The invention relates to an opposed piston engine core structure and an assembling method thereof, and belongs to the technical field of internal combustion engines. The structure is constructed through the following assembling steps that firstly, the fixed gear ring is fixed to the cylinder body in a non-detachable mode, and a gear reference is formed; secondly, a crankshaft assembly integrated with a planetary gear is installed on the cylinder body, the planetary gear and the fixed gear ring are synchronously and internally meshed, and a motion restraining mechanism is formed; and finally, the pistons are assembled to the first shaft neck and the second shaft neck of the crankshaft through connecting rods in a rigid connection mode without movable hinges. According to the formed core structure, the piston-connecting rod system is forced to do linear reciprocating motion only along the axis of the air cylinder by utilizing the internal meshing constraint, and the lateral force of a piston in a traditional engine is thoroughly eliminated. The invention further provides an engine comprising the core structure. According to the scheme, the structure is compact, friction and vibration can be remarkably reduced, and efficiency and reliability are improved.

The application provides a single-stroke opposed-piston engine with a hollow main shaft embedded supercharging duct, and belongs to the technical field of special internal combustion engines and aviation power devices. The single-stroke opposed-piston engine with the hollow main shaft embedded supercharging duct can solve the problem of low natural scavenging efficiency of the single-stroke opposed-piston engine under high altitude environment without increasing the external volume of the engine. The single-stroke opposed-piston engine with the hollow main shaft embedded supercharging duct comprises a body, an end cover and a hollow main shaft, the body is internally provided with a piston, and an air inlet cavity is formed between the body and the end cover; the hollow main shaft is provided with an air inlet hole in the axial direction, and the free end of the hollow main shaft is connected with the air inlet cavity.
