neat engine design

This is not necessarily Ducati related but motorcycle and generally kind of cool:

It's basically two pistons shoved into one cyclinder that oppose each other.

And yes, I used the word 'neat'.
 
So, did you get your 1198R yet????????????
If so, how do you like it so far?
You pulled a dissapearing act on us. Hopefully you have been riding the shit outta that R!!!
We need pics too!!
 
That's a uniflow engine. The design's been around for a long time. It's been used in steam engines, and Junkers produced diesel aviation engines of this type in the 1930s. Many of our WWII diesel subs were powered with 4 Fairbanks-Morse 10 cylinder uniflow engines. These engines are 2-strokes and require a scavenge air blower (supercharger for gasoline engine).
 
Don't mean to "thread-jack"; Ill make it short'n'sweet

Yeah, I "disappeared" because too many Douches were, well being and I refused to get caught up in that; considering that one of them was temp-banned for acting as such. I'm not here to participate at someone elses expense. I'll post more pics in a new thread (to clear all that out) when I pick up my boots this weekend. I ordered a set of 50th Anniversary Sidis back in February and I heard they just came in. Should match Noice! Bike just hit lil over 600, so its been sittin a bit; I'll be able to get to the first service this weekend too



Did not know that. Im just a young buck, so I'm learning every day. Seen opposed/boxer engines before, but not particularly designed like that. Is it rev-friendly?
 
As posted Junkers started the opposed piston engine. In the states we have Fairbanks Morse who still support their OP railroad engines. Opposed piston designs were just too complex and costly to manufacture and operate long term.

Now if you want to see a delightful opposed piston engine, google the Napier Deltic.
 
I'm surprised there are still F-M powered locos out there. They were expensive to service because the top cranks would have to come out to change a piston or liner, and that involved taking the roof off. EMDs could be serviced by just pulling an individual head.
 
yea but both of them are a PITA...Napiers are just a POS specially when it comes to turbochargers and the EMDs...i have like 6 of them around for back up and start up in case of a black out and all this weird design of powerpacks in combination with the even more worst planetary driven turbocharger design...all old technology though and there are much more efficient and maintenance friendly engines around in these days...
 
Yes, this is certainly not a new concept, but I'm a sucker fir these kind of things!

There are so many kinds of engine configurations, check out the Bourke engine.
