MODULAR ROTARY INTERNAL COMBUSTION ENGINE Russian patent published in 2025 - IPC F01C1/344 F02B53/08 

FIELD: engines.

SUBSTANCE: invention can be used in internal combustion engines. Engine is composed of modules with selected parameters for a certain module. Certain module implements the corresponding stroke of the specified thermodynamic cycle of the engine operation. Modules are connected in series by elements of inlet-outlet paths. Modules have either the same or different rotation frequency. Modules can be located either on one shaft (6), or modules can be located coaxially, or arbitrarily in space with any type of mechanical connection. Rotor machine of the module comprises fixed housing (4) with grooves (8), rotor (5) which is rigidly fitted on shaft (6) and retractable device (RD). Grooves (8) with rotor (5) rim form cavities (9), which have inlet and outlet holes (12) or openings. Rotor (5) is made in the form of a wheel with a rim having a ring-shaped projection corresponding to the profile of grooves (8) of housing (4). In the body of the rotor, in channels-guides (15) isolated from the inside free space, there are either straight (16) blades, or curved blades. Straight blades (16) pass along diagonal line of rotor (5). If there are two straight blades (16), then they are located perpendicular to each other and extend from two opposite sides of rotor (5) into functional cavity (9). Blades (16) have a hinge joint with elements of RD. RD is based on either toothed-crank or toothed-crank-connecting-rod gear mechanisms and provides for extension and retraction of blades matched with rotor turn angle. Engine implements ICE cycles and consists of one or several sections of a pair of different-functional modules. One steam module based on a rotary or piston machine is compressor (2) and performs inlet and compression of the working medium. Other module of the pair is converter (1) and performs an expansion stroke with a heat supply and is built on the basis of a rotor machine with extending blades. Converter (1) converts thermal energy into mechanical energy, as well as exhaust. Sections are also located either on one shaft (6), or coaxially or randomly in space. Converter housing (1) has opening (12) for inlet of working medium into combustion chamber either from receiver (3), or directly from compressor (2), which is closed by valve. Combustion chamber (18) is made in the form of a truncated sphere, is a spherical recess on the rotor rim and is spaced from guide channel (15) of the blade outlet. In housing (4) there are ignition elements (13) or fuel injection nozzle.

EFFECT: ensuring continued expansion of gases and increasing specific power.
