A rotary internal combustion engine comprising a housing containing a rotatable cylinder (28) having a circular wall (30) containig at least two rows of radially extending circular passageways (34, 36, 38) forming compression and power engine cylinders, respectively, displaced from each other along the axis of rotation. Each of the engine cylinders contains a freely reciprocal and rotatable spherical piston (42, 44, 46). A stationary cam is mounted within the housing surrounding each of the rows of engine cylinders, each cam consisting of a pair of edges (A, B) (C, D) (E, F) circular in diameter whose axis coincides with the axis of rotation of the rotatable cylinder. Each pair of edges is in contact with all of the spherical pistons within its respective row, the spacing of the edges varying over 360 degrees of rotation so that the spherical pistons move at a uniform velocity within each cylinder.
