Rotating cylinder liner could improve efficiency

Article Abstract:

The Rotating Liner Engine concept could be extremely cost-effective if used on marine four-stroke diesels, according to Dimitrios Dardalis, a postgraduate student in the mechanical engineering department at the University of Texas. He believes that the technology could bring lower wear rates and allow longer operation at very high mean effective pressures.
