Sand Art: Dunes, Desert, and Outdoor Creativity

HI,

I just removed my Duesen combination units because Rainer is going to install new Duesen units there.

Now the seats are full of sand!

I had cleaned the print head perfectly, but some particles were stuck between the nozzles and the print head (the red area) (after 207,000 km, some of them had accumulated there).

Besides building a dust extractor adapter and opening a valve (to ensure proper ventilation), I can't think of anything else.

How can I clean the seat holes more thoroughly?


"Thank you."

How can I clean the Situloecher further?

Hi Martin,

1. Stuff the actual holes leading to the combustion chamber with something (like pieces of foam) to prevent sand from trickling through.

2. Moisten or lubricate cotton swabs and use them to wipe away the sand or dab it off the sealing surface.

Hi Martin,

Just insert two thick straws into each other, place the opening into the hole leading to the combustion chamber, and then blow air into it.
It works great, and if your straws are long enough, the dust won't end up on your face .

Best regards, Rainer.

How about Sangria straws?

Hi Martin,
'If you previously spilled oil around the nozzles (as the picture suggests).'
and nothing has fallen in yet, find a nice pen (theirs).
(The conical shape fits quite well into the opening), insert it into the hole.
Blow out the dirt with compressed air (this has always worked great for me so far).

[edit]
- Hold the pen firmly.
- Do not blow directly into the pen, but blow around it .
- Compared to foam rubber, felt has the advantage that it does not disappear in the combustion chambers.

Yes, I oiled it beforehand.

It seems there was more dust than oil, so the dust wasn't completely saturated.

In addition, the coating on the injector for cylinder 2 has peeled off and is now hanging inside the hole (still visible).

Intensive vacuuming is probably the only thing that will help now, especially to remove that piece of debris from the combustion chamber.

I'm somehow now worried about my cylinder bores .

Attached: Cylinder 2.

Damn.

I initially encountered an issue during the gear changes after releasing the brakes.
The dental tool was cleaned as much as possible by scraping off the debris, and then blown clean with compressed air.
And then, finally, apply the oil to fix the remaining dirt.
Then, remove the nozzles (one at a time) and use a pen, dental scraper, and...
Blow out the remaining debris with compressed air.

Evtl. kommst du jetzt auch mit einer kleinen Entlötsaugpumpe ran. They tear those apart.
Based on my experience, a crumb sweeper is often better than a vacuum cleaner for cleaning up small crumbs.


Best regards,

Hi Martin,

Just remove the glow plug and blow some compressed air into the hole.
Most likely, the dust will just be blown out through the exhaust valve anyway, so I wouldn't worry too much about it.
Take a look at how much dirt a so-called "sports air filter" lets through over the kilometers; it's more than your little crumb of a car.

Best regards, Rainer.

I simply inserted a 5mm hose into the vacuum cleaner and sealed it with electrical tape. This allows me to easily suck up the crumbs.

Otherwise, I share the same opinion as Rainer. I also don't believe they will clean that in the workshop.

Is a cross-sectional enlargement planned ?

OK.

Thank you for the tips.

Now I just need to figure out how to get electricity, compressed air, a vacuum cleaner, and other "heavy equipment" to my old rental garage.

The power went out, and so did the vacuum cleaner.

But the air...

I had the same problem with CR injectors. I applied Tip #2 from Ulf. A long-handled artery clamp helped quite well... I then clamped paper towels into it and soaked them with cleaning solvent. I ended up using about ½ liter of cleaning solvent, a roll of paper towels, and half a package of cotton swabs.

In the injectors of the first generation, a large amount of dirt accumulates between the nozzle shaft and the bore. Bosch has improved this by machining annular grooves into the injector shafts at the top end, into which an O-ring is inserted. This seals the bore against the ingress of dirt.

That's nothing new, but maybe you could install sealing rings before reinserting it.

I simply inserted a 5mm hose into the front of the vacuum cleaner and sealed it with electrical tape. This allows you to easily suck out the crumbs.


I did it the same way as wolfi_b, and it worked wonderfully!

The oil-soaked sand and oil mixture also turned out well.
Then I cleaned it with a cotton swab, and that's it.

Best regards, Georg.

Hello.

Fill the hole with expanding foam or silicone, and then pull out the hardened plug with a corkscrew.

@Above

If you meant that as a joke, I would mark it as such.

If you meant it seriously, I'm feeling a bit dizzy .
You're not seriously suggesting injecting expanding foam into the cylinder head bolt holes... there are probably more spectacular ways to render a cylinder head unusable.

I'm sure that all the sticky stuff you're injecting in there will adhere very well to the head, and the spark plug wrench won't do anything anymore. Furthermore, this stuff will push the sand/dust even further towards the hole, and it will trickle into the combustion chamber.

I think removing the vacuum cleaner and possibly the glow plug would be a good way to create proper ventilation. Perhaps using a compressor to help clear the glow plug hole would also be beneficial.

Then, use a cotton swab dipped in oil to help.

Unfortunately, I forgot to take the "before" photos again; otherwise, we could have made a photo story out of it. (I could fake "before" photos during the assembly .)

m;

It was actually meant seriously .

I had assumed that the shaft was oily enough to prevent any adhesion of the corresponding substance.
If you fill it from the bottom using the trunk or a similar attachment that comes with it, shouldn't that work without pushing sand in, quite the opposite?

Before anything else, make sure to seal the combustion chamber opening with a plug of foam, earplugs, or something similar.

It was just an idea.

Hot glue would also be interesting, or wax! You could pre-install a corkscrew or something similar, like with those ice cube molds.

Your idea is entirely dependent on the integrity, and therefore the non-liability, of the drilling process.

But that's exactly the problem:
There was so much dust inside that not enough oil reached it, and the dust started to clump together. You can see this in the photos, as the sealing surface of the copper rings is covered in clumps of dust.

So, I would have to add more oil, but that could again allow sand (this time mixed with oil) to enter the combustion chamber. Also, I want to remove the stuck piston piece from cylinder 2 from the combustion chamber. And the only way to do that is to apply force "from the inside," by blowing air in through the glow plug hole and vacuuming it out through the injector bore.

I would still advise against any kind of gluing actions, but I don't want to completely condemn your idea.

Greetings.
