Detailed Description

Example (b):

the existing internal combustion engine has a complex structure and a plurality of contained systems, and because the working conditions are severe, the systems need to be precisely coordinated to realize the normal operation of the internal combustion engine, and the high-speed moving part has the characteristics of complex structure, high structural strength, wear resistance and high temperature resistance. Therefore, on the basis of the complicated structure of the existing internal combustion engine, the problems of relatively high failure rate and difficult maintenance are caused by the complicated structure, and the improvement and redesign of the existing internal combustion engine structure are needed to overcome the problems.

As shown in fig. 1-8, an internal combustion engine comprises a stator 1, a rotor 2, an ignition system 3 and a fuel supply system 4, wherein the concepts of the stator 1 and the rotor 2 are taken from the electric motor 41 or the generator, i.e. when the internal combustion engine is in operation, the stator 1 is kept relatively stationary and the rotor 2 is rotated relatively. The ignition system 3 generates an electric spark and ignites the fuel, thereby causing the fuel to work externally. The fuel supply system 4 continuously supplies fuel to continuously apply work to the outside.

The connection relationship of the present internal combustion engine is explained below: the rotor 2 is rotatably arranged in the stator 1, a driving structure is arranged between the rotor 2 and the stator 1, an ignition end of the ignition system 3 is fixed on the stator 1 and extends to the driving structure, the fuel supply system 4 supplies fuel to the driving structure through the stator 1, and the ignition system ignites the fuel to enable the driving structure to do work and drive the rotor 2 to rotate in the stator 1.

In operation, the fuel supply system 4 supplies fuel to the driving structure, the ignition system 3 ignites the fuel, and the fuel does work outwards and drives the rotor 2 to rotate in the stator 1. Meanwhile, the rotor 2 does work outwards, so that the internal combustion engine outputs mechanical work outwards to drive the driven machine to work.

Taking the existing reciprocating piston type internal combustion engine as an example for comparison, the working principle of the reciprocating piston type internal combustion engine is as follows: the piston type internal combustion engine mixes fuel and air and burns in a cylinder of the engine, and the released heat energy enables the cylinder to generate high-temperature and high-pressure fuel gas. The gas expands to push the piston to do work, and then the mechanical work is output through a crank-link mechanism or other mechanisms.

Then, from the energy transfer point of view, in the reciprocating piston type internal combustion engine, the heat energy released by the fuel is transferred to a driven machine after the secondary transmission of the piston and the crank-connecting rod mechanism; in the internal combustion engine, the heat energy released by the fuel can be transferred to the driven machinery through the rotor 2, so that the transmission stage number is reduced, the loss is reduced, and the use efficiency of the fuel is improved.

From the point of view of motion, the pistons in a reciprocating piston engine transmit mechanical work by reciprocating sliding, while the rotor 2 in this engine transmits mechanical work by rotation. Namely, the piston and the crank connecting rod mechanism in the reciprocating piston type internal combustion engine both need to move at high speed, and only the rotor 2 in the internal combustion engine needs to move at high speed, so that the internal combustion engine reduces the number of high-speed moving parts and is beneficial to reducing the failure rate. Meanwhile, the structure of the crank connecting rod mechanism is relatively complex, the mechanism is omitted, and the structure is simplified.

Structurally, the reciprocating piston type internal combustion engine comprises a shell, a piston and a crank connecting rod mechanism are arranged in the shell, a stator 1 in the internal combustion engine is equivalent to the shell, a rotor 2 is equivalent to the combination of the piston and the crank connecting rod mechanism in the reciprocating piston type internal combustion engine, and mechanisms such as ignition, fuel supply, cooling, lubrication and the like are respectively arranged outside the shell and the stator 1. The internal combustion engine greatly simplifies the structure, saves a power transmission part, directly outputs power and improves the efficiency.

In addition, when the reciprocating piston type internal combustion engine needs to increase the external output power, the adopted scheme is to increase the number of pistons, so that the volume of the shell is greatly increased, therefore, the conventional internal combustion engine is generally large and heavy in whole volume, quite troublesome in assembly and transportation, and increased in production cost. The internal combustion engine can be realized by increasing the number of the driving structures on the peripheral surface of the rotor 2 without increasing the volume of the stator 1, thereby effectively avoiding overlarge volume and being convenient for assembly and transportation.

The operation of the present internal combustion engine will now be further described with reference to specific configurations of drive configurations, including, but not limited to:

the driving structure comprises a groove body 21 positioned on the rotor 2 and a sliding block 11 positioned on the stator 1, wherein the groove body 21 is positioned on the outer peripheral surface of the rotor 2 and is inwards recessed, the sliding block 11 can slide in a reciprocating manner along the radial direction of the stator 1, and a feeding hole communicated with the fuel supply system 4 and an exhaust hole communicated with the outside are respectively arranged on two sides of the sliding block 11.

The sliding block 11 is inserted in the groove body 21 and divides the groove body 21 into a combustion chamber 211 and an exhaust chamber 212 which are not communicated with each other, at least part of the bottom of the exhaust chamber 212 is gradually inclined upwards along the rotation direction of the rotor 2 and is connected with the peripheral surface of the rotor 2, the feeding hole is communicated with the combustion chamber 211, the exhaust hole is communicated with the exhaust chamber 212, and the ignition end of the ignition system 3 is fixed on the stator 1 and extends into the combustion chamber 211.

When the internal combustion engine works, the sliding block 11 is inserted into the groove body 21 to separate the combustion chamber 211 and the exhaust chamber 212, and the combustion chamber 211 and the exhaust chamber 212 are respectively surrounded by the side wall of the groove body 21, the side surface of the sliding block 11 and the inner circumferential surface of the stator 1. Meanwhile, in order to improve the efficiency of the internal combustion engine, the combustion chamber 211 should be sealed, two sealing rings 201 are arranged on the outer circumferential surface of the rotor 2, the groove body 21 is located between the two sealing rings 201, and the stator 1 is provided with a sealing groove 103 adapted to the sealing rings 201. Therefore, the fuel leakage and the fuel gas leakage after the fuel is ignited are reduced, the part of the fuel gas for pushing the rotor 2 to rotate is improved, and the fuel utilization rate is further improved.

The fuel supply system 4 injects fuel into the combustion chamber 211 through the feed hole, the ignition system 3 ignites the fuel and generates high-temperature and high-pressure fuel gas, the pressure in the combustion chamber 211 is rapidly increased, and the rotor 2 is rotatable, so that the fuel gas pushes the rotor 2 to rotate, the volume of the combustion chamber 211 is gradually increased, and the pressure in the combustion chamber 211 is reduced. When the volume of the groove 21 is constant and the volume of the combustion chamber 211 increases, the volume of the exhaust chamber 212 decreases, and the slide block 11 rotates in the direction of the exhaust chamber 212 with respect to the rotor 2.

After the rotor 2 rotates a certain angle, the gas in the combustion chamber 211 becomes low-temperature and low-pressure exhaust gas. The sliding block 11 can slide along the radial direction of the stator 1, and the bottom of the exhaust chamber 212 is modified to be gradually inclined upwards along the rotation direction of the rotor 2, so as to ensure that the sliding block 11 can slide out. Referring to fig. 6, when the rotor 2 rotates, the sliding blocks 11 gradually approach the end of the exhaust chamber 212 in the circumferential direction, and the sliding blocks 11 gradually move away from the rotor 2 in the radial direction. After the sliding block 11 slides out of the groove body 21, the combustion chamber 211 in the groove body 21 is communicated with the exhaust chamber 212, and the exhaust gas flows into the exhaust chamber 212.

After the rotor 2 rotates for a circle, the sliding block 11 is inserted into the groove body 21 again, the groove body 21 is divided into the combustion chamber 211 and the exhaust chamber 212 again, and the above process is repeated to realize the continuous rotation of the rotor 2. At this time, the exhaust chamber 212 stores exhaust gas generated by the combustion of the previous batch of fuel, and the exhaust gas is exhausted through the exhaust hole. And when the rotor 2 rotates, the sliding blocks 11 are kept relatively stationary in the circumferential direction, the volume of the exhaust chamber 212 gradually decreases, and the exhaust of the exhaust gas is further accelerated.

Then, when the combustion chamber 211 is expanded to apply work, the slide block 11 discharges the exhaust gas generated after the last ignition combustion through the exhaust hole, and the fuel supply system 4 supplies fuel into the combustion chamber 211, the internal combustion engine can be divided into three strokes: an intake stroke (i.e., fuel supply system 4 supplies fuel into combustion chamber 211), a power stroke (i.e., ignition system 3 ignites to expand and apply work to the combustion chamber 211), and an exhaust stroke (i.e., exhaust gas in exhaust chamber 212 is exhausted through an exhaust port). And the three strokes can be completed in the same step, so the internal combustion engine can be called a one-stroke internal combustion engine.

The existing internal combustion engine is two-stroke or four-stroke, one working cycle is long in duration, heat energy is dissipated much, energy loss among moving parts is not little due to friction, and therefore the efficiency of the whole engine is low and is between 28 and 40 percent. The internal combustion engine effectively overcomes the problem, improves the efficiency and improves the utilization rate of fuel. In other words, the fuel with the same volume can be used for a longer time, the purposes of energy conservation and emission reduction are achieved, the use cost is reduced, and the economic benefit and the social benefit of the internal combustion engine are reflected.

Optionally, the exhaust pipe 101 is inserted into the exhaust hole to prevent the exhaust gas from directly contacting the exhaust hole, thereby reducing corrosion on the exhaust hole.

In a possible implementation manner, as shown in fig. 5, the sliding block 11 includes a bracket 111 fixed on the outer peripheral surface of the stator 1, a sliding rod 112 slidably disposed on the bracket 111, an elastic member 113 sleeved on the sliding rod 112, and a sliding block body 114 connected to the sliding rod 112, where the sliding block body 114 is disposed on the stator 1 in a penetrating manner, the sliding rod 112 and the sliding block body 114 are both disposed along the radial direction of the stator 1, one end of the elastic member 113 abuts against the bracket 111, and the other end of the elastic member 113 abuts against the sliding block body 114.

Specifically, the bracket 111 provides a mounting fulcrum, and the sliding rod 112 guides the sliding of the slider body 114; the elastic piece 113 helps to realize the reset of the slider body 114, so that the automation degree is improved; the slider body 114 passes through the stator 1 and abuts against the rotor 2, thereby realizing the separation of the slot body 21 and the exhaust emission. Accordingly, the stator 1 is provided with a groove-like structure adapted to the slider body 114.

When the slider body 114 is inserted into the groove body 21, the groove body 21 is partitioned into the combustion chamber 211 and the exhaust chamber 212. As the rotor 2 rotates, the slider body 114 will gradually slide out of the slot 21, that is, the slider body 114 will slide in the radial direction, the slider body 114 gradually moves away from the rotor 2 and gradually approaches the bracket 111, at this time, the sliding rod 112 slides along with the slider body 114, and the elastic member 113 is compressed. When the slider body 114 abuts against the outer peripheral surface of the rotor 2, the slider body 114 stops sliding; when the rotor 2 rotates to make the slot 21 below the slider body 114 again, the slider body 114 slides towards the rotor 2 under the elastic force of the elastic member 113 and is inserted into the slot 21 again.

Alternatively, the bracket 111 may be configured in any suitable shape and the resilient member 113 includes, but is not limited to, a spring.

Optionally, a positioning piece 115 is further disposed between the sliding rod 112 and the slider body 114, the sliding rod 112 passes through the positioning piece 115 and is connected to the slider body 114, and accordingly, two ends of the elastic member 113 abut against the bracket 111 and the positioning piece 115 respectively. Based on the design, on one hand, the cross section of the positioning piece 115 is larger, so that the elastic piece 113 can be abutted conveniently; on the other hand, the locating plate can be matched with the ignition system 3 to ignite in time by utilizing the in-place signal of the reciprocating sliding action of the locating plate 115.

In a possible implementation, the ignition system 3 is a conventional ignition system or an electronic ignition system. The conventional ignition system is mechanical ignition, and the working principle is that a crankshaft drives a distributor shaft to rotate, so that high voltage is generated by switching on and switching off ignition coil contacts, and then the high voltage is transmitted to a spark plug 301 through a corresponding channel to ignite gas in a combustion chamber 211.

As shown in fig. 3, the conventional ignition system includes a spark plug 301 and a micro switch 302, wherein the spark plug 301 is inserted through the stator 1 and an end of the spark plug 301 is inserted into the combustion chamber 211, thereby igniting the fuel in the combustion chamber 211; the microswitch 302 is fixed on the sliding rod 112 and is positioned below the positioning sheet 115, when the end part of the sliding block body 114 is abutted against the bottom of the groove body 21, the positioning sheet 115 moves and abuts against the microswitch 302, and at the moment, the fact that the traditional ignition system can perform ignition operation is shown. As will be readily appreciated, conventional ignition systems include, but are not limited to, the ignition circuit shown in fig. 7.

The electronic ignition system 3 is selected from a non-contact electronic ignition system, a magnetic induction type electronic ignition system, a Hall type electronic ignition system, a computer electronic ignition system with a distributor or a computer electronic ignition system without a distributor.

In the present embodiment, the fuel supply system 4 includes a motor 41, a compressor 42 and a connecting pipe 43 connected in sequence, wherein one end of the motor 41 is connected to the compressor 42, and the other end of the motor 41 is connected to the rotor 2 through a cam mechanism 401; the connection pipe 43 is communicated with a fuel tank 403 through a capillary 402, and the discharge end of the connection pipe 43 is communicated with the combustion chamber 211.

That is, the compressor 42 is driven by the motor 41 to operate to generate high-pressure compressed air, and the compressed air is stored in a compressor container in the compressor 42. The compressor 42 is communicated with the feeding hole through the connection pipe 43, the connection pipe 43 is further connected with the capillary 402, when compressed air flows through the connection part of the connection pipe 43 and the capillary 402, fuel oil in the fuel tank 403 flows into the connection pipe 43 through the capillary 402 based on the bernoulli principle, and the fuel oil is mixed with the compressed air in the connection pipe 43 to form an oil-gas mixture, wherein the oil-gas mixture is the fuel injected into the combustion chamber 211.

Optionally, the stator 1 is provided with a fuel supply pipe 404 inserted into the feed hole, and the connection pipe 43 is communicated with the fuel supply pipe 404.

Further, the structure of the fuel supply system 4 is improved to realize the control of fuel injection, specifically, the fuel supply system 4 further includes a control module 44 electrically connected to the electric motor 41, the control module 44 includes a battery 441, a start button 442 electrically connected to the battery 441, a normally closed switch 443 located below the cam mechanism 401, and a micro valve 444 located on the connection pipe 43, the start button 442 is electrically connected to the electric motor 41, the normally closed switch 443 is electrically connected to the micro valve 444, the rotation of the cam mechanism 401 may cause the normally closed switch 443 to intermittently open, and the micro valve 444 opens when the normally closed switch 443 opens.

The control module 44 is divided into two parts, one of which is a start button 442 for controlling whether the fuel supply system 4 is operated, and when the start button 442 is pressed, the motor 41 is in a start state and the compressor 42 starts to operate. Alternatively, the activation button 442 is configured as a normally open switch.

Secondly, to control the fuel supply system 4 to accurately feed, it is described with reference to the rotation of the rotor 2, that is, in the rotation process of the rotor 2, only when the sliding block 11 is inserted into the groove 21 and separates the combustion chamber 211, the fuel needs to be fed into the combustion chamber 211, and the fuel supply system 4 feeds the fuel periodically, but not all the time.

First, a micro-valve 444 is provided on the connection pipe 43 to close the connection pipe 43, so as to prevent the compressed air from flowing to the rotor 2 through the connection pipe 43 after the motor 41 is started. Then, the opening and closing of the micro valve 444 is controlled by the normally closed switch 443, that is, when the normally closed switch 443 is closed, the micro valve 444 is closed, and when the normally closed switch 443 is opened, the micro valve 444 is also opened. Finally, the cam mechanism 401 connected to the motor 41 controls the opening and closing of the normally closed switch 443, that is, the cam mechanism 401 is provided with a protrusion extending outward, the motor 41 rotates to drive the cam mechanism 401 to rotate, when the protrusion passes through the normally closed switch 443, the sensing portion of the normally closed switch 443 senses a signal of passing of the protrusion in a non-contact manner or a contact manner, each time the normally closed switch 443 senses the signal, that is, opens for a certain period of time, and correspondingly, the micro-valve 444 also opens for a certain period of time, thereby supplying fuel to the tank body 21.

Further, the protrusion is provided corresponding to the groove 21, and the rotation speed of the motor 41 is controlled so that the rotor 2 rotates by a certain angle to replenish the fuel.

In this embodiment, the internal combustion engine further includes a cooling system, the cooling system includes a plurality of air-cooled blades 51 located on the end face of the rotor 2 and a water-cooling cavity located on the stator 1, a cooling liquid is provided in the water-cooling cavity, the water-cooling cavity is connected with the radiator through a water-cooling pipe, and a circulating pump is provided on the water-cooling pipe.

Based on the design, the cooling system is divided into an air cooling part and a liquid cooling part, wherein the air cooling part is a plurality of air cooling blades 51 rotating along with the rotor 2 and mainly used for radiating heat of the rotor 2; the liquid cooling part is a water cooling loop consisting of a water cooling cavity, a water cooling pipe and a radiator, and the circulating pump drives cooling liquid in the water cooling loop to circularly flow, so that the stator 1 mainly radiates heat.

In one possible design, the air-cooled blades 51 are disposed at both ends of the rotor 2, and eight air-cooled blades 51 are provided at each end. The cooling fluid includes, but is not limited to, cooling water and cooling oil.

In the embodiment, the stator 1 is arranged as a cylinder with one closed end and the other open end, and the open end of the cylinder is detachably connected with an end cover 6; therefore, the open end of the cylinder is closed by the end cover 6, so that the safety of the internal combustion engine during working is improved, the stability of the rotation of the rotor 2 is improved, and the stable power output is ensured.

In this embodiment, an output shaft 202 is disposed on the axis of the rotor 2, one end of the output shaft 202 is inserted into the closed end of the cylinder, and the other end of the output shaft 202 passes through the end cover 6. Based on the design, the output shaft 202 stabilizes the assembling relationship between the stator 1 and the rotor 2, ensures that the combustion chamber 211 is always in a closed state, and realizes power output to move the driven machine.

In this embodiment, the slot bodies 21 are provided with a plurality of slots and arranged at intervals along the circumferential direction of the rotor 2, the sliding blocks 11 are provided with a plurality of slots and arranged at intervals along the circumferential direction of the stator 1, and the slot bodies 21 and the sliding blocks 11 are arranged in a one-to-one correspondence; referring to fig. 1, 2 and 6, the groove 21, the sliding block 11, the feeding hole, the exhaust hole and the ignition end of the ignition system 3 are all arranged in a one-to-one correspondence, thereby forming a driving set. Correspondingly, the fuel supply system 4 is provided with a plurality of discharge ends, and the discharge ends and the feed holes are arranged in a one-to-one correspondence manner.

Meanwhile, it is easy to understand that the number of the driving sets, including but not limited to four shown in fig. 1-2, can be adaptively increased or decreased according to actual use conditions.

In a possible implementation, the ignition system 3 causes the driving structure to burn synchronously to do work when the slots 21 are equally spaced on the rotor 2. Based on the design, the air intake-work-exhaust work is synchronously realized among the tank bodies 21, the power output of the internal combustion engine is in a wave line shape, the power output reaches the peak value during the work stroke, the power output gradually decreases from the work stroke to the next circulating air intake stroke, reaches the valley value during the air intake stroke, and periodically and alternately appears along with the rotation of the rotor 2.

In another possible implementation, the ignition system 3 may cause the driving structure to burn in sequence to do work when the slots 21 are distributed on the rotor 2 at unequal intervals. Based on the design, the air intake, the work application and the exhaust work are sequentially completed among the groove bodies 21, so that the power output of the internal combustion engine is stable and strong, and the vibration of a driven machine is reduced.
