The K6 ‘York’ rotary engine was conceived in January 2016, as a direct result of Jordans Consultancy needing to work within Network Rail’s axle weight limits for steam operations above 100mph (restrictions which did not exist during the ‘days of steam’).

It quickly became apparent that not only should the K6 rotary work for steam, but that it should also work for internal combustion using a wide variety of fuels.  Capitalising on Railfast Intermodal’s existing relationship with University of Birmingham, contact was made with Professor Miroslaw Wyszynski (MEng PhD Warsaw; MSAE, MSIMP) who in May 2016 began to oversee a number of over student projects over 2 years, aimed at investigating the performance and viability of the design (primarily in relation to internal combustion). 

Some results of the work by University of Birmingham are due to be presented by Professor Wyszynski at the 44th International Scientific Congress on Powertrain and Transport Means EUROPEAN KONES, Czestochowa & Wisla (Poland), 24th – 27th September 2018.

Once published by KONES, copy of the paper will be made available via this website.  Until a prototype has been built and its performance verified we do not wish as yet to go public regarding anticipated performance statistics, as compared to more conventional piston arrangements.  We are, however, willing to enter confidential discussions with interested parties.

A patent application was filed in April 2016 in relation to core aspects of the design, which was inspired by the ‘Gnome’ aero engine of World War I.

Potential applications for the K6 rotary are numerous and varied; essentially anywhere where a conventional piston engine is currently used.
