Hello, It could also be the opposite, that is, the piston could descend from the top towards the cylinder, but in this system it is too light. However, there are hammers with pistons that go down into the cylinder. Other uses, certainly.

Must have been designed by a woman.

Diesel fuel instead of gun powder in a ramset 🤷‍♂️

If you think this seems weird look at ww1 era radial engines. Some of them had the cylinders rotate around instead of the pistons moving

@@liamschenk5893 yep, I’m familiar with some of those. I’ve seen some up at Oshkosh air venture. It’s amazing to see them even run. There’s one where the lifters are exposed and the oil slings out. Crazy.

Is it broken?.........

@galewinds7696 was cementing on the hammer. It's basically a 1 cylinder diesel engine but there is no crankshaft. You have blows per minute but no actual rpm.

And what is your miles per gallon ?

and the piston is stationary, and the cylinder doubles as a 8 ton hammer

@@Wildstar40about 12 inches to the gallon

Hop rod!

That's pretty much what it is. Just bigger and no pegs 🤣

That would be a very big sand worm! Imagine how many worms that would attract.

Lmao

An old grandfather of a worm

Then it pulls the piston right out... boss I don't think it's supposed to do that... last words before the giant worm pulls him down the tube 😮

Maintain your shit. A well maintained transporter is extremely reliable. If it's being fuel hungry and unreliable, sounds like your injectors might be going bad. Badly worn nozzles, maybe even one or more stuck open. You might want to take a look at that.

@@remcovanvliet3018 I've owned it for 5 years from new, never missed a service, covered 77k miles, always serviced and maintained at main dealer. It started using water so I took it to the service centre, the EGR cooler was leaking cost 4k for repair and had major service along with gearbox service at the same time. Engine mounts replaced due to vibration, cured for 2 months only for vibration to return, turns out it was a problem with the crankshaft, another 2.5k spent along with new engine mounts again. So forgive me for my pessimism when I don't think a VW is reliable even though I maintain my shit....

My girlfriend's 2004 VW beetle is retired to pick ur part with only 38k miles on it, piece of junk.

Are you talking about an air-cooled Type 2 bus? Yeah, they can be needy but, because they are relatively easy to work on, they can be kept in good order and reliable. Especially now that they are fetching insane prices. Geez, I remember 20 years ago I could've picked up a mint '75 VW camper for $5000.

@@BlackPill-pu4vi no, mine is a 2019 type 6. I wish it was a type 2 like you say much easier to work on and probably worth more than the very needy one I've got 😂

Exact. The process cannot be automated, it is dangerous to then stop the process in case of malfunction. The system requires manual dexterity to allow the operator to immediately and precisely interrupt the descent of the pole into the ground. It would be easy to automate the process. But in this specific sector it is not possible.

@@thecatSimois the little balancing piece your throttle? Determines how much fuel/air is mixed in for the combustion? I noticed the more they slacked that line the higher it flew.

@@thecatSimoit’s like watching a huge version of those powered smithing hammers

@baconthevainglorious7371 That's right, the accelerator is totally manual. You saw well.

@@thecatSimo Thank you for the explanation. I was wondering why they needed a man to do it, but now I understand.

They actually have those. 😆 There's a KZfaqr named: The Backyard Scientist, who bought a 1960's (I believe) pogo stick that used gasoline and a piston to bounce you back up. But they discontinued them because there dangerous. The kickback is violent and makes people buckle there knees. He made a video on it and tested it out for himself. 😉👍

​@Dusky_The_Husky Yea the explosion acceleration was just way too instant

It doesn't get much simpler than this

HI. You are absolutely right. Live the noise gives you goosebumps. The power delivered is impressive.

Nor did I. What a great idea,

Brings back memories of ex GF, she use to call me "Pounder" never knew what she meant

Definitely not a pneumatic hammer

Diesel hammer / pile driver / compactor i guess depends on what aplication its used for a might big for small fence posts..😂😂

The manufacturer calls this a “guide rod diesel pile hammer”. It is also known as a pile driver. It is not pneumatically powered.

This isn't "pneumatic", it is powered by the diesel mechanism. It operates exactly like a 2 stroke diesel except instead of the piston moving and turning a crank, the cylinder and head moves and gravity powers the compression stroke. Cylinder comes down with fresh air, the compression heats it, the fuel pops off when the temperature reaches the critical value, half the force goes into directly driving the load, the other half goes into the cylinder, and returns to heat the next charge of air, and the cycle repeats as long as the operator keeps opening the fuel valve at the right time.

How dare you run this at all? You must learn to sit in a cave in the darkness and munch on bugs.

Let’s hope they are exempt from that madness !

No they would always be in for repairs having to do a DPF burn off with ADBLUE top up with the check engine light on needing a scan tool diagnostic!

This is the defacto standard method. Nothing beats it for simplicity and efficiency.

Скорее всего в поршне. В его донце

In the piston crown

I thought the same thing for a second. That is pretty awesome.

"THATSNOT MINE BABYYY!!! Honest. 😂

Hope you had a higher moly grease 😂

Ah, those were the days ... hammering whole night

And 20 yrs later she's a hammered troll

Or so you're told

😂😂😂😂

in the ass of EPA i think 😂❤

It's got an emissions delete tune and kit.

Your mom likes the same treatment as well.😂

Sorry to say, but the pressure (and heat) is far from what is required for forming carbon into diamond. Still, it's an impressive amount of energy and force.

8 ton weight plus the energy greated by thr diesel combustion. It's gotta be pretty crazy

Hi, two-stroke diesel yes. It is an engine that today is used almost exclusively for the propulsion of ships, its cycle (intake-compression-expansion-exhaust) is carried out in 360°, i.e. one revolution of the crankshaft exactly like in two-stroke engines. The main characteristic of a two-stroke Diesel cycle is that of having an exhaust opening (called port) in the cylinder walls (as in two-stroke engines with positive ignition), this port is controlled in opening and closing by the passage of the piston.

​@@thecatSimo Great explanation. I have a piston port 2t gas engine that operates on that principle.

Though it's not done much, when these engines idle, they speed up considerably.

You are right. But the live sound is scary..

Wouldn't you prefer it in mpg?

I guess there is No need to Test this thing. It Looks Like the Most Basic compression ignition engine you can build.

Cylinder bore matches perfectly with piston rings. The mouth of the cylinder is slightly larger to allow for a softer entry. It's simply a traditional Diesel system, but on a much larger scale.

​@@thecatSimoThanks. It's an impressive machine.

Hi, They are much more efficient. They are much more powerful. This is essentially the reason.

​@@thecatSimoand here I thought all diesel hammers operated about the same.

Probably by truck. A couple of Jerry cans just won't cut it. Looks like this thing gets terrible mileage too.

I worked for several years as an inspector for the DOT using the second type (and more common) of hammer in the video where the piston is moving up and down. The crane operator is running three cables - one for the pile hammer leads (framework), one to lift the piston to start the operation, and one for the pile being lifted into the leads and driven. There is a rope attached to the fuel supply valve to shut down the driving once bearing tonnage has been reached. The bearing tonnage is predetermined for the use. It is calculated by a formula involving the weight of the piston, the height of the piston drop, and the weight of the pile itself. This gives you the necessary distance per blow to achieve the tonnage of bearing designed. So, if you calculated that a minimum of one half-inch/blow is needed, you mark the pile and count 10 blows, mark again, measure. If measured less that 5 inches, the fuel supply cut-off rope is pulled, halting the driving on that pile. It is important to halt not only for cost (paid by foot driven) but because cast-in-place piling are designed to be 'hung' in a layer of suitable soil to gain tonnage via friction. H-piling are driven to bedrock and must also be halted to avoid doing damage to the pile.

no it doesn't. the compression and fuel ignition lifts the hammer

They work just fine in coastal areas

It is practically impossible for it to fail. And iron with iron. You only change the rings, but they last a lifetime

It's an emergency switch. It possibly could be automated but a guy with a rope is more reliable and way more cheaper than anything else.

The guy with the rope is not only the failsafe to prevent runaway, but he is also a trained operator to let the stroke be large or small, according to how he times it; also to be able to stop precisely at the given mark.

He'll cut off the fuel when they're done pounding so it will stop

exactly by pulling the rope when the cylinder is in the maximum compression phase, it takes a lot of experience to make it go fast, just as much to make it go slow.

HI. you can't see it, but in the center of the piston there is a diesel injector. It is activated by the operator with the movement of the rope.

Diesel's dont have sparkplug

I hope....you're making a joke....😢

Your right, they have glow plugs. ​@@wadewilzon
