Listeroid Engines / Re: slow running on start, then slowing down again
« on: September 05, 2023, 09:18:28 PM »
It doesn't sound like it's knocking or heavily loaded.
Could it be starving for fuel or air? Check the cleaner to make sure its not clogged with dust and debris.

A more complicated possibility would be a binding governor linkage.

When it slows down, can you physically see the fuel pump rack rod moving to a slower position?
If the rack is not closing, but the engine is slowing, then I suggest air or fuel starvation.
However, one would think that the rack would open further to try an speed up the engine.
( I'm scratching my head on this one )  ???

Well, if it uses a hopper cooling system which relies on evaporation and boiling of the water, I suggest temperatures of around 190f to 195f can be expected just below the hopper and around the cylinder head.

General Discussion / Does anyone have a Changfa R175 or R180 PDF manual?

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 ?

The pump is timed by the number of shims under it. More shims retards, less advances.

Am I correct in assuming that this timing is fixed through the entire operating range of the engine? Optimized for around 2000 rpm?

You are correct. There is no timing advance/retard for various RPM's.
Your engine is a "ZS" and is direct injected.
That engine sounds quite normal in the video.
Other things that can be construed as abnormal noises are the gear lash in these larger Chinese engines.
Due to having straight cut gears with lots of lash, the Cam, Counterbalance, and Start shafts, have a lot of gear clatter. And that too is normal.

Nice job !!! Keep on rolling  :)

General Discussion / Re: Running A/C compressor with Listeroid CS

Yes, it will probably work. You could also drive the condenser cooling fan from a pulley on the engine (or an alternator to a 12 volt fan).
Consider running straight heated vegetable oil for fuel. That would cut your fuel costs to near zero.

Changfa Engines / Re: Need help with flywheel timing marks

Hey Bronco,

Thanks for taking the time to do that. Not sure what to make of it.  "Please shut up"  LOL  ;D
The other issue is that there is no mark on the engine where these marks are supposed to line up with.

I will post what I find and we can see if any of the translations were close.

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.

<click on the pictures to enlarge>

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 ?


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.

Listeroid Engines / Re: 800 hours on 16/2...Toilet Paper Filter
« on: May 09, 2023, 03:53:22 AM »

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.
