FIELD: machine building.
SUBSTANCE: invention can be used in rotary piston internal combustion engines. Internal combustion engine comprises housing (1) with rotary cylinder block (2) installed in it, in which cylinders (3) are made to accommodate pistons (4). In housing (1) there is internal cylindrical surface (6), which is tightly closed at the ends, elliptical protrusion with cutout (7), chamber (8) of a combustible mixture intake and chamber (9) of an exhaust gas outlet. Ignition plug (10) is installed in housing (1). Cylinder block (2) has outer cylindrical surface (11). In the head of each cylinder (3) there is hole (12) for passage of gases and hole (13) in the bottom of the cylinder for passage of rod (14) of the piston. Roller (15) is fixed on piston rod (14) with possibility of movement in cutout (7) of elliptical projection of housing (1) and slider (16) with possibility of its movement along parallel (17) made on block (2) of cylinders.
EFFECT: increasing engine reliability and simplifying its design.
