This paper concentrates on the technical-scientific aspects of the development of the Doxford engine. The mechanical design of the engine is considered, as the technology in this area was well developed by the early 1970s and the engines in service experienced few mechanical problems. In thermodydnamic design, the technology was more patchy. Knowledge in the areas of turbocharging and combustion improved with the Seahorse engine, but geared engines are handicapped by their specific fuel consumption as compared with that of direct drive engines. The effort spent on the Seahorse engine was partly wasted, as the engine never entered service. The BS 42-100 project was terminated largely owing to the high predicted fuel consumption. The direct drive Doxford engines were competitive until single piston engines were developed for high-cylinder pressure and turbocharger efficiency. The success of the latest Doxford 3- and 4-cylinder engines, however, suggests that the opposed piston engine has great development potential. The paper finishes by describing recent improvements in the fuel system, the control system and the pistons. These improvements are supported by service results and substantiate the development potential of the engine.
