Napier Deltic Engine
The Napier Deltic engine is a British opposed-piston valveless, supercharged 
uniflow scavenged, two-stroke Diesel engine used in marine and locomotive 
applications, designed and produced by D. Napier & Son. Unusually, the cylinders 
were disposed in a three bank triangle, with a crankshaft at each corner of the 
The term Deltic is used to refer to both the Deltic E.130 opposed-piston high-
speed Diesel engine and the locomotives produced by English Electric using these 
engines, including its demonstrator locomotive named DELTIC and the production 
version for British Railways, which designated these as Class 55.
A single half-sized, turbocharged Deltic power unit also featured in the English 
Electric-built Type 2 locomotive, designated as the Class 23. Both locomotive and 
engine became better known as the "Baby Deltic".
The Deltic story began in 1943 when the British Admiralty set up a committee to 
develop a high-power, lightweight Diesel engine for Motor Torpedo Boats. Hitherto 
in the Royal Navy, such boats had been driven by petrol engines, but their highly 
flammable fuel made them vulnerable to fire, unlike the opposing diesel-powered 
While the Deltic engine was successful in marine and rail use and very powerful 
for its size and weight, it was a highly strung unit, requiring careful 
maintenance. This led to a policy of unit replacement rather than repair in situ. 
Deltic engines were easily removed after breakdown, generally being sent back to 
the manufacturer for repair, although after initial contracts expired both the 
Royal Navy and British Railways set up their own workshops for overhauls.
