I checked out howstuffworks, I knew most of that already; I guess I was looking for more than basics. The only thing I didn't know was how and when the injector works.
Their illustration makes the injector look very much like a....spark plug! It's location and shape in that illustration are similar. The intake and exhaust valves seem to operate similarly.
The fundamental difference that would probably make it impossible to hack my gas lawnmower engine into a low-rent diesel would have to be the compression. The 12hp Briggs & Stratton probably has a paltry 9:1 ratio, which I cannot imagine how I could double for cheaper than outright buying a brand new 20hp diesel.
Okay, I just checked northerntool.com. I's about $200 per horsepower for small diesels. Cheaper than possibly creating all the abominal crap necessary to get the high compression in the 12hp Briggs, but certainly way WAY more than I can spend on such a project.
When we run out of Dino juice, I'll just have to run my mower on ethanol. Maybe that only requires a minor overhaul...
Wow, I have to drive two hours to get Biodiesel, and it costs nearly twice as much as Dino diesel. I bought some to mix into my home heating oil tank.
I'd be looking for an inexpensive used car. I can't afford _any_ car right now, but I'd like to change jobs, at which point the combination of various conditions would make it reasonable for me to do such a project.
I live in a rural area of western RI, and we have pretty cold winters. I've been considering available heat sources to warm the WVO quickly; most people doing WVO conversions, it seems, simply run a coolant line. I wonder if they run enough capacity to disable the coolant fan, or even better, to bypass the radiator entirely?
Exhaust is also another good source of heat, and is much closer to the location of the WVO tank, but I don't know if I've heard of anybody using exhaust heat. Do diesel exhausts heat up like those of gas engines? Do diesels have catalytic converters, and do they heat up to the excessively high temps found in gas engine cats? I'm quite ignorant of diesel tech, having never owned or driven one.
Finally, another idea I have is an auxilliary heater that runs off barely-liquid WVO. Use just enough electric heat to melt the stuff so it can be burned to heat the rest of the tank...
Any suggestions for a web page to teach me the basics of diesels, as compared to gasoline?
Finally, one other thing -- is it possible to hack a small (lawnmower) gas engine to run on diesel? That's another project I've been considering, with a junk lawn tractor I've got whose gas engine needs a new carb.
Is Slashdot the wrong place to look for gearheads to answer these questions? Probably, but I wouldn't know where to find open-minded gearheads...
And you can hybridize it to run WVO. Then it's a diesel and a hybrid. And, besides the free WVO in the tank in your trunk, for your diesel tank, you can put in Biodiesel...
I've been considering a diesel-wvo project car. I'd like to start with a fast diesel car available in the US. Can anybody suggest some US diesel cars that are powerful?
Why, that's silly. Everybody knows how a flush toilet works:
1. User drops load into toilet 2. User operates flush lever 3. Water gizmos and channels create various bits of suction 4. Shit clogs stupid low-flow toilet, lacking sufficient water to lubricate and push/pull it through 5. User applies plunger, which fails to seal over odd-shaped low-flow orifice 6. Unsealed plunger in angry user's hand, while not pulling shit back up, does manage to push shit through the toilet, resulting in complete flush.
Optionally, 7. Angry user in fit of rage operates flush lever again before step 6 is completed, resulting in shit raining down in basement onto clean laundry
That's a sufficiently detailed technical explanation of the flush cycle. Tell me again why residential toilets can't go "WHOOOSH!!!!!" like commercial toilets?
Human bodies don't burn fossil fuels, and don't release carbon that was stored before humans existed. We burn sustainable plant/animal food, releasing carbon that was still in circulation.
Therefore, human power could reduce global warming. On the scale of powering laptops, however, it could not be effective; and on a scale sufficiently large to be effective, it would be intolerable. I'm getting tired and hungry just thinking about it. Somebody get me a can of soda, some Tostitos, and a bed, stat!
I'd like to build a cluster consisting entirely of 486 and Pentium I machines, each with RAM between 4mb and 32mb, to use as a single desktop PC equivelant to a 3ghz machine with 1gb RAM...
Somehow I think, despite my collection of such systems, that it's not entirely practical to assemble that cluster.
These comments raised the ire of Theo de Raadt, leader of the OpenBSD operating system and a member of the OpenSSH development team.
into this headline from TFA and the/. post:
SSH Claims Draw Open Source Ire
Drawing Theo's ire and drawing "Open Source Ire" are very different things; everything draws Theo's ire. As a whole, the OSS community is much more tolerant.
This is *not* intended to be built by you, the hobbyist -- it is no "DIY" kit.
This is intended for people like Sony who want to be selling products based on this in a year or so. For them, $3k is more than reasonable, and not particularly out of line with the dev kits for many more mundane systems.
I agree, but that begs the question...why did they include an order form and why do they accept credit cards? IANA marketer, but I thought that a technology that somebody expects to sell to the likes of Sony, generally has a phone number or an email address, so they can discuss it with the buyer.
Not that I want to defend, or indeed offer any opinion, on any particular war (it's OT for a discussion of the space program), but war drives our knowledge of science and engineering (and new technologies) as well as, or possibly better than, the space program.
I beg to differ about an unmoderated post being ineligible for the descriptions "overrated" and "underrated". A default rating is still a rating. If a jerk posts drivel but has good karma, his default 2 is overrated. If an AC posts something useful, his default 0 is underrated.
Er...every preceding post says to get a lawyer. That makes it redundant, no matter how correct it is.

Too Many Passwords
·
· Score: 2, Insightful
Heheh..."too many" passwords. I've found that the username/password pair concept is so alien and nonunderstandable by so many users that it's entirely pointless. My more saavy clients understand how it works, but use a single insecure password (including one who uses "password") everywhere.
I hate to say it, because the whole concept is so incredibly simple to me, but it's just not going to happen with users.
Further, they want to be _told_ that they're secure, they want to make somebody else suffer when their security is breached, but they do NOT want to work in any way to remain secure, even the ones who understand the concept.
I think, actually, one of the reasons people mod "overrated" and "underrated" is because it's a way to mod numerically without having to choose a description that doesn't fit. The mod probably thought that it was a generally bad post, though not flamebait or trolling.
Also, why can't a post at it's unmoderated default rating be overrated or underrated?

4dos rules. When I found I needed more and more to use Windows, I started using Take Command as my shell, rather than Program Manager.
Anyway, descript.ion, and the labels discussed here which I assume are in fact similar to 4dos's use of descript.ion, seem rather obsolete now. Modern filesystems let you use long filenames with spaces and other odd characters, along with CLI filename completion to make it easier to type them. If you're naming your files in 8.3 (or similar) and wishing you could label them...why not just give them long, descriptive filenames?
For example, if I download the latest version of Opera and it's filename is ow32enen50.exe, in the download "save as" dialog, I'll change it to "Opera 8.5 ow32enen50.exe", thereby saving the original name (in case I ever need it) and giving it a useful description too. If I use a serial number to register a shareware program (like Opera used to be), I'll put that in the filename too, like "Opera 8.01 asdf-jhkl-12345-qwerty ow32enen801.exe".
Another example would be a file containing notes. I might name it "Notes about the broken copier.txt".
If a file is required by the system to have a specific name, I'm likely to put in a 0 byte file with a description named the same + some notes, so it is sorted alphabetically behind, so: "/usr/local/bin/joe" "/usr/local/bin/joe is a good text editor" or "c:\windows\system32\dllcache\ctfmon.exe" "c:\windows\system32\dllcache\ctfmon.exe is an annoying feature that wont go away no matter how much you delete it remove it from the registry turn it off in the control panel and so on so I put in a zero byte file that causes random errors when windows trys and fails to run it"
It's not perfect, but it's good enough for somebody who says "I wish I had this feature" to use until the feature shows up.
The parent did not deserve to be modded troll. He was correct -- the politics, the fact that the exact same storyline could happen on earth now, the religious crud, and the wooden characters all made it a soap opera that dragged on slowly rather than an exciting vision of the future. The only troll-ish part of his post was the final two sentences.
I agree that plot continuity, and even a little bit of soap operation, can work well in sci-fi, but DS9 entirely lost any sci-fi interest, and was entirely 100% soap opera, just in a sci-fi setting.
