Problems associated with the use of synthetic atmosphere diesels in naval submarines

The concept of closed-cycle diesel engines and the advantages of using such a conventional power source to provide power reliably in a harsh environment have been discussed. The problems attending the use of such systems are highlighted and the attempted solutions appraised. Current research trends and themes are identified, and new ideas for solving the fundamental problems are presented. The roles that future closed-cycle diesel systems will have to fulfil are discussed in the light of projected work and operational requirements
