Two-process rotary internal combustion engine, achieved by two thermal processes occurring alternatively in the rotary mechanical configuration.
Rotary mechanical configuration enables the Krajnovic process to take place, in which fuel burning occurs, with part of the heat being accumulated in the walls of the system. By utilizing accumulated heat of the system, Carnot cycle is realized over the revolutions of system cooling, whereby an amount of useful work is gained. The process is governed by two thermal processes taking place alternatively and by addition of the heat to the working fluid in the same system in two manners.
By isolating system from the environment, part of the heat is utilized which is in present-day designs rejected by radiation. By adding auxiliary expansion volume, better utilization of heat of burnt gases is achieved.
