The rotary engine operates in the four-phase work cycle and reaches the efficiency of the order of 48 % up to 64 % (according to the type), this resulting from engine geometry. The cylinder (1) has hole cylindrical in shape, this hole being tightly closed at both sides by two flat heads (2). The cross section of the cylinder (1) hole is the closed plane curve determined by the equation in the polar co-ordinates (r, f): r(f) = R1 + aR1sin f; for: f ELEMENT <0; 2 PI > where: R1 > 0, 0 < a </= 0,5. The shaft (3) crosses the cylinder (1) hole and is supported in the holes of both heads (2), and its axis is in line with the axis of said cylinder (1) hole. The section of the shaft (3) between the heads (2), i.e. inside said cylinder (1), is rectangular in cross section and cubicoid-shaped. The rotor (4) installed in said cylinder (1), made in form of an arm, divides the cylinder (1) from inside into two chambers each other sealed. The shape of the inside wall of said rotor (4), in its cross section, is defined by the closed plane broken line defined by the function in polar co-ordinates (r1, f): the engine achieves much higher efficiency than the piston engines owing to the course of the gas pressure force moment exerted against the shaft (3) during the work phase, this being a result of the engine geometry and the thermodynamic process. |
