There is a need for a practical autonomous power-supply system for underwater work offshore, and the Diesel engine, using conventional fuels, is a strong contender for this application provided that various problems can be solved. Research at Newcastle University on these problems has reached the stage where a laboratory engine <a Perkins 3-cylinder Diesel with a maximum torque of 160 Nm at 1400 rpm and a maximum power of 38 kW at 2500 rpm> has been run under open, pseudo-closed and closed cycle conditions and has provided information which should assist in advancing the project, in which the University has been joined by an industrial partner, to the production stage after some further effort. The closed-cycle system adopted employs the nitro-Diesel concept, in which atmospheric nitrogen, trapped at the instant of closing the system, is the principal working fluid and is continuously recirculated through a cooler/condenser, a chemical scrubber for carbon dioxide absorption and an oxygen replensihment chamber. The author, of Newcastle University, describes and discusses the system, and gives an account of the tests carried out at the University.
