Original Lister Cs Engines / Unpainted Flywheels
« on: April 05, 2020, 05:03:26 AM »

Curious,
I see many Lister CS engines with the outer face of the flywheel unpainted.
In fact some look like they were sanded, polished, and oiled.
Is there a reason for this? or is it maybe tradition. For an antique look ?

Sorry for the very late reply to to a comment made earlier in the thread,

mikenash stated:
Read my lips:  The fucking water is rising.  It's easy to measure.  Average annual rise last century was 1.4mm.

It's very easy to add cuss words and emotion to a statement in order to make it seem true and real.
The data that I have studied suggests otherwise.

Tide gauges all over the world are giving opposing trends. Florida shows some rising. Alaska shows the ocean level is falling.
Continental plates are moving all the time.
70% of the coastal major historical sites which once dotted the shorelines 3000 years ago are now under 70 ft (or more) of water due to natural rising levels resulting from glacier melt and tactonic plate movement.
We modern people think that we are somehow special compared to the hundreds of cities that have already been engulfed by natural sea rise in the past.
If man is dumb enough to build a city 4 ft. above sea level (most built in the 1600's or earlier before natural ocean rise was known) then they will succumb to the same fate as previous cities until the next ice age moves in and starts the cyclical drop in ocean levels.

Fort Denison in the Sydney harbor has one of the longest running tide gauge datasets in the world.
No remarkable sea rise is being recorded there.

This fellow seems to have had good luck with WMO

Straight Vegetable Oil / Re: injector

Good question,
A few years ago I sold 2 Listeroids to a fellow who had been running wvo for 5 years in an older Lister.
He experimented with all kinds of stuff and he told me that when I start running WVO in my Lister I should "lower" my pop pressure a little bit.
That did not make sense to me so I didn't do it.

WMO is a moving target. It's made up of all kinds of oils, additives, solvents and even anti-freeze.
The varying concentrations of these components means that every user will have a different base fuel to compare to others.
What works for one person may fail miserably for another even though the engines are prepared identically. Why, because the fuels are almost guaranteed to be different (even though they are both WMO).
If your oil is free from other contaminants and is non-synthetic, you may have good luck using it as a fuel if you clean it adequately.
Some people add 10% gasoline to reduce the viscosity.
Just for contrast, here are nominal flash points for various fuels and oils..

Flash Point Under Compression Ignition:
===============================
Diesel #1 ---100f
Diesel #2 ---125f
Kerosene ---150f
Biodiesel ---260f
Motor oil --- 450 f
Petroleum synthetics--- 485f
PAO Synthetics ---525f
Olafin Ester Synthetics ---725f

As you can see, the high end synthetics have a strong resistance to auto-ignition. (Diesel=100f vs. Olafin Synthetics=725f)
That's why synthetic oil works well in severe heat applications.
One can clearly see the massive difference in "burnability" (if that's a word ?) and how varying concentrations of these oils could drastically effect the combustion process.

Good info Glort, thanks  ;)

Straight Vegetable Oil / How long does WVO last ?

I have some WVO stored in a tote for 4 years now.
I does not smell bad or "painty".
It's de-watered and filtered before being stored.
Stored outdoors in the shade and it freezes every winter.
But I fear that this stuff must have a shelf life?  ???

What's your experience with the life of WVO ?

Maybe dieselgman south west of you.
Gary had many original Listers and clones in inventory.
Although he is getting out of the business, he many have some to liquidate.

Listeroid Engines / Re: What are you guys using for fuel tanks?

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.

I would suggest that the RA Lister company did extensive testing to find the optimal flywheel weight and diameter to balance the line between too much resistance to combustion acceleration vs. having enough inertia to carry good power through the next combustion cycle.

Would it make sense to use use variable resistors (dial pots)  for the upper/lower band setting?
That would allow the user to tune the system to the Array and Heating element.

Good catch hwew. I personally have only seen numbers in the 18 - 20 range.
(Except for the advanced computer controlled variable timing automotive diesel engines. VW, BMW, Merc)

So these engine are only running only 12 to 14 degrees advance according to that manual.
I would have thought they would run 18 to 20 like most diesels I am familiar with.
I suppose the short stroke has something to do with it.
It doesn't explain why they knock an hammer so much.

Glort, from your experience, where is a good zone to target in order to quiet them down?
Something like 9 to 11 degrees?

Agreed, very simplistic
