Original Lister Cs Engines / Re: Big funny piston rings
« on: March 29, 2020, 08:04:43 PM »
I've seen piston rings doubled up, much like the Total Seal rings. That generally does not work all that well, but it can work.

Generators / Re: Lister Flicker

I know of an off grid setup like this. They first used a propane powered generator to charge the battery bank, which wore out the propane genset. They then switched to the 2 cylinder listeroid. As you might expect, there are substantial losses when using AC power from a generator, into a charger, into a battery, out of a battery, into an inverter and end consumer. From what I was led to believe, the fuel consumption went up by about 30% when charging the battery bank/inverter setup vs. using the listeroid power directly.

Put another way, they discovered it was clearly most efficient to use a modern high quality, low fuel consumption diesel generator, and directly power the multi dwelling off grid compound. The Listeroid was not as efficient as a modern diesel genset.

Eventually, they chose a set of tracking solar panels to charge an upgraded battery bank and have not looked back. They simply use the high power consumers during the day when the sun is shining.

EDIT: It's generally said that a Listeroid consumes 0.125 gallons of fuel per KWH. Modern diesel generators consume 0.09 gallons of fuel per KWH. Typical modern diesel gensets are about 28-30% more efficient than a listeroid.

I've said this before, but the real advantage to the Listeroid is the 6/1 and operating it in the middle of it's operational output, consuming a gallon every 6 hours. Modern stuff is not sized to run in that operational range and will therefore consume much more fuel when making 1500W.

Listeroid Engines / Re: What are you guys using for fuel tanks?
« on: March 18, 2020, 06:51:36 PM »
I use an oil reservoir used on hydraulic systems. Available in many sizes.
They are available in many shops and have the fill/drain ports already in place.

Stunningly nice!!!

I neglected to mention that both units are semi-portable. The 6/1 is on tires, the the 20/2 is on the steel pulleys, used as wheels, that came with the engines.

Listeroid Engines / What are you guys using for fuel tanks?
« on: March 17, 2020, 02:38:47 PM »
I have a 6/1 and a 20/2.

What kind of fuel tank setup do you have?

My 6/1 uses the original green tank that is mounted on the head. While it seems big enough (not sure of the capacity) it is rusting badly inside. The 20/2 uses a 6 gallon outboard engine fuel tank and that seems to be a good choice. But the fuel lines are getting stiff.

I'm considering welding up an aluminum tank to mount on the 6/1. One that holds about 5 gallons, so the thing can run all day without stopping. Also would like a large filler opening, so I can get my hand in there and clean it out.

Thoughts?

Listeroid Engines / Re: Catalytic converter to reduce exhaust odor
« on: March 08, 2020, 06:15:00 PM »
I ordered the following diesel catalytic converter, with a metallic substrate. The metallic version is supposed to be a bit more robust and much lower restriction. I hope it shows up as the part may be obsolete. If this works out, I may purchase a larger unit for my 20/2 Listeroid. It should make the engine a touch quieter too. Although, I use an automotive muffler and it's pretty quiet.

"Magnaflow 53004DM_Metallic Substrate Diesel Catalytic Converter"


EDIT: Foiled! Order cancelled by vendor. Ugh. The search continues.

Personally I think your barking up the wrong tree, engine timing, dirty air filter, worn injector needle or incorrect pop off pressure would allow excessive fuel into the cylinder.

Thanks, but I'm aware of the above. The engine runs cleanly, with invisible exhaust. The problem is that I'm very sensitive to it.

Case in point, my Jetta TDI developed a small leak at the EGR cooler shaft seal and I couldn't stand driving it. I'm that sensitive to it. That's a clean engine with modern controls too.

Any thoughts on where I can find a cheap diesel catalyst that is "real". I can't imagine the $90 diesel catalysts on ebay have any precious metals in them.

Are you really sure you want to try this.

Catalyst poisoning refers to the partial or total deactivation of a catalyst by a chemical compound..

Sure, I'm willing to try it, as long as the cost is reasonable.

My 6/1 under load, gets the exhaust pipe all the way up to about 330F ( 165C ) and I suppose the gas is a little bit hotter than that, but I don't have much hope that it will fire off a 200C cat.  But try it if you got the parts

That seems to be on the low side. I recall seeing 450 F with a non contact thermometer. Remember, you must paint the pipe black to get a really accurate reading.

Even so, you may very well be right, the lister exhaust may not have enough temperature to light off a Diesel catalyst when running at lower loads.

  - [Jet-A] does it have enough lubricity to prevent your fuel pump from seizing? Also burning Jet-A smells a lot like a diesel...

In a past life, my late friend (Rocketboy, Bob Gross) , along with Horsepoor, and I brought home 5500 gallons of Jet-A (along with other fuels and oils) . We purchased diesel vehicles/motorhomes and so on, then ran them on Jet-A only after HFRR (high frequency reciprocating rig) testing the fuel for lubricity. I think I've posted about this in the past. By memory:

Jet-A had an HFRR wear scar of 650 or so,
Adding Stanadyne lubricity additive brought the numbers down some,
A combo of Stanadyne and 200 to 1 TCW-3 two stroke oil lowered the numbers to 255. Well below the 450 requirement for diesel.
Note: lower is better

I also have an Alfa Laval centrifugal filter that cleans the fuel of any moisture and particulates. Fuel comes out crystal clear.

So, on every batch of Jet-A, we add some TCW-3 and Stanadyne lubricity additive. None of us have experienced any problems with the fuel.



Burning Jet-A in a diesel engine smells exactly like burning diesel fuel. A characteristic stench that I find objectionable.

I am going to give it a try. There are diesel specific catalysts that light off at 200 deg C. It should work. Maybe I can find one from a VW.

Thanks all. I work in the aviation industry, so I have quite a supply of Jet-A. Currently about 500 gallons.

Listeroid Engines / Catalytic converter to reduce exhaust odor
« on: February 27, 2020, 02:29:20 PM »
I have 2 Listeroids, a 6/1 that's cranked up to a 7.5/1 by raising the RPM and a 20/2 that's slowed down a bit. Both engines have automotive mufflers and are quiet enough for my location. However, I absolutely despise the smell of diesel exhaust and while both engines have clear exhaust when operating, they do have enough odor to be bothersome.

Years ago, I remember some effort was being made to develop an emissions compliant Listeroid. That's not my goal here.

What I've been thinking about is purchasing a diesel specific catalytic converter and mounting it as close to the head as possible. I have TIG welding equipment and it would be quite easy to weld a flange that installs it directly on the head. Yes, I know most diesel owners desire to "delete" the emissions equipment. However, I have sufficient power, and I'm sure any HP loss would be minimal with a low restriction catalyst.

What I'm not sure about is whether it would help, and whether or not it would actually "light off" and function.

Has anyone done such a thing?

Listeroid Engines / Re: another disaster: silver gunk in new oil
« on: January 23, 2020, 01:29:55 PM »
I think it is fuel maybe because running a cold engine. Or just blowby.
Vegitable oil can give nice gunk.
Regards bernhard.

are you suggesting that my fuel - my used vegetable oil - is getting into the engine cavity and turning silver and gunking up the motor oil?   That doesn't seem to possible to me. 

WVO can cause motor oil to polymerize. I'm not sure if that is what's happening here.

Yes, both fuel and combustion byproducts get past the rings in large quantities. That is in fact what makes the oil black. Air compressor oil stays clean nearly forever.

It's fantastic that we've been able to offset our total energy consumption by just over 2% using wind and solar.

Remember, the electric grid is only about a third of national energy consumption. Automobiles make up 16%.

An enormous quantity of energy goes towards heating homes and businesses. Wind and solar simply can't do that, it can't even make a dent.
