Abstract: An internal combustion engine comprising a rotor comprising a block (2), a drive shaft (5) and at least one piston set (1), all of them jointly rotating, wherein said piston set (1) is radially located with respect to the drive shaft (5); and a stator comprising a carcass (21), a first and second rotating support means (18, 19), and a first and second attachment means (17, 23); wherein the carcass (21) has guides (6) on its internal surface, which delimit the trajectory of each piston set; and wherein the inner end of the piston set (1) comprises a piston head (15) located inside the block (2), delimiting a combustion chamber, while at its outer end said piston set (1) contacts the guides (6).
