An internal combustion heat engine, comprising: an upper cover; a stator with an exclusively cylindrical internal shape; a lower cover; a series of fasteners which join the stator between the covers (101, 104); a rotor capable of rotating, inside the stator and the covers (101, 104), with a prevalently cylindrical shape; a pass-through axis that is solidly connected to the rotor center, and is connected to the upper and lower covers (101, 104) by means of bearings and/or bushings that allow the rotor to rotate inside the stator and to the axis to transmit the motion of the rotor outside the engine; a mixture inlet hole carried by the upper cover close to the center thereof and to the axis, which receives at the input the comburent and combustible mixtures having a stoichiometric ratio suitable for the functioning of the engine, supplied at a higher pressure than ambient pressure; a series of holes and notches made both on the stator and on the rotor, suitable to operate in a complementary way to compress, remix, ignite, expand, discharge the mixtures and transform the combustion and /or the detonation of the mixtures in a rotational movement of the rotor; wherein said series of holes and notches comprises, made on the stator: pre-compression chambers, each followed by a combustion chamber, each followed by an expansion chamber, each followed by an exhaust hole; wherein said series of holes and notches further comprises, made on the rotor, a rotor chamber configured for facing, in sequence upon rotation of the rotor, said pre-compression chambers, combustion chambers, expansion chambers and exhaust holes; a ducts and channels series made on the rotor, constructed to compress, accelerate and centrifuge the mixtures inserted through the mixture inlet hole; said ducts and channels series comprising at least two bridge passages (403, 109), each consisting of: a channel carried by the rotor, a fixed bridge recess on the cover, a hole made on the rotor and communicating with the rotor chamber for feeding or supplying the mixtures into the rotor chamber only at an established point for mixture loading, through cyclic alignment of the channel and hole with the bridge recess when the rotor chamber faces the pre-compression chamber; series of holes (308, 309, 310, 311) able to house spark plugs, and these holes with a spark plug are gathered in the combustion chamber and are out of phase with each other, i.e. separate from each other by an angle in the same chamber, for determining advance and delay to ignition, suitable for triggering detonation of the mixtures in at least two combustion chambers symmetrically arranged on the stator. an upper cover;
