assistant: Craig,
 I doubt that this lashup would be "quite efficient" compared to an engine
more closely sized to the load. There's lots of friction loss in such
engines, and it would be quite significant at low RPM and load.
Think about engines like a Geo Metro or other mini-car. Run it at a
reasonable speed, and belt the alternator to also run at a reasonable speed.
I'd define "reasonable" to be the RPM that it runs when the donor auto is
doing maybe 45 MPH. Slower would get it way off the torque curve, and faster
just wouldn't be necessary for this application.
FWIW: I jacked up my VW Jetta Diesel and had a friend run it at 45 MPG in
high gear while I checked the engine speed with an electronic tach. It was
about 2200-2400 RPM, or about 50 RPM/MPH. Running the car at 67 MPH would
turn the engine at 3600 RPM; it sounds like it's really cranking at that
speed, but could easily operate like that for extended periods.
Running that Geo engine on natural gas and using the cooling water for heat
is eminently practical. Putting it into practice will "keep you out of the
bars and arms of loose women" for quite a while. (to coin a phrase)
Good luck!!

assistant: Was thinking that the rings could be changed to a different type.  Maybe
even put in lightweight valves with very light springs for "atmospheric"
intake much like a hit-and-miss.  With zero-gap rings such as some
racing engines use, it may not be bad.  I suspect it would be crucial
in ring selection.  Those zero-gap rings actually use an overlapping
end to approximate that...
It's more a matter of vibration.  I had a diesel Rabbit engine a few
years ago from a totalled car and was considering it for stationary
use.  Didn't seem the right one for it.  I want to get some fairly
large engine running very slowly.  Build the thing specifically for
the application.
Soundproofing would be a major trouble.  Making flexible hoses for the
fluids and exhaust, a spring-mounted subframe...  Ton of work there.
At slower speeds those problems drop dramatically.
Heh!  Have never had any problem keeping on the straight-and-narrow.
My wife would certainly help in that <g>.
Will do a "paper build" using a Chevy 350 to see if this could be done.
If a part isn't made for the 350, you don't need it. <g>.
Thanks!

Three HP should easily handle any auto alternator, an alternator delivering
80 amps at 12volts should need less than 1.5 shaft HP.
Which may mean that either the chosen rpm is unsuited, or the engine is worn
or off- tune. Then! there is the tendency of engine makers to lie about rated
HP!! ;-)
Real David and Goliath! I suppose you are not proposing that an auto
enerator
be the partner!! But could you easily find a suitable generator??
For co- generation I suppose you would deserve a Good Citizen award. Your

assistant: The Diesel Rabbit engine would be very efficient, but it won't make a lot of
difference if you want to use the waste heat in addition to the electricity,
and heat your house with it. And natural gas is the thing to use for fuel if
you have it available.
Good luck with your project.

an inverter.  U.S. Navy used to use batteries as back-up for the nav

generator.  This was, of course, superseded by a solid-state inverter.

assistant: Im looking at the Chevy 350 for a couple of reasons.  First, they are
*very* common, and parts are generally very inexpensive. Second,  I'd
rather lower the RPM and make up the power with torque.  The lower the
RPM, the less noise and vibration.
Probably wouldn't have much excess capacity.  Certainly not enough
to sell.  I don't want to be a major power exporter, but just about
break even on input vs. output.  Around here they buy power at about
half the selling rate.  I believe they even require a special
"ratcheting" meter so they can separate input from output and bill
accordingly.
Then again, this whole project may turn out to be economically
wrong.  But, it will be an interesting exercise!

assistant: I have located a 350 Chevy engine from a C60 truck.  It has the
heavy-duty parts, and a *very* heavy flywheel.  I think it has a
13" dual-disk Lipe clutch, or similar.   Before I buy any parts,
I intend to write to a number of folks who are known to do offbeat
engine projects.  It's entirely possible that someone, somewhere
has done this before.  No sense re-inventing the wheel...
Yes, I would intend on heating the house with the reject heat.
I wonder if a catalytic converter would work on natural gas?
The heat that throws off would be a bonus for very little loss.
I am looking at a V8 for a couple of other reasons.  An engine
with a larger number of cylinders is usually smoother.  And,
the V8 design is inherently balanced.  A four usually isn't.
There aren't too many engines with balance shafts for stationary
work.

assistant: On 08-11-97 Craig Healy wrote to Alec Cameron...
 Where is this information available, the bytes tha you are referring to?
 And what would be the cost of trying to do a project like this?
 Although, I don't think any fossil fuel is going to be the answer,
 however, I have made my living in the quest for it. Natural gas is
 probably always going to be the cleanest burning of all of the fossil
 fuels.  I am not sure how far they can go with cleaning up the way a
 diesel breaks its fuel down, there are limits I would imagine.
 I have always like diesel the best because of the amount of power it
 can produce, from the fuel it uses if it is used right, durability is
another
 factor.  A good propane or natural gas engine can have the same durability
 if it is optimized for their use and then run at the optimum speeds for
 torque and power.  I have seen big natural gas engines offshore, that
 are Catepillars that are actually diesel engines that are converted to use
 the natural gas that is available coming off of the wells that are producing
 on the platforms that they live on. Cat does the conversion on their own
 engines and are available as the same engine series but they start the model
 number with a big G instead of big D. There are several of the engine
 manufacturers of the big power plants who do this,Waukesau is another.
 They don't ever seem to wear out, they run for years and years.
 Most of the time 24 hours a day, while doing those years and years.
 Only emergencies or unusual conditions will cause a shut in on the gas
 compressors, and you surely don't want the generator to go down.<G>
 I enjoyed your post.

assistant: If you're not wanting to reinvent the wheel, you should probably copy what
others are doing along these very lines. They generally use small
water-cooled engines, 2, 3 or 4 cylinders. Use the induction motor to start
the thing, and use that for the electrical part of the co-generation. You
don't need a catalytic convertor; the engine will be pretty efficient because
it's running at a higher specific load than your V8 idea. You would probably
want a marine-type exhaust manifold to extract the heat from that area.
Vibration and noise are not a concern in these applications because it's
pretty straightforward to suppress. Put the engine on a concrete foundation,
with vibration-absorbing pads under it, and build a soundproof box around it.
You should be able to get it as quiet as a typical central A/C condensing
unit.

assistant: Craig,
 You can BUY these co-gen setups off-the-shelf. They tend to be a bit pricy,
but reportedly work quite well.
Look up back issues of Popular Science and Popular Mechanics; that's mostly
where I've seen the articles.
I also have a magazine lying around here that describes a York heat pump unit
that's powered by a natural-gas-fueled engine. It'll do the A/C for about
half of the cost of electricity in many areas, and runs nearly 130% efficient
during the heating cycle.
