Other Slow Speed Diesels / Re: Bamfords shop work

Very nice job on that Bramford.
Great to see that they still have a use.
It should last a long time running at 600 rpm.

On my GTC 6/1 Listeroid, I was able to remove the COV and screw in a plug provided by Central Georgia Generator. (back 10 years ago).
The plug was fitted with a glow plug for cold weather starting. Sold it along with the engine several years back

Where did you find a Chinese copy of a Kubota.?
Are they still available ?

Yes, it is certainly do-able.
If I had a EV then this is how I would charge it....

The efficiency of the energy conversion is not so important since you say that you have an endless supply of free WVO.
Just do it !   ;)

Wow! Sorry to hear about your fire and the ensuing damage.
Good luck with the rebuild.

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.

Thanks Bob, I realize that these units are not the best solution for this job. Idea cancelled !!
I found some 24 and 48 volt DC power supplies that may work much better and with greater efficiency.
(120VAC to 24DC @ 50 amps) I can drive the power supply directly from the generator 120VAC outlet.

Can anyone shed some light on the principle of operation for these little units.
Here's the description from the Ebay advert....
(Translation is not the best)

Model: 3500 (belt type)
Rated speed: 2800-4000 rpm/min
Voltage: 220V
Power: 3500 (actual power 1000W)
Function: Can be used with light bulbs, not home appliances

The special model for lighting is a brushless permanent magnet alternator, with a voltage stabilizer in the machine, and the working frequency is high frequency. It is only suitable for pure resistance household appliances such as lighting, TV, rice cooker, heating birdcage, electric stove, etc., and cannot drive electric fans. , Computers, refrigerators, washing machines, induction cookers, air conditioners, motors, angle grinders, water pumps, electric hoists and other electrical induction household appliances!

    The household frequency 50Hz model is a brushless excitation alternator. There is no voltage stabilizer in the machine. The working frequency is 50Hz. It can be used with electric fans, computers, refrigerators, washing machines, induction cookers, air conditioners, motors, angle grinders, water pumps, electric hoists, etc. Motor induction household appliances! When the generator is used for induction household appliances such as electric fans, refrigerators, washing machines, air conditioners, electric motors, angle grinders, water pumps, electric hoists, etc., the power selected by the generator is generally 2.2-3 times the power of the electrical appliances, because the motor The starting current of induction-like appliances is very high, otherwise the generator may be burned out.


I assume they work on resistive loads only because the frequency is not controlled?
So how do they control the voltage?

The reason I ask is because I'm looking for a DC generator that can supply 30 to 36 volts at 1000 watts.
And I wonder if this unit could be converted to do such a thing ? (Rectifying the wild output after removing the voltage regulator ... if there is one)
Strange little product.
Any ideas?

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 / Re: Chang-chai and ST head, deal? Or no deal?
« on: November 14, 2022, 03:15:12 AM »

My guess, and based on the size of the generator head ...
Model S195
HP 12
RPM 2200

The speed may be ok for that engine.
Many of the twins run at 1000 rpm.
