Changfa Engines / How many Changfa's do you want ?
« on: October 19, 2021, 04:00:02 AM »
Hello sir, how many Changfa generators do you want ?....

62 ?

Oh, no problem

Usually if the engine overspeeds, then the voltage goes up as well. (Depending on the generator head you are using)
Perhaps check for a voltage sensing relay (Ebay ??)

EG: If the voltage on a 240VAC generator raises to =>250 VAC, then trip the relay which energizes a kill solenoid on the fuel rack.

Just a thought

How big does the flywheel need to be so I can just turn the fuel off and have free energy?? ;D ;D ;D ;D

.... approximately the size of the planet.
Then turn off the lister 6/1 and draw 15 kw.
That should give you give you free power for generations.
But, eventually (maybe 23.6435 billion years) the power will fade.

I agree Mike90045,

Flywheels can't make power. They only add inertia (momentum)
There will not be any additional HP from the engine. (Physically impossible)
No amount of flywheel can make a 6/1 put out more than 3 to 4 kws of generator power.
His flywheel inertia may provide 15kva of stored energy for about 12 seconds  ;)
It's a scam.

Use a 6/1 to slowly (through transmission ratios) speed up a massive Mass Flywheel Storage battery (perhaps 4 tons in weight), to 10,000 rpm.
Then disconnect the engine and use the Flywheel battery momentum to drive a generator for X hrs (depending on how much load is applied to the flywheel inertia battery.)
However, he is not doing this.

Commercial Inertia Batteries are gaining in popularity. They use excess electrical power produced during the night to spin up heavy flywheels to high rpm.
During the day when the grid demands power, the flywheels power generators for several hours to assist peak loads.

Veg,, the flywheel tool doesn't fit the nut,, too small.

WOW ! A mystery spanner  ;D

The spanner is to remove the flywheel nut.
What you guys call the "spark plug socket" is used for con rod nuts and other internal fasteners.

Please report back when you adjust the IP timing.
I am interested to know how it effects the ignition knock and noise levels.

That CERTIFICATE OF QUALITY is amazing !   only 27,000,000 engines per year get that esteemed label, you are lucky to get one. Mine did not have such a label.

I have a couple of those.
Built like a Tank.
All cast iron, no aluminum.
They are heavy also.


Indirect injection.
Very tough little critters.

Thanks everyone for the fast replies.  ;)


Everything else / Bad Solar Panel
« on: September 15, 2021, 03:55:17 AM »

So, I just installed 4 x 220 watt solar panels on a rack mount system.
Somebody at the factory plugged the male and female MC-4 cables together on one of the panels.
When I took the panels out of their cardboard box on my lawn, it was a bright sunny day. Before I noticed that the one panel
was shorted out, it was too late.
3 panels put out 35 volts, 1 panel puts out ZERO.

Is this panel ruined? or is it possible that it could be repaired by opening the j-box and replacing diodes ?
At this point I have not done anything due to time constraints.


... and why is the rod bent?
Did the missing piece fall down and briefly jam the valve rocker right where the pushrod contacts the rocker?
Check all around the floor where you first removed the valve cover.

If you have the manual that came with the engine, check to see if there is a lever that is supposed to fit onto that decompression stub shaft.
My Changfa's came with an exploded view parts list (in Chinese of course). Although mine is a different model so it does not apply to your monster 1115

Ok, so your lever is not contacting the valve rocker. That's the issue.
Was there a part on the inside of that actuator that fell off?  A part that fits over that flat spot on the actuator and reaches the rocker?

You win this week's award for the strangest mystery in the entire universe !   ???


When you pull the decompression lever (with everything assembled) do you feel the resistance of the valve spring? or does it just flap without any resistance?

Very nice job there. A very good furnace and cooking surface.
With winter approaching, you will be the one that the women of the tribe choose to breed with  ;D


Here's a theory ...

If I am looking a the correct valve, the marks indicate that the de-comp lever is only contacting the edge of the rocker pad.
Being that the valve cover is held in place by a single stud in the center, the cover can be rotated somewhat to the left or right once installed.
Is it possible that the valve cover is being installed slightly rotated enough to make the actuator completely miss the rocker?

Also try holding the valve cover slightly rotated CW when installing. Then try again holding it slightly CCW.

See where I marked on the picture below....

just a thought,

Yes, the Changfa water cooled diesels are amazingly tough and durable.
