Design and development edit
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[3] by Weslake, but which has to date failed to reach volume production.
Each crankshaft is linked by an idler gear to a centre shaft.[4]
