Domesticated the beast

[fabricator]

Based upon my limited knowledge of true India craftsmanship: I'll bet those groves resembling ACME threads were probably the result of some sort mangled drill bit, slowly turning, chewing, and gouging thread like groves into the metal as the operator forced this blunt object down through the flywheel. Now tell me that's not a plausible explanation for this sort of threaded holes in an India flywheel.   

That's a more likely explanation.

Here she is in her new home, got my wire pulled down to the battery bank, got the alternator mounted and belted to the roid.
It's new home is just down the wall from the bio diesel refinery.

OK!

Beautiful work; at least a click or two beyond my capacity.

I've read back through the thread and don't see the alternator specs.  Is an 8/1 a lot of engine for that unit?

And now that you've mentioned the BioDiesel plant are you going to let us see it?  Always looking for new approaches.

double click on the last picture and up pops a video!!!

The alternator is a basic Delco 33SI heavy duty, it's a rebuilt unit bought locally for 200 bux, the dream alternator would be a Leece Nevill but even a rebuilt is big bux, according to my calcs if I sack my batteries and the alternator has to put out 80 or so amps it will load the 8/1 pretty good, if you click on the picture it is a movie, the bio plant is in the movie.

Output wise the engine and the alternator might be well-matched, bu the alternator looks so small next to the 8/1! ;-)

It certainly does, that is the difference in 21st century technology and1 19th century technology, a new 8hp briggs will run that alternator and it's about the same size as the alternator, but the briggs will keep you busy hauling fuel.

Very nice setup all around. Impressive batch sizes for the BioD.

That alternator may hardly load the engine at all. Perhaps far too much engine for that job.
24 vdc X 80 amps is only 960 watts or .96kw
If we apply the rule of 2hp per kw of generated electricity we get an engine demand of 1.92 HP
May not even be enough to seat the rings properly ?

One way to bring things back into balance is to slow down the engine.

CURRENT SETUP:
=================
Assuming you have 23" flywheels:
23"flywheels / 2.75" alternator pulley = 8.36:1 ratio
650 engine rpm X 8.36 = 5434 alternator rpm

SLOWED DOWN
=================
450 rpm X 8.36 ratio = 3763 alternator rpm.
The alternator should still be able to put out the desired wattage, but the engine
will be running closer to it's new max. output of approx. 5HP

just a thought...

Veggie, I think you used 12 volts in your calcs.

At 28 volts and 80 amps you would get 2.24kw output.

The more I see the more I want to see.  So are you going to share with us what you burn in the heater part of your BioDiesel Plant?  The BioDiesel Plant?  Feeder stock?

Yep, that is the exact graph I used.

Sure, I am totally open source man LOL, that heater is a Korean war vintage universal utility liquid heater, mostly used for heating water for cooking and showers, it has a basic Beckett burner with a suntec pump, it basically flows the hot exaust gasses past an inner coil the over and outer coil, very efficient, I burn bio diesel in it, it'll heat 350 gallons to 140 degrees in about 10 minutes.
My feed stock is used fryer oil, we collect form about a dozen restaurants, I have a huge supply of centrifuged clean dry oil to run the roid on.
BTW, when I set up the bio plant I epoxied that section of floor, well, it turns out methanol, bio diesel, and potassium hydroxide will eventually break down epoxy paint, I mop down there so much almost all the epoxy is gone.

Thanks Bob,
You are correct. My error. 

Problem still remains....
So at the 2.24 kw charge rate the engine must make approx 4.48 HP.
1/2 load for this engine, and only while the bank is demanding 80 amps.
As the bank charges, the load on the engine drops until there is virtually non at all.
Not criticizing, I have the same dilemma with my system.
Solution was to add a diversion load in the form of an element to heat the water tank or space heater for the shop in winter.
In this case, perhaps the excess energy could be utilized to heat the biodiesel reactor to the desired 131 deg. F.
The idea being to keep the engine loaded enough to be efficient, burn clean, and not glaze up the cylinder.

That is pretty much what I have in mind, I already have a dump load for my turbine, I have a tank with four 2000 watt water heater elements in it, my turbine only uses one, so I can use another one to keep the roid loaded.

I have a question for you roid experts, my exaust tappet spins really good, my intake tappet hardly spins at all, how do you fix that?
