engineeringtv.com — An extremely lightweight opposed piston opposed cylinder (OPOC) engine has been developed under a Defense Advanced Research Projects Agency (DARPA)program. FEV and Advanced Propulsion Technologies (APT)were asked by the U.S. Army Tank Automotive Research Development and Engineering Center (TARDEC) to modify this engine for heavy-truck applications.

maybe because it has three crank shafts? imagine doing a bottom end on one of those!

Yes but will it blend?

Something very similar to this with close to the same efficiency was in use years ago in motorcycle engines. They abandoned it for aesthetic reasons.

Damn, why am I going to college if it's so easy to be an engineer. You're right, degrees are a waste of time.
