We had a pair of 12cyl Fairbanks Morse 2 piston/cyl vertically opposed Diesels running on JP5 jet fuel in our 378ft Coat Guard as our main propulsion in addition to the Pratt Whitney 707 vintage jet engines for our 30+knot cruising. Way cool stuff for your basic motorhead. Below is very similar to the F/M engines - here's a link to an animation of a Napier Deltic marine engine, accompanied by the sound of a Deltic-powered locomotive: http://rowla.dyndns.org/justin/img/piston_deltic320.mpg
Daryl of AA Transaxle 425-788-4070 "On the cutting edge of Old technology" 86 Syncro Westy w/Turbo Zetec in the trunk -----Original Message----- From: Vanagon Mailing List [mailto:vanagon@gerry.vanagon.com] On Behalf Of Richard A Jones Sent: Friday, March 11, 2011 10:07 AM To: vanagon@GERRY.VANAGON.COM Subject: new engine for our Vanagons, maybe only on Fridays If this has been posted, my search didn't uncover it. It is pretty interesting--ex-VW engineer, boxer engine. Our Vanagons should last long enough to get one of these. ------------------------forwarded message--------------------------- This is no wimp engine. It's a two cylinder with four pistons delivering 300+ Horse Power It's extremely small and very efficient and is presently in use in test applications The configuration below is equivalent to a extremely ballsy four cylinder engine When doubled, it's an extremely ballsy 600+ H.P. engine
It's called OPOC (Opposed Piston Opposed Cylinder), and it's a turbocharged two-stroke, two-cylinder, with four pistons, two in each cylinder, that will run on gasoline, diesel or ethanol. The two pistons, inside a single cylinder, pump toward and away from each other, thus allowing a cycle to be completed twice as quickly as a conventional engine while balancing its own loads. The heavy lifting for this unconventional concept was performed Prof. Peter Hofbauer. During his 20 years at VW, Hofbauer headed up, among other things, development of VW's first diesel engine and the VR6. The OPOC has been in development for several years, and the company claims it's 30 percent lighter, one quarter the size and achieves 50 percent better fuel economy than a conventional turbo diesel engine. They're predicting 100 MPG in a conventional car. http://www.engineeringtv.com/video/Opposed-Piston-Opposed-Cylinder ----------------------------------------------------------------- |
