Double-phase shock wave swing rod type high-speed internal combustion engine

The invention discloses a double-phase shock wave swing rod type high-speed internal combustion engine, and relates to the field of fuel gas power. The invention provides a novel internal combustion engine, wherein eight cylinders are annularly, symmetrically and uniformly distributed around a convex inner central wheel, so that the resultant force borne by the convex inner central wheel is zero; cylinder pistons directly act on the convex inner central wheel through push rods; and the power is transmitted to an output shaft connected with a double-phase shock wave wheel key from the convex inner central wheel through a movable tooth transmission of a double-phase shock wave swing rod. In the internal combustion engine, a connecting rod and a crankshaft in the traditional internal combustion engine are omitted; and a double-phase shock wave swing rod transmission mechanism in the convex wheel has no eccentric mass and has the advantage of automatic balance of inertia force and working load. The revolution speed of the output shaft depends on the transmission rate of the movable tooth transmission; if a movable tooth rack is fixed, the double-phase shock wave wheel outputs power at a high speed; the internal combustion engine can be widely applied to the fields in need of high revolution speed, such as small generators, helicopter engines and the like; and when the output revolution speed is regular, the emission of harmful gases can be reduced. The internal combustion engine has the advantages of simple and compact structure, small axial size, automatic stress balance and stability in operation.
