This is different (ENGINE DESIGN)

[evoetr]

would i be correct in sayins its just a two cylinder 2 stroke but in a boxer configuration with a funny crank. Cant see many benifits over a inline twin two stroke, balance would be better, but takes up heaps of space, so probly not for bikes. Viffermans link has a super and turbo charged one, now this is an idea i like, pity it can only do deisel.
What i want to see in a bike is a supercharged direct injection petrol engine. KTM were working on a direct injection two stroke at some point but it must have stopped, pity.

I've seen some of the new BMW cross road bikes with a funny setup. Trying to find something out about them now, (I have seen some on the motorway and the engine sticks out side of the frame on both sides.... looked very ugly! But thats not to say it is because they have this type of design, it might be some other reason why the engine over hangs both sides.... )

hasn't BMW been using the opposing cylinder engine for decades???

[oldskool]

how would this be different to any other motorcycle engine layout in regards to clutch and gearbox?

sharp as ever Boom! maybe they're massive 1000cc pots.
What about Centre of Gravity issues.

True, I guess it might make the gearbox sit out allot further then normal motox engines making it a bit heavier on one side ? I don't know

It's not for motocross fool.

It's more like the bmw boxer engine.... but not a 4 stroke.....

Ahh i see way cool.... man they stick out a far bit though aye when you see them in a frame... keep thinking when im on the motorway and they go down the white line if a car was a bit to close and they hit it .... be like game over.... normally the only thing that over hangs is the mirror... hit that and just keep rolling through traffic

really ? self powered ?

NO it had a battery in it...

that army one is even cleverer. It's almost like 4 pistons in 2 cylinders thus doubling stroke for each bore therefore more cc's... more power. It's not really like a subie or beemer boxer as they're 4 stroke but as bogan said i can't see the advantage over a twin 2 stroke except for the opposing piston idea... that's cool

It is when you refer to the orignal question......... " Built in the 1920's by Robert Bourke its a twin cylinder 1stroke .. it fires every stroke the guys on on thumper were looking at it for possible dirt bike applications "

No fool here thanks... >>

ha ha haaaa, fuck a torch with a battery. you must be some kinda genius

lol only if it vibrates!

what about a wankel engine?

Solar Powered??? only works when there is sunlight...

I like the other designs sams come up with but we cant talk about those patent pending so youll have to wait. But watch out cuase itll fuck you up big time.
