Listeroid Engines / Re: Hot Water Circulator Max Temp Rating.
« on: May 30, 2024, 05:10:33 PM »
I ended up using an automotive 12V fan, and a 12V power supply plugged into the gen output. Works like a champ on my 20/2. My 6/1 has a Honda Gold Wing radiator and fan assy. It's also powered by a 12V power supply.

Marlinpjones.com is a good place to search for surplus power supplies.

Listeroid Engines / Re: Vibration Sensor prevents Flywheel launch

Thanks,

When I move to TN, from FL, I will probably mount the twin properly in my shop (on helicopter blade bushings) and make it the standby powerplant. A nice flywheel cover is absolutely in order. I was thinking of using simple EMT tubing from Homeless Depot, and bending it to shape. Welding it up and attaching metal screen, such as a robust hardware cloth.

The single listeroid is on a wheeled cart, and can be pulled around easily, so that one stays like it is.

I just retired and while the listeroids are not a priority, I will spend some time buffing them up. The safety aspect becomes ever more important as we age.

That is one of the best stories I've read on here. Congrats for getting the safety systems right!

I don't use any safety systems on my engine, but it is probably time I do.

Lister Based Generators / Re: Time for generators

OK, I'm totally impressed!

The lithium iron batteries generally are no more risky than lead-acid. I don't want to say they can't overheat, as any battery can overheat. But the electrolyte is not flammable in the same way as Lithium Ion.

If not already considered, using a spring and cable assy to tension the fuel linkage can functionally eliminate all play.

Cool setup and thanks for the pics. It's really nice to see what people are doing. Can you run your solar setup off grid?

That is truly amazing work!!!

Any chance for a video of it running?

Mine sounds like that from time to time. In my case, a spray of belt dressing quiets it right down.

Original Lister Cs Engines / Re: Bigger engine to replace st3 engine

I am unfamiliar with the air cooled Lister engines. Can the OP provide a pic? Might be interesting to see the setup.

Listeroid Engines / Re: How To Choose A Radiator

The same heavy loadings that kill the upper shell in an 8/1 or SOM flywheel engine can be duplicated in a spoke flywheel 5 or 6/1 engine by having the injection timing advanced from the Lister specifications.

Correct, injection timing is critical for bearing life.

I recall your very nice builds and frequent participation.
Re the Youtube link..... A really nicely done and well balanced movable system. Didn't you use a helicopter rotor balancing system to smooth it out?
Is it still in operation?
Does that engine use a water pump? Cheers Hugh

Yes, the engine still works great. I need to make a new fuel tank. Thinking of an integral sight glass.
Yes, the setup uses my preferred method of circulation. A brand name "Grundfos" 120V water pump. Generally the style for hot water circulation for home heating.
Yes, I use an ACES helicopter/jet engine balancer to balance the engines. It can also be done "by hand, by feel" if you know how. I put some of the clues in an old thread.

  were you one of the original fella's to make the hollow oil dippers ? I know xyzer was one as well. Was wondering if you have them installed in your engines?   

I do have the XYZer hollow dippers. So far, they are holding up. I did not make my own.

Listeroid Engines / Re: Whete to find non detergent oil in canada
« on: February 17, 2024, 01:25:38 PM »
I really can't think of an advantage to a Non Detergent oil. Modern diesel oils are very well suited for Listeroid use.

Listeroid Engines / Re: Knocking, now what?
« on: February 17, 2024, 01:24:12 PM »
I'd love to see a video of it up and running again.

These engines really are special. With basic skills, they can be kept running nearly forever. Good job on the repair!!!!

That is AMAZING.

Do you have any pictures of inside the cylinder? I would love to see how it is configured.

Generators / Re: ST Generator Efficiency ?
« on: January 14, 2024, 04:17:15 PM »
It has been quite some time since I've done these calculations, so everything is by memory. However, being rather nerdy, I do tend to like playing with numbers.

My 20/2 Listeroid is run at 850 instead of 1000 RPM. It's well tuned and makes about 18HP. It will produce 11,500W with the ST15 head. The generator head efficiency seems to be about 85% at this point in it's operational range, about 76% of rated max output. I am not using the Z winding, instead I'm regulating and filtering the output of one 120V leg, in an attempt at producing a smoother sine wave.

In the end, the generator head is not terrible. But the power pulses of the engine do result in the typical lister flicker.
