THE Deltic diesel engine, developed during the past few years in England by Napier is now in quantity production. The Deltic presents novel design features claimed to achieve a technical advance in current diesel-engine practice.
Some special features are discussed in the paper, and a description of the engine, its characteristics and performance is included. The general design philosophy behind the Deltic is outlined by the author, and some comments on reliability as applied to high-speed engines are set forth.
A survey is made of current applications of the Deltic, and a brief reference is made to future developments.
