The invention relates to propulsion engineering and particularly to methods of operation of rotary internal-combustion engines and their structures. The problem solved by the invention is improving fuel efficiency and ecological compatibility, as well as providing the ability to set advance ignition, increasing the rotation frequency of a working shaft and decreasing its vibration, and making the manufacture of such an engine more cost effective. This problem is solved due to that the compression chamber is moved outside the working chamber and in relation to this chamber from the moment when compression of combustible mixture ends through the discharge of combustion materials into the working chamber. The rotary engine working according to this scheme comprises rotors mounted in it to move the compression chamber outside the working chamber and in relation to this chamber, the working chamber having a screen separating the intake port from the exhaust port. Furthermore, the rotary internal-combustion engine may have several combustion chambers for one working chamber, as well as several working chambers for one combustion chamber. At the same time, the compression chambers may be made connectable with each other. The working chambers may be also formed connectable with each other. Due to this arrangement one achieves more efficient application of active forces (due to the pressure from combustion materials within the combustible mixture) to a working shaft through a rotor.
A method of operation of a rotary internal-combustion engine which includes feeding components of combustible mixture in a compression chamber and a working chamber, their compression and ejection to the compression chamber, ignition and combustion of combustible mixture yielding combustion materials further directed in the working chamber, rotation of a rotor connected to a working shaft by combustion materials which are afterwards discharged from the working chamber, characterised in that the compression chamber is moved outside the working chamber and in relation to this chamber from the moment when compression of combustible mixture ends through the discharge of combustion materials into the working chamber.
A rotary internal-combustion engine comprising a housing closed with lids and provided with an intake port and exhaust port, wherein rotors are mounted in the housing and are gasketed against the walls of the housing, its lids and between each other, thus forming with them operational and compression chambers, characterised in that the rotors are mounted to move the compression chamber outside the working chamber and in relation to this chamber, the working chamber having a screen separating the intake port from the exhaust port.
