Everything else / Bad Solar Panel
« on: September 15, 2021, 03:55:17 AM »

So, I just installed 4 x 220 watt solar panels on a rack mount system.
Somebody at the factory plugged the male and female MC-4 cables together on one of the panels.
When I took the panels out of their cardboard box on my lawn, it was a bright sunny day. Before I noticed that the one panel
was shorted out, it was too late.
3 panels put out 35 volts, 1 panel puts out ZERO.

Question.
Is this panel ruined? or is it possible that it could be repaired by opening the j-box and replacing diodes ?
At this point I have not done anything due to time constraints.

   CUSTOM ST-5 LISTER(OID) SERPENTINE PULLEY

This is a custom machined pulley for an 1800 rpm generator head.
When coupled to a Listeroid with the standard 23" flywheels, it provides the correct ratio
to drive the generator head at 1800 rpm.
It uses a standard automotive flat surpentine belt.

It also comes with a 38mm shaft bushing to match with the shaft of an ST-5 generator head.
Solid steel. Weighs about 15 lbs
Price: $135 CAD

Can ship anywhere in Canada at owners expense.
Send me a PM if interested

Lister Market Place (things for Sale) / ST-5 5KW Generator Head FOR SALE
« on: August 15, 2021, 03:42:55 AM »
  Power Solutions ST-5

I have a "POWER SOLUTIONS" ST-5 head for sale.  1800 RPM, 5KW max rated.
This is the version that was imported by John Fergusen in Ontario and modified with better quality bearings.
John also removed the stock junction box and replaced it with an approved version.
He then got the units Canadian [ETL] rated.

This particular unit has approx. 5 hours use.
It was assembled with a Listeroid CS6, and then promptly disassembled when a friend of mine bought the engine.
The ST-5 has been in storage since (4 years).
 
Price: $ 450 CAD  (Considerably less than I paid for it)
I can ship anywhere in CANADA at the buyers expense.

PM me if interested,

For anyone interested in going down this road, here is a documented lab test with interesting recommendations.

Hi All,

Is anyone familiar with the internals of the Injector Pump and whether modifications can be made to the minimum flow point?

I have a project where I would like the engine to run continuous at 250 rpm.
The problem is that when the speed is set any lower than 325 rpm, it cuts out !!!
The governor linkage is quite free and I have tried several springs ranging from stiff to very soft.
Even using my hand on the rack plunger I can control the speed closely down to 325 rpm and the engine stops at any point below that.

I prepared a video to demonstrate.
You will note that as the engine speed hits the current setting (325 rpm) it cuts out, then as it slows below the set point the governor gives a small tug and the engine fires with a thump to bring it back to 325. Then the injector pump stops fuel flow and the same cycle repeats. You will hear a thump every several revolutions as the engine fires and then cuts out to coast again.

I have seen many engines running at very low speeds. So I know it's possible.
Such as this one...

Any ideas for modifications ???

Everything else / Generator Enclosures
« on: April 10, 2021, 04:29:40 PM »
Has anyone enclosed a diesel generator for noise attenuation ?
I intend to surround my R175 Changfa with an close fitting insulated enclosure to really silence the system along with the new "dual tank" muffler.
My fear is that the generator head will overheat. It's a 4KW head which will be loaded to 1.5kw continuous.
If I run a cooling duct to the inlet of the generator fan it would create a massive channel for noise to escape.
How did you get around this issue?

Or ... maybe it's not an issue at all ?

Listeroid Engines / Lister Muffler Project
« on: April 03, 2021, 03:38:07 PM »
Some have had adequate noise reduction using a 25 lb propane bottle.
The idea I wanted to try was to have 2 bottles in series creating a first stage expansion, and then a second stage expansion.
I purchased two 5 gallon portable air compressor tanks and with the help of a welder friend, added a few threaded ports so that the two tanks could be screwed together.
Also added were 2 threaded ports for inlet and outlet.
The outlet port is oriented to allow a vertical stack to be added.

Below are pictures during construction....

Here are two videos of the tests that I ran.
I must point out that in both cases there is also an automotive muffler at the engine (which are almost useless on their own).

First is a test with the listeroid. I did this test before finishing and painting the unit in case it was a failure.
It turns out that the muffler did a fine job of almost eliminating the noise. (Neighbours cannot hear it)

Second test was after the unit was completed and connected to a changfa engine running at 1150 rpm.
You will note that the engine is mechanically loud indoors, but outside the muffler is extremely effective.

Generators / Axial Flux Generator Search
« on: January 30, 2021, 12:45:21 AM »

Anyone know of a supplier of Axial Flux generator kits or parts?
Or has anyone built one ?
I have seen DIY plans on how to build them but making my own windings and epoxying everything into a functioning unit it a bit more that I want to tackle.
I thought there were windmill DIY companies who catered to building these, but perhaps many of them have dropped away.
Imagine one on the flywheel of a Lister !  ;)

Changfa Engines / Chagfa 175 CHP unit - First Test
« on: January 04, 2021, 08:24:48 PM »
Here's the first test of the new Changfa R175 CHP unit.

Gave me something to do during lockdowns   ;)

Some features/changes to the original engine.
- Larger and better quality air filter
- Machined an adapter to divert oil from the internal screen to an external filter.
  (This increases the oil capacity by almost 1 litre)
- Removed the hopper cooling system and replaced it with a pump driven closed circuit
  loop which passes through a flat plate heat exchanger allowing heat to be removed to a useful application.
- Installed a lighter throttle lever spring which seems to allow the governor to be more sensitive at the lower rpm.

The unit is currently designed to run continuous at 1100 rpm. In this test it is loaded to 900 watts with an electric heater.
At 1500 watts the engine bogs down so I suspect the 900 watt load is approximately 85% of full load.
