A connecting rod and a crankshaft in traditional internal-combustion engines are omitted, and the protruding inner multi-phase cam swing transmission mechanism has no eccentric weight, and has the advantages that self-balancing of inertia force and work load. Rotation speed of the output shafts depends on transmission ratio of movable tooth transmission. If a movable tooth frame is fixed, high-speed output of the multi-phase shock wave wheel is achieved. The internal-combustion engine is widely applicable to fields, which need high rotation speed, such as helicopter engines and small power generators. When rotation speed is fixed, emission of harmful gas can be reduced. The internal-combustion engine is simple and compact in structure, low in axial size, self-balancing in stress, and stable in operation.
