I honestly cannot remember the last time I wore a watch.  It HAS to have been at least 30-35 years ago now. Where timekeeping is actually important I have very specialized and accurate time bases.  I do not wear jewelry of any kind either.  No necklace or rings to get caught up in spinning machine tools or become an electric heating element if caught in a storage battery bank misshap, possibly burning off a finger someday.  Speaking of no jewelry, I ENJOY every minute of not having a nose ring either.  ;D

Wasn't that Nissin?  You open the crankcase inspection cover and will see their nissin parts.

Anyone heard from Pat at Altopro lately?  He hasn't had a thing on ebay for a very long time and isn't answering email.

anyone thought of using a surplus elevator motor/generator, basically an electric motor driving a dc generator. the motor could be disabled or removed or used as a/c power at the same time you were charging batteries.

I have been searching for such a beast.  I want a large diameter open frame unit, many poles, out of an Egyptian Pyramid or just a bit newer.  Not the newfangled junk.  My desire is to wind/create a really low speed alternator.

On a more serious note.  In case someone would like to experiment with reducing the number of running cylinders on a 4-cylinder diesel automotive engine I have a 1681 cc Nissan diesel engine in a 1985 Sentra that I am trying to get rid of cheap.  Details in the Lister Marketplace forum.

I had a commercial compressor a few years ago that was built from a small block ford engine , used one bank as the engine and the other as the compressor , a little off topic but ...

I guess that is proof that YOU CAN make something that both sucks and blows at the same time!  :D

RCA, My Genset is located in my detached garage. The small percentage of RUG mixed in my fuel blend concerns me much less than
The straight Rug in the 5 gal gas cans I have in the garage, not to mention the 35 gallons in the tank of my truck. My push mower
holds more RUG than I use in a full tank of fuel in my car or my gen. My garage has typical roof and eve vents.

That said... I have no idea of your arrangement, so I am not suggesting that you (or anyone) take any risk's that may indanger anyone.

Murph, I have always shaken my premix also... And I share the seperation concern! So far... I have not experianced anything that
would indicate a problem. or I have not detected it yet!

Rob

Rob,

My diesel gensets and the fuel cache are both stored indoors in my workshop building which is worth as much as my house with all the tools and stuff accounted for.  I cannot afford a fire out there.  I'm not uncomfortable having a 5 gallon jerry can full of gasoline in the building, but I don't keep it anywhere near possible sources of heat or sparks.  My VW plant shares a small room in close proximity to a propane gas furnace.
It only gets straight diesel or diesel mixed with heavier oils for fuel.  I am planning a separate cinder block room for all the generators as soon as I can afford the materials.

According to the TDI Club website, yes I can get to the website and forums, just not the particular page with the fuel use diaphragm, the newer VW TDI engines need to run on unleaded diesel !   :D

Thanks.  Here is the BSFC map I was looking at:

http://pics.tdiclub.com/data/500/ALH_BSFC_map_with_power_hyperbolae.png


20HP at 1300 rpm might be ok.

Rob built a gen set with an older VW Rabbit engine. I believe they were rated at 58 hp peak.....
I think they would be a better choice and reliable its also a precup engine.

If you asked about 20 Hp of it at 1800 rpm I think that would be a very reliable alternative

Doug is right.  I put together a plant using a 1.5 litre, 4 cyl diesel IDI from a 1980 Rabbit.  I run it at 1800 RPM and it makes 9 kW of E, 3 kW from each of three phases.  I can not get any more power out of it at 1800 RPM so that suggests I am making about 18 HP.  My alternator is similar to an ST head but 3-phase and puts out 480 VAC.  I use a large xfmer to reduce this to 208 Y and 120 volts per leg.

I started out with a similar 1994 Jetta engine at 1.6 litres.  Unfortunately this engine had insufficient oil pressure and massive blowby, but in the short time I had it running it seemed to make slightly more power than the 1.5L.  Either of these engines would be a good choice for a generating plant. I have a 1992 Jetta with a 1.6 TD engine in like new shape having low hours since a rebuild.  I am thinking of using that as is as a drop in replacement.  The turbo will be effective at 1800 RPM and I think it will easily make 15 kW of E.

I managed to break an eyebrow shaped piece out of the thread that holds #4 injector in the 1.5 head.  For a time I ran the engine with 3 cylinders.  Noisy as a gattling gun with the air being forced in and out of that open injector hole.  The energy needed to make that noise caused the rack to be more open than on four cylinders and fuel economy went down as well as useable power. I have a mechanical speed regulator on this plant.  I didn't put more than a couple of hours on it in that mode.  It also vibrated a lot on 3 cylinders because of the imbalance of power strokes and the lights flickered horribly. I was lucky enough to be able to arc weld with stick, the broken off piece without removing the head and it now holds an injector once again and runs great.

I do not recommend shutting off any cylinders in a 4 cylinder VW diesel.  These engines are very economical, even with all four holes lit up.

When I do not need power from the engine for shop equipment but wish to continue running it for a bit of heat and light I wedge a piece of precut hardwood into the governor linkage to the rack.  It throttles the engine down to about 1200 RPM.  Even at this speed there is enough AC that the incandescent lights hooked up and the resistance heaters all continue to put out at a reduced rate.  Fuel use in this mode goes way down.  You can get about 2-3 kW at this speed (40-45 Hz) IIRC.

I like the VW engine in that it is very much quieter than the big singles I have.  I am leaning towards the singles though for any additional plants because they cost much less in parts and rebuild time when maintenance is required.  You can buy a Changfa 1115 for what the parts and machine work on the head will cost to rebuild a VW diesel.  You can buy a Changfa 195 for what an injection pump rebuild will cost for a VW diesel.

Looks like it is soon gonna be all over for those of us who try to be good people and responsible breeders, not overpopulating the planet and all.  Caution very depressing facts are presented in this video.  It won't be long before the earth returns to the dark middle ages.  Barbarism will only grow exponentially from here on.  We should all be so ashamed.  I am glad I won't be around to suffer the worst of it.

Other Fuels / Re: Hydraulic oil as fuel - anyone using it?

RCA,

Why not cut it with a bit of unleaded gasoline?

You might be surprised how well it works.

5 - 10% max should do it I would think.

Might be worth a shot...

Steve

Well I guess the experiment is worthwhile.  That said I have been trying not to add any RUG or anything else to my indoor stored and used fuel because of the fire hazard created when gasoline is introduced, even in small quantities.  Suddenly there is vapor pressure in the tanks and explosive vapors.

Hey Rcavictim,

Did you ever do a flash test on Hydraulic oil?

I just might have access to a never ending supply of it.

As for an actual flash test, I never did get a round tuit.  :(  I ended up with two hundred gallons of the stuff though.  It is about the vicosity of #30 strraight motor oil and has a sulfur smell to it.  This must be an EP additive to help reduce gearbox wear wherever this oil was suppossed to be used.  Either that or some differential gear lube oil got mixed with thin hydraulic oil and that is what I got.  Whatever it is, it does not burn very well in the diesel engine and makes very stinky, smoky exhaust.  I plan to use it as hydraulic oil in my loader, etc.

This is not to say that the hydraulic oil that you have access to won't make good diesel fuel.  Get some and try it!

Generators / Re: Splicing cable
« on: August 25, 2009, 03:29:14 PM »
Western Union splices is COMMON repair jobs on cut wires in TVs or blown up wires and sleeved with heat shrink tubing, depending on type of voltage/current, I double layer that.

But for stranded wire splicings I do this "method 1":

http://dodgeram.org/tech/repair/elect/splice.html

Gives most compact splice and neater with good practice, no sharp tips to poke or sharp edge.  West Union splice gave me bit of problems from time to time, that why I discovered this and found this works better.

Cheers, Wizard

I use this method in fig.4, also but for heavy, multi stranded power cables I add a step.  I wrap the joint tightly with a small gauge copper wire which pulls the loose strand package together tightly before I solder the joint.

General Discussion / Re: Bl**dy copper!
« on: August 25, 2009, 03:20:26 PM »

  One thing I will say is that I don't really like the 95/5 solder. It just does not flow nice! I prefer the old 50/50 stuff,50% tin and 50% lead. It flows nice with not an awfull amount of heat.

  I think 95/5 is 95% tin and 5% copper, A higher melting point

95-5 solder is 95% tin and 5% antimony.   I only use it (with paste flux) where I want a physically stronger/harder structural joint.  For regular copper plumbing you can't beat 50-50 or 60-40 wire solder.
