Everything else / Re: Generator Enclosures
« on: April 10, 2021, 04:31:00 PM »

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.

Everything else / Generator Enclosures
« on: April 10, 2021, 04:29:40 PM »
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 ?

Bio-diesel Fuel / Re: Expain to me why you bother to make bio diesel
« on: April 07, 2021, 09:47:25 PM »
Yes, for diesel vehicles (expensive engines and a major job to rebuild), the best biofuel is Biodiesel.
For stationary engines (especially IDI) WVO or WVO blend is very convenient.

dax021,
Hey, no problem  ;)
A bigger concern for me was condensation.
Diesel combustion releases almost a quart of water as vapour for every quart of fuel burned.
With the muffler being located outdoors, there is a danger of water building up in the lower tank and then freezing whenever the engine turned off.
My solution was to drill a 1/2 hole at the bottom and weld on a threaded hub where I can screw in a ball valve.
During the winter I can crack open the valve and leave it open to drain any liquids.
We'll see if that works  ::)

I see in the youtube vid that you have a flexible hose connecting the engine and muffler. Where did you source the hose?
I would imagine a long length of that would absorb much pulse energy as well.
Cheers

Hugh,
It's called crush proof garage exhaust hose.
Very flexible and rated to high temperature (600f intermittent). Don't use it directly connected to the engine.
I suspect it could run at 300 f indefinitely.
Available in 2, 3, and 4". The one in the vid is a 2 inch.

Here is an example...

I got mine at Greenline Hose and Fittings.
There is a branch in Vancouver.

or, here is an Amazon example.

Will you bury the tanks or keep them above ground?
The tanks will stay above ground. I developed this muffler because I have no good location to bury one.

Why don't you turn that outlet pipe to face downwards?  That way it won't fill your tank with rainwater.

As noted above, the outlet is positioned to accept a screw-on stack.
The vertical stack will extend up above my garage and will have a rain cap on top.
The stack will be 3" PVC pipe.

Some have had adequate noise reduction using a 25 lb propane bottle.
The idea I wanted to try was to have 2 bottles in series creating a first stage expansion, and then a second stage expansion.
I purchased two 5 gallon portable air compressor tanks and with the help of a welder friend, added a few threaded ports so that the two tanks could be screwed together.
Also added were 2 threaded ports for inlet and outlet.
The outlet port is oriented to allow a vertical stack to be added.

Below are pictures during construction....

Here are two videos of the tests that I ran.
I must point out that in both cases there is also an automotive muffler at the engine (which are almost useless on their own).

First is a test with the listeroid. I did this test before finishing and painting the unit in case it was a failure.
It turns out that the muffler did a fine job of almost eliminating the noise. (Neighbours cannot hear it)

Second test was after the unit was completed and connected to a changfa engine running at 1150 rpm.
You will note that the engine is mechanically loud indoors, but outside the muffler is extremely effective.

Waste Motor Oil / Re: Good to see what you have done with WMO
« on: March 22, 2021, 07:01:23 PM »

"lowgear: I just changed out much of my fuel system on an Isuzu NPR.  I'm blaming WVO.  I'll not go back.  Smelled sweet while running but I'm over the "free" fuel."

Casey,
Did you try Blending ?
WVO and unleaded gasoline(RUG).
I have read that there are less issues because the WVO does not thiken up (polymerize) and gum up the fuel system.
80%WVO, 20% RUG

Consider a bit of Two Stroke fuel oil instead.
It's made for excellent lubrication when diluted 40:1
Would probably help the injector pump and valve guides

I took the Lister green to a paint store and had it matched to a universal paint number.
For anyone interested it is in the image below.

Listeroid Engines / Re: Simple Electric Starter for Listeroids

Looks like this Listeroid uses a standard AC motor as a starter and then the motor just "free wheels" after its turned off.
