Thake a look at this odd engine.
It should be a Napier Deltic (Napier was also producing the 24-H cylinders Sabre equipping Typhoons and Tempest Mk.V).
Does anyone know if this bizarre Napier Deltic engine worked for real, and if it had any use?

Reminds me of some Junkers diesel designs with similar magnitudy of oddity (counter-moving pistons forming the bore itself).

Was it the Jumo 205..?

No, is the Deltic engine. The Jumo was an opposed 'I' configuration.

Thank you a lot Milo, you're an amazing source of information!

Thus, Deltic was a 2-stroke diesel engine used mostly on british trains (and some boats), somewhat more powerful than "conventional" diesels (1800-2500 HP).
It was used until 1982 or so. Thanx also for the sleeve valve system!
