The Weslake A80 is a liquid cooled, two-stroke, opposed piston, 1332 cc Diesel aircraft engine, produced by Weslake.
Design and development
This opposed piston aero-engine appears superficially similar to a true flat-four "boxer" engine, but is actually significantly different. It has two ported cylinders with a crankshaft at each end and four pistons in total. This engine is similar to the prototype Diesel Air engine, which was built for Diesel Air by Weslake, but which has to date failed to reach volume production.
Each crankshaft is linked by an idler gear to a centre shaft.
Applications
