I acquired this engine about 3 weeks ago, has any one ever seen one of these before ? if so what was it used for ?
I have searched around the internet trying to find out about it but I have had very little luck. Any ideas ??

Looks like one of the generic class "Changfa". Generally hopper-cooler, but yours has a radiator. If no water pump (some do, some don't) then thermosiphon cooling.

These run a good deal faster than the Lister(oid)s. I'd love to see that dataplate in focus. Std Lister(oid)s run 600-850 and the high-output ones up to 1000 RPM. I think this class runs closer to 850 at the bottom end, and maybe up to 1800 (?). Possibly only up to 1100, I do not know much about the Changfa-class engines.

I don't see a water pump so I am assuming it doesn't have one.

Ah, that there's a 25-yr-old one. The online converter says 14.4 PS = 14.2 HP. The 2200 RPM is surprising to me.

The low engine number may make it "collectable". I think you should collect the whole set!

This class of engine was/is a general-purpose prime mover. I'm told a lot of them are in use for pumping water and generating electricity, just like the Lister-class engines that came before them. I didn't know this style out of China was being mfg'd back that far though.

Click Here to see an interesting project, some what dated, but still will give you an idea as to what to do with this engine, the links on the side bar still work.

Hope this helps...

James direct-coupled his engine to the genhead, so he had to run it at 1800. The engine was rated at 14 HP @ 2200, and somewhere he says,

my diesel is rated for 14.7Kw at 2200rpm. Since I'm direct drive, I run the generator at 1800rpm, or 82% rated output rpm. 82% of 14.7Kw happens to be 12.1Kw *at the Flywheel*!! Assuming no one lied, the ST generator head must convert 93% of that energy to produce 11.2Kw of usefull electricity.

That was a linear function he used, which isn't correct. Running an engine at 82% of it's highest HP rating does not get you 82% of the HP of that rating.

But an interesting read nonetheless. James seems to be a renaissance man, he can do a wide range of things.

used on those self propelled tractor/trailer things---and general rural use.
using a belt you conect to pumps and chaff cutters.

they look like a tiller and box trailer.called rottary hoe overhere.

What intrigues me is the twin-headlight thing.

headlights for the tractor.

Just what I always wanted - a 150kg, diesel powered, flashlight.

I ran across a clue today, in Portland CL today:

Hand rototiller Diesel !! - $950 (Molalla)

This is a Yanmar diesel rototiller, It has 6 forward gears and 2 reverse

Anyone can operate this tiller, you squeeze the right handle & it turns right.
Pull the left handle and it steers to the left, no pushing or pulling at all.

It runs on diesel fuel, so it has a lot of torque to rototill fast & deep

It is 30" wide

For those got-to-till-after-dark jobs.

Looks like there is an attachment point up front for other implements. More than just a tiller - maybe a little walk behind tractor of sorts.

i think the bracket on the front is for wieghts.



its not uncommon to see these running other equipment like thrasher or generators.

a trailer is added to the rear and they are used as tractors[you sit on the trailer].
in australian books:
The powered rotary hoe was invented by Arthur Clifford Howard who, in 1912, began experimenting with rotary tillage on his father's farm at Gilgandra, New South Wales, Australia. Initially using his father's steam tractor engine as a power source,----,Unlike the Rototiller, the self propelled Howard Rotavator is equipped with a gearbox and driven forward, or held back, by its wheels.

the handle bars on our 1950's howard rotated around 360 deg.the idea it that you can walk on harder ground off to one side or drive in reverse.the engine was mounted low at the front sidways with several power take offs.

found this interesting.on a USA web site.

History:
The Romaine-Crosskill Digger was one of the first rotary tillers. It was built in 1857. Rotary tillage as we know it today was invented by Dr. Konrad von Meyenberg of Basel, Switzerland in 1910.-- The first Simar tillers of Switzerland were imported in 1932 by The Rototiller Company. The Rototiller was patterned after the Simar. Howard Rotavator of England[australian] sold walk-behind tillers in the USA during the '50s and '60s.
