Changfa Engines / Chang-chai and ST head, deal? Or no deal?
« on: October 27, 2021, 11:13:01 PM »

It ain't pretty...
Found this, seller was asking $600 said he'd take $550. I saw it run, started right up with the electric starter.
He knows nothing about the ST head, wires are disconnected. Data tag is unreadable except for 2000 which may
be the year built. Is there a stamped model/ serial number someplace?

Worth the money?

Anything for Youtube views I guess..... :(

Listeroid Engines / 6/1-8/1 650 VS 850 RPM and Iron VS Alu. pistons
« on: October 26, 2020, 03:55:22 PM »

I've seen the warnings "do not exceed 650 RPM with a cast iron piston", or "if you're intending to run 850 rpm, better have an aluminum piston fitted"....etc.
Could someone please explain this requirement in detail?

Anyone on this forum running their Lister-or-roid on the west coast due to power outage?
I suspect if they were, they'd have already posted here

Indian 'craftsman' working on a 6/1
This one's special, several 'tool tricks' shown in the video as well.

OK, I skipped along thru the horror movie. I see now what this really is. It's a motivational video for all newbies that might be afraid of doing something terribly wrong to their engines. If THESE guys can take one apart, and have it running at the end of the movie, ANY one can do better than this, and expect better results.

Listeroid Engines / Excited soon-to-be caretaker.....
« on: June 20, 2019, 10:22:41 PM »
Just wanted to express my enthusiasm as a soon-to-be owner of a Ashwamegh 6/1 and a Metro 12/2.
I've been mostly a lurker here for probably 12-14 years and never thought I'd be able to actually own a Listeroid, so very excited about
this. The 6/1 has never been run, and the 12/2 has less than 2 hours of no-load run time.
Totally new to these engines, and will have questions for the forum. Any and all advice eagerly accepted.


Thanks
Dan

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?
« on: February 06, 2018, 03:38:01 AM »

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?

thanks

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
pumps.
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.

thanks
