The invention relates to an energy-saving system of an internal combustion engine and a method thereof based on a corona discharge principle, wherein the energy-saving system of the internal combustion engine is described, and the main body structure comprises a circuit control system connected with an internal combustion mechanical power supply and an ozone generating device arranged in an air inlet pipeline of the internal combustion engine;
the invention relates to an energy-saving system of an internal combustion engine and a method thereof based on a corona discharge principle, firstly describing the energy-saving system of the internal combustion engine, wherein the main body structure comprises a circuit control system 8 connected with an internal combustion mechanical power supply and an ozone generating device 2 arranged in an air inlet pipeline 1 of the internal combustion engine;
first, the positions of the circuit control system 8 and the ozone generating device 2 are described, as shown in fig. 1 of the specification, the air filter element is provided in the air intake pipe 1 of the internal combustion engine, the ozone generating device 2 is connected with the circuit control system 8, then the ozone generating device 2 is placed in the air intake pipe 1, the circuit control system 8 is arranged outside the air intake pipe 1, the ozone generating device 2 in the air intake pipe 1 generates ozone, and the oxidizing property of the ozone is high, so that the combustion-supporting effect on the combustion of the internal combustion engine is achieved.
In the conventional ozone generating device 2, although the air entering the internal combustion engine can be ionized to generate ozone, the efficiency of generating ozone when the air is ionized plays a critical role in the performance of the device, and the following is a specific structure of the ozone generating device 2:
as shown in fig. 2-5 of the drawings, the ozone generating device 2 comprises a negative electrode connecting piece 3, insulating pieces 4 arranged at two ends of the negative electrode connecting piece 3, a positive electrode connecting piece 5 arranged inside the negative electrode connecting piece 3, and a plurality of ozone generating sheets 6 arranged on the positive electrode connecting piece 5 at equal intervals;
the positive electrode and the negative electrode of the internal combustion mechanical power supply are connected with a circuit control system 8, and the circuit control system 8 is connected with the positive electrode connecting piece 3 and the negative electrode connecting piece 3 of the ozone generating device 2. The negative electrode connecting piece 3 is cylindrical, and the negative electrode connecting piece 3 is provided with a limit bolt 14, and the limit bolt 14 is used for limiting a connecting terminal of a circuit negative electrode of the circuit control system 8. The both ends cooperation of negative pole connecting piece 3 is equipped with insulating piece 4, and insulating piece 4 centre of a circle position department is equipped with the connecting hole, and positive pole connecting piece 5 cup joints in the connecting hole of insulating piece 4, and positive pole connecting piece 5 is spacing at negative pole connecting piece 3 both ends with two insulating pieces 4. The insulator 4 is used for separating the positive electrode connecting piece 5 from the negative electrode connecting piece 3, and a short circuit phenomenon can occur after the positive electrode connecting piece 5 contacts with the negative electrode connecting piece 3, so that the ozone generating device 2 cannot ionize air. As shown in fig. 3 of the drawings, the positive electrode connection member 5 comprises a connection post 10, a plurality of isolation rings 11 arranged on the connection post 10 at equal intervals, and an ozone generating sheet 6 arranged on one side of each isolation ring 11;
the connecting column 10 is connected with the positive pole of the high-voltage driving circuit of the circuit control system 8, the tail end of the connecting column 10 is in threaded connection with a limiting piece 12, the limiting piece 12 is a nut, the connecting column 10 limits the insulating piece 4 on the negative pole connecting piece 3 through a thread diagram which is not shown, and meanwhile, the insulating piece 4 separates the positive pole connecting piece 5 from the negative pole connecting piece 3. The positive pole of the circuit control system 8 is connected with the connecting column 10.
The core component of the ozone generating device 2, the ozone generating sheet 6, ionizes air according to the corona discharge principle, and the chemical reaction equation is: 3O (3) 2 ＝＝2O 3 The reaction condition is ionization, for most of the ozone generating sheets 6 of the existing ozone generating device 2, for the ionized air of the circular ozone generating sheets 6, when the circular ozone generating sheets 6 (without tips) have the same field intensity after the ozone generating sheets 6 are electrified, the ozone generating efficiency of the circular ozone generating sheets 6 is low, and the ionization voltage and the energy consumption are high when the circular ozone generating sheets 6 are ionized; patent No. zl202121514761.0 relates to a brush-type ozone generating sheet 6 for ionizing air, which generates a strong electric field at the tips of the brushes after the ozone generating device 2 is electrified, so that ozone is generated, but in the case of the brush-type ozone generating sheet 6, because the body of the ozone generating sheet 6 is a brush (copper bar), ionization occurs near the tips of the brushes after the strong electric field is generated at the tips of the brushes, but the mutual intersection among the brushes after the electrification and too small gaps among a plurality of brushes result in low efficiency of ionized air, and if the device needs to adjust voltage, the voltage adjusting range is small, and in the case of special weather, the short circuit occurs due to the fact that the air gaps are easily broken down.
For the ozone generating sheet 6 of the device, as shown in figure 4 of the specification, the cross section of the ozone generating sheet 6 is parallel to the cross section of the negative electrode connecting piece 3, a plurality of discharging sharp teeth 7 are arranged on the circumference array of the ozone generating sheet 6, the discharging sharp teeth 7 are uniformly distributed on the circumference of the ozone generating sheet 6, the field intensity of the ozone generating sheet 6 is uniformly distributed after the power is applied, the circle center of the ozone generating sheet 6 gradually increases gradually towards the tooth tips of the discharging sharp teeth 7, and the tooth surfaces of the discharging sharp teeth 7 gradually increase towards the edges of the discharging sharp teeth 7. After the ozone generating device 2 is electrified with high voltage, the electrification amount of the ozone generating sheet 6 and the connecting column 10 is increased, the tooth tip of the discharge sharp teeth 7 and the edge of the discharge sharp teeth 7 are pointed relative to the tooth surface of the discharge sharp teeth 7, the larger the curvature is, the higher the surface charge density is, the nearby field intensity is higher than the tooth surface field intensity of the discharge sharp teeth 7, and the discharge sharp teeth 7 have the largest curvature, so that the air around the tooth tip of the discharge sharp teeth 7 and the edge of the discharge sharp teeth 7 can be ionized after the high voltage is electrified, weak fluorescence and fizziness are accompanied, oxygen molecules in the air are dissociated into oxygen atoms after being excited by collision with electrons accelerated by an electric field when the air is ionized, and the generated oxygen atoms or ions collide with the oxygen molecules to generate ozone. The principle of the tip discharge is that the air entering the air inlet pipeline 1 is ionized along the tooth tips of the discharge sharp teeth 7 and the edge periphery of the discharge sharp teeth 7 to produce ozone, compared with the circular or brush-type ozone generating sheet 6, the ionization sharp points of the discharge sharp teeth 7 are more than the two under the same voltage or electric field intensity, and the ionization sharp points are more, so that the efficiency is higher when ozone is produced by ionization.
However, for the ozone generation amount, the factors determining the ozone generation are the electric field intensity (voltage between the positive electrode and the negative electrode of the ozone generating device 2) and the distance between the discharge sharp teeth 7 of the ozone generating device 2 and the inner surface of the negative electrode connecting piece 3, so that when the ozone generating device 2 is suitable for different vehicle types, the ozone generating device needs to be designed according to the diameters of the air inlet pipelines 1 of different vehicle types, and meanwhile, the required ozone generation amount needs to be set, so that the ozone generating device is suitable for different types of diesel locomotives, and the numerical relation between the distance between the discharge sharp teeth 7 and the inner surface of the negative electrode connecting piece 3 and the voltage at two ends of the ozone generating device 2 needs to be controlled, and the estimation process is as follows:
before estimation, it should be clear that when the voltage between the positive electrode and the negative electrode of the ozone generating device 2 is too high, the air between the ozone generating sheet 6 on the positive electrode connecting piece 5 and the negative electrode connecting piece 3 breaks down, the air becomes a conductor, the short circuit of the ozone generating device 2 is caused, the phenomenon of electric arc occurs, the ionization energy of the ozone generating device 2 is converted into the electric arc after the electric arc occurs, and the ionization energy is greatly consumed, so that the air cannot be ionized to generate ozone, therefore, the voltage between the positive electrode and the negative electrode of the ozone generating device 2 and the interval between the negative electrode connecting piece 3 and the ozone generating sheet 6 must be considered when the ozone generating device 2 is designed.
Therefore, the pipe diameter of the negative electrode connecting piece 3 of the ozone generating device 2 can be set according to the pipe diameters of different internal combustion machinery air inlet pipelines 1, the gap distance of breakdown air is established by the radius of the negative electrode connecting piece 3, as shown in figure 4 of the specification, the gap distance of the breakdown air = the radius of the negative electrode connecting piece 3-the radius of the discharge sharp teeth 7, the breakdown voltage of the air gap cannot be accurately calculated due to imperfect gas discharge theory, and the breakdown voltage is related to air pressure and humidity, so that in the design, the breakdown voltage can only be gradually measured by a test method, and whether the air is broken down or not is judged by observing whether the pressurized ozone generating device 2 generates an arc or not, as shown in figure 6 of the specification, the distance air is measured by test data: the gap distance of the breakdown air is in a linear relation with the breakdown voltage, and the gap distance is in direct proportion to the breakdown voltage, namely the breakdown voltage is higher as the gap distance is larger, but for the radius selection of the discharging sharp teeth 7, the ozone generation efficiency is also needed to be considered, the gap distance data of the ozone generation efficiency and the breakdown air are shown as a graph of the gap distance data of the ozone generation efficiency and the breakdown air in the specification, as shown in figure 7 of the accompanying drawings, the AB section is a linear function, and the AB section gradually decreases along with the breakdown gap 13, and the ozone generation amount also gradually increases; the BC segment is a curve function, the BC segment is further reduced along with the penetration gap, and the ozone generation amount is increased to a peak value; the CD segment decreases with decreasing breakdown gap 13 while ozone generation begins to decrease gradually; the ozone generation amount is continuously reduced and is stabilized after the DE section breakdown gap 13 is gradually changed to a minimum value. From the above image, it is found that the BC segment function image has the highest ozone generation amount and the peak occurs in BC segment, so that when the radius of the discharge tooth 7 is selected, the selection is performed in BC segment.
The CD segment part starts to decrease in ozone generation amount in the whole function image, mainly because: because the ozone generating sheet 6 generates ozone by ionizing air at high pressure and the ozone generating sheet 6 generates high heat, the generated ozone is decomposed by the high heat, so that when the breakdown gap 13 is selected, the situation needs to be avoided, and after the proper breakdown gap 13 is selected, the air flows through the breakdown gap 13 and the discharge sharp teeth 7 of the ozone generating sheet 6 when the air inlet pipeline 1 of the internal combustion engine is in air inlet, and the flow speed and the pressure at the edges and corners of the discharge sharp teeth 7 are small, so that the generated heat is released timely, and the internal structure of the ozone generating device is different from the existing ozone generating device 2 in complex structure and the unique heat dissipation mechanism is needed for heat dissipation.
For the field of gas discharge, the electric field has a uniform electric field, a slightly nonuniform electric field and a very nonuniform electric field, and for the electric field determination of various structures, the determination is made by the electric field non-uniformity coefficient, the electric field non-uniformity coefficient=maximum electric field intensity/average electric field intensity, the electric field non-uniformity coefficient=1 is a uniform electric field, the electric field non-uniformity coefficient<2 is a slightly non-uniform electric field, and the non-uniform coefficient of the electric field>4 is a very uneven electric field, corona discharge mostly occurs in the very uneven electric field, so that in order to further rapidly establish the numerical relation between breakdown voltage and discharge gap under different pipe diameters, the uneven electric field coefficient of the electric field is introduced to perform a calculation approximate formula, after the radius of the cathode connector 3 and the ozone generating sheet 6 is selected, the field intensity of the cathode connector 3 and the ozone generating sheet 6 is required to be measured, assuming that the breakdown voltage is 14kv, the breakdown gap 13 is 1.6cm, the radius r of the cathode connector 3 is 2.5cm, the maximum electric field intensity of the discharge sharp teeth 7 is 35kv/cm according to the measurement, the average electric field intensity is 8kv/cm, and the calculation is performed through a plurality of groups of data, so that the estimated formula of the breakdown voltage is U=E max * d/f, wherein U is breakdown voltage, E max For maximum electric field strength, d is the distance of the breakdown gap 13, and f is the electric field non-uniformity coefficient = maximum electric field strength/average electric field strength. The maximum electric field intensity and the electric field non-uniformity coefficient of the formula are both regarded as a quantitative ratio, because the breakdown voltage and the breakdown gap 13 are changed in a positive proportion, the breakdown voltage and the breakdown gap 13 are only changed when different pipe diameters are applied, but the ratio can be regarded as a quantitative ratio, so that the maximum electric field intensity and the average electric field intensity of the discharging sharp teeth 7 can be obtained in the specific test or calculation process, and the electric field intensity can be obtainedThe non-uniformity factor f can thus be given as a relation between the breakdown voltage and the distance of the breakdown gap 13. For the breakdown gaps 13 with different pipe diameters, the function image can be calculated according to the graph shown in fig. 7 of the specification, and the ratio of the distance of the breakdown gap 13 to the radius of the negative electrode connecting piece 3 is 0.55-0.65, so that the optimal distance of the breakdown gap 13 and the corresponding breakdown voltage value can be obtained. Or the optimal breakdown distance is measured by a test method, and the corresponding breakdown voltage value is calculated by the formula.
The above-mentioned calculation of the breakdown voltage and the breakdown gap 13 will be described below in conjunction with the voltage adjustment of the ozone generating device 2 by the circuit control system 8, which is only the most important factor affecting the ozone generating device 2, and in addition, an influence factor must be considered, namely, the distance between two adjacent ozone generating sheets 6, i.e. the thickness of the isolating ring 11. Regarding the thickness of the spacer ring 11, the number of ozone generating sheets 6 inside one ozone generator is determined, the number of ozone generating sheets 6 is correlated with the ozone generating concentration, since each ozone generating sheet 6 ionizes air flowing through the ozone generating sheet 6 at the time of ionization, it is necessary to achieve the ionization efficiency maximization in the negative electrode connection member 3 of a specific length, ionization (generation) efficiency=total amount of ozone generation/intake air amount, which is controlled under test conditions and measured (no measurement during actual use), for which the ionization efficiency is maximized at the inflection point in the figure as shown in fig. 8 of the specification by test data, and the spacer ring 11 thickness is 5mm, and the number of ozone generating sheets 6 is 12, so that at the spacer ring 11 thickness of 5mm, the ionization efficiency is maximized, and the spacer ring 11 thickness can be ionized with a higher efficiency in the range of 3mm to 8 mm. As shown in fig. 5 of the accompanying drawings, because the number of the ozone generating sheets 6 plus the thickness of the isolating ring 11 cannot be exactly adapted to the length of the negative electrode connecting piece 3, and the ozone generating sheets 6 cannot be in contact with the insulating piece 4, a cushion block 9 needs to be arranged at the extreme end to control the distance between the extreme end ozone generating sheets 6 and the insulating piece 4, so that the ozone generating device 2 cannot rotate when in use, and the ozone generating efficiency is affected.
For the device to dissipate heat, as shown in fig. 1 of the specification, the ozone generating device 2 and the air inlet pipeline 1 of the internal combustion engine are concentrically arranged, when external air enters the air inlet pipeline 1 through the air filter element, heat generated during ionization of the ozone generating device 2 flows along with continuous flow of the external air, ozone generated simultaneously by the air is gradually taken away and also enters the internal combustion engine, the ozone generating device 2 is simple in structure, the internal structure does not obstruct the flow of the external air, and sufficient gaps exist to enable the external air to flow through the internal of the ozone generating device, so that the external air can dissipate heat only by virtue of natural flow of the air.
For the relation between the distance between the electric tines and the inner surface of the negative electrode connecting piece and the relation between the voltage values at the two ends of the ozone generating device and the relation between the breakdown gap distances of different pipe diameters and the radius ratio of the negative electrode connecting piece are established, a critical factor still exists for the relation, namely the number of ozone generating sheets, the influence of the number of discharge tooth tips on the ozone generating amount is gradually measured through an experimental method in the initial stage of product development, as shown in figure 10 of the specification, the ozone generating amount is at a higher level in the interval of 25-40 discharge tooth numbers, wherein the ozone generating efficiency is highest when the discharge tooth number is 35. The function image change process in the drawing can be interpreted as an ascending phase when the number of discharge tines is 10-30, because the ionization process of the ozone generating sheet mainly occurs at the tips and edges of the discharge tines, the ascending phase can be approximately regarded as the more the number of discharge tines is, the more the ozone generation amount is, the slightly descending phase when the number of discharge tines becomes 30-45, the ionization efficiency of the number of discharge tines on the ozone generating sheet reaches saturation, so the ozone generation amount slightly decreases, and when the number of discharge tines exceeds 45, the saturation interval has been exceeded, so the ozone generation amount further decreases.
Circuit control system 8:
the above is the principle and the estimation process of the ozone generating device 2, and the circuit control system 8 and how to control the ozone generating device 2 to correspondingly control the ozone generating amount under different accelerator forces are described below. As shown in fig. 1 of the drawings, a circuit control system 8 is integrally arranged in a shell, and is tied on the outer wall of an air inlet pipeline 1 of the internal combustion engine by using a strapping tape or a strap, and the circuit control system 8 comprises a high-voltage driving circuit, a control circuit and a fuse which are electrically connected with an ozone generating device 2;
the circuit diagram of the circuit control system 8 is shown in fig. 9 of the specification, and the control circuit comprises a wind pressure detection source, a variable frequency controller and a power supply control component, because the fuel injection quantity inside the internal combustion engine is different under different throttle forces, when the fuel injection quantity is large, a large amount of oxygen is consumed during fuel combustion, and external air enters the internal combustion engine from the air inlet pipeline 1 of the internal combustion engine, so that the throttle force of the internal combustion engine during driving can be judged by detecting the air quantity in the air inlet pipeline 1 of the internal combustion engine through the wind pressure detection source. The variable frequency controller converts data according to the data information of the wind pressure detection source to output signals, and the variable frequency controller adjusts the output voltage of the high-voltage driving circuit in a proportion interval of the voltage of the ozone generating device 2 according to the wind pressure detection source to detect the wind quantity.
The maximum value of the voltage proportion interval of the ozone generating device 2 is equal to 90% -95% of breakdown air voltage, and the minimum value of the voltage proportion interval of the ozone generating device 2 is equal to 75% -80% of penetration air voltage. For the maximum value selection of the breakdown air voltage in the proportion interval, the value of 95% -99% of the breakdown air voltage is not selected, mainly, the weather factor and the air flow rate factor are considered, because the breakdown voltage can be reduced under the conditions of high air humidity and high air flow rate, and in order to avoid the short circuit problem, the breakdown voltage change space under special conditions needs to be reserved, so that the value range of 90% -95% of the breakdown air voltage is selected as the maximum value. For the minimum value of the voltage proportion interval of the ozone generating device 2, the voltage which is just started to generate ozone, namely the corona onset voltage is originally selected, but later, when the voltage which is just started to generate ozone is selected according to actual test, the requirement of a low gear cannot be met, and when the voltage value of each gear is changed excessively during actual adjustment, the internal combustion machinery can generate a sense of abruptness during driving, so that the voltage interval is selected after improvement. For the whole voltage proportion interval of the ozone generating device 2, the voltage value corresponding to each gear can be set evenly according to the gear of the accelerator, and the voltage change value between each gear difference is stable. Each voltage value gear corresponds to proper ozone output and can correspond to the oil injection quantity of the internal combustion engine, so that the ozone generating device 2 has the effect of energy conservation as a whole, and the situations of energy waste or insufficient combustion-supporting effect are avoided.
Because the control process needs to be converted and calculated, a CPU component and a can signal transmission circuit are arranged in the variable frequency controller and used for transmitting and detecting the output voltage value of a power supply control component, and the power supply control component comprises a frequency modulation module, a voltage stabilizing control module and a fault detection module;
and a can signal transmission circuit is also arranged in the power supply control component, and the voltage output value of the high-voltage driving circuit is controlled by the control circuit after receiving the control signal. The frequency modulation module is used for adjusting and controlling the output value of the voltage of the high-voltage driving circuit of the power supply control component. For the voltage stabilizing circuit, the situation that the accelerator is stepped on suddenly can occur when the accelerator is stepped on, the voltage of the ozone generating device 2 is suddenly increased, and the situation that the voltage is unstable is avoided, so the voltage stabilizing control module is used for carrying out time delay control on the value of the target voltage output by the high-voltage driving circuit, the time delay control time is short, and the phenomenon that the voltage rising rate exceeds a proportional interval too fast to cause short circuit is avoided. The fault detection module is used for detecting whether a short circuit occurs between the power supply control assembly and the ozone generating device 2, because in the actual use process, the air inlet pipeline 1 of the internal combustion engine can not be filtered by the air filter element to enter a very small amount of dust, and the dust is equivalent to grounding and reducing discharge gaps after passing through the ozone generating device 2, so that the short circuit and the electric arc occur, the ozone yield is reduced, but the ozone returns to be normal after a short time, and the situation is not in the range of the fault detection module. With the increase of the service time, the air filter or the ozone generating device 2 is in failure once and has continuous short circuit, at the moment, the ozone generating device 2 alarms, the whole system is started once, and if continuous failure alarms, the system needs to be stopped and an overhaul prompt is sent.
Since the circuit control system 8 is liable to cause a short circuit, a fuse box is provided to protect the circuit in order to avoid a circuit failure. For some large heavy internal combustion machines with high oil consumption, the single ozone generating device 2 cannot meet the combustion supporting effect, and a plurality of ozone generating devices 2 can be arranged in parallel in the air inlet pipeline 1, because parallel voltages are equal, and the circuit control system 8 is easy to control.
The control process is as follows: the wind pressure detection source monitors the wind quantity of the air inlet pipeline 1 of the internal combustion engine in real time, the wind quantity is transmitted to the CPU of the variable frequency controller in real time for numerical analysis, the wind quantity is converted into the throttle force of the current internal combustion engine according to the wind quantity, the voltage value output by the power control component is generated through the feedback of the throttle force, and the power control component outputs the corresponding voltage value according to the data information of variable frequency control, so that the voltage of the ozone generating device 2 is changed, and the ozone generating quantity is increased.
In summary, the device converts the air intake amount of the internal combustion machine into the throttle force of the current internal combustion machine, and generates the corresponding voltage value through the feedback of the throttle force to the power control assembly, so that the combustion is carried out according to the amount of ozone required by the combustion of the internal combustion machine, the condition of energy waste or insufficient combustion effect is avoided, the whole energy consumption of the ozone generating device 2 is reduced, the combustion effect can be achieved for driving the internal combustion machine, the condition of black smoke when the internal combustion machine burns insufficiently is avoided, and the exhaust emission is further reduced. And through theoretical calculation and calculation, when designing the ozone generating device 2, the ionization of the ozone generating sheet 6 is more efficient, and the ozone generating amount is higher. Through the formula and the numerical value of the calculation, the voltage interval of the ozone generating device 2 with the optimal efficiency and the numerical relation of main components of the ozone generating device 2 can be quickly matched, so that the ozone generating device can be quickly adapted when different types of internal combustion machines are designed.
