The invention discloses an outer air pressing rotary piston engine which is made up of rotor, air pressing machine, press adjuster. The rotor has the same axes and hasn't pressing function, the air from air pressing machine and highly atomized fuel in rotor gas track are blended, then flows into firing room to burn and burst, force the rotor to rotate. There are 2-4 crescent grooves on cylinder of rotor, the shell correspondingly have grooves, it has counteractive board, the firing room is in front of the board. The shell also has oil ejecting port, high press air entrance, and spark piston.

The invention relates to a circuit topology structure of a large-power charging / discharging system and a control method of the structure, belongs to the technical field of power electronic technology,and aims at solving the problem that inverters in a present charging / discharging system circuit are connected in parallel directly and there is ring current among modules. Multiple converter circuitsare connected in parallel according to practical requirements, so that the output power of a current transformer is improved greatly. a zero-sequence component current is injected to the converter circuits, the ring current among the parallel-connected modules is inhibited effectively, the working efficiency of the parallel-connected current transformer is improved, and an intermediate potentialof a three-level structure is kept balanced. The structure can be used as a power electronic converter.

The invention has a compact structure, adopts an electronically controlled hydraulic mode to drive the valve for fully variable opening and closing, reduces technical power consumption, achieves the effects of energy recovery and action buffering, and has a high safety factor.

The present invention discloses a battery pack balanced control method based on a multi-coil transformer. According to the method, a public energy storage reservoir is set up in the charge-discharge process of series batteries; batteries with relatively high capacities input energy into the energy storage reservoir; and batteries with relatively low capacities adsorb energy from the energy storage reservoir. The input or adsorbed energy is measured by difference between the capacities or voltages of the batteries and a reference value; the larger the difference between the capacities or the voltages of the batteries and the reference value is, the more the input or absorbed energy is; and conversely, the smaller the difference between the capacities or the voltages of the batteries and the reference value is, the less the input or absorbed energy is. The energy storage reservoir is a multi-input multi-output multi-port energy reservoir, can simultaneously adsorb energy from a plurality of batteries with high capacities and also can simultaneously output energy to a plurality of batteries with low energy. Energy balance among battery monomers in a series battery pack is realized in an energy converting and deploying manner.

The invention provides a thermodynamic system and a method thereof. The thermodynamic system comprises a deflector, a magnetized body and two tubular magnets, wherein the two tubular magnets are coaxial and are nested internally and externally; each tubular magnet is formed by splicing a plurality of magnetic blocks; strong and weak spaced magnetic fields are formed between the two tubular magnets; the deflector is arranged between the two tubular magnets, and is coaxial with the two tubular magnets; the magnetized body is a thermosensitive magnetic material, and is filled in the deflector; the magnetized body is provided with gaps used for fluids with different temperatures to flow by at intervals; the magnetized body is contacted with the fluids with different temperatures, and thus, the current temperature of the magnetized body is changed, and further, the magnetized body is in a ferromagnetic state or a paramagnetic state converted at intervals; and after the thermosensitive magnetic material in the ferromagnetic state is under magnetic forces generated by the magnetic fields, the deflector is driven to continuously rotate. According to the thermodynamic system and the thermodynamic method provided by the invention, heat energy is converted into mechanical energy, and moreover, fuel combustion or emission of hazardous substances does not occur during a converting process, so that the whole converting process is environmentally friendly.
