Bio-diesel Fuel / Re: Tyson- Conoco/Phillips Biodiesel politics
« on: August 22, 2007, 10:47:37 PM »
Me too. Whither my country? Was I just a dupe? Was I imagining things the way they were? Is this America? (Is that Canada?) We used to joke about the nazis - about them demanding "your papers! Snell!". About political proscutions, and about the camps. Now it's us.

In highschool I took latin, the teacher, an Austrian lady, would tell us stories about living through the war there, and make us translate them into latin and write them down. Hard stories to hear. Writing them in latin burned them into the brain. That, of course, was her purpose.

The result? I know, and wish I didn't, what going on. And there's nothing I can do, nothing anybody can do. Just like it was for her, it is for us.

Hey Doug - This paper caught my eye and I throught that you might be interested in reading it, even though it's off topic just a bit...

Engines / Re: using a gas hot water heater tank to cool lister
« on: August 20, 2007, 05:13:44 AM »
You have two goals that would seem to interfere with oneanother. One is cooling. You are going to have to get rid of about 5 kw of jacket heat either with an automotive type "radiator" or through the surface radiation of a tank, or both. The other is storing heat to use when you want it. This requires preventing heat loss.

In order to use the coolant liquid as hot water you are limited to water as coolant - obviously. This presents corrosion difficulties.

A shell and tube heat exchanger running corrosion inhibited liquid in a closed cycle through the engine is logical and good practice. Plumbing that shell and tube to heat water in an insulated tank is also logical. Plumbing either a tank-cooler or a "radiator" is also necessary in order to prevent over-temp situations.

A normal hot water tank with the insulation stripped off , eg 35 to 40 gallons or so, is too small for a 6-1 at full power and sustained ops. Way too small. With the insulation it is, obviously, far worse.

The heat calculations are well done on the site - eg the size necessary for radiator, tank, and so forth. Look through my past posts and you'll find 'em. I made mistakes and corrections until it got very clear.

Listeroid Engines / Re: Air Intake noise?
« on: August 18, 2007, 06:02:14 AM »
the cfm given on the drawing is 100 CFM. see:

 http://www.solbergmfg.com/Download.aspx?file=/Upload/Drawings/PDF/FS-19P-150.PDF

solberg says:  "...However, you can get the FS-19P-150 from any local Grainger store.  Their part # is 4Z682.  They should have some in stock. In terms of buying direct, we have a first order requirement of $100 net.  This unit would be $40.35/ea if purchased directly..."

 
Should be a simple matter to adapt the stock intake to the solberg silencer with a piece of hose and a couple of hoseclamps. Alternativly brazing a pipe coupling to the intake manifold is trivial. One never knows, however, how brass will behave on a diesel - the transients can cause fatigue surprizes!

roger that!

The experienced advice of an electronic engineer friend with extensive hardware experience plus personal experience that's been rather costly has made it quite clear to me that a sinewave is essentisal to some of the gizmos we use - like switching PS and the 'puter tower power input.

It's true that avoiding combined devices - like the DR2412 - simplifies troubleshooting and so forth. The Trace stuff is so reliable however that I don't expect serious trouble. I have on the agenda adding a descrete alternator-charger, but only intend to hang the drive belt on the house wall in case the device is needed, eg the DR fails.

trace DR2412 just under a grand - solves problem.  suggest using a 300 watt  pure sine wave inverter for the computer though.

running an automotive alternator involves considerable windage loss and considerable other losses. Worse, the charging curves are primative an ineffecient. modern combines inverter charges have a microcontoller with logic that does a better job.

DR series can be stacked to give 220 vac.  read up on the dope at url above.

Ah yes! Worship of the "golden calf", so to speak.

The Great Military Geniuses - whatever people call 'em, are doing a fine job of taking us to year zero..., 'course they plan to run away with their loot to Costa Rica or somesuch...

What is "RUG"?  And what's "RVO"? Sorry, maybe I'm just dumb....

Generators / Re: chain vs belt drive
« on: August 12, 2007, 04:48:58 PM »
There is no advantage to using dual belts. Use one belt that is big enough to transmit the power. Keeping things simple is a great advantage. It is vital to establish correct tension. If you use a gates belt then you can consult for free with gates and they will tell you exactly what tension to apply. They are experts. They are free. They make very good belts.

Skeeter, I wonder if the acetone is just cleaning the injector tip passages and making that, presumably fouled injector, spray properly rather than dribble.

When there a coking problem in one cylinder of a twin I'd suspect a fouled injector.

Reduced soot formation in modern engineered engines is, I've read, primarily a result of improvements in the injectors and injection pressure curves.

This seems to imply that an injector designed for the fuel you're using would be good. It also implies that a modern electronic injection system would be good.

The costs associated with that approach might be very high, except that it may be that the electronic injectors from a modern automobile could be adapted.

One would lose the simplicity of the Lister design, but gain economy and clean combustion.

It's not an all or nothing way - simply adapting a better injector with a finer spray pattern might yield satisfactory results - it's an approach that would seem to begin with a visit to the injector-pump guy.

Intake noise engineering is the same as exhaust - same formula, different speed of sound because the temperatures are lower. It may be that a nice new clean car muffler on the intake between the filter and the valve will suit.

I am thinking along these lines myself, thanks to an alcoholic neighbor who gets to yelling at me on Sunday evenings, if I'm running the l'oid.

Why there's NO CONNECTION at all with dear leader and his minder, what gave you the idea that there was? Do YOU think Cheney's "Dr. Evil"? Do YOU think that there's a resembleance between GW and a chimp? I, for one, certinly do not! These men, even though they dodged the draft and went AWOL are PATRIOTS, pure and simple! Well, aren't they?
