I have just started using the Changfa 1115 engine with a 10kw ST Head to power our new house. Our power demands have risen some but not really very much. Anyway the old Listeroid GM-90, Satyajeet with a 12kw ST Head would run 4hrs on a gallon of fuel under 80-90% load. It ran at 765RPM, was set up for 750 but need a little extra to keep the voltage up under load.
The new Changfa uses more fuel, not sure just how much more but it is a noticeable amount. It is running at 1800RPM and powering a 10kw ST Head. Has anyone on this forum run one of these engines enough to get a fuel consumption rate on it?
Thanks ….Ken Gardner

If it was me it wouldn't be any kind of sandwich, but solid copper.

Copper gaskets are easy enough to make, if you have gasket problems and a head pull anyway, make a copper one and see how it goes, don't forget the annealing tho... did a thread some weeks ago about how to make one DIY...

I'm looking for the thread on making the gaskets, can't find it please point me the right direction

Ken, do you still have the old camshaft? Would you be interested in sending it to me for modification? I'll look at some of my other camshafts tomorrow to determine the possibility. I think I can turn the cam gear off of the hub and shrink a sprocket on it. It wouldn't hurt to have some rivets or bolts holding it also if there is room, although a good shrink fit shouldn't need it.  I have a 16/2 crank that is missing the crank gear. I can mike it but its no guarantee that it is the same size as the other listeroids.

I'll send one to you Monday morning if I can find you mailing address.

Oh NOOO!!    I lost another idler gear in my engine; this is the second one. The engine seemed to running just fine, no indication that there was trouble brewing, then bam, it was suddenly out of time, then dead.  The good part is there seems to be no damage to the cam gear. I actually didn't pull it out yet, just looking from the outside.
At any rate this is a 16/1 Saytajeet (GM90) and I would like to find out if there is a brass or bronze gear available for it. Other then a small inverter and old weak batteries this is our only source of power so it is imperative that we get her going ASAP.
In fact any ideas or opinions are helpful and welcome.
Thanks, You guys rock!!

Here are the pictures of the engine

I talk to some guys who run veggie in their vehicles and they are realy cautious about getting the oil too hot because this makes it lose its lubrication qualities.....cant be good for a diesel engine

Is the loss of  lubrication a problem with HOT Vegetable oil like it is withHOT Diesel? I didn't realize that VO lost it's lubricating properties with heat.

Re: Wood fired boiler ... Good idea, especially for the  cold climates.
However this would not get the combustion chamber up to operation temperatures so even if the VO was heated as well as the block the VO would not burn correctly for the first few minutes. Would this be a big problem? I really don't know but I don't think it is a good idea to burn VO in a cold condition. How long does it take for the combustion chamber to get to full operating temps? It seems like I need to run mine a few minutes before it is capable of full power out put on diesel. I believe that the best bet is to start on diesel then switch over after everything is up to operating temp.

One article said up to 150 Centegrade!. This is the key, I think.
Make the oil as hot as you can get it. Insulate the high pressure line to the nozzle. Start the engine on petro diesel and when hot and under loadswitch the source over to WVO. Run the engine as hot as you can.
This is the way I am going to run mine. As soon as I can.

Running these engines on WVO works just fine, however there seems to be a lot of mis-information about doing so. Be careful, 150*(c) is over 300*(f), I wonder what this would do to the Injector Pump. This seems to be way too hot, I believe that 180-200(f) is more in tune to what would work best.
There also was mention of changing the injector, I'm using the stock injector with no problem.
It is true, starting and shuting down on diesel or bio-d is a good idea. I don't know why one would have to switch when over "Under Load", I don't think it matters what the load is when the switch is made.
Be careful running the engine too hot, again all you need is 180-200*(f)
This has been my experance anyway.

This happened to us on a Sawmill drag chain once. I don't know how good you are at welding, we simply welded a bolt onto the remaining part of the Jib Pin. The portion that was welded was ground flat so as to get a good match on the surface of the pin. Then a Slide Hammer was attached to the bolt and the pin came right out with just a few whacks of the hammer. I think that the heat from the welding helped loosen it. Use caution here not to over heat the shaft!!
