Description

Technical Field

[0001] The present invention relates to the technical field of engine cylinder blocks, and particularly to a high-heat combustion efficiency engine cylinder block. Background Art

[0002] An engine cylinder block, also known as an engine block, is the "skeleton" of an engine and a core component thereof. It is used to support and install mechanisms such as piston moving parts, and is convenient for providing a power source for the installed equipment.

[0003] The existing engine cylinder block includes a cylinder head and piston chambers opened inside. Reciprocating piston blocks are distributed in the piston chambers. A spark plug and a fuel pipe for feeding are installed on the cylinder head. The fuel pipe transports gasoline and air into the piston chambers in a certain proportion. Then, relying on the compression of the piston blocks, after the compression reaches a certain degree, the spark plug generates a spark to ignite the air-fuel mixture, causing the air-fuel mixture to burn instantaneously to generate high-pressure gas, pushing the piston blocks open to achieve power supply.

[0004] The deficiencies of the existing engine cylinder block are as follows: Although the existing engine cylinder block can compress the air-fuel mixture introduced into the piston chambers to a smaller volume and then rely on the spark plug to ignite it to achieve combustion and generate high-pressure gas to provide power, the gasoline and air are respectively transported into the piston chambers through pipes and cannot be well mixed only by the compression of the piston blocks. Because there is no good counter-flow mixing between gasoline and air, the mixing effect is average. And since the spark plug is generally arranged in the middle, the generated spark can only first ignite the mixture gas in the middle. However, the existing engine cylinder block is not convenient for effectively generating a higher concentration of air-fuel mixture near the spark plug and is not convenient for the transmission and combustion of the spark, resulting in an average combustion efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a high-heat combustion efficiency engine cylinder block to solve the technical problem that the existing engine cylinder block is not convenient for improving the combustion efficiency of the air-fuel mixture.

[0006] The technical problem to be solved by the present invention can be achieved through the following technical solutions:

[0007] A high-heat combustion efficiency engine cylinder block includes a cylinder block main body and a cylinder head. Multiple groups of mounting holes are distributed on the cylinder head. Each group of mounting holes includes a spark plug mounting hole and a fuel pipe connection hole. It further includes:

[0008] Auxiliary mixing mechanism, multiple groups of the auxiliary mixing mechanism are provided, and each group of the auxiliary mixing mechanism includes a frustum-shaped groove body, a piston sliding cylinder and a piston extrusion member. The frustum-shaped groove body is arranged at the bottom of the corresponding spark plug mounting hole. A plurality of piston sliding cylinders and piston extrusion members are provided and are circumferentially and equidistantly distributed around the frustum-shaped groove body. An air hole is formed on one side of each piston sliding cylinder close to the frustum-shaped groove body, and the piston extrusion member is correspondingly slidably arranged in the piston sliding cylinder;

[0009] Flame acceleration transmission mechanism, the flame acceleration transmission mechanism includes an elastic vibration piece and an impact mechanism. A plurality of elastic vibration pieces are circumferentially distributed at the bottom of each frustum-shaped groove body, and the elastic vibration piece is fixedly connected to the inner wall of the corresponding frustum-shaped groove body. An impact mechanism matched with the elastic vibration piece is fixedly arranged on the outer wall of each piston sliding cylinder.

[0010] As a further scheme of the present invention: the piston extrusion member includes a top rod and a first piston member. The first piston member is slidably arranged in the piston sliding cylinder, and the top rod is fixedly connected below the first piston member.

[0011] As a further scheme of the present invention: a plurality of air cavities are distributed around the frustum-shaped groove body. A second piston member slidably matched with the air cavity is fixedly connected to the top of each piston sliding cylinder. A stop ring for preventing the second piston member from disengaging from the air cavity is arranged at the bottom edge of the air cavity. An elastic limiting member for limiting the position of the second piston member is also arranged in the air cavity. An inclined hole matched with the elastic vibration piece is formed on one side of the air cavity close to the frustum-shaped groove body.

[0012] As a further scheme of the present invention: the elastic limiting member includes a limiting spring and a stopper. The stopper is attached to the upper surface layer of the second piston member, and the stopper is connected to the top of the air cavity through the limiting spring.

[0013] As a further scheme of the present invention: the impact member includes a strip-shaped metal plate and an extrusion ball. The strip-shaped metal plate is arranged in parallel on one side of the corresponding piston sliding cylinder close to the frustum-shaped groove body, and the bottom of the strip-shaped metal plate is fixedly connected to the piston sliding cylinder. A plurality of extrusion balls are arranged and are longitudinally and equidistantly distributed on one side of the strip-shaped metal plate. Each extrusion ball is matched with the corresponding elastic vibration piece.

[0014] As a further scheme of the present invention: a wavy sliding groove is formed on the inner wall of one side of the piston sliding cylinder close to the air hole. A universal ball member slidably matched with the wavy sliding groove is arranged on one side of the piston extrusion member. A guiding member for preventing the piston extrusion member from rotating is arranged between the piston extrusion member and the cylinder head.

[0015] As a further solution of the present invention: The universal ball member includes a ball shell and a rolling ball. The ball shell is cooperatively connected with the piston extrusion member. The rolling ball is movably fitted in the ball shell and is slidably cooperatively connected with the wavy chute.

[0016] As a further solution of the present invention: The guiding member includes a guide rod and a guiding channel. The guide rod is fixedly arranged on one side of the bottom of the piston extrusion member. The guiding channel is opened on the cylinder head, and the guide rod is slidably inserted into the guiding channel.

[0017] As a further solution of the present invention: The guiding channel communicates with the corresponding air chamber.

[0018] As a further solution of the present invention: An elastic telescopic rod is horizontally arranged between the universal ball member and the piston extrusion member.

[0019] Advantages of the present invention:

[0020] 1. When the piston block slides along the piston chamber to compress the mixture of gasoline and air in the present invention, due to the frustum-shaped groove provided at the bottom of the spark plug installation, it is convenient for the mixture to gather near the spark plug under the guidance of the frustum-shaped groove. At the same time, the piston block first exerts a squeezing effect on the piston extrusion member in the piston sliding cylinder, so that the mixture in the piston sliding cylinder is sprayed and counter-jet toward the middle through the air holes, improving the mixing effect. After the piston extrusion member is pressed to the top inside the piston sliding cylinder, as the piston block continues to squeeze, it will also cause the piston sliding cylinder to drive the second piston member to squeeze the mixture in the air chamber, so that the mixture in the air chamber is sprayed toward the frustum-shaped groove through the inclined holes, further improving the fuel-air mixing effect. At the same time, because it gathers near the spark plug, it is convenient for the spark plug to ignite, realizing efficient combustion. At the same time, due to the formation of a high-concentration mixture near the spark plug and maintaining lean combustion in the periphery, the thermal efficiency is improved and the knocking risk is reduced.

[0021] 2. When the piston sliding cylinder slides and rises relative to the air chamber in the present invention, the piston sliding cylinder also drives the strip-shaped metal plate to rise synchronously. The extrusion balls distributed on the strip-shaped metal plate squeeze through the elastic vibrating pieces one by one, causing the elastic vibrating pieces to vibrate. The elastic vibrating pieces rely on the vibration to accelerate the movement of the fuel-air mixture, so as to facilitate the spark generated by the spark plug to accelerate the transmission and diffusion along the fuel-air mixture, improving the combustion efficiency.

[0022] 3. The inclined holes in the present invention face the elastic vibrating pieces, which is convenient for the sprayed fuel-air mixture to impact on the vibrating elastic vibrating pieces. Combining with the vibration effect of the elastic vibrating pieces, the movement of the mixture is intensified, which helps the fuel-air mixture to be further mixed, thereby further improving the combustion efficiency.

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts fall within the protection scope of the present invention.

[0036] AsFigures 1 - 10 As shown in the figure, a cylinder block of an engine with high combustion efficiency includes a cylinder block main body 1 and a cylinder head 2. A plurality of piston chambers 5 are distributed in the cylinder block main body 1. Here, the piston chambers 5 are distributed according to the type of engine, such as a four-cylinder engine, a three-cylinder engine, etc. A reciprocating piston block 24 is arranged in the piston chamber 5, and the piston block 24 can achieve reciprocating motion by relying on a crank mechanism; a plurality of groups of mounting holes aligned with the piston chambers 5 are distributed on the cylinder head 2. Each group of mounting holes includes a spark plug mounting hole 3 and a fuel pipe connection hole 4. Among them, the fuel pipe connection hole 4 is divided into two channels, namely a channel for supplying gasoline and a channel for supplying air. The two channels are respectively connected to corresponding conveying pipe bodies 27, which facilitates the supply of gasoline and air into the piston chamber 5 in a corresponding proportion. Then, the piston block 24 moves upward to compress the air-fuel mixture. When the compression reaches a certain degree, the spark plug 26 installed in the spark plug mounting hole 3 generates a spark, igniting the air-fuel mixture and instantly generating a strong pressure to push the piston block 24 downward, thereby realizing power supply; the cylinder block of this engine also includes an auxiliary mixing mechanism and a flame acceleration and transmission mechanism;

[0037] A plurality of groups of auxiliary mixing mechanisms are provided and are distributed corresponding to the mounting holes. Each group of auxiliary mixing mechanisms includes a frustum-shaped groove body 7, a piston sliding cylinder 6, and a piston pressing member. The frustum-shaped groove body 7 is arranged at the bottom of the corresponding spark plug mounting hole 3, and the two are concentrically distributed. The diameter of the frustum-shaped groove body 7 gradually decreases from bottom to top. A plurality of piston sliding cylinders 6 and piston pressing members are provided and are circumferentially equidistantly distributed around the frustum-shaped groove body 7. An air hole 17 is opened on one side of each piston sliding cylinder 6 close to the frustum-shaped groove body 7, and the air hole 17 is close to the top position of the piston sliding cylinder 6. The piston pressing member is correspondingly slidably arranged in the piston sliding cylinder 6. After gasoline and air enter the piston chamber 5 through the corresponding fuel pipe connection hole 4, the piston block 24 moves upward to compress the air-fuel mixture. During this process, due to the compression effect, a part of the air-fuel mixture will enter the corresponding piston sliding cylinder 6 through the air holes 17 at various positions, and will also be gathered at the position where the spark plug 26 is located through the guidance of the frustum-shaped groove body 7, making the concentration near the spark plug 26 high and facilitating ignition. When the piston block 24 compresses upward to the corresponding position, it begins to squeeze the distributed piston pressing members, so that the piston pressing members squeeze the internal space of the piston sliding cylinder 6, facilitating the injection of the air-fuel mixture in the piston sliding cylinder 6 through the air holes 17 to the middle position below the spark plug 26, facilitating the further full mixing of the air-fuel mixture through the aggregation and counteracting effect, thereby facilitating full combustion and improving the combustion efficiency;

[0038] The flame acceleration transmission mechanism includes elastic vibration pieces 11 and an impact mechanism. A plurality of elastic vibration pieces 11 are circumferentially distributed at the bottom of each frustum-shaped groove body 7, and the elastic vibration pieces 11 are fixedly connected to the inner wall of the corresponding frustum-shaped groove body 7 through brackets. An impact mechanism that cooperates with the elastic vibration pieces 11 is fixedly arranged on the outer wall of each piston cylinder 6. The impact mechanism is used to impact the elastic vibration pieces 11, causing the elastic vibration pieces 11 to vibrate. As a result, the mixed gas gathered in the frustum-shaped groove body 7 accelerates its movement by relying on the vibration, facilitating the accelerated diffusion of the sparks generated by the spark plug member 26. Thus, it is convenient to increase the ignition speed of the mixed gas, improve the combustion efficiency, and at the same time, the vibration effect can further enhance the oil-gas mixing effect.

[0039] In some specific implementation schemes, such as Figure 6 shown, the piston extrusion member includes a push rod 8 and a first piston member 16. The first piston member 16 is slidably fitted in the piston cylinder 6, and the push rod 8 is fixedly connected below the first piston member 16. It should be noted that the frictional resistance between the first piston member 16 and the inner wall of the piston cylinder 6 is less than the gravity of the first piston member 16. When there is no extrusion effect of the piston block 24 on the push rod 8, the first piston member 16 can slide to the bottom of the piston cylinder 6 under the action of gravity. When the piston block 24 upwardly extrudes the push rod 8, the push rod 8 drives the first piston member 16 to slide and rise along the piston cylinder 6, and presses out the internal oil-gas mixture from the air hole 17.

[0040] In some specific implementation schemes, such as Figure 5 and Figure 6 shown, a plurality of air cavities 12 are distributed around the frustum-shaped groove body 7. A second piston member 28 that is slidably fitted with the air cavity 12 is fixedly connected to the top of each piston cylinder 6. The second piston member 28 is matched with the cross-sectional size of the air cavity 12, and a stop ring 19 for preventing the second piston member 28 from disengaging from the air cavity 12 is arranged at the opening edge of the bottom of the air cavity 12. An elastic limiting member for restricting the position of the second piston member 28 is also arranged in the air cavity 12. An inclined hole 25 that cooperates with the elastic vibration piece 11 is opened on one side of the top of the air cavity 12 close to the frustum-shaped groove body 7.

[0041] Among them, the elastic limiting member includes a limiting spring 13 and a stop block 14. The stop block 14 is attached to the upper surface layer of the second piston member 28, and the stop block 14 is connected to the inner top of the air cavity 12 through a compressible limiting spring 13.

[0042] When the piston block 24 exerts a squeezing action on the ejector rod 8, the ejector rod 8 drives the first piston member 16 to slide and rise relative to the piston slide cylinder 6, facilitating the pressing out of the mixed gas in the piston slide cylinder 6 from the air hole 17. During this process, the stop block 14 presses on the second piston member 28 to prevent the piston slide cylinder 6 from sliding and rising relative to the air chamber 12. When the first piston member 16 slides to the top inside the piston slide cylinder 6 and is blocked, the piston block 24 exerts a squeezing action on the piston slide cylinder 6, and the piston slide cylinder 6 drives the second piston member 28 to slide and rise along the air chamber 12, and the stop block 14 compresses the limit spring 13. Since there will also be a part of the oil-gas mixture entering the air chamber 12 through the inclined hole 25 when the piston block 24 compresses the oil-gas mixture in the piston chamber 5, when the second piston member 28 compresses the space in the air chamber 12 upward, the existing oil-gas mixture can be ejected through the inclined hole 25 and sprayed onto the corresponding elastic vibration piece 11, and the elastic vibration piece 11 makes the sprayed oil-gas mixture further accelerate and spread through vibration, which is beneficial to mixing and at the same time facilitates the transmission and ignition of the spark generated by the spark plug member 26, improving the ignition efficiency.

[0043] In some specific embodiments, such as Figure 6 As shown, the impact member includes a strip-shaped metal plate 10 and a pressing ball 18. The strip-shaped metal plate 10 is arranged in parallel on one side of the corresponding piston slide cylinder 6 close to the frustum-shaped groove body 7, and the bottom of the strip-shaped metal plate 10 is fixedly connected to the piston slide cylinder 6 through a cross bar. The strip-shaped metal plate 10 is aligned with the edge of the top position of the frustum-shaped groove body 7. A plurality of pressing balls 18 are provided and longitudinally arranged at equal intervals on one side of the strip-shaped metal plate 10. Each pressing ball 18 cooperates with the corresponding elastic vibration piece 11. It should be noted that the strip-shaped metal plate 10 can also be made of elastic metal.

[0044] When the piston slide cylinder 6 slides and rises along the air chamber 12, it will also drive the strip-shaped metal plate 10 to rise. During the rising process of the strip-shaped metal plate 10, the distributed pressing balls 18 it drives pass through the elastic vibration piece 11 one by one. When each pressing ball 18 passes, it will cause the elastic vibration piece 11 to be squeezed and deformed. After the pressing ball 18 passes, the elastic vibration piece 11 rebounds to produce a reset. Repeating like this will generate vibration.

[0045] In some specific embodiments, in order to facilitate the further effective mixing of gasoline and air, in combination with Figures 6 - 8 As shown, a wavy chute 20 is provided on the inner wall of one side of the piston slide cylinder 6 close to the air hole 17. A universal ball member that slides in cooperation with the wavy chute 20 is provided on one side of the piston pressing member. The piston slide cylinder 6 and the air chamber 12 are both cylindrical structures, facilitating the rotation of the piston slide cylinder 6; a guiding member for preventing the piston pressing member from rotating is provided between the piston pressing member and the cylinder head 2.

[0046] Among them, the universal ball part includes a ball shell 22 and a rolling ball 23. The ball shell 22 is connected to the piston extrusion part in a cooperative manner, specifically, it can be connected to the ejector rod 8. The rolling ball 23 is movably fitted inside the ball shell 22, and the rolling ball 23 is in sliding fit connection with the wavy chute 20.

[0047] In addition, the guiding part includes a guide rod 9 and a guiding channel 15. The guide rod 9 is fixedly arranged on one side of the bottom of the piston extrusion part. Specifically, a disc can be fixedly installed at the bottom of the ejector rod 8, and then the bottom of the guide rod 9 is fixedly connected to the ejector rod 8 through the disc. The guiding channel 15 is opened on the cylinder head 2, and the guide rod 9 slides through the guiding channel 15.

[0048] When the piston extrusion part slides and rises along the piston sliding cylinder 6, the arranged rolling ball 23 rises along with the piston extrusion part. During this process, the rolling ball 23 slides along the wavy chute 20. Since the piston sliding cylinder 6 can rotate relative to the air chamber 12, while the piston extrusion part itself is limited by the guide rod 9 and cannot rotate, during this process, with the change of the shape of the wavy chute 20, the piston sliding cylinder 6 will perform a reciprocating swing at a certain angle. And during this process, because the piston extrusion part compresses the mixed gas in the piston sliding cylinder 6 and makes it spray out from the air hole 17, during the reciprocating swing of the piston sliding cylinder 6, the gas spraying range can be increased, further promoting the mixing effect.

[0049] In some specific implementation schemes, the guiding channel 15 is communicated with the corresponding air chamber 12, and the cross-sectional diameter of the guiding channel 15 is much smaller than the diameters of the air chamber 12 and the inclined hole 25, which is convenient for ensuring that the gas in the air chamber 12 is sprayed out from the inclined hole 25 as much as possible when being pressed out, and avoiding excessive entry into the guiding channel 15. At the same time, since the guiding channel 15 is communicated with the air chamber 12, it means that it is also communicated with the internal space of the piston chamber 5, thus facilitating the sliding of the guide rod 9 and avoiding affecting the sliding.

[0050] In some specific implementation schemes, in order to ensure that the rolling ball 23 always fits and docks in the wavy chute 20, an elastic telescopic rod 21 is horizontally arranged between the universal ball part and the piston extrusion part. The elastic telescopic rod 21 is composed of a telescopic rod body and a spring sleeved on the telescopic rod body. Specifically, one end of the elastic telescopic rod 21 can be fixedly connected to the ejector rod 8, and the other end is fixedly connected to the ball shell 22. During the process of the rolling ball 23 sliding along the wavy chute 20, the elastic telescopic rod 21 can always keep the rolling ball 23 fitting different positions of the wavy chute 20 by relying on the resilience force.

[0051] It should be noted that, in order to facilitate the piston sliding cylinder 6 to perform a reciprocating rotational swing after sliding and rising relative to the air chamber 12, a plurality of balls can be distributed in a circle at the bottom of the second piston part 28, and the balls contact the stop ring 19, which is convenient for the second piston part 28 to rotate on the stop ring 19.

[0052] For the convenience of those skilled in the art to understand the embodiments of this solution, the working principle of this solution will be briefly described below in combination with a specific application scenario:

[0053] When the cylinder head 2 and the engine cylinder block 1 are docked and used together, gasoline and air are transported into the piston chamber 5 through the corresponding delivery pipe bodies 27 and the fuel pipe connection holes 4 according to the corresponding ratio. The piston block 24 in the piston chamber 5 is driven by the crank mechanism to move upward to compress the air-fuel mixture. During this process, due to the compression effect, a part of the air-fuel mixture will enter the corresponding piston slide cylinder 6 through the air holes 17 at various positions, and is also guided by the frustum-shaped groove body 7 and gathered at the position where the spark plug part 26 is located, so that the concentration near the spark plug part 26 is high;

[0054] And when the piston block 24 is compressed upward to the corresponding position, it starts to squeeze the push rod 8. The push rod 8 drives the first piston part 16 to slide and rise along the piston slide cylinder 6, and presses out the internal air-fuel mixture from the air hole 17, which is convenient for the air-fuel mixture in the piston slide cylinder 6 to be sprayed from the air hole 17 to the middle position below the spark plug part 26, facilitating the full mixing of the air-fuel mixture through the middle impact effect;

[0055] During the process of the push rod 8 driving the first piston part 16 to slide and rise along the piston slide cylinder 6, the arranged rolling ball 23 rises synchronously with the push rod 8 and the first piston part 16. During this process, the rolling ball 23 slides along the wavy chute 20. Since the piston slide cylinder 6 can rotate relative to the air chamber 12, and the push rod 8 and the first piston part 16 are limited by the guide rod 9 and cannot rotate themselves, during this process, with the shape change of the wavy chute 20, the piston slide cylinder 6 will perform a reciprocating rotational swing at a certain angle. And during this process, because the first piston part 16 compresses the mixed gas in the piston slide cylinder 6 and makes it spray out from the air hole 17, during the reciprocating rotational swing of the piston slide cylinder 6, the gas spraying range can be increased, further promoting the mixing effect.

[0056] It should be noted that when the push rod 8 drives the first piston part 16 to slide and rise relative to the piston slide cylinder 6, the stopper 14 presses on the second piston part 28 to prevent the piston slide cylinder 6 from sliding and rising relative to the air chamber 12. When the first piston part 16 slides to the top inside the piston slide cylinder 6 and is blocked, the piston block 24 exerts a squeezing effect on the piston slide cylinder 6, and the piston slide cylinder 6 drives the second piston part 28 to slide and rise along the air chamber 12, and makes the stopper 14 compress the limit spring 13. Since when the piston block 24 compresses the air-fuel mixture in the piston chamber 5, a part of the air-fuel mixture will also enter the air chamber 12 through the inclined hole 25, when the second piston part 28 compresses the space in the air chamber 12 upward, the existing air-fuel mixture can be sprayed out through the inclined hole 25 and sprayed onto the corresponding elastic vibration piece 11;

[0057] When the piston slide cylinder 6 slides and rises along the air cavity 12, it will also drive the strip-shaped metal plate 10 to rise. During the rising process of the strip-shaped metal plate 10, it drives the distributed extrusion balls 18 to pass through the elastic vibration pieces 11 one by one. When each extrusion ball 18 passes, it will cause the elastic vibration piece 11 to be extruded and deformed. After the extrusion ball 18 passes, the elastic vibration piece 11 will rebound to reset. Repeating this way will generate vibration. The elastic vibration piece 11 relies on the vibration to further accelerate the diffusion of the injected oil-gas mixture, which is beneficial to mixing and the formation of turbulence of the oil-gas mixture, facilitating the rapid transmission of the spark generated by the spark plug part 26 to ignite the compressed oil-gas mixture, thereby improving the ignition efficiency.

[0058] The above has described several embodiments of the present invention in detail, but the embodiments of the present invention are not limited thereto and should not be considered as defining the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
