Abstract: A modified spiral internal combustion engine is disclosed having a cylindrical housing, an intake end and a combustion end. A central shaft to which at least 2 spirals are attached is interposed through the housing. Fuel mixture enters the housing through an intake port and travels along the spirals toward the combustion end. The rotation of each of the spirals forms a sealed combustion chamber in the combustion end of the housing as they pass over the indentation in the end plate, which has the ignition devise. Ignition of the fuel within the chamber exerts a force on the combustion chamber portion of the spiral causing the central shaft to rotate. The rotation of the central shaft causes the combustion chamber portions of each spiral to individually pass by an exhaust port in the housing after they have ignited, allowing the spent gases to escape.
