll and imo it's inferior. 😅 the piston works with anything flammable to hand, and can even dry the kindling in seconds and starts a fire in seconds, with minimal effort. with char-cloth I've gotten embers off of just one hit! full fire in 10 seconds. (note that he's using huge diameter bores here, but with a proper, pencil-width bore it's much MUCH easier and faster) from what I've experienced, only a BIC would be faster, especially if it's damp out. and unlike a BIC or a strike rod, a piston doesn't run out of fuel, you can just grab anything that'll burn and it'll work. 🔥♾

your left hand holding the tube moves it and give a weak point at the bend to break the tube., would like to see the tube fixed in place at the top too. not saying it will prevent the crash, still, would like to see the full power.!

what, the rotary vane pump that despite 150 years or more of people thinking its going to "wonderful", has never had ANY successful running prototype? still waiting on him to confess that it was a practical joke and he has you all fooled cus yall gullible.... its "rare" because it isnt an engine, and produces no useful power in any way whatsoever.

Very cool idea man. Keep in mind your "injection angle" is much too early. It should blow it up every time. Think about when the diesel gets injected on a Diesel engine. Great video man.

@@WarpedYT I could tell you were on that trail right away you pretty much mentioned it in the video - just worded it differently. Honestly man I'm really impressed at how you made all that to begin with. I wonder what would happen if you made the cylinders out of metal. Not that we could see much, but maybe a cut away cross section afterwards might show putting from "knock" or something? Or maybe you'd have made a gun and put a hole in the ceiling 😂

I heard of these some time ago, cool to see them in a see through version! Speaking of compression ignition engines; could you do a see through HCCI (homogeneous compound compression ignition) engine? Those were a popular way to power RC aircraft and are commonly referred to as 'RC diesel engines' as it works in a similar fashion, but with a variable compression ratio. They don't burn normal diesel either, but a mixture of ether, kerosine and castor oil.

One major difference between doing this with diesel vs cloth is diesel fully mixes with the available air while cloth only has its own surface area to react with air, so you get much faster and more thorough combustion of available air-fuel mix with diesel than cloth. Not surprised at all that pressure goes up too fast for the tubes to survive with diesel.

@WarpedYT 4 ай бұрын

That's a good way to put it, I definitely think it's correct And what you said matches exactly what happened.

@teardowndan5364 4 ай бұрын

@@WarpedYT Another thing that likely plays into it is that the diesel air-fuel mix has a far more homogeneous temperature for compression-ignition than charred cloth. With well-mixed diesel, you really get everything igniting everywhere all at once. With the cloth, you have solid clumps which are much harder to uniformly warm up to ignition temperature, especially when that heat is provided by the layer of compressed air around it insulating it from the rest of the air mass. That is probably why you didn't get much of a reaction with cloth until you hammered the plunger for a second time after a first partial combustion kicking temperatures up a few notches right next to the remaining bulk cloth.

@tedantares2751 11 күн бұрын

What happened with the char cloth at 4:20 is it ignited as a result of heat accumulation after several strokes. You effectively transferred the energy of the sledgehammer to the air inside the tube and the tube walls, and when the air got hot enough after several strokes, the cloth ignited

My guess is that every time it explodes, you blow off the coal dust from that fabric. Diesel needs at least 25 bar to ignite, which you have, but the injection pressure is about 1500 bar on the injector to make it burn the way it does. Because you don't have the correct injection pressure and the ignition pressure is wrong at the right moment there is no chance that the diesel will burn. It's good, it will come out at 6:06 when it explodes, it will spray the diesel and it won't ignite. Get an injector tester and try spraying diesel (with the injector) on a lit candle and see how it goes to burn.

@mrjoelpt 2 ай бұрын

I think the tube is blowing from the pressure weakening the tubes with micro fractures, not actually exploding from ignition. I would suggest trying the same inner diameter radius but increased thickness, oh and decrease the fuel amount that's wayy to much 😅.

It looks like you added a LOT of fuel in there. I wonder how much is used in a single ignition cycle in a diesel engine where volume is much larger.

@davidquirk8097 9 күн бұрын

Diesel runs about4.8 M Joules /kg energy content so you have way more energy content in you tube than just with char cloth. Normal peak cylinder pressure in a truck size diesel is between 100 & 200 bar ( depending on emissions control level) or 1500 to 3000 psi but what will really make the difference is the burn rate and hence the rate of pressure rise.
