Listeroid Engines / Weight of 12/2 and ST 10 head?
« on: June 17, 2019, 12:59:29 AM »

If someone has the weights of a 12/2 and an ST10 gen head, could you please share that info here?
I could probably dig around and find it, but someone with that info handy will save a bit of time.

thank you

General Discussion / New posts in an email notification?

I don't specifically see any option to set email notifications for new posts.
Is that a feature on this forum? If it is, where do I set that?



Hi Folks,
Haven't  been on here in a long time, mostly due to depression from EPA ban on importing the engines.
I am wondering about the availability of castings and other more complicated? parts like camshafts, cranks, and injector
In addition to a fairly complete line up of machine tools, I recently acquired a Horizontal Boring Mill, and I think it will
give me the capability to machine the larger size castings associated with these engines.

My NEXT question is, is it legal to import the castings and parts, and build/ assemble,  and operate these engines in the USA?

Thanks for any insite and info, and please let me know if you might need machining services on your engine parts.

So I'm thinking again about the advantages/ disadvantages of a standard generator VS an induction generator as they apply to
reducing demand charges for my industrial 3 phase service.

It occurs to me that I have 2 choices with a standard generator:

1. Use it to power machines and the whole shop as far as the KW rating will go.
2. Use it only for base loads (lighting, boiler power, computer power,) and the stuff that's always a constant and known load.

Problem is, with the above loads, they will do little to affect my demand charges which increase based on what machinery I power up
during the course of the billing cycle. With industrial 3 phase service, the demand charges can be 50-70% of the total bill!
If I can't use a listeroid CHP setup to decrease my demand, there is no point to pursue it......which does not get me a Listeroid to play with, and therefore is not the fun result I am hoping for!   ;)

So.....question is.......with an INDUCTION generator, and using it to "push on the grid", and having it slow down the electric meter, that seems to be the way to reduce demand directly. 
Slowing the electric meter is the only way to incur less demand charges without having a generator big enough to handle the total
shop load. (Not practical, and too much power for a Listeroid solution)

Anyone here successfully running an induction generator and slowing the meter? Is this legal?
What hardware is required?  I have a 60 HP 3phase motor I could use as the induction generator.
Where can I read/ learn more about how to use a 3 phase motor as an induction generator? 
I am also considering the use of a WABCO air brake compressor off of a road tractor, belted to the Listeroid, to supply a certain amount of compressed air to the shop air system. These units are made to run continuously all day long, and load/unload as needed.
Most common sizes are in the 5-10 cfm range, which is not a lot of air, but could be helping to fill the air receivers on the electric compressors "all day long".  Why generate electricity -to run a motor....-to turn a compressor? Let the Listeroid turn the compressor directly and save conversion losses!
The Wabco units are water cooled, BUT they require oil pressure for lubrication, and I am not sure if the limited oil pressure from the listeroid oil system would be adequate........?

Induction Generator bad points:
1Down side to the I/G is that if the power goes out, it cannot (to my knowledge) be used as backup power.

And so goes the trade offs and dilemma....... ???

Appreciate your thoughts/ comments.....the battle for lower energy costs continues..... :'(


Waste Vegetable Oil / WVO blended with Diesel...in the same tank
« on: July 29, 2007, 11:56:10 PM »

I've read thru the posts here, but I'm not sure I've seen a specific answer to this question.
Rather than have a separate heated  WVO tank, is it possible to just filter it and blend it with low sulfur on-road diesel to run in a VW diesel?  What ratio is possible with no issues as far as thickening in the lines? I can get 5 to 10 gallons of WVO per month, and would rather just add a bit at a time
to the regular fuel tank......if possible.




Does anyone know of any available 20 to 50 HP single cylinder (or more) diesel engines for sale in the
Oil fields of Bradford, Oil City, etc. ??
I am interested in purchasing such an engine...

Straight Vegetable Oil / WVO source...too close...
« on: July 20, 2007, 01:19:46 AM »

Guys, I have been holding back.
The ice cream stand/ snack bar -across the road- had me suspect........
I HAD to ask yesterday.......

YES, they DO have a deep fryer.

Yes they DO shed 20-25 gallons of WVO EVERY week......

About 1000 feet from my shop.

I have run out of excuses!   :o :o

Listeroid Engines / "Kit engines".......where?
« on: November 27, 2006, 05:44:48 PM »

I've seen mention of 'kit' engines available......?
Can anybody direct me to the vendor?
I'm looking for a 2 cylinder listeroid.

Listeroid Engines / Lister w/ DI and Nat Gas fuel
« on: November 24, 2006, 03:58:28 AM »
Has anyone here experimented with using propane or Nat Gas as a primary fuel in a Listeroid?
I have seen it done with a VW Diesel in a lab. The Diesel injection is used to ignite the Nat Gas, but the engine runs mainly on Nat Gas, or somewhere upwards of 60% Gaseous fuel with 40% Diesel used for ignition and upper cylinder lubrication. 
Increased power with little or no additional noise, and some increased  temperature.

In my application, for the winter months, Natural Gas is most likely the lowest cost fuel I could use. (WVO is not free, and depending on what your time is worth, maybe not even cost effective).  My application would be to use Nat Gas to turn a generator before scavenging the heat for building heating. With no demand charges on Nat Gas (YET!) it makes sense to use the energy to turn a generator instead of sending it directly to a furnace.
I am in need of any information members might have regarding Gaseous fuel injection into a Listeroid engine.
The increased temperature might well be a plus for heat scavenging.

Any thoughts?   :-\

Listeroid Engines / Modern systems on old Lister designs
« on: January 01, 2006, 06:16:34 PM »
Ray Kurzweil was on C-Span this morning talking about modern technonlgy and how (among LOTS of other things) power generation will become decenteralized in the not-so-distant future. He's thinkin Solar. I' m thinkin Listeroids have their place in their
someplace too. At least till solar cells get super efficent and dirt cheap...


So brings up the topic:
Another aspect of Listeroid power I'm interested in, is the adaption of modern technology to the Listeroid design, which we all
agree is quite sound and may be a bit over-engineered.
Too much of that (modern technology) might have a reverse (and adverse) effect, but I think its good to at least toss ideas and theories around.

The typical and obvious have already been named:
Improved oiling/ filtering, synthetic oils, electric starters, glow plugs,etc.
Turbocharging and supercharging sound very interesting.
I wonder how economy could be improved by adapting a modern high pressure (possibly computer controlled) fuel injection system?
There certainly seems to be 'enough' iron and bearing area in the design to handle increased power output.
The tradeoff usually comes in decreased life and reliability, but with typical lifespans measured in decades, how much tradeoff is that really?  I am considering a power generation system that will have to be as efficient as possible, and also reliable and low maintence.
I am willing to break from tradition and employ any and all modern technology to the Lister design to achieve that goal.

Some gadgets I'd like to see evolve:

Low cost electronic govener (a kit or DIY plans would be great) 

Auto start/shutdown

Remote monitoring

Variable speed/variable load inverter generator,
(the engine speed can vary from idle to full depending on load,  but the frequency is maintained at 60cyc.
This is becoming more common in RV generators now)

Possibly all the above wrapped up in an EMS  (engine management system) 

Please post your thoughts ......

Listeroid Engines / Rising electric rates in upstate New York....help!
« on: December 26, 2005, 06:32:42 PM »
New to this forum, but have been looking at Listeroids and the idea of co-generation for a while now.  With the now increasing natural gas and electric prices, I am considering taking steps to build a system to provide
Elec. Power and heat for my machine shop.  Located in upstate New York,
our electric rates have been very high for years, and are getting rediculous
now.  With commercial 230V 3 phase plus the demand charges, I’ve been  paying  around .22 to .24 per KWH, and that is going up. On top of that, there is no demand charge if you're below 5KW total demand for a billing cycle, which I’m sure
I have been at times, but the bill always says at least 5.2 or 5.3 KW demand, so they can be sure to get the extra charges on it.
Demand charges ammount to between $75 and 150 per billing cycle.
I’m thinking 10KW would be enough capacity for present needs, and maybe 15 to 20 would be good for future expantion.  Our Natural Gas rates, although predicted to rise 25-35% have increased 80-100% on some peoples bills recently. There may be other people in these parts  interested in the ‘Listeroid solution’ also. I am familiar with Diesel engines, electricity, and mechanics, so I feel comfortable building and installing a system.

Some questions I have…..
Are there any importers near the east coast? Could I get a 12/2 – 24/2 withOUT paint on it? Are 3 phase generator heads available, or might it be a better idea to use a 3 phase motor as an induction generator? Are there any Listeroid enthausiasts in the Southern tier in the Rochester, Syracuse, Binghamton area?  I’d like to correspond with anyone that’s also interested
In this subject!
