Okay, okay... I sorta overlooked some asterisks and left you hanging
with regard to the Sump Plate... so cut me a slack, okay? I gotta
take some pills & stuff.

(...but the Sump Plate is souper simple: You move the sump's DRAIN to
one of the 'down-hill' corners of the sump, which allows you to
install a PERMANENT sump plate... outta aluminum if you want minimum
weight or outta steel if you want to use it as a base for brackets or
whatever. Got some pitchers to show you... if I can findem')

Bob, you are writing history here as a US'an crediting a US patent to a
non-US'an! Indeed Mr. Charles Yale Knight, first holder of sleeve-valved
engine patents, was born in Indiana, USA, in 1868, at least that's what
I learn from http://en.wikipedia.org/wiki/Knight_Engine

Then again, his idea was based upon early concoctions by German Mr.
Otto, and then again his ideas were most succesfully implemented in
Europe, in some British aero-engines (Bristol Centaurus and its
predecessors) but also in the notorious luxury Minerva cars from Belgium
- that factory was close to my home, indeed the allies only nearly
missed killing my mother when trying to bomb the factory in May 1943.

As promised, three ILLUSTRATIONS of drawings depicting the later-model
VW dual port head. Posted to my blog: bobhooversblog.blogspot.com

Now I gotta go do my exercises. (My wife calls them 'Comic
Relief.' ( I got a TOUGH crew.)

if you were to take all the lessons learnt from all the engine
building done so far and apply them to a new engine design, what would
the new engine design look like?

A Subaru?

No. An air-cooled rotary.

Yeah an American invented it, but it took Harry Ricardo and crew to make
it really sing.

From what I remember from the vintage car meets is that the
sleeve-valve Willies-Knight, is that even in good running condition
would smoke like a two stroke. It's one of those screwy inventions best
left to the history books.

I think the flat 4 makes a very serviceable aircraft engine.
underslung pushrods like the O-200 and VW would remain.
I'd use hydraulic lifters.
the castings for the crankcase would be simpler, more like the O-200
than the complexities of the VW casing.
the crankshaft would be a little more robust at the front end
I'd fin the pushrod tubes and use the oil returning to the crankcase
as a radiator.
the engine would be mounted on dynafocal lord mounts.
I'd use electron for the crankcasings.
spin on oil filter. (z79)
magnet in the sumpplug.

what else???

Stealth Pilot

Would you please expand on "electron for crankcasings"

electron is a magnesium - aluminium alloy. lighter and stronger than
plain aluminium alloy for the casings. I'm pretty sure it is what vw
used in the casings.
however it doesnt lend itself to home greensand casting techniques
unless you can put an argon atmosphere above the molten metal.
the magnesium burns brightly at the surface of the molten metal.

stealth pilot

HEY!Thanks for the answer---Hadn't heard of that alloy--mosta my
castings used old cummins diesel pistons--heat treat really well!!
let one get too hot when treating --left a spidery matrix of copper..

IIRC, a lot of two stroke diesels, especially GM, used it successfully.
However, I don't know if they smoked any more than other diesels.

All of that is out there, already available. But the truth is, it's

What IS needed are aluminum head-castings having twice as much fin-
area as what's presently available. This won't fit on a bug or bus so
there is no start-up money. Coming up with the cores should have been
done by the EAA -- about fifty years ago. The fact it wasn't is good
evidence that it won't.

Bob...don't Jabiru use heads machined from billet stock?

That was my recollection as well, although I can no longer find it on the
web.
