the linear generator is arranged below the piston internal combustion engine and specifically comprises a stator 112, a coil 113 wound on the stator 112 and a mover 114 slidably arranged in the stator 112 in a penetrating manner, wherein the mover 114 is connected with the piston push rod 102 through a piston push rod connector 107;

and the control system 116 is electrically connected with the oil nozzle 110, the air inlet valve 103, the first controllable valve 104, the second controllable valve 105 and the third controllable valve 111, and is used for controlling the oil nozzle 110, the air inlet valve 103, the first controllable valve 104, the second controllable valve 105 and the third controllable valve 111 to work in coordination when the piston 101 reciprocates.

The working mode of the generator adopting the structure is as follows: when the gas is combusted in the combustion chamber 108, the gas pressure expands to push the piston 101 to move downwards, the piston push rod 102 drives the rotor 114 to move downwards in the coil 113, meanwhile, the first controllable valve 104, the second controllable valve 105, the third controllable valve 111 and the gas inlet valve 103 are closed, and the compressed air energy storage switch of the gas storage chamber 109 performs high-pressure energy storage; when the piston 101 descends to a position between the first controllable valve 104 and the second controllable valve 105, the first controllable valve 104 and the second controllable valve 105 are opened, and the compressed air in the air storage chamber 109 enters the bottom of the combustion chamber 108; then the piston 101 reaches the bottom of a descending stroke, the air inlet valve 103 is opened, the compressed air energy storage switch releases pressure, the piston 101 is pushed to ascend, the first controllable valve 104 and the second controllable valve 105 are closed along with the piston, the third controllable valve 111 is opened, waste gas in the combustion chamber 108 is discharged through the third controllable valve 111 in the ascending process of the piston 101, meanwhile, the piston 101 drives the mover 114 to ascend in the coil 113 through the piston push rod 102, and alternating current is generated in a reciprocating mode. The starting is realized by starting the power supply. While the stroke control of the piston 101 can be braked by the coil 113.

In the whole working process of the generator, the control system 116 can control the air pressure of the air storage chamber 109 in the working process through the air inlet valve 103, the first controllable air valve 104, the second controllable air valve 105 and the compressed air energy storage switch, and can realize self-pressurization when the piston 101 moves upwards, thereby being beneficial to improving the power acceleration performance and the power generation efficiency and having strong practicability.

In some embodiments, the fuel injected by the injector 110 is diesel fuel, so that its ignition is initiated by the pressure upstream of the piston 101.

In some embodiments, the fuel injected by the fuel injector 110 is gasoline, and therefore, an ignition device is disposed on the combustion chamber 108, and the ignition device is configured as an arc ignition device to achieve arc ignition. Since such ignition structures have been widely used in the fields of ships, automobiles, and the like, and belong to the published category of the prior art, the specific structure thereof is not described herein any more, and the structural arrangement in the related prior art is referred for reference in the production process.

In order to monitor the air pressure in the air reservoir 109 in real time, in some embodiments, the air reservoir 109 is provided with a first air pressure sensor 120, and the first air pressure sensor 120 is electrically connected to the control system 116. In this way, during the operation, the control system 116 can control the operation of the first controllable valve 104, the second controllable valve 105, the intake valve 103, and the compressed air energy storage switch more precisely according to the air pressure of the air storage chamber 109 detected by the first air pressure sensor 120, and at the same time, the stroke of the piston 101 can be controlled through such detection, so as to avoid the risk of cylinder explosion caused by the fact that the downward distance of the piston 101 exceeds the stroke.

Similarly, in some embodiments, the combustion chamber 108 is provided with a second pressure sensor and an oxygen sensor 119, and the second pressure sensor and the oxygen sensor 119 are both electrically connected to the control system 116. The control system 116 can measure the air pressure and the oxygen concentration in the combustion chamber 108 in real time by combining the second air pressure sensor with the oxygen sensor 119, and further judge whether the fuel in the combustion chamber 108 is sufficiently combusted, so that the air discharge amount required by the next combustion is calculated, the combustion is more thorough, and the fuel utilization rate is improved.

Also, to avoid thermal damage to the combustion chamber 108, in some embodiments, the combustion chamber 108 is provided with a temperature sensor that is electrically connected to the control system 116.

Since the coil 113 in the generator generates alternating current, which can be directly connected to the power grid, but considering that most of the time battery storage is used, in some embodiments, the coil 113 is electrically connected to an electrical storage device, which includes a rectifier 117 and a battery 118. The alternating current generated in the coil 113 is rectified by the rectifier 117 to be direct current, and then stored in the battery 118. The power storage device may also be electrically connected to the control system 116, and may be managed and controlled by the control system 116. In addition, the rectifier 117 may also be integrated into the control system 116.

In some embodiments, the control system 116 is provided with a position detecting device corresponding to the linear generator, and the position detecting device is used for detecting the position of the mover 114. Specifically, the position detecting device is provided with a hall sensor 115, and the position of the mover 114 is detected by the hall sensor 115. Because the mover 114 is linked with the piston 101, the control system 116 can detect the position of the mover 114 through the hall sensor 115 to measure the movement distance of the piston 101, so that the control system 116 can adjust the movement of the piston 101 by integrating the position state of the mover 114, the position state of the piston 101, the combustion condition of the combustion chamber 108 and the air pressure condition of the air storage chamber 109, thereby avoiding cylinder explosion.

In order to ensure the air tightness of the air reservoir 109, it is preferable that the piston rod 102 is hermetically disposed with the cylinder casing 100. Since the piston rod 102 needs to move, the sealing arrangement here is a sliding seal, such as a sliding bearing.

The large two-stroke internal combustion engine for ships with the existing design is mainly increased by a Roots blower, the probability of mechanical failure and energy consumption are increased, the air pressure controllability of the large two-stroke internal combustion engine is lower than that of a controllable piston 101 self-supercharging cylinder in the embodiment, the power acceleration performance is improved, the discharged combustion gas is also controllable, and the large two-stroke internal combustion engine is close to the exhaust process without four strokes as much as possible, so that the oxygen content is increased, the combustion efficiency and the power are improved, and the stored energy is mainly supplemented by lower air compression and a coil 113 due to the absence of a crankshaft, so that the comprehensive combustion efficiency can be improved to the maximum controllability.

During the working process, the piston 101 realizes the stroke limit through the control system 116, for example, when the piston 101 goes down, the second air pressure sensor acquires pressure working data, the first air pressure sensor 120 acquires a real-time energy storage level, the control system 116 analyzes the upper working power to distribute the upper pressure lower end energy storage so as to bear most of the inertia kinetic energy brought by the piston 101, and then the position of the piston 101 is accurately controlled through the motor.

Besides, in some embodiments, the top and the bottom of the stroke of the piston 101 are both provided with spring stoppers, and the stroke limit of the piston 101 is realized by the spring stoppers, so that cylinder jacking or cylinder explosion is avoided.

The discharged combustion gas is controllable, so that the two-stroke residual gas can more fully discharge high-temperature combustion gas compared with the existing two-stroke internal combustion engine for the ship, the fuel efficiency is improved, and the temperature of the engine is reduced.

The total weight of the existing giant wheel internal combustion engine is close to 1000 tons, while the generator of the embodiment removes heavy castings such as a crankshaft, cast iron and the like, the weight of a working cylinder and a linear generator is 150 tons to 300 tons, and the total weight of the generator with the additional 200 tons of batteries is within 500 tons, so that the weight is lighter. And because the internal combustion engine generator can split the original engine into four or two, and can be maintained and operated one by one, the stroke is not delayed, and the maintenance and the replacement are faster. Meanwhile, when the storage battery 118 stores energy, the power output duration can be increased by 1 time in a short time, the real-time state of the whole power is monitored by the control system 116, the power can be protected more reliably, the power can be kept running well, and the abrasion degree of other parts such as the abrasion degree of a cylinder, the air pressure and the fuel efficiency can be maintained accurately. Compared with the traditional two-stroke internal combustion engine structure, the reduced structure can be used as a range extender of the existing electric automobile, a generator with lower cost and higher efficiency is provided, in addition, the Stirling steam engine can improve the fuel efficiency by nearly one time compared with the existing four-stroke internal combustion engine automobile, the power volume is smaller than the existing power, the manufacturing cost is also more ideal, the recovery value of magnetic steel and copper in the generator reaches nearly 5, and the value of the copper and the magnetic steel accounts for 4 to 6 of the value of the generator, so that the resource recycling is facilitated.

The above examples are merely preferred embodiments of the present invention, and may be combined to form new embodiments based on the above examples, and the present invention may have other embodiments.
