I hear you guys.

From preliminary calculations for winter months -  i need to run the 10 kw for approximately 4 hours every day to heat a thermal water battery of 1000 liters from 20 degC to 60degC.

I have som powerhungry 400V tools, but have not yet made calculations to the exact need, point taken I,ll go back to the drawing board for power needs and fuel type.

Hi Chris

I think Cobba pin the point, and if you have a micro budget, dont jeopardize it. An HR (2, 3, 4 or 6) are direct injection and high RPM.

LEF members that uses WMO or WVO has low RPM engines Lister CS or listeroids, and thoes "fuels" need fine filtering, centrifuge to separate water, mixing to start and even heating to flow better.

Do you really need 10 KW? or 5 or 3 is sufficient?

Just a few cent to the rant!

Thanks for the reply. As I suggested there is a huge section on those 2 alternatives plus another 3 so that will keep you busy reading for a while.

Priority number one is of course to make the engine start and run well on diesel, but I am a very curious soul, so I'll have to check out the alt fuels at some point, WMO = waste motor oil, WVO=waste vegetable oil.

Hi Chris
Not sure what these are (WMO WVO) but assume they are alternative fuels. I have had no experience with these but there is a big thread on this Forum that covers this topic. I have no clue if they cause any excess wear and tear or not. I have been to Rallies where you can smell cooking oils being burnt in diesel engines and all it does for me is make me hungry.
Not sure of the cost of refining your own fuels and the time and trouble to make them or how much energy it takes to make it in the first place. All of these things you can find out in that area which is specially designed to help you out.

Yep, ordered fuel and oil filter - the airfilter is oil,so just needs a clean and fresh oil. I do intend to put it to work. As it is 22,6 HP @1500rpm I plan to run a 10-12KW generator, to take me partly or over time completeley off the electrical grid. As I am on a microscopic budget i would like to try out WMO and mayby WVO, but I have not researched if this engine is even suitable for that, which is a bit backwards :). Have you tried alternative fuels on your HR2?
The general idea was to have two gensets, a small one and a big one, so I'd have a back up and the small one promarily for summer and the big one primarily for winter and heating a large thermal batteri - anyway I am learning along the way and with the moneyb tank on low, it will take some time.

Coolant heat is routed externally via insulated PEX tubing to a remote mounted radiator
The majority of the heat generated in the enclosure will come from the surface of the engine and the windings of the generator head.

Has anyone enclosed a diesel generator for noise attenuation ?
I intend to surround my R175 Changfa with an close fitting insulated enclosure to really silence the system along with the new "dual tank" muffler.
My fear is that the generator head will overheat. It's a 4KW head which will be loaded to 1.5kw continuous.
If I run a cooling duct to the inlet of the generator fan it would create a massive channel for noise to escape.
How did you get around this issue?

Or ... maybe it's not an issue at all ?

I have removed injector/s and inverted them and connected them ack up o the fuel line and cranked the engine over to give me a very rough idea that the nozzle is actually atomising the fuel. But as suggested best way to check is on a pop off tester sothat they can be adjusted if required to the exact pressure required for your engine.
YEs carbon sparks is a good indication of carbon inside and possibly what got it on the move is the 2 stroke oil and not the engine oil.

lovely engine. hopefully you will change all the filters to be certain that all is in best condition. Engine oil, air and fuel filters. If doing the fuel filter then remember to bleed it all the wa along the fuel system. I bleed mine when needed into and out of the fuel filter housing then inlet and outlet of the pump then at the injector. It just makes it so easy. May even be worthwhile slipping the fuel tank off and cleaning it inside as well.
If you intend to put the engine back to work then I would run the engine and get it warm then drop the old oil out, maybe even a flush out with some kerosine and drain that too then add the new oil and filter.
