Rotary internal combustion motor with spark plugs and pre-heating spark plugs

Rotary internal combustion motor comprising:

• a stator composed of a tight motor block, which comprises an annular shell closed by an opposite pair of identical lids, which house a compartment defined by two opposite planar surfaces, coinciding with the internal walls of the lids, and by an annular surface with elliptical profile, coinciding with the elliptical profile of the internal wall of said shell;
• a rotor, which is housed inside said compartment and comprises a cylindrical drum associated with a driving shaft supported by two main bearings housed inside bearing housings in the center of the two lids;
• an annular chamber disposed between the external surface of the cylindrical drum and the internal wall of said shell, wherein said annular chamber has a constant width, which is equal to the distance between the internal walls of said opposite pair of lids, whereas its height, measured according to a radial direction, is gradually variable, with increasing-decreasing-increasing progress, going from a minimum value to a maximum value that are repeated twice in a round angle of 360°;
• said annular chamber is formed of a pair of identical opposite semi-chambers;
• a regularly spaced set of primary radial blades intended to define portions of said semi-chambers, housed inside said cylindrical drum and radially sliding, the primary radial blades moving with respect to the external surface of the cylindrical drum, so that the top edge of said radial blades always adheres and slides against the internal wall of said shell during the rotation of the rotor, and the lateral edges of said primary radial blades always adhere and slide against the internal walls of said lids during the rotation of the rotor;
• at least one pair of inlet openings disposed in diametrally opposite positions, downstream the two points where said minimum height of the annular chamber is measured, along the direction of rotation of the rotor;
• at least one pair of outlet openings disposed in diametrally opposite positions, downstream the two points where said minimum height of the annular chamber is measured, along the direction of rotation of the rotor;
• at least one pair of injectors disposed in diametrally opposite positions, upstream the two points where said minimum height of the annular chamber is measured;
• at least one pair of spark plugs disposed in diametrally opposite positions is located within a spacing between adjacent primary radial blades at the two points where said minimum height of the annular chamber is measured;
• at least one pair of pre-heating spark plugs disposed in diametrally opposite positions is located within a spacing between adjacent primary radial blades at the two points where said minimum height of the annular chamber is measured.
