Ain't got the one I've always wanted to see. A one stroke engine.

Take an opposed piston design. Convert it to a swashplate and put a second piston head on the end of each piston. Now you have three bores, two pistons, four piston heads, and a power stroke on every stroke. The two pistons just get banged back and forth with a combustion at the end of each stroke. (A combustion chamber at left and right like a convention flat twin, and a "double" combustion chamber in the middle, serving the inner end of each piston - ie like a conventional opposed piston design (except that there isn't any such thing so it can't be conventional, but you know what I mean)

It's actually quite simple if you just think about it.

They did something similar with steam engines. I like steam.

EDIT: Charging has to be crankcase pressurised like a two stroke of course. So it's a one stroke two stroke

EDIT2. Actually I don't think it would need to be a swashplate. You could use two crank linked cranks, with the gudgeon pins serving as crankpins. Then link the cranks with conrods, like a locomotive engine (you'd need to extend the gudgeon pin crank pins into side bearer blocks, I guess to relieve the sideways loads on them which would otherwise be transmitted to the pistons).

It's really quite simple, and the only tricky part is the porting.

by far, the most impressive post in that thread, IMHO: has to be this one

The concept of how the engine works effectively is mind-numbing enough. I've never seen that concept before, let alone see it work. The intramaweb finally has another reason - research!!

One thing I've always wanted to do is build a 1:10th scale V8 from scratch. There's heaps of detailed manuals on the mighty Rover V8, Chev blocks, Ford V8s etc.. I thought a working scale engine would be quite an achievement.

Another amazing feat of scaling unbelievability (is that a word, Hitch?), is a fully working 1:10 scale Ferrari (can't remember what model) with a working flat 12, even clutch etc!! You need to dip the clutch to engage a gear!!! The whole car works exactly like the real mccoy, and even sounds like a Ferrari should!! I'll have a look for it and post it if I find it. It was featured on Jeremy Clarkson's Amazing Machines series from around the world..

Motu: picture 2 in the link with the opposed pistons.... is that from the British Deltic diesel loco in the 60's? I remember that as a World first and saw the loco itself when I was a kid.

B/J: I think I've still got that incredible Ferrari on a video somewhere. It was on the same programme as a scale Concorde which was amazing too.

Little story about here.
A bloke I knew that lived in Otara had a BSA A65 engine sitting in the corner of his lounge room.All polished up an looking real neat,but no internals.
A thief by the name of "Dino" broke in an stole it.
Then this dumb shit sold it to a Black Power member,telling him it was a runner.Said BP member wasn't very happy when he found out the thing was hollow.In the resulting beating Dino lost an eye.
Poetic justice

I tried to visualise that and suffered a stroke

Dino must of been a thicko alright,those things are bloody heavy! When I bought my A65 motor I went to see the bike as a burnt out wreck,the motor was fine,just covered in black soot and extingishure crap.It was downstairs in one of those flash Henderson brick and tiles made in the 60s,the guys mother was there, it all seemed cool - but when I went around in my car to pick it up,mother was nowhere to be seen,the place was full of Headhunters! I had to put it in the boot myself,but went home to New Lynn via Clevedon!

Where I was staying in Melbourne we has a Guzzi 250 4cyl sitting on the hearth - and my mate was building a Guzzi Convert he bought new in the crate,then set about gold plating it....half way through his project gold prices went through the roof and his job went out the window.The motor sat in the lounge with all covers and screw gold plated,just part of the furniture.

he he he,I was kinda waiting for somebody to say "I know a Dino with one eye"
He must still be out there somewhere aye!!

What a brilliant timewaster! However there were a couple of engines missing - the Honda RC174 (I know the 5 cylinder is there, but not the 6) and the 30 cylinder Chrysler A57 radial that powered the Sherman tank - essentially 5 side valve 6's on a common crankshaft.

The pic of the Honda is from the Two Wheels article about the replicas built by George Beale. And yes that is a credit card used for size reference

[Motu]

I see no sherman tank engine alright,but I've seen it posted on the ADV site before,some of the members are real engine guys....that was some motor,but sidevalves??? The Lycoming XR7755 is there though as an also ran.

I see a working drawing of a Gnome up now,showing the motor rotating and valves opening.As a side note to the Gnome and an earlier thread of mine - Ralph Watson has seen the rotary engine he hand built himself running,an effort from his friends to finish his last project.

Woz wrong wiv side valves. Like sidevalves. Nice and simple. Cuts out lotsa stuff what goes up and down and up and down and up and down an....., yeah, well, they're simpler, ain't they.
