The invention relates to a rotary piston engine of stable combustion space consisting of one or more cylinders in a row seated on a common support base (11). Each cylinder consists of a cylindrical casing (1) of circular cross-section and the internal circular rotor (3) of eliptical cross-section with multiple lobes. The volumes are determined by the spaces between the casing and the rotor of three intermediary vanes. The one vane (9) separates the air inlet volumes (21) - fume outlet (20). The other two vanes (6, 7), to the front and rear of the combustion volume space (12) (located in the casing) are used interchangeably to separate the volumes of compression (13) - expansion (19). The change of position of the vanes (6, 7) is carried out when the pressure at the compression-expansion volumes becomes equal. Then part of these fumes is confined within the compression volume. This causes the air to preheat by the mixture of air-fumes and a final high temperature at the end of the compression which allows the use of different fuel. Moreover, the expansion ratio increases for the rest of the fume so that the temperature and pressure of the outgoing fumes are higher as is the thermal efficiency. |
