Listeroid Engines / AC Motor as starter motor for a listerl(oid) ?
« on: November 10, 2024, 02:30:04 AM »
Has anyone used an AC electric motor as a starter for your Lister(oid) ?

If I put a 3" pulley on my 3/4HP, 1800 rpm 120 volt AC electric motor and belt drive to the 20" flywheel it would
theoretically turn the Listeroid at 268 rpm for starting. (20" flywheel / 3" Motor pulley = 6.7:1 ratio).
The challenge would be to kill the AC power to the motor as soon as the engine fires.
My concern is that the moment the engine starts and picks up speed it will overspeed the electric motor before the AC power is disengaged.
I am not so concerned about a momentary back feed but I do wonder if the motor would be damaged by any reverse currents?

This video appears to be using an AC electric motor as a starter. They show it at the 1:00 minute mark.
https://www.youtube.com/watch?v=SbqWkVC84bQ

And can a motor handle free spinning at 4000 rpm once the motor starts and speeds up to 626 rpm.
625 rpm engine X 6.7 ratio = 4187 rpm motor

Any advice or experiences with this method ?

Things I want to Buy / WANTED: Chinese Changfa style 175 or 180 Engine
« on: June 04, 2024, 07:12:53 PM »
Hi All,

I'm looking for a Changfa style R175 or R180 engine. (new or used is ok)
Preferably in Canada, but USA would work also.

Everything else / Current limiting device
« on: May 11, 2024, 03:37:22 AM »
Can anyone help me with a recommendation for a device that can limit DC current from a battery bank to a device?
In this case the 24 volt battery bank is connected to a 1000 watt grid tie inverter.
When connected, the inverter immediately draws the full 1000 rated watts and runs at it's maximum capacity (and heat) with no restrictions for longer life or safety.
My goal is to restrict the supply current to 800 watts (33.3 amps) by installing some device between the battery and the inverter.
For low wattage circuits a light bulb can sometimes suffice, but for 800 watts, I have no idea what would work.

If a big resistor is a possible solution, I need some help sizing it.

Any recommendations or instruction ?

thanks

Listeroid Engines / Lubrication port beside the decompression lever.
« on: December 25, 2023, 04:40:40 PM »
Question regarding the little oil plug right beside the decompression lever on Lister and Listeroid engines.
Is it an access port or a lubrication port?
When are we supposed to drip oil into that plug hole ?

It looks like it would lubricate the cam bushing, but isn't that bearing splash lubricated ?

The manual says nothing bout this port  ???

Generators / ST3 Noise and vibration
« on: December 06, 2023, 02:44:50 AM »
I spoke too soon when I installed my new ST3 head.
When I test ran the unit (unloaded) it was quiet and smooth.
Then I tested it with a balanced 240 volt ac load. Again smooth and quiet.
So I thought all was good.

Well ... today I tested it with a 1200 watt resistive space heater on one leg and only a 75 watt light on the other leg.
The growling and vibration was so bad that I thought something had broken in my system !
Terrible vibration every time I unbalanced the two legs, but just fine when the power is balanced.
A] Is this normal for an ST3 (do they need a balanced load all time) ?
B] Can it be fixed ??

Veggie

Here's some pictures.
The unit is wired for 230 volt and I am loading one leg more than the other when the vibrations and noise occurs.

Generators / Call for pictures and suggestions. New ST3 Install
« on: November 13, 2023, 03:50:22 AM »
Hi all,

I just installed a new ST-3 head that I had sitting in a crate for the last 10 years.
The wiring looked good and the windings are copper.
When I gave the system a test run (no load), the unit was surprisingly quiet compared to the 3600 rpm unit that I removed.
No screeching and electrical whining noises which both of my 3600 rpm heads made even when unloaded.

I now need to wire the head into my electrical system as two 120 volt outlets (one from each phase). That part is simple enough.
However, it is doubtful that the 4 open connections on the back of the junction box would pass north American electrical codes, so I'm
looking for ideas and pictures of what other members have done to re-wire, reconnect, or change the basic ST design,
Some people have replaced the metal box with a PVC "Scepter" j-box. Others use the stock metal j-box.

Please let me know what you did with yours, and send pictures if possible.
Here's what mine currently looks like....

General Discussion / Does anyone have a Changfa R175 or R180 PDF manual?
« on: September 05, 2023, 05:27:18 PM »
Hi all,

I lost my paper manual for the Changfa (or other chinese brand) R175 diesel.
Does anyone have a PDF version of this manual ?

Thanks

Changfa Engines / Need help with flywheel timing marks
« on: June 26, 2023, 10:00:41 PM »
Does anyone speak (or read) Manderin?
The flywheel on my Changfa 195 has 3 markings.
I would like to know what the markings mean so that I can confirm the injector timing.
The manual says to rotate the engine on the compression cycle until the "mark"  (does not say which mark) lines with the notch in the water hopper and that will equal the required 18 deg. BTC.

Well ... mine has 3 marks, and mine does not have a hopper cooler, it has a factory radiator with no notches or markings.  :-[

I have attached these pictures in case anyone can help identify the rotational degree values of these symbols.

Listeroid Engines / Listeroid Rocker Clearance Adjustmet Frequency (Too often)
« on: June 24, 2023, 07:31:45 PM »
Any one else having to adjust pushrod/rocker arm clearance seemingly too often ?
Mine seems to need clearances tightened up every 10 hours (Sometimes sooner ). I do keep the pushrod cups full of oil).
Possibly poor quality pushrod material ?

Generators / ST Generator Efficiency ?
« on: February 12, 2023, 06:28:37 PM »

Does anyone know what the average efficiency is for the ST style generators when running in the "sweet spot". The ST-3 in particular.
As I understand it, the newer design brushless 3600 rpm heads used on today's "screamers" are about 92%.
I was wondering if the ST heads fall in the same efficiency range.

Waste Motor Oil / Used Hydraulic Oil
« on: December 01, 2022, 04:05:11 PM »

Has anyone had any experience burning waste hydraulic oil (or a blend of gasoline and hydraulic)?
I came across a few forums where people said they were running it in their older diesel trucks.
I wondered if anyone has tried it in their stationary diesel.
Theoretically I would assume it's just a cleaner version of waste motor oil since there would be no combustion deposits or acid buildup.

Changfa Engines / New build - Changfa R175
« on: August 29, 2022, 08:33:21 PM »
New build almost finished.
A Changfa R175 coupled to a 4kw head.
(Max output is more like 2.5kw)

The unit has an external oil filter which added almost a liter to the oil capacity.
I suspect I can extend oil change intervals with this mod.
Also added is a throttle linear actuator which will allow future automation such as remote start/stop and throttle control.
You can see the actuator open the throttle just before the engine starts.
When the actuator is extended all the way to full stop, it sets the engine at 60hz speed. The max extension (60hz setting) is adjustable via a slotted mount at the back of the linear actuator

The small fuel tank is a temporary installation for testing purposes.
I only ran it for a few seconds because the cooling system has yet to be added.

Engines / Evaporative cooling question
« on: August 29, 2022, 08:25:27 PM »
On my latest project I was thinking of using and evaporative water tank for engine cooling. Just like the original Listers.
That project can be seen here ... https://listerengine.com/smf/index.php?topic=9572.msg109839#msg109839

While they do take a long time to heat up, once near boiling they keep the engine at the optimal operating temperature.
And warm up time can be controlled by the size of the tank.
I will most likely use a pump for circulation rather than rely on thermosyphon, although that simplicity appeals to me also.
My question to all those who use an evaporation tank:...

Do you mix glycol to the water in your systems ?
And if so, does the glycol boil off with the water or does the mixture get slightly more concentrated as steam leaves the system?
