However, the length of the body 1 is increased. Other structures and principles are the same as those of Figs. 1-4, and the description thereof will not be repeated here.

Fig. 6 is a detailed configuration diagram of the entire crankshaft 33 of the present internal combustion engine.

In Fig. 7, the cylinder 10 and the piston 11 are above the piston rotating arm 3, and the center line E of the cylinder 10 and the piston 11 is perpendicular to the F line segment (the F line segment is: the piston rotating arm 3 is between the upper and lower dead points) In the middle position, the piston rotates the center point A of the arm pin 4 to the line of the center of the left and right rotating shaft 2, and the vertical point is at point B (point B is: the midpoint between point A and point C), C The point is the midpoint of the D line segment, and D is the straight line between the centers of the two piston swivel arm pins 4 when the piston rotating arm 3 is at the upper and lower dead centers. Thus, in the upper and lower movements of the piston 11, the thrust formed on the piston rotating arm 3 is maximized by the piston link 8. Of course, it is also possible to adjust the center line E of the cylinder 10 by the optimum timing of the maximum thrust generated by the piston 11 by the high-pressure gas generated during the fuel explosion, and the position of the intersection on the F line to achieve the maximum utilization of the piston thrust. Efficiency and reduce fuel consumption.

In Fig. 8, II is a straight line of the crankshaft connecting rod journal 13, a straight line to the center of the crankshaft main shaft 12; III is a center of the cranking rotary arm pin 7, and a straight line to the center of the right and left rotating shaft 2; I is a crankshaft main shaft 12 The center of the circle is a straight line to the center of the crankshaft rotation arm pin 7. When the straight line II is parallel to the straight line III, the straight line I is perpendicular to the straight line II and the straight line III. Thus, when the internal combustion engine is started, the starter motor gear 44 on the motor 45 is started to drive the crankshaft flywheel 34 with the gear and the overall crankshaft 33 to rotate, the crankshaft connecting rod journal 13 drives the crankshaft link 6, and the crankshaft rotating arm 3 The thrust effect is the best, and the force utilization efficiency is the largest. Conversely, when the high pressure gas pushes the piston 11, the piston 11 pushes the piston connecting rod 8, pushes the piston rotating arm 3, pushes the cranking arm 5, pushes the cranking arm pin 7, and pushes the crankshaft. When the connecting rod 6 moves up and down, the crankshaft connecting rod 6 has the best thrust effect on the crankshaft connecting rod journal 13 and the maximum utilization efficiency of the force, so that the utilization of the power can be improved and the fuel consumption can be reduced.

In Fig. 9, the rotating arm (including the piston rotating arm 3 and the crank rotating arm 5) is fixed on the right and left rotating shaft 2: on the left and right rotating shaft 2, the portion of the fixed rotating arm is square O (square tip) It can be rounded or chamfered (or polygonal), and the hollow part of the rotating arm fixed to the left and right rotating shaft 2 is also square (the square tip can be rounded or chamfered) (may also be a polygon). The shape and size are the same (or slightly larger) than the square O on the left and right rotating shafts 2. The length of the square body is slightly shorter than the length of the square body portion on the left and right rotating shafts 2, and the rotating arm is divided into two pieces from the square portion, one for The rotating arm main body M and the other one are the rotating arm gland N, and a gap Q is left on the contact surface of M and N, so that the screw P presses N and M against O, so that the rotating arm and the left and right rotating shaft 2 Installation is better than It is more convenient, and the fixing is relatively firm, so that there is no active gap between the rotating arm and the left and right rotating shaft 2, and the waste of useful work is avoided when there is a gap, and the fuel can be saved. {The general rotating arm main body M is large, the rotating arm pressure The cover N portion is small, and the M and N portions can be snapped into the outer surface of the square body portion O on the left and right rotating shafts 2 (the opening is larger than O) from the opening on the surface where they contact each other, All contact with the outside of O, and press them with screws P on top of O}.

The working principle of the internal combustion engine is that after the starting motor 45 is energized, the motor gear 44 is started to drive the crankshaft flywheel 34 with the gear to rotate, and the crankshaft flywheel 34 with the gear drives the integral crankshaft 33 to perform circular motion. In the circular motion of the overall crankshaft 33, the crankshaft connecting rod journal 13 drives the crankshaft connecting rod 6 to move up and down continuously, and the crankshaft connecting rod 6 drives the cranking rotary arm pin 7, together with the cranking arm 5 and the left and right rotating shaft 2 Rotating the center line of the axis of the left and right rotating shafts 2, and rotating the left (upper) and right (lower) alternately. At the same time, the right and left rotating shaft 2 also drives the piston rotating arm 3 to rotate leftward and rightward (because the piston rotating arm 3 and the cranking arm 5 are fixed to the left and right rotating shafts 2, so as long as one of them When the components rotate, they will rotate together at the same time. The corresponding piston rotating arm 3 drives the piston rotating arm pin 4 to move up and down together with the piston connecting rod 8. The piston connecting rod 8 drives the piston pin 9 together with the piston 11 in the cylinder. Continuously performing up-and-down motion in 10, completing the reciprocating motion of the piston 11 from the top dead center to the bottom dead center, and then from the bottom dead center to the top dead center (because the crankshaft connecting rod journal 13 is along the entire crankshaft 33 around the crankshaft main shaft) The center line of the shaft of 12 is continuously circularly moved, and the crankshaft connecting rod 6 is moved up and down with the rotation of the crankshaft connecting rod journal 13. Therefore, the diameter of the crankshaft connecting rod journal 13 when it is rotated circumferentially is the crankshaft connection. The rod 6 is the stroke length of the highest point and the lowest point of the up and down movement, and is also the length of the stroke of the piston 11. Similarly, the crankshaft connecting rod journal 13 controls the stroke of the piston 11, and likewise, the time and speed of the piston 11 moving up and down. Trajectory The crankshaft connecting rod journal 13 has the same trajectory of time and speed as the circular motion. It is the same as the trajectory of the piston of the conventional crank piston internal combustion engine. Therefore, their working principle is the same. Similarly, now common. Many of the principles, functions, structures, components, etc. of the crankshaft piston type internal combustion engine can be used in the same internal combustion engine, and will not be described in detail here, so that the internal combustion engine is easy to manufacture, low in cost, and reliable in technology. At the same time, the crankshaft main shaft 12 drives the crankshaft timing sprocket 28 Rotating, the crankshaft timing sprocket 28 drives the timing chain 26 and the camshaft timing sprocket 27 and the camshaft 22 to rotate. The camshaft 22 drives the valve rocker arm 25 and the intake valve 15 and the exhaust valve 16 to move in the valve spring. Under the action of the reverse force of 19, the intake valve 15 and the exhaust valve 16 are completed, and the continuous opening and closing operations of the intake passage 17 and the exhaust passage 18 are completed, and the corresponding intake and exhaust in the cylinder 10 are completed. Gas operation (in the description, for the sake of simplicity, when the cylinder is inhaled, the oil is sucked into the cylinder from the carburetor. If the oil supply is the internal combustion engine of the injector injection, the overall crankshaft 33 and the camshaft 22 need to be It drives and controls the operation of the oil pump and the injector. Their principle is the same as that of the conventional crank piston internal combustion engine, which will not be described in detail here. At the same time, the crank signal sensor 43 and the camshaft signal sensor 32 also sense the information about the overall crankshaft 33 and the camshaft 22, and transmit the information to the microcomputer (ECU) 46, which is operated by the microcomputer (ECU) 46 to control the ignition. The heater 47 and the spark plug 24 sequentially ignite the mixed gas in the corresponding cylinder 10 one by one in order to cause the mixed gas to explode to generate high-pressure gas and push the piston to move. The ignition sequence is: the cylinders on both sides alternately ignite. Thus, the internal combustion engine is started, and like the conventional crankshaft piston type internal combustion engine, after the internal combustion engine is started, the starter motor 45 is stopped. At this time, under the alternate push of the high pressure gas and the piston 11 in the cylinders 10 on both sides, and the crankey flywheel 34, the pistons 11 on both sides move up and down in the cylinder 10, and the cylinders 10 on both sides are continuously stopped. The mixed gas is sucked in, continuously ignited by the spark plug 24, and the high-pressure gas is continuously generated, and the corresponding pistons 11 on both sides are alternately pushed downward in order, and the pistons 11 and the piston pins 9 on both sides are alternately arranged in sequence. Pushing the piston connecting rods 8 on both sides downward, the piston connecting rods 8 on both sides push the piston swivel arm pin 4 and the piston rotating arm 3 on both sides of the left and right rotating shaft 2 to alternately move downward, and push the left and right rotating shafts 2 Stopping the left and right (up and down) swinging rotation {When the left piston 11 moves to the top dead center, the microcomputer (ECU) 46 controls the igniter 47 and the spark plug 24 based on signals transmitted from the crank signal sensor 43 and the camshaft signal sensor 32. The left cylinder 10 is ignited, and the mixed gas in the left cylinder 10 is ignited and exploded by the spark plug 24, and the generated high pressure gas pushes the left piston 11, the left piston pin 9, and the left piston rod 8 The left piston swivel arm pin 4, the left piston swivel arm 3, and the left and right rotating shaft 2 move downward (right) together, and at the same time, the left and right rotating shaft 2 drives the right piston rotating arm 3 and the right piston rotating arm pin 4 Move up (left) and push the right piston rod 8, the right piston pin 9, and the right piston 11 together also to move up (left). When the left piston 11, pushing the left piston link 8, and the left piston rotating arm 3, moving down to the bottom dead center, under the control of the camshaft 22, the exhaust valve 16 is opened, at this time, the left side The piston 11 has no thrust on the left piston rotating arm 3. At the same time, the right piston rotating arm 3 pushes the right piston 11 up (left) to the top dead center, at which time the microcomputer (ECU) 46 controls the igniter based on the signals from the crank signal sensor 43 and the camshaft signal sensor 32. 47 and the spark plug 24 ignite the cylinder 10 on the right side, and the mixed gas in the cylinder 10 on the right side is ignited and exploded by the spark plug 24, and the generated high pressure gas is pushed. The right piston 11, the right piston pin 9, the right piston link 8, the right piston swivel pin 4, the right piston swivel arm 3, and the left and right rotating shafts 2 begin to move downward (right). At the same time, the left and right rotating shaft 2 drives the left piston rotating arm 3, the left piston rotating arm pin 4 moves upward (left), and pushes the left piston connecting rod 8, the left piston pin 9, and the left piston 11 together (left) )motion. When the repetition is repeated as described above, the right and left rotating shafts 2 are formed, and the left and right alternate rotations are continuously performed}. Conversely, the right and left oscillating rotation of the right and left rotating shaft 2 also drives the cranking arm 5 and the cranking arm pin 7 to perform left (upper) and right (lower) oscillating rotations, and the crankshaft rotates the arm pin 7 to drive the crank link 6 The lower movement and pushing the crankshaft connecting rod journal 13 drives the integral crankshaft 33 and the geared crankshaft flywheel 34 to rotate together, so that the overall crankshaft 33 and the geared crankshaft flywheel 34 continuously rotate, and at the same time, the crankshaft main shaft 12 drives the crankshaft positive Time sprocket 28, timing chain 26, camshaft timing sprocket 27, camshaft 22, valve rocker arm 25, intake valve 15, exhaust valve 16, crankshaft signal wheel 42, camshaft signal wheel 31 and others The gas distribution, oil supply, ignition and other mechanisms work to make the engine run automatically. The internal combustion engine automatically completes each stroke and continues to work on the next stroke to keep the internal combustion engine moving. The ordinary crankshaft piston type internal combustion engine works in the same principle and will not be described in detail here. (Because of the inertia of the geared flywheel 34, the mechanism such as the piston 11 is driven to complete the movement of the stroke other than the power stroke, especially for the internal combustion engine of four cylinders or less, the movement of the stroke other than the work is completely dependent on the inertia of the crankshaft flywheel. Driven so that the internal combustion engine will never stop working). At the same time, the left and right rotating shafts 2 also drive the one-way clutch gears 35, 36 to perform the left and right swinging rotation, and the locking is performed when the one-way clutch gear 36 is rotated to the left, and the one-way clutch gear 35 is locked when rotating to the right. Tightly (simultaneously changing the direction in which the two one-way clutch gears 35, 36 are engaged, the direction of rotation of the output shaft 39 can be changed, and the ratio of the number of teeth of the two one-way clutch gears 35, 36 to the power output shaft gear 41 can be changed. The output speed of the power output shaft 39 can be changed. Then, when the left and right rotating shaft 2 is rotated to the left, the one-way clutch gear 36 is in a locked state, which drives the power output shaft gear 41 and the power output shaft 39. And the power output shaft flywheel 40 rotates to the right together, and at the same time, the one-way clutch gear 35 is in an unlocked state, it is idling, does not drive the rotation of the wheel 38, and the wheel 38 follows the power output shaft gear 41 to idle to the left. When the left and right rotating shaft 2 is turned to the right, the one-way clutch gear 36 is in the unlocked state, it can only be idling, and then the one-way clutch gear 35 is in the locked state, which drives the wheel 38 toward left When the wheel 38 is rotated, the power output shaft gear 41 and the power output shaft 39 and the power output shaft flywheel 40 are also rotated to the right, and thus repeated. Thus, the four gears rotate the left and right rotations of the left and right rotating shafts 2 into a continuous circumferential rotation in one direction, forming a complete power output mechanism. Since the left and right rotating shafts 2 directly pass the left and right swinging rotational powers of the right and left rotating shafts 2 to the power output shaft gear 41 and the power output shaft 39 through the two one-way clutch gears 35, 36 and the overrunning gear 38, In the transmission of the force of the gear, the loss of force is small. So, this In the internal combustion engine, the power output efficiency of the fuel explosion work is very high, and the efficiency of the work is higher than that of the crankshaft output power, which can save a lot of fuel and reduce a large amount of exhaust gas emissions. Further, in the internal combustion engine, the cylinder block 52, the piston rotating arm chamber 53, the power output gear chamber 54, the crank rotating arm and the crank chamber 55 are all connected together to form an integral body 1, so that the overall stability of the body 1 is enhanced, so that Left and right rotating shaft 2, power output shaft 39, integral crankshaft 33, piston rotating arm 3, cranking arm 5, gears 35, 36 with one-way clutch, over-wheel 37, over-wheel 38, etc., are respectively fixed at these 3 The indoors make these parts stable and stable, and the internal combustion engine has the advantages of firm body, small size, short length, light weight, low cost, convenient installation and maintenance of parts, etc., which makes the operation of the internal combustion engine more stable and power transmission. The effect is better, reducing unnecessary fuel waste and forming a “structure-optimized energy-saving internal combustion engine”.

The shafts in the internal combustion engine are fixed on the body 1 and the cylinder head 21 by means of bearings, bushes, etc., and the gears and flywheels are fixed on the respective shafts by means of keys or splines and welding, and the pins are used. The circlip, the screw, the welding, the split pin, etc. are fixed in the hole, and other parts are also fixed on the body 1 by screws, welding, etc., for the simplicity of the description and the clarity of the drawing, in the drawings Not shown, there is no detailed description in the manual. The carburetor or fuel injection pump, fuel injector and other mechanisms are not shown in the drawings and instructions. The cooling water tank of the cylinder is not shown in the drawings. Do some explanation.

In the present internal combustion engine, when the number of cylinders 10 exceeds 4-6, in the middle of the piston rotating arm chamber (53) of the body 1, a wall is added, and at the same time, the left and right rotating shafts 2 are correspondingly increased by one. Bearing, this one bearing is fixed on this increased wall to increase the strength of the left and right rotating shaft 2; if the length of the power output shaft 39 is increased too much, one or more bearings are added in the middle, the one or more bearings It is fixed to the corresponding wall to increase the strength of the power output shaft 39.

In order to reduce the weight, in the body casing of the internal combustion engine, the place where the force is not applied is as thin as possible, and the rib is used in the place where the rib is used. In short, the material, structure, strength and mechanical structure are calculated to find out Reasonable structural shape of the casing. In order to save space and volume, and also for the appearance and smoothness of the appearance, the corners of the external surface of the machine are designed as circular arcs as much as possible. The overall structure of the machine body is designed to be smaller and lighter in weight than the mechanical structure.

Because the piston stroke of the internal combustion engine is controlled by the crankshaft, the stroke of the piston is exactly the same as that of the piston of the conventional crank piston internal combustion engine. Therefore, all modern types of crankshaft piston internal combustion engines are started, Various systems for oil supply, gas distribution, intake, exhaust, ignition, lubrication, cooling, etc., various functions, mechanisms, and components can be used in this internal combustion engine, but some of them can be used directly. Such as: cylinder, piston, cylinder head and many parts on cylinder head, gas distribution mechanism, oil supply mechanism, ignition mechanism, starting mechanism, cooling mechanism, carburetor, fuel injection pump, oil pump, generator, pump, air conditioner Compressors, etc., some in this energy saving When it is used in an internal combustion engine, it must be placed in an appropriate position in the internal combustion engine when it is connected and fixed to the corresponding mechanism and parts in the internal combustion engine. Some of them must be in a suitable shape to become a suitable connection method. To adapt to each other, to cooperate with each other, and to fix them, the functional principle is unchanged, such as: intake pipe, exhaust pipe, lubricating oil circuit, oil supply system, cooling system, distributor, etc.; thus, it can save costs and reduce investment. , reliable performance and easy to manufacture.

Since the output portion of the internal combustion engine has no crankshaft, it has no dead point of power output, and the piston stroke is the same as that of the ordinary crank piston internal combustion engine. At the end of the stroke, the rotational thrust of the power output shaft is still large. Because the piston of the crankshaft piston type internal combustion engine has a small force against the rotation of the crankshaft and the connecting rod at the end of the stroke, it is a dead point), and can also be utilized, so that the piston stroke of the internal combustion engine can be lengthened (at the same time, It is necessary to increase the distance between the crankshaft main shaft and the crankshaft connecting rod journal or reduce the length of the crankshaft rotating arm to increase the utilization efficiency of the high-pressure gas generated during the fuel explosion, reduce the fuel consumption, and at the same time, put in and out The valve and the intake and exhaust passages are enlarged to increase the amount of intake and exhaust, to ensure the supply of oxygen, and to discharge the exhaust gas smoothly.

The bearings on the shafts of the internal combustion engine can be selected according to the size of the shaft itself. Suitable deep groove ball bearings or roller bearings can be used. In one bearing position, a single bearing can be used, or two bearings can be used to enhance. The bearing's bearing capacity and life, if necessary, can also add a plane thrust bearing on the required shaft to increase the axial thrust.

The shaft of the internal combustion engine generally has a larger diameter at one end and a smaller diameter at the other end. The size of the bearing at both ends and the middle portion of the shaft is adapted to the diameter of the corresponding portion on the shaft, and the bearing of the fixed bearing on the body is fixed. The hole also corresponds to the size of the bearing, so that the bearing on the shaft and the shaft forms a trapezoidal shape, and the holes on the wall of the fixed shaft and the bearing on the shaft also form a trapezoidal shape, and On each wall, each hole of the bearing is generally composed of a bearing hole and a limit ring. The bearing hole is generally in this trapezoid in this wall, the end of the larger end of the bearing hole, the limit The rings are all on one side of the smaller end of the bearing hole. This facilitates the installation of the shaft and facilitates the machining of the bearing holes on each wall in the body.

In the internal combustion engine, any shaft fixed to the machine body should be sealed with a cover plate as long as it has an opening on the outside of the machine body, as long as the shaft of the exposed body is sealed with an oil seal.

In the present internal combustion engine, the crankshaft may be integral; the crankshaft connecting rod journal and the crank may also be connected by holes and shafts (the holes and shafts may be various shapes such as a tapered shape and a cylindrical shape), with pins and screws. Fixed, it can also be fixed by thermal expansion and contraction, etc., so that bearings and connecting rods can be installed on the crankshaft connecting rod journal to make the rotation more sensitive and the friction is smaller.

The internal combustion engine can also be manufactured as a single-cylinder or multi-cylinder machine, or can be designed into an in-line type, a v-type, an opposite type, or the like, or can be manufactured into a gasoline engine, a diesel engine, or the like, or can be manufactured as a hand-operated micro gas oil machine. Can also be made into a song The principle of the internal combustion engine is also adapted to various external combustion engines and other types of engines, etc., which are also within the scope of the present invention.

Variations of the various techniques and various extensions of the techniques and techniques described above are within the scope of the invention.
