Listeroid Engines / Exhaust gas temperatures - 3kwListeroid
« on: February 18, 2013, 02:36:22 AM »
Today I made the necessary adjustment to speed up my Listeroid and increase the kW out of the system for service as an emergency generator instead of a 450 rpm battery charger.

The changes involved...
1] Installing the correct generator pulley for 750 rpm operation.
2] Changing the governor spring to the stock 750 rpm version.
3] Slightly advancing the timing (it was retarded for slow speed operation and knock reduction).

For slow speed operation (450 rpm) I retarded the timing by screwing-in the IP lifter tappet by 1.5 turns.
Today, I backed out the tappet by 3/4 of a turn.
Not back to the factory setting, but just enough to advance the timing and still give significant knock reduction.

My question:
Does a few degrees of timing substantially effect the exhaust gas temperature (EGT) ?
The reason I ask is that after running the engine for an hour at full load (3kw) I noticed the hi temp silicone tape was burned off the first exhaust joint.
This tape has been on for many hours and has never showed any signs of heat stress.
I am trying to figure out which one caused the higher EGT's...

A] The timing retarded by 3/4 of a turn from factory stock ?
B] Or just the fact that I am now pulling full load 3kw (6hp) from the engine instead of 2kw (4hp) ?

Any ideas ?

Oh...and.... what's the normal full load EGT temperature on a Listeroid     anyone bothered to measure that ?

Listeroid Engines / Flywheel Placement - 6/1
« on: January 07, 2013, 05:02:55 PM »

I am planning to move the flywheels further away from the engine on my 6/1 Listeroid.
Are there any guidelines or limits on how far these can be moved?
Currently there is approx. 1/2" between the flywheel hubs and the engine.
I am proposing to slide to flywheels 4" away from the engine to accommodate the mounting of pulleys.
Anyone done this (or even more than 4") ?

thanks,
veggie

Engines / Gasket Material - Exhaust Port
« on: November 18, 2012, 11:04:29 PM »
Hi All,

When I removed the exhaust flange from the head of my Changfa, the gasket came off in two pieces    :(
It's the type where a metal gasket is sandwiched between two paper (or asbestose) gaskets to make one piece.
There is no way I will be able to find a local replacement.
Part of the paper stuck to the flange and the rest (including the metal inner) stayed on the head.

Do I need a metal core gasket to replace it ? or is there a good non-metallic gasket that can be used for exhaust connections ?

thanks

Bio-diesel Fuel / Seed Press - for Biodiesel
« on: September 29, 2012, 04:17:56 AM »

*** SOLD ***

Hi Everyone,

I have a 1to2 ton/day seed press for sale.
Still in the crate.
If any farm owners or biodiesel enthusiasts are interested in a mid-sized oil press

The unit is priced considerably lower than you would find from equipment suppliers who carry this product.
Drop me a PM if interested.

cheers,
veggie

PS: I posted the offer here because the "for sale" section seems to be focused on Lister and I didn't want to mix things up.
     Moderator, please drop me a line if you would like this message moved to another section.

Generators / ST Generator head load limits
« on: September 11, 2012, 09:44:12 PM »
Has anyone taken an ST head above it's rating ?

Part 1:
I am wondering if the ST types have a service factor.
Some heads state a "rated" wattage and an intermittent "peak" wattage (eg: 4000/4800)
Does an ST-5 burn up at 5.1 kw's ?

Part2:
Can an ST head operate continuous at it's rating ? (eg: ST-5 running continuous at 5kw)

cheers,

Listeroid Engines / Unusually loud Knocking - Help
« on: May 04, 2012, 05:13:15 AM »
Hi All,

I have been experimenting with various speeds to run my listeroid for two reasons.
1] Sound control in a residential neighborhood
2] I only need a maximum of 800 to 1000 watts to charge a battery bank for 2-3 hrs. each day.
    ( 55 amps X 12 volts = 660 watts + 20% for losses = 792 watts )

I have been swapping pulleys and belt combinations to get 1000 watts of power when fully loaded and at a reasonably low speed.
The magic speed for the engine/generator seems to be 465 rpm.
The system has gone very quiet EXCEPT FOR THE DIESEL KNOCK !   Angry    It stayed.
Wow ! the ignition sounds like a guy hammering on an anvil with a sledge hammer.

I don't think I'm anywhere close to the point where the engine is in a hammer/detonation mode.
Many other members have run at speeds lower than this.

My question to everyone is in regards to injector timing and injector spring setting.

A] When I first got the engine 2 years ago, the Lovson factory suggested I loosen the injector spring screw by 1/2 turn if I wish to run the engine slower. Does this make sense ?

B] And what about injector timing. Has anyone been able to control knock by retarding the timing ?

cheers,
veggie

FIRST SMOKE (again)

Got my little LR1 running today after a long dormancy and a trip from the UK to North America.
Thanks to TimSR2 for the pointers on bleeding the fuel system.  ;)

Runs like a champ !
First run....

Listeroid Engines / GM90 Listeroid Powerplant Walk-around
« on: January 06, 2012, 03:59:18 AM »
Hi All,

For those who have not already seen this.....
The holidays allowed me a bit of free time to finish up my Listeroid powerplant project.
After a year of "on-and-off" attention, this project is finally done.
Rather than explain my setup, I made a "walkaround" video of the unit.
This is a GM90 Listeroid coupled to a Voltmaster 4kw head.
Currently the engine is de-rated from 900 rpm to 650 rpm where it produces 5HP (or 2.5 kw electrical @ full loaded).
I did try to coax 3kw from it but the black smoke told me it was too much.  ;D

Later, I may change the sheaves and run it at 900 rpm to get the full 8HP and 4kws of power.

Hi All,

I finally found an LD1 and joined the ragtag fugitive gang of Lister owners !  ;D

Can anyone help me determine the year that my engine was made?
Serial number is: 643LR118

***GM90 HEAD GASKETS***

Hi everyone,

I have been working with John to produce a gasket for us GM90 users.
I sent a GM90 head gasket to John at "Gaskets to Go" and a gasket is now available for the 6hp and 8hp GM90 models.

John is making the gasket available via an Ebay page here.....

I have tried the gasket myself and I am happy with the results,

Waste Motor Oil / WMO and combustion variances
« on: February 01, 2011, 04:42:27 AM »
As I see it, the reason why we will always see test results that are all over the map is because there is no standard for the fuel.

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).

Here's a chunk of text from a post I did last year when investigating the burning of synthetic oils and why some oils burn better than others.

Just for contrast, here are nominal flash points for various fuels and oils..

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 autoignition


One can clearly see the massive difference in "burnability" (if thats a word ?) and how varying concentrations of these oils could drastically effect the combustion process.

One person may report lots of carbon, another may report excessive ash, while another person may have very clean burning.

IMHO...for this reason, it's a waste of time trying to compare one person's experience with WMO to your own.
Chances are, no two fuels will ever be alike.

Let's everyone share your findings with WVO and it's filtration and preparation, but let's also accept that your personal findings may vary greatly from what others post.
