Cooling for cooling the heat of the coil between the bobbin 70 having a double structure and the coil 90 and the coil 90-1 wound on the upper part of the bobbin so as to have a space where water can circulate for discharge. The plate constituted the auxiliary bobbin 80. The inlet 11 and 12 and the outlet 20 and 21 were configured to circulate water by forming a double wall structure for releasing heat generated from the solenoid portion 210 to the outside. That is, the water was configured to circulate.

In addition, the oil pipe 240 is built between the cylinder walls to configure the oil pump 340 to supply oil from the upper cylinder to supply the oil.

As described above, the heat generated by the long time use is a factor that inhibits the generation of the coil and the magnetic force, so the most important cooling system is very important. The purpose is to prevent the overheating of the solenoid part due to the heat of the coil due to the heat of the engine and to prevent the film from melting due to the overheating of the coil and the deformation of the coil due to the deformation of the coil due to the overheating. To apply a water-cooled system.

The water-cooled system forms the wall of the cylinder in a double structure to allow water to circulate therein to cool the heat generated by the friction of the piston, and the heat generated is transmitted to the coil so that the temperature is not increased so as to increase the temperature. The water is circulated and constitutes an outlet 22 through which heat-exchanged water is discharged.

In order to supply lubricating oil to the upper part of the piston, the oil pipe 240 is inserted between the double wall structure of the cylinder to supply the oil pump 310 to the oil pump 340 and the oil supplied through the inside of the cylinder to the water. The oil was also allowed to cool.

The solenoid portion 210 is configured to cool between the coil 90 and the coil 90-1 to the place where the most heat is generated, and the above configuration has a dual structure in which water can circulate inside the bobbin. If formed as the upper blade 30 and the lower blade 40 is made of the lower wing 40 is configured to push up to the upper blade 30 of the bobbin by configuring a coil 90-1 wound on the auxiliary bobbin 80 It is composed. In addition, the coil 90-1 is wound on the upper surface of the auxiliary bobbin, and an inlet 12 for supplying water to cool the heat generated in the coil by the circulating water and an outlet 21 for discharging the heat-exchanged water are configured. .

As shown in FIG. 5, the solenoid part 210 configured as described above is mounted on the upper portion of the upper solenoid 100 and the lower solenoid 100-1 on the upper portion of the cylinder 110. When fitting to the cylinder, it is possible to fix the forced fitting, welding of the coupling part, coupling method of the fastening bolt, etc.

The present invention is mounted to the lower portion of the cylinder and the projection 30-1 formed on the upper wing of the upper solenoid 100 mounted on the outer surface of the cylinder by the fastening bolt 290 and the fastening nut 290-1. The protrusions 30-1 formed on the upper wings of the lower solenoid 100-1 were coupled to each other.

3 and 4, the piston 140 is preferably made of a non-ferrous metal material that is free of magnetic force. The piston 140 may be used for a long time by using a material having excellent durability.

The piston constitutes an oil ring 130 to reduce the friction of the cylinder, and a plurality of vent holes 140-1 are formed to prevent compression in the cylinder head, so that compression is generated due to the reciprocating motion of the piston. It was configured so that no resistance would occur.

Inside the piston 140, as shown in FIG. 4, the permanent magnet 120 is inserted, and the inner housing 270 shown in FIG. Fastened with bolts as shown. In addition, the crank rod is connected to the piston (mounting the permanent magnet) is coupled to the piston pin 150, the crank rod 160 is connected to the crank arm 170 is connected to rotate the crank shaft 180.

In addition, the piston 140 has a structure in which a permanent magnet is inserted, and a plurality of vent holes 140-1 are formed in the vertical direction so as not to be compressed when moving from the bottom dead center to the top dead center so that air can be easily taken out. It was.

The arrangement of the piston and the cylinder shown in Figures 6 and 7 arranged in a 'V' shape and a 'horizontal type' is configured to not be affected by the magnetic force.

As shown, in the embodiment of the present invention, the arrangement of the cylinders is arranged in one or more rows by two or more, and the arrangement of the piston 140 requires that the piston 2 is arranged at the bottom dead center when the piston 1 is located at the top dead center. Since the output is symmetrically in the center, the vibration is minimized, and the symmetrical two forces can be used to generate a large force with a small current, and the power is generated every 180 degrees. Can be.

In addition, the lower part of the piston constitutes an oil bath for smooth movement of the crankshaft and the piston, and the piston-en oil ring 130 to prevent the lubricating oil from flowing into the cylinder.

The solenoid engine of the present invention is a power supply for the operation of the solenoid part, by using a SSR (Solid State Relays) by the sensor detection to send a current to the solenoid part to push the permanent magnet by the generated magnetic force. It was configured to repeat this process continuously. In the illustrated method of supplying power to the solenoid part of the present invention, the timing of the power supply is when the piston passes between 20 degrees and 30 degrees in the upward and downward dead center travel directions, and the power is supplied at the point closest to the coil wound bobbin. The position was configured to set the timing by configuring an optical sensor on the crank arm.

That is, an optical sensor is installed to detect when the rotational position of the crank arm passes between 20 degrees and 30 degrees in the direction of travel of the upper and lower dead center of the piston at a predetermined position of the crank arm 170 and is connected to the controller. The engine control unit is connected to the battery and the battery is connected to the generator. The generator is connected to the pulley and belt of the crankshaft.

When the material of the cylinder and the cylinder head is made of non-magnetic material, it is configured to increase the strength of the magnet by using a permanent magnet inside the piston.

In the embodiment according to the present invention shown in Figure 8 will be described the operation relationship between the water-cooling system for cooling and the solenoid portion mounted to the cylinder.

A solenoid portion in which a plurality of vent holes are formed, a piston 140 in which the permanent magnet 120 is inserted, an auxiliary bobbin 80 in which the coil 90-1 is wound, and a bobbin 70 in which the coil 90 is wound are arranged. Reference numeral 210 is arranged as an upper solenoid portion 100 configured on the upper outer surface of the cylinder and a lower solenoid 100-1 fitted to the lower outer surface.

Here, when power is supplied to the upper solenoid 100 configured at the upper portion of the cylinder made of the solenoid part, magnetic force is generated in the solenoid, and at this time, a repulsive force is generated to solely push the piston, and the piston descends toward the bottom dead center. At this time, the permanent magnet 120 configured in the piston reaches the state as close as possible without contacting the solenoid core inside the solenoid inner diameter, and the depth in which the piston enters the inner diameter of the solenoid is the maximum magnetic force. Therefore, due to the strong repulsive force of the solenoid, the piston strongly rotates the crankshaft 180 connected to the crank rod with a strong force passing through the bottom dead center, and the crankshaft rotation angle optical sensor 250 attached to the crankshaft at the position set before the bottom dead center. The solenoid installed in the upper part of the cylinder is cut off by the operation of) .In this case, the force pushing from the solenoid to the piston disappears momentarily, and the crankshaft passes through the bottom dead center by inertia and passes between 20 and 30 degrees. The current is supplied to the mounted lower solenoid 100-1 to continuously rotate to the top dead center position. When a magnetic force is generated, a force for pushing the piston is generated, which causes the piston to rise.

When the piston rises, the piston moves back to the upper solenoid 100 at the top dead center position.
The power is supplied and the piston pushes back to the bottom dead center. At this time, the lower solenoid is cut off the power and the piston passes through the bottom dead center again by inertia to supply power to the lower solenoid at the time of ascending, so the crankshaft is unbalanced. The crankshaft will continue to rotate without generating.

By installing an optical sensor 250 for detecting the position of the crank arm to configure a power supply timer that can supply and cut off the power to the solenoid portion is configured to control by the controller 400. The depth at which the piston enters the inside of the solenoid's inner diameter is the depth at which the magnetic force acts at the maximum. If the power supply of the solenoid acting on cylinder 1 is continuously rotated by the crankshaft and the power is supplied every 180 degrees, when the two cylinders are installed, the crankshaft operates the solenoid every 90 degrees. In particular, there is a characteristic that can obtain a strong rotational force and force.

Power is supplied to the upper solenoid of the cylinder head to generate magnetic force to push out the piston to make the piston strong descend.

The push force is maximized to obtain the maximum torque for the crankshaft. The power supply of the solenoid part is supplied from a charged battery (not shown in the battery).

Since the power supply and the power-off point of the solenoid part can be adjusted by experiments, it is not limited to the above angle but can be adjusted according to the required position.

The water-cooled system shown in Figure 9 is a water-cooled structure that can generate a high output while reducing the damage of the coil due to frictional heat in the cylinder and heat generated from the coil, the auxiliary wall using the bobbin 70 and the double wall structure using the double wall structure.

Cooling water is forcibly supplied to the circulation pump 200 through the hose 240 by connecting the dodge pipe 190 to the inlet 12 of the cylinder, the inlet 10 of the bobbin, and the inlet 11 of the auxiliary bobbin. . In addition, the heat-exchanged hot water is connected to the outlet tube 22 of the cylinder, the outlet 20 of the bobbin and the outlet 21 of the auxiliary bobbin by connecting the dodge pipe 190 to the heated water is discharged through the hose 240 to radiator ( 220 is a heat exchange through which the water is cooled. The cooled water is again supplied to the inlet by the circulation pump.
