Two-stroke is way forward

The Orbital system still squirts the oil in with the air though, so it
still gets mixed & burnt with the petrol. Anyway its sir.twatty's
design I want to hear about - I've got the blank patent forms ready to
go... ;-)

 

It was somewhere around Barstow, on the edge of the desert, when the
drugs began to take hold. I remember "Preston Kemp"

SirLadyboy's design would only run in dark car parks and need
considerably more than 2 strokes to do so.

Very slow link, and not quite on topic...

.... but this is *so* cool!

Stepped-piston, surely?

 

I reckon he's much more hair-trigger.

Monostroke.

 

There was a twin cylinder 2T with one cylinder the pumping cylinder and
the second the power cylinder. No oil in petrol. High 2T power out put.
Draw back was the increase in weight due to the pumping cylinder.

 

The thrashing noise in the background is one of these:

That's another variant. The area above the 'step' is used for
induction/scavenging, so it requires cylinders in pairs, each feeding
the other, IYSWIM. Below the large-diameter part of the pistons is a
conventional oil sump.

The opposed-piston design uses two pistons per cylinder as in the
Deltic animation that's posted elsewhere in this thread. One piston
uncovers the exhaust ports and the other uncovers the blower transfer
ports at the other end of the cylinder.

Ah, yes. Of course - I forgot about the Deltic. The Wulf was a
stepped-piston design, IIRC.

 

Just checked this. That is truly magnificent. )

 

Heh. Cheer up though mate, there are some preserved ones around

Shame that the original one doesn't still work though - that was the
coolest!
