Description

Multi-track rotor type internal combustion engine

Technical field

The present invention relates to an internal combustion engine, and more particularly to a rotary internal combustion engine.

Background technique

In the field of internal combustion engines, the reciprocating crank-link internal combustion engine is widely used. Since the invention of the German inventor Otto in 1876, the technology has become more and more mature. The working principle is to use the expansion force generated by the combustion of the combustible gas in the closed space formed by the cylinder and the piston to push the piston to reciprocate linearly in the cylinder, and the kinetic energy is converted into the rotary kinetic energy output application through the crank linkage mechanism. The advantages of this type of internal combustion engine are good sealing and lubrication performance and reliable operation. Disadvantages are the large inertia impact force of the reciprocating motion of the piston and its connecting parts, the large vibration caused by the ignition of the dead point, the short length of the connecting rod, the low efficiency of the arm and the complicated structure. Another disadvantage of this type of internal combustion engine is the advancement. The gas is not smooth enough, and the intake and exhaust devices have numerous parts and complicated structure. The intake and exhaust valves are installed at the closed end of the cylinder, and the area is limited to the diameter of the piston. In this narrow space, the exhaust valve and the spark plug should be placed, so that The diameter of the intake and exhaust valves is limited, the intake and exhaust are very fast, the air can not be smoothly taken in and the residual gas after combustion is completely eliminated, resulting in incomplete combustion and the discharge is not up to standard. Although it has been improved by adopting technical measures such as resetting multiple valves and opening and exhausting valves in advance, the effect is still not satisfactory.

In modern times, people have invented the rotor type internal combustion engine through continuous exploration and innovation, especially the Wankel internal combustion engine that has been put into use, which provides a direction for the development of the rotor type internal combustion engine. However, due to the shortcomings of the Wankel internal combustion engine, such as poor sealing and high fuel consumption, It has not yet been widely used.

China's State Intellectual Property Office has announced a variety of rotor-type internal combustion engine design, but the various rotor-type internal combustion engines involved also have short intake and exhaust times, poor sealing effect and the rotor cooling and lubrication can not be effectively solved.

Summary of the invention

The present invention provides a multi-track rotor type internal combustion engine to solve the above problems.

The linear motion of the piston is converted into a rotary motion by using the cylinder and the piston to rotate with the rotor and the piston moves along a specific curved path to solve the technical problem of large vibration and short arm of the reciprocating crank connecting rod engine; use in the middle of the rotor and the end cover The way of sealing device solves the technical problem of sealing between each other; the technical problem of complicated inlet and exhaust and complicated structure of parts is solved by providing air passage on the rotor and providing air inlet and exhaust passage on the end cover; The utility model solves the technical problem that the residual gas in the cylinder is cleaned by using the scavenging hole on the end cover; the cooling lubrication and the power transmission of the rotor, the cylinder, the piston and the like are solved by setting the cooling lubrication and the power passage on the main shaft. Technical problem; the technical problem of smooth ignition when the rotor rotates is solved by installing the spark plug on the rotor.

The following technical solutions are being developed to solve the above technical problems:

The multi-track rotor type internal combustion engine of the present invention is composed of a stator, a rotor, a main shaft, a front end cover, a rear end cover, a plurality of front and rear auxiliary end covers, and a pulley assembly.

The stator is provided with a concave or convex road around the center of the main shaft. When the slide rotates along the slide, the distance from the center of the slide is close to and away from the center of the spindle. The difference is the size of the piston stroke; the slide is from inside. The combination of the slide rail and the outer slide rail has a specific curve, and the specific curve may be a circumferential line, which may be an elliptical line, or a wavy line or other curves that are close to the center of the spindle when approaching; The pulley assembly is composed of an inner pulley, an outer pulley and a guide slider. When the rotor rotates, the inner and outer pulleys drive the piston to move closer to or away from the center of the spindle along the inner and outer slide rails. During the suction stroke, the inner pulley rotates clockwise along the inner slide rail to drive the piston away from the center of the spindle to take in air; when the clockwise rotation continues, the outer pulley bears against the outer slide rail to drive the piston to approach the center of the spindle to compress the sucked air; After ignition and combustion, the high-pressure gas pushes the piston to move outward. The outer pulley connected to the piston rotates clockwise around the outer slide rail and moves away from the center of the spindle to complete the power stroke; the clockwise rotation continues, and the outer pulley bears against the outer slide rail to make the piston The center of the spindle is close, and the exhaust gas in the cylinder is exhausted to complete the exhaust stroke.

A guide slide on the pulley assembly is disposed adjacent to both sides of the inner slide rail for controlling the sliding direction of the pulley assembly and preventing the piston from rotating freely within the cylinder.

A cylinder is mounted on the rotor, and is assembled and integrated with the main shaft by a static fit and a double key. The cylinders installed on the rotor can be divided into single or multiple rows. The centerline of each cylinder is perpendicular to the centerline of the spindle and maintains an appropriate distance from the centerline of the spindle. The appropriate distance is a minimum of 30 mm and a maximum of 5800 mm. One end of the cylinder In the open type, the piston is loaded by the open cylinder port and the other end is the closed end. The angle between the centerlines of each cylinder is evenly set according to the circumference. The calculation formula is 360° divided by the number of cylinders installed in the rotor. When the cylinder is 2 rows and 2 cylinders per row, the angle between the centerlines of each cylinder is At 90°, there is one cylinder for each rotation of the rotor, and the rotor works four times for each revolution of the rotor.

The intake and exhaust stroke of the multi-track rotor type internal combustion engine is completed by the cooperation of the rotor and the end cap. A closed circular or elliptical opening is provided at a closed end of the cylinder mounted on the rotor near the front and rear end caps, and a position of the joint between the front and rear end caps along the rotor air passage return line to the end of the exhaust end and the intake state is started. There is a circular ribbed scavenging hole, the anti-clockwise direction of the scavenging hole is provided with an exhaust passage penetrating through the rib plate, a clockwise direction of the scavenging hole is arranged to close the intake port, and a circular ribbed plate is arranged at the end of the intake air. The through hole is an air inlet hole. The scavenging hole is not in communication with the intake port and the exhaust passage, and the first baffle is provided at the connection with the exhaust passage, and the second baffle is provided at the connection with the intake passage; when the rotor rotates to the exhaust start position, the rotor The air passage provided on the upper end communicates with the exhaust passage on the end cover to start exhausting; when the air is rotated to the position of the scavenging hole, the air detecting hole communicates with the exhaust passage, and the compressed air in the air detecting hole enters the air passage from the first blocking side. At this time, the compressed air pressure entering the air passage is greater than the residual gas pressure in the air passage which is close to the exhaust end, and the residual gas in the cylinder is quickly blown out to the exhaust passage along the other side of the first partition; the rotation continues to the air passage and When the scavenging hole is completely coincident, the scavenging hole is not in communication with the intake port and the exhaust passage, and the exhausting is completed; when the rotation continues to the intake port position, the air is sucked in, the injector is injected with oil, and the intake stroke is started. When the air intake is reached, the intake air ends. The front and rear end caps are mirror images of each other, and are thicker plate-shaped, and are mounted on the main shaft by a thrust bearing; or may be made into a hemispherical shape, an arc shape or a special shape with a rib plate connected to the sub-end cover, Make sure you can withstand the enormous pressures that can occur when a flammable gas bursts out of the airway.

The sealing ring is sealed between the rotor and the end cover. There are 6 sealing rings on each end face, two outer sealing rings, two inner sealing rings and two air passage sealing rings. Two airway seal ring grooves are formed on the rotor around the air passage at the air passage position of each cylinder, and two outer seal ring grooves are formed on the rotor around the center of the air shaft on the outer side of the air passage seal ring groove, on the inner side of the air passage seal ring groove. Two inner seal ring grooves are formed on the rotor around the center of the main shaft, and annular ring-shaped springs and seal rings are placed in each ring groove, all of which are circular and have a disconnecting port, and the radial section is rectangular; When the multi-track rotor type internal combustion engine is running, the annular wave spring placed at the bottom of each sealing ring groove ejects the sealing ring toward the end cover, so that it closes the end cover to seal the air passage; the inner sealing ring disposed on both sides of the air passage The outer seal ring and the outer seal ring are secondarily sealed to prevent the exhaust gas from entering the slide rail and the main shaft.

Five long holes are opened along the center line of the main shaft, two of which are cooling water passages, two holes are power passages, and one hole is a lubricating oil passage. The oil inlet of the lubricating oil passage is respectively disposed at the front and rear end caps and the rotating position of the main shaft, and the oil outlet is set at an appropriate position of the rotor to communicate with the inner oil passage of the rotor, and is respectively connected to each cylinder for lubrication and cooling; the two power passages respectively Radially symmetrically placed along the main axis, power is fed into the rotor for spark plug ignition; when fuel is used for diesel, the two power channels can be omitted. The two cooling water passages are water inlets and outlets symmetrically arranged along the main axis of the same diameter, respectively communicating with each other at the position of the inlet and outlet of the front and rear auxiliary end caps along the radial opening of the main shaft, through the cooling water inlet. The opening and passage in the rotor flow into the cylinder cooling water jacket to cool the cylinder, and then flow out from the main shaft cooling water outlet through the opening and passage in the rotor; the front and rear end caps can open the inlet and outlet at appropriate positions to cool the exhaust passage .

In order to fully and comprehensively express the present invention, the relevant nouns and conventions involved are as follows:

Full journey

As shown in Fig. 3E, the distance between the B-end and the D-end of the slide is greater than the distance between the end of the spindle and the center of the C-axis from the center of the spindle. It can be further understood that the slide on the stator is wavy along the circumference of the main shaft. For the peak, Edin is a trough. The entire stroke of a single cylinder rotating in the 360° range and undergoing two peaks and two valleys to complete one inhalation, compression, work, and exhaust is called 1 full stroke, and the rotation in the 360° range is experienced in four cycles. The crest and the four troughs complete two inhalations, The total stroke of compression, work, and exhaust is called 2 full strokes, and so on, there can be 3 or even N full strokes, and the total stroke number is actually the number of times that a single cylinder works in the 360° range.

According to this principle, when the stroke of the piston is constant, more full stroke can be set on the circumference of the stator when the diameter of the rotor is increased; after the diameter of the rotor is increased, the number of cylinders can be increased on the rotor. At the same time as the boom, the power of a single internal combustion engine is greatly increased.

2. The number of rotors

The number of rotors of each internal combustion engine can be set to 1, 2 or even N.

3. Number of cylinders

As shown in Fig. 2, Fig. 19, Fig. 20, and Fig. 23, one row of cylinders, two rows of cylinders, or even N rows of cylinders can be established in one rotor radial range.

4. The number of cylinders

The number of cylinders per row can be set to 1, 2 or even N.

The "N" of the above items is a range of a natural integer of 3 to 100.

According to the above agreement, the rotor design parameters of the multi-track rotor type internal combustion engine are expressed as follows:

Rotor diameter × number of rotors × number of rows of single rotor cylinders × number of cylinders per row × total number of strokes

For example, the diameter of the rotor is 300 mm, one rotor, two rows of cylinders per rotor, two cylinders per row, and one full stroke are expressed as follows: Φ300×1×2×2×1.

5. As mentioned above, the "appropriate distance" in the "center line of each cylinder is perpendicular to the center line of the main shaft and at an appropriate distance from the center line of the main shaft" is as follows:

The appropriate distance is the closest distance between the cylinder centerline and the spindle centerline when the cylinder centerline coincides with the intersection of the spindle centerline and the stator outer rail line. As shown in Fig. 22, the appropriate distance is the distance between two points A and B.

The appropriate distance can change the direction of the axial force of the piston, so that the direction of the axial force of the piston changes with the angle of the external tangential line of the outer rail, which has an effect on the torque. Under the same force, the appropriate distance is larger. The greater the angle between the direction in which the axial force of the piston is running and the tangent to the outer rail, the greater the torque. The appropriate distance can be as small as 30 mm and up to 5800 mm.

According to the above description and convention, the present invention can be flexibly designed into various combinations according to actual requirements such as power, rotational speed and torque, such as different rotor diameters, different rotor numbers, different cylinder rows, and different cylinder numbers. Different or a combination of different full-stroke numbers to meet the wide-ranging needs of different power sources in various fields.

Compared with the reciprocating crank-link internal combustion engine currently in common use, the present invention has the following distinctive features:

1. Smooth operation and small vibration. Since the linear inertial kinetic energy of the piston is converted into the rotational inertia kinetic energy, and the symmetrical design of the rotating cylinder runs smoothly and the vibration is small, the number of revolutions of the internal combustion engine can be greatly reduced, and energy saving and emission reduction can be achieved.

2. Torque increases power. Compared with the reciprocating crank connecting rod internal combustion engine, the rotor diameter of the multi-track rotor type internal combustion engine is not limited, and the rotor diameter can be freely set in the range of 100 mm to 12000 mm as needed; The rotor diameter allows for a longer force arm, which increases the rotational torque and thus greatly increases the power of the single unit.

3. The design of opening the intake passage, the exhaust passage and the scavenging hole on the side of the end cover is adopted. Compared with the prior art, there are three obvious advances: first, the intake and exhaust are unobstructed, and the intake and exhaust passages of the present invention are designed. The cross-sectional area is much larger than the cross-sectional area of the reciprocating crank-link engine valve, which makes the intake and exhaust air very smooth, especially for improving the engine speed and further improving the power. Secondly, the design of the scavenging hole is added and compressed. The powerful purging of the air can make the residual gas in the cylinder nearly zero, the next combustion is more complete, the discharge is cleaner, and the pollution to the environment is reduced. Third, the intake and exhaust valves, cams and valve lifters are eliminated. The gas control system makes processing easier and reduces manufacturing costs.

4. Helps reduce carbon dioxide gas emissions. From the data of the model test (see Fig. 18), the multi-track rotor type internal combustion engine is subjected to the same pressure as the reciprocating crank-link internal combustion engine, and the torque can be increased by 2.43 times under the same displacement and the same piston stroke, namely: When the output of the internal combustion engine is constant, the displacement of the internal combustion engine can be greatly reduced. Conducive to the development of a low-carbon economy.

The multi-track rotor type internal combustion engine manufactured by the invention can be applied to road, railway or waterway transportation as a power source, and can be widely applied in other fields, and has great economic benefits.
