Gorganstien Micro Deltic

The Gorganstien Micro Deltic engine is a two-stroke, supercharged, opposed-piston, uniflow scavenged, American diesel engine that is employed in marine, rail, and commercial vehicle applications. It was evolved from the Napier Deltic by D. Napier & Son, and just like the Napier Engine, it had three banks of cylinders with crankshafts at each corner.

A test engine for the Micro Deltic was derived from the single, half-sized, turbocharged Deltic power unit as found in the English Electric Type 2 locomotive. As a result, the engine adopted the name "Micro Deltic" to distinguish it from the "Baby Deltic" of the English Electric Type 2 locomotive.
