Title: Fairbanks-Morse Diamond engine
Post by: joncarrfarrelly on August 28, 2019, 02:33:55 pm
Another great article.
I'm sure many here are familiar withe Napier Deltic which was an outgrowth of Junkers
opposed piston designs, FM had the US Junkers license and this is what they did, it was
designed for subs.  :thumbsup:

Wow!  What a fantastic engine.  I love the fact that it has a void down the middle through which young engineering ensigns would be forced to crawl to adjust the intake thrust plunger flange lubricators (or just as a hazing exercise).

Did F-M use that design in their locomotive engines too Jon? I know they used opposed piston engines but not the actual configuration.

The loco diesels were also in the 38D8 family.
