Gyroscopic rotary engine

#The present invention relates to the field of internal combustion engines, in particular, to an engine for a rotary piston.

#In power equipment like various transportation vehicles, industrial and mineral machinery, etc., an engine is one of the most commonly used in these equipments. In the traditional reciprocating engine, crankshaft linked to the piston via a connecting rod transforms the linear motion into the rotation of the shaft. Because the directions of linear motion are frequently changed in the reciprocating motion, great inertial loss of components of the reciprocating engine, such as pistons, connecting rod, and the like, would occur when changing the directions. In addition, during the movement of the piston in the cylinder, the lateral pressure generated by the friction between the piston and wall of the cylinder acts on the piston continuously, resulting in power loss of the piston.

#Chinese utility model patent CN2076164U discloses a wobble engine comprising a cylinder block, a cylinder liner, a cylinder head, a piston, a camshaft, an inlet and exhaust device, a spark plug, an output shaft and an actuating device, characterized in that the cylinder block has a cylindrical shape which is divided into a plurality of cylinders by the cylinder head; a spindle is positioned in the center of the cylinder block and is surrounded by the arched cylinder liner; the copying piston is positioned into the cylinder liner in which the piston pole is fixedly connected with the spindle. When the cylinders are in operation, the power attained by of the spindle in wobbling motion of the piston in the cylinders makes the output shaft always moved in the same direction through an oriented ratchet and pawl mechanism.

#FIG. 1 is a top view of an embodiment of the invention;

#FIG. 2 is a sectional view of the embodiment of FIG. 1;

#FIG. 3 is a bottom view of the embodiment of FIG. 1;

#Referring to FIGS. 1, 2 and 3, an embodiment of the invention is a two-stroke diesel engine, which mainly comprises a rotary disc 1 used as a cylinder block, a cylinder head 2 and a gyroscopic unit 3.

#In this embodiment, the rotary disc 1 is a hollow cylinder having better dynamic balance, on an axis of the rotary disc 1 four arched cylinders 11 are disposed in an equally spaced manner.

#The cylinder head 2 is a fixed component. In this embodiment, the medium of the engine is fuel oil. In order to make air flow smoothly, medium outlets consist of a primary medium outlet 21 and a secondary medium outlet 23, and both are spacially arranged. The medium inlets 22 are used to jet the fuel oil, the primary medium 21 and secondary medium outlet 23 are used to discharge the waste gas generated by combusting the fuel oil. A partition area 24 is defined between the primary medium outlet 21 and the secondary medium outlet 23. The primary medium outlet 21 and the medium inlet 22 are respectively positioned to correspond to the positions of two of the four arched cylinders 11, so as to reasonably form a cycle for inletting and exhausting and an appropriate opportunity for jetting the fuel oil into the engine during operation. The above structures relate to the prior art, so their technical parameters are not detailed herein and can be chosen according to the technical parameters of general engines in the prior art.
