The present invention relates to a modified four-stroke internal combustion engine, which is a four-stroke internal combustion engine that performs suction, compression, explosion, and exhaust stroke in an inner space of a cylinder by a piston inserted into the cylinder and reciprocating. The invention relates to a modified four-stroke engine (internal combustion engine) which causes a cylinder block for inserting a piston to be rotated by a moving piston and forms an output shaft on the rotating cylinder block.

Before describing the present invention, a conventional four-stroke engine (internal combustion engine) will be described. Conventional four-stroke internal combustion engines have a plurality of cylinders (4-8) installed transversely with respect to the crank shaft inside a fixed cylinder block, and inserted into each crank shaft by connecting rods for reciprocating pistons. The driving force is obtained by changing the reciprocating motion of the piston into the rotational motion of the crankshaft.

In addition, circular gears 20 and 20 'inserted into and fixed to the ends of each of the crank shafts 14 and 14' are different from circular gears 19 inserted and fixed to the cam shaft 18 in the middle. Is interlocked. The gear ratio (circumferential ratio) of the circular gear 19 and the circular gear 20 and 20 'is 2: 1 and the circular gear 20 when the circular gear 20, 20' is rotated two times. 1 week is the circumference.

Each cylinder 15 (15A) 15B, 15C, 15D has a respective spark plug 46, a respective intake valve 47 and an exhaust valve 48, respectively. The intake valve 47 and the exhaust valve 48 inserted into each cylinder are connected to one side of the link 29 connected to the end of the operating rod 49 which operates in contact with the cam 27 of the cam shaft 18. Therefore, the inlet and exhaust of the cylinder is opened and closed. The operating rod 49 is inserted into the upper and lower brackets 50 protruding from the side wall of the cylinder to perform the correct up and down movement by the cam 27. An inlet gas passage 23 and an exhaust gas passage 24 connected to each cylinder are formed inside the cylinder block 11. The exhaust gas passages 24 of each cylinder are connected to each other through a center of the driving shaft 5. It is discharged to the outside.

The present invention having such a structure works as follows.

The present invention, like the conventional internal combustion engine, is initially started by shido motor (not shown in the figure). When the driving shaft 5 is initially rotated by the starting motor, the cylinder block 11 inserted into the upper and lower cases 1 and 2 integrated with the driving shaft 5 rotates. The rotation of the cylinder block 11 rotates the crank shafts 14 and 14 'inserted into the crank shaft insertion holes 12 and 13 formed above and below the cylinder block 11, and the crank shaft 14 The rotation of 14 'causes the piston to move up and down inside the cylinder when the piston 16 reciprocates each piston 16 connected to each connecting rod 17 inserted into the crankshaft, whereby the spark plug 46 Will actuate the piston. The reciprocating motion of the piston is, as with a four-stroke internal combustion engine, when the piston reciprocates twice, intake, compression, explosion and exhaust four strokes, that is, one cycle is completed.

When the pistons inserted into the cylinders 15 (15A), 15B, 15C, 15D exert an explosive stroke, the force on the crankshaft is rotated when the crankshaft 14, 14 'is rotated through the respective connecting rod. The lower end is rotated in the insertion slots 12 and 13 in relation to the lower end of the cylinder block 11 being inserted into the insertion slots 12 and 13. Further, since the circular gears 20 and 20 'inserted into and fixed to the lower ends of the crank shafts 14 and 14' are engaged with the circular stand gear 19 inserted and fixed to the cam shaft 18, the crank shaft ( The circular gears 20 and 20 'inserted into the 14 and 14' are rotated around the circular gear 19.

When the circular gear is rotated two times because the gear ratio of the circular gear (19) and the circular gear (20, 20 ') which is engaged with the circular gear (19) and rotates around the circular gear (19) is 2: 1. The gear will rotate once. Two revolutions of the circular gear means two revolutions of the crankshaft, which means that one cycle of intake, compression, explosion and exhaust is completed in the cylinder.

The circular gear 19 inserted into the cam shaft 18 is fixed to the circular gear 19 with the lower end of the cam shaft 18 inserted into the insertion hole 21 of the inner center of the lower case 2. Like the camshaft 18, it also has a fixed position which does not rotate. Therefore, the upper and lower ends are placed in the crankshaft insertion slots 12 and 13 of the cylinder block 11, and the crankshafts 14 and 14 'integrally insert the circular gears 20 and 20'. When it is rotated by the connecting rod 17, it rotates around the circular gear 19, and the crank shaft 14, 14 'inserted therein is rotated around the circular gear 19, the crank shaft (14) (14 ') The cylinder block 11 itself having the upper and lower ends rotates around the circular gear 19, that is, around the cam shaft 18.

The driving force is obtained by protruding the driving shaft 5 to the cylinder block 11 rotating around the cam shaft 18 as described above, and the center hole 6 of the upper case 1 in which the driving shaft 5 protrudes. The silver bearing 42 was inserted to smooth its rotation.

The valve opening and closing lever 28 inserted into the upper and lower brackets 50 on the outer wall of each of the cylinders 15A, 15B, 15C, and 15D rotates as the cylinder block 11 rotates, and the end of the cylinder is rotated. Since it is always in contact with the cam 27 of the shaft 18 by a spring, when rotating along the circumference of the cam 27, it moves up and down, and the upper end of the valve opening and closing lever 28, the intake air by the link 29 Or it is connected to the end of the exhaust valve, the valve opening and closing lever 28 to operate up and down by the cam 27 to open and close the intake valve 25 or exhaust valve 26.

The intake and exhaust ports of the cylinder opened and closed by the cam 27 of the cam shaft 18 are connected to the intake gas passage 23 and the exhaust gas passage 24 formed inside the cylinder block 11, respectively. The passage 24 is gathered into one and leads to an outlet formed in the drive shaft 5.

On the other hand, the inlet gas passage 23 of the cylinder block connected to the inlet port of each cylinder is gathered as one and leads to the mixed gas inlet 8 through the plurality of inlet gas through holes 22 of the lower case 2.

Lubricating oil supply passage 31 formed in the inner core of the cam shaft 18 is connected to the lubricating oil through hole 34 to each cam 27 to lubricate the end of the valve opening and closing lever 28 which is rotated in contact with the cam, It is supplied between the circular gear 19 and the circular gear 20, 20 'to reduce the lubrication and friction. In addition, the cylinder block 11, which is also supplied to the upper and lower bearings 43 and 44 and rotates around the fixed cam shaft 18, can be smoothly rotated.

Lubricated oil of each part is discharged to the lubricating oil outlet 10 of the lower case (2). In order to cool the cylinder block 11, a plurality of heat dissipation fans 51 are provided outside the cylinder block 11, and the upper case 1 has a plurality of cooling air inlets 7 and the lower case has a plurality of air outlets. (9) was formed. When the plurality of heat dissipation fans 51 attached to the outside of the cylinder block 11 are formed to be inclined in a spiral manner, air is forced into the cooling air outlet 9 by receiving air from the cooling air inlet 7. Mechanical seals (32) and (33) are inserted into the inner contact portion of the rotating cylinder block (11) and the lower case (2) that is not rotated to allow the cylinder block (11) to rotate smoothly, and the surrounding suction gas passage (23). ), So that no intake gas is leaked.

In the present invention, in operation, a plurality of cylinders 15 (15A), 15B, 15C, and 15D may be randomly exploded in order to obtain driving force, and two or more symmetrical cylinders may be simultaneously exploded to obtain driving force. have. That is, the timing of each cylinder explosion stroke can explode each cylinder sequentially or explode two symmetrical cylinders simultaneously when arbitrarily selecting the cam position of the cam shaft, the refraction angle of the crankshaft, and the setting of the ignition timing.

Such a present invention requires one more crankshaft than a conventional engine, but does not require a flywheel, a balance weight, etc., which are heavy, and thus can be manufactured in a small size and light weight as a whole, and high power can be obtained.

Such a present invention is a very useful invention that can be applied to an automobile engine that is sufficiently applicable to an automobile but requires light weight and high power.
