The invention discloses a piston driving device for testing the strength of a piston of a piston direct-drive engine, which comprises a box body and a driving motor, the piston direct-drive engine is a double-crest four-cylinder piston direct-drive cam engine, and the driving motor drives four pistons of the engine to reciprocate at a fixed phase difference through an eccentric disc transmission mechanism; the eccentric disc driving mechanism comprises an input shaft, a driven shaft and four eccentric connecting rod transmission structures with the same structure; the eccentric connecting rod transmission structure comprises an eccentric disc, a connecting rod structure and a piston connector, the connecting rod structure sleeves the eccentric disc through a rolling bearing and is connected with one end of the piston connector through a spherical sliding bearing, and the other end of the piston connector is connected to an engine piston; the input shaft and the driven shaft are rotary supporting shafts of the eccentric discs in each eccentric connecting rod transmission structure, and meanwhile the phase difference of all the eccentric discs is limited. During testing, piston working conditions change along with the input rotating speed, and then the strength of the piston is verified. Therefore, the device has the advantages of simple structure, easiness in assembly and adjustment and the like.

Systems and methods are provided for a camless reciprocating engine control system that uses laser absorption spectroscopy (LAS) sensors and artificial intelligence / machine learning to optimize engine operation. The control system evaluates LAS data in real time or substantially real time to optimize the operation of the engine through dynamic management of camless engine components such as intake valves, exhaust valves, fuel injectors, spark plugs, and variable compression mechanisms.

The application discloses a piston motion coupling closed cam engine, which comprises a box body, N piston assemblies, 2N guide members, a cylindrical cam and a swing rod; the piston assembly comprises a piston body, a piston head and a connecting rod, a roller is installed at the lower end of the piston body, the roller is in rolling contact with the cam surface of the cylindrical cam; the swing rod shaft on the box body is provided with the swing rod, the swing rod can rotate around the swing rod shaft and simultaneously contact with the connecting rod pin shafts in the adjacent two piston assemblies, the reverse symmetrical motion of the adjacent two pistons is coupled to realize the shape closure; the connecting rod pin shaft and the roller pin shaft axis in the piston assembly form a preset included angle to ensure the correct contact between the swing rod and the connecting rod pin shaft; each piston assembly moves along the axis according to the profile of the cam surface and drives the cylindrical cam to rotate under the constraint of the two side guide member moving pairs. The application can improve the output power through the motion coupling of two pistons, eliminate the gap impact, suppress the vibration, improve the dynamic performance, and the structure is easy to process and assemble.
