Claims (7)

1. A method with fractional heat supply to the working fluid per cycle and continued expansion of the working fluid in the internal combustion engine by compressing air in an amount exceeding that required to burn a portion of fuel in one cycle, dividing compressed air into two parts, supplying the first part of air to the container isolated from the combustion chamber, and combustion of the fuel-air mixture in the combustion chamber, expansion of the combustion products into the expansion cavity of the engine and mixing of the latter with the second part of the air supplied from the isolated capacity in the expansion cavity of the engine, characterized in that the combustion of the fuel mixture is carried out at a constant volume in the combustion chamber isolated from the expansion cavity of the engine, the second part of the air is supplied to the expansion cavity of the engine on the expansion stroke through the combustion chamber when the combustion products expand to pressure, equal to the pressure of compressed air in the second part, and the supply of the first part of the air is alternately carried out in one of two combustion chambers operating alternately through one engine off, and as an insulated container for the second part of the air, an insulated air supply channel is used between the engine compression cavity and the combustion chamber. 2. A rotary-rocker internal combustion engine with continued expansion of the working fluid, comprising a stator on the inner surface of which two grooves are made, a rotor eccentrically mounted in the stator, a crankshaft axis with blades mounted inside the rotor, two combustion chambers made with the possibility of isolation using gas distribution bodies, the blades being connected to the rotor through a rocker hinge located in the rotor body, the first blade is placed in the first stator groove with the possibility of together with the surfaces of the stator and rotor of the injection section, divided by the blade into varying volumes of the suction and compression cavities, the second blade is placed in the second groove with the possibility of forming with the surfaces of the stator and rotor of the expansion section, divided by the blade into changing volumes of the expansion and exhaust cavity, its combustion chamber the inlet through the locking organs and the air supply channel are communicated with the compression cavity of the discharge section and the outlet through the locking organs - expand with the expansion cavity of the flax section, characterized in that the air supply channels are equipped with additional locking elements, installed with the possibility of isolating the channel from the compression cavity of the discharge section, the combustion chambers are straight-swirl, the movable gas joints of the rotor, stator and blades are equipped with a labyrinth seal, and the rotor enters the stator by c, determined by the following relationship:

where R _p is the radius of the rotor;
e-value of the rotor eccentricity;
R _p is the radius of the groove.  3. The engine according to claim 2, characterized in that the air supply channel and the combustion chamber are made insulated.  4. The engine according to PP.2 and 3, characterized in that the surface of the blades, rotor and grooves of the stator are made insulated.  5. The engine according to claims 2 to 4, characterized in that the volumes of the compression cavity of the discharge section at the end of the compression stroke and the expansion cavity of the expansion section at the beginning of the expansion stroke are zero.  6. The engine according to claims 2 to 5, characterized in that it is equipped with an additional expansion section.  7. The engine according to PP.2 to 6, characterized in that in the longitudinal direction is composed of several sections.
