How did you make out with the storm than hit?
Did the ROID do it's job ?

If you want to burn off excess solar (or use some extra battery capacity) just screw one of these into a small hot water heater.
They have a built-in DC adjustable thermostat. No fancy wiring needed. Turns itself on/off.
Note that they are available in a 700 watt/48 volt size also.

I have a 600 watt, 12 volt version that I intend to install soon.

If you teach new students this type of manufacturing, you will get more of .... this type of manufacturing.

Good work!
I too had governor linkage issues which turned out to be the spring tension and also a linkage that was binding (Alignment).

You are now ready! Caution.... You may find yourself praying for power outages.   ;D

+1 Looks like the right price for that equipment

Generators / Re: New project maybe?

I notice the seller states that it is seized so budget for possibly a new piston, cylinder liner, and maybe even a crankshaft re-grind with new bearings (if water got into the crankcase).
Without further investigation, you may end up paying more than if you had bought an engine that was already rebuilt.

He's probably on a "walkabout" picking up 260,000 liters of used vegetable oil.  ;D

Other Fuels / Woodgas CHP System

This fellow did a really nice job on a CHP package. Makes lots of DC power plus usable heat... AND runs on wood.

Engines / Re: Closed Loop Cooling (With Plate Exchanger)
« on: November 13, 2018, 02:38:01 PM »

Thanks guys,

ajaff1, your points about overheating are valid. I will be sure to add a high temp shutdown on the engine.
The engine has a fuel rack solenoid to allow shutdown from various sensors (Eg: Hi temp & low oil pressure)

cheers

Engines / Closed Loop Cooling (With Plate Exchanger)
« on: November 09, 2018, 05:11:13 AM »
Hi All,

I have a question...

My 2 cylinder Kubota generator project is almost complete.
I am now working on the cooling system.
My preference is to use a 30 plate heat exchanger that I have kicking around and run a loop from the engine to the plate-exchanger and back.
Then connect whatever I want to the other side of the exchanger to cool the engine water ( Fan/Radiator, floor loop, wall radiator, etc..)
Is it best to have an open (to atmosphere) system on the engine loop? or is it ok to run a closed sealed loop on the engine side?
I prefer to have it sealed so that  I don't need a reservoir/buffer tank, and I assume some type of expansion tank would be required like those used in hydronic heating systems.
Any thoughts, ideas, suggestions on this ?

The engine has it's own water pump and thermostat just like a car engine.

Original Lister Cs Engines / Re: engine oil
« on: October 30, 2018, 01:47:01 PM »

On the Lister CS engines the cylinder head (heat source) is physically very far removed from the crankcase.
Also, the oil is not circulated up to the head for valve train lubrication as in modern engines where much heat is absorbed..
The bottom of the piston and the cylinder bore are the contact points for heat in a CS (via splash lubrication).
There were times when I ran my roid for an hour and then checked the oil only to find it lukewarm.
Hence, as Glort stated, the conditions for lubrication are much different than modern engines and the Lister CS crankcases do not see the heat extremes that modern engine see. General purpose diesel lube oil should be fine. Straight 30W is very popular for CS engine users.

Well.... according to your bowl size, by my calculations you are creating approx 22,291 G's of force at 22000 rpm.
That's impressive.
As you stated, retention time and flow rate are critical to a good cleaning.
It would be interesting to see what happens with 2 or 3 passes through the unit.

I wonder if that debris on your burner tip is Ash rather than carbon.? Petroleum oils do have an Ash component when burned.

Nice job !

cheers !

Interesting project Ed,

I may have missed it earlier, ... what diameter bowl are you spinning at 17,500 rpm ?
