Listeroid Engines / Students visit a "high tech " assembly plant
« on: January 08, 2019, 05:23:46 PM »

If you teach new students this type of manufacturing, you will get more of .... this type of manufacturing.

Other Fuels / Woodgas CHP System
« on: November 13, 2018, 11:07:09 PM »

This fellow did a really nice job on a CHP package. Makes lots of DC power plus usable heat... AND runs on wood.

Engines / Closed Loop Cooling (With Plate Exchanger)
« on: November 09, 2018, 05:11:13 AM »
Hi All,

I have a question...

My 2 cylinder Kubota generator project is almost complete.
I am now working on the cooling system.
My preference is to use a 30 plate heat exchanger that I have kicking around and run a loop from the engine to the plate-exchanger and back.
Then connect whatever I want to the other side of the exchanger to cool the engine water ( Fan/Radiator, floor loop, wall radiator, etc..)
Is it best to have an open (to atmosphere) system on the engine loop? or is it ok to run a closed sealed loop on the engine side?
I prefer to have it sealed so that  I don't need a reservoir/buffer tank, and I assume some type of expansion tank would be required like those used in hydronic heating systems.
Any thoughts, ideas, suggestions on this ?

The engine has it's own water pump and thermostat just like a car engine.

Changfa Engines / JD165 - First Run
« on: October 16, 2018, 11:32:51 PM »
Hi All,

I just finished my latest project.
A small JD165 air cooled diesel driving a little 2.3 KW head.
The engine makes 3.7HP @ 3000 rpm but I slowed it down to 2000 rpm.
The noise is a little more tolerable when the engine is not screaming.
Fully loaded I expect it to make approx. 1.5 KW which is ideal for powering a refrigerator, freezer, and some light in a outage.
These little engines use very little fuel.

Here is a link to the latest Fall release from Veggie Film Productions  ;D

PS: The exhaust pipe is temporary. I have not yet figured out a muffler arrangement.

Waste Vegetable Oil / WVO Centrifuge Design - thoughs ?
« on: June 18, 2018, 12:53:26 AM »
Hi All,

I have a design question as I fabricate a WVO cleaning centrifuge.
My initial design shown below incorporates a single tank with the "Fuge" mounted above.
The 26 liter tank will incorporate a sight level tube and a 1000 watt heating element.
The idea of the small tank is that I can process a Gerry Can at a time for small batches.
There will be a small gear pump mounted on the side of the tank which continually circulates the WVO
 up to the centrifuge where it gets cleaned and falls back to the tank.
Theoretically, the longer the unit runs, the more passes the WVO gets through the centrifuge.

Most users of this type of Fuge have a two tank system. One above which uses gravity to the feed the Fuge, and one below to collect the cleaned oil. Then they pump the cleaned back oil up to the original tank for another pass. This ensures 100% contact time for all the oil.

My Question:
After a lot of Youtube digging, I have not seen anyone use a single tank system like mine which makes me wonder...
Will ALL of the oil pass through the centrifuge 100% or will there be pockets of un-cleaned oil that never make the loops?
For me, the single tank system is a real space saver and I don't mind leaving the system running longer in order to get multiple passes though the fuge. But will ALL the oil get processed given a long enough run time?

Anyone with experience with this?

Cheers,
Veggie

Tank = 7 Gal (26 liter)

« on: March 26, 2018, 09:55:53 PM »
Hi All,

I have 2 Changfa flywheel stub shafts for sale.
I had extras made when fabricating for my own unit.
Allows for the mounting of a variety of pulley types and sizes. (See example)

To the best of my knowledge they fit CHANGFA (and Changfa style like Laydong, JianDong, etc...)
Model: 185, 190, and maybe the 195.

Check your dimensions:
Outside diameter: 5.75"
Bolt Hole Size:       0.5"
Bolt Circle:             4.79"
Shaft Diameter:     1.375"
Shaft Length:        3"

Price: $80.00 US plus shipping.

PM me if interested.

Generators / Any flicker when using a 3600 rpm head with a Roid ?
« on: December 05, 2017, 01:00:52 AM »
Hi All,

Is anyone running a house, shop, or backup power using a 3600 rpm head with a 550 - 650 rpm lister(oid) ?
I am wondering about flicker (or lack of it).
Intuitively it seems that flicker may be reduced or even eliminated when spinning a head at higher speeds.
I am thinking of swapping an 1800 rpm ST5 head for a 3600 rpm 4kw head... and flicker elimination would be a bonus. ::)
Does it make any difference ?

Engines / Fuel Rack Solenoid connection Question
« on: November 28, 2017, 03:08:44 PM »
Hi All,

I have a fuel rack solenoid that I wish to mount on the Listeroid as a shutdown device.
This was an "ebay special" and came with no manual or wiring directions.
The [PLUS] and [MINUS] terminals are obvious but it also has an [aux.] connection.

Can anyone tell me what this terminal is for and whether I need to connect to it?

cheers,
Veggie

Changfa 180 Head Gaskets:

If anyone has a Chinese Changfa style 180 engine and would like some spare head gaskets for when you de-carbon, I have 2 for sale.
These are the higher quality aftermarket items with the silicon water jacket port seals.
I have two for sale.
$10 each  (Plus mail)

Generators / ST Wavfeform question
« on: May 02, 2017, 03:59:32 PM »
Hi all,

I have been digging around the older posts but I could not find an answer to this question...
I have an ST-2  2kw head that I was thinking of using on a small project.
I am wondering what is the typical quality of an ST waveform ?
Are they usually OK?  Perhaps rated as "average".?
I would assume that this is something that is "built-in" to the winding quality and cannot be adjusted if there is a distorted wave?
(I do not own an oscilloscope)

My other option on this project is to use a Voltmaster 3600 rpm brushless unit which is typically a very good generator, however given the choice I would prefer an 1800 rpm ST.

What's your experience?

General Discussion / Ice Storm and outages
« on: January 29, 2017, 01:06:46 AM »

The Ice Storm in the Maritimes of Canada has knocked out power to 54,000 homes and killed several people.
Good luck to any members who are weathering this storm.   ;)

Stumbled on this video and wanted to share it...
Lovely old Lister engine working relentlessly in a desert field pumping water from a Well.
Beautiful !
