Compressed air is available, but oxygen is contained in the compressed air, which affects the service life of the cathode and anode, and oxygen-free gas, such as nitrogen, is preferred, which can prolong the service life of the cathode and anode.

The exhaust channel also passes through the water tank 4 to better cool the returned compressed gas medium; the water tank 4 is communicated with the water-cooling circulation channel 15 in the main shell 1 through a circulation water channel 41; be connected with control by temperature change fan 42 on the water tank 4 in order to lower the temperature to water tank 4, water tank 4 embeds has temperature sensor 43 and temperature sensor 43 outer antithetical couplet thermometer 44 in order to show the temperature in the water tank 4, temperature sensor 43 still is connected so that the electric rotational speed of control by temperature change fan 42 can be with the temperature phase-match in the water tank 4 with control by temperature change fan 42 electricity.

Thus, the high-temperature compressed gas medium which is cooled and reflows is further combined with the water tank 4 which is used traditionally, although the circulating water medium of the water tank 4 brings the temperature of the main shell 1, the high-temperature compressed gas medium which does work can also play a role in cooling the high-temperature compressed gas medium by heat exchange; when the device is implemented, the exhaust channel can be S-shaped in the water tank 4 and finally penetrates out, other spaces in the water tank 4 are circulating water, or conversely, the circulating water channel 41 is S-shaped in the water tank 4, and the high-temperature compressed gas medium is discharged after being sent into the water tank 4; the exhaust passage and the aluminum sheet of the laminated structure of the conventional water tank 4 can be arranged in a staggered manner as long as the heat exchange effect can be achieved; the water-cooling circulation passage 15 in the main housing 1 may be formed by conventional means and will not be described in detail.

The end of the crankshaft 2, which penetrates out of the main shell 1, is also in transmission connection with a generator 7 so as to drive the generator 7 to generate electricity, and the generator 7 is connected with a storage battery 71 so as to supply power for electronic devices; the end of the crankshaft 2 that protrudes out of the main housing 1 is detected by a rotation speed sensor 27 and said rotation speed sensor 27 is connected to a tachometer 28 for displaying the rotation speed.

In this way, the electric power is maintained, the service life is conveniently prolonged, and the storage battery 71 can supply power to at least the arc generator 5, the temperature-controlled fan 42, the air flow controller 312, and the like in the engine structure.

Two groups of cylinders are arranged in the main shell 1 and are in an in-line form, the structure of the crankshaft 2 corresponds to that of the crankshaft, and the two groups of cylinders work alternately.

Therefore, the power of the engine can be improved, the two groups of cylinders can provide the power of the exhaust stroke mutually by alternately applying work, the requirement on the flywheel 23 is avoided to be overhigh, and the crank throw corresponding to the two groups of cylinders is arranged at 180 degrees in terms of structure. Of course, in order to further improve the power, the number of the cylinders can be increased in groups, as long as the circumferential angle of the crank throw is correspondingly matched with the design.

The diameter of the crank throw correspondingly connected with the first piston 21 on the crankshaft 2 is smaller than that of the crank throw correspondingly connected with the second piston 22, specifically, the distance from the connecting journal to the axis is referred to.

In this way, power consumption can be reduced without affecting power. Because excessive compressed gas medium can generate heat when flowing in the pipeline, and the energy consumed for cooling is increased, the stroke of the first piston 21 is smaller than that of the second piston 22, and the high-temperature gas medium in the second cylinder 12 can be effectively pushed out by the air inlet of the first cylinder 11 in the air inlet stroke.

In practice, the main housing 1 includes a cylinder body and a cylinder cover, the cylinder cover is preferably a part above the camshaft 16, which facilitates the manufacture of the cylinder body and the cylinder cover, the cylinder body may be an integral structure or an assembly molding, and the description of the existing means is omitted.

The utility model discloses the main design thinking of engine is in confined cylinder space, and the high temperature electric arc that produces through discharging makes compressed gas medium thermal expansion and promotes the piston acting, and the acting stroke of piston promotes bent axle 2 with output torque. The two groups of cylinders have the same working form, only because the crank throw is 180 degrees different, the two groups of cylinders alternately apply work, one group of cylinders alternately provide torque in the exhaust stroke when the other group of cylinders apply work.

Comparative efficiency example:

a fuel engine: assuming that the engine cylinder diameter is 80mm, the stroke is 90mm, and the piston area is 50mm²The discharge capacity is 450ml, the air inlet pressure is 0.1Mpa, and the compression ratio is 10: 1, compression pressure 1Mpa, combined mist in combustion chamberThe pressure of the gasified fuel oil after combustion and expansion is 5Mpa, minus the exhaust pressure 0.1Mpa, equal to 4.9 Mpa, 4.9 Mpa is equal to 490N force, 490 multiplied by 50mm²Equal to 2450N, divided by 9.8, which is equal to about 2500KG force.

This pressure storage formula engine: assuming that the engine cylinder diameter is 80mm, the stroke is 90mm, and the piston area is 50mm²The pressure of inlet air is 10Mpa, the arc temperature is 6000 Kelvin, the pressure after high temperature expansion is 40Mpa, the pressure minus the exhaust pressure is 10Mpa, equal to 30Mpa, 30Mpa is equal to 3000N, 3000 multiplied by 50mm²Equal to 150000N divided by 9.8 approximately equals 15306KG force.

The power of the fuel engine for compressing air to do work is almost equal to the power consumed by the electric arc of the pressure storage type engine, the efficiency of the pressure storage type engine is 6 times higher than that of the fuel engine, and the larger the compressed air pressure is, the larger the engine power can be.
