Interesting.

I'm sure I'd seen a similar design somewhere before. Didn't catch on because the industry hates changing things.

 

'Tis an interesting design.

What i can't see is what keeps the con rod in contact with the crank rotor when a piston is doing an induction stroke.

EDIT: yes i can.

very interesting design and it because its not too far from existing technology, ie uses conventional pistons rather than rotors etc. i could see this going into production in some form.

 

i agree.

might be a while before we see it in cars but I can invisage initial applications like lawn mowers / small generators etc etc

 

what about this one

massive yet tiny engine

or this one

mini V8

 

With two pistons opposing each other, it'd surely have to be much wider (or higher) than a conventional engine.

 

The shane engine:
Might find some limited applications but largely pointless. It's still based on a reciprocating cycle and I suspect has all the inefficiencies inherent to that. Too little scope for future development and doubtful to have the leap of improvement required to push the technology forward.

Having problems opening the second article to comment on

 

why's that first link keep ending my FF session?

Virus, ye buggers!?
