Description
Technical Field
[0001] This utility model relates to the field of energy saving in internal combustion engines, specifically an internal combustion engine combustion-supporting device. Background Technology
[0002] The statements in this section are merely background information related to this utility model and do not necessarily constitute prior art.
[0003] Internal combustion engines, as drive components for various power devices, can be applied in multiple equipment fields. They are heat engines that convert the heat energy released from fuel combustion within the machine directly into power. The most common types are diesel and gasoline engines. They convert internal energy into mechanical energy, changing internal energy through work. However, internal combustion engines have a significant problem: the combustion of fuel requires a large amount of oxygen. When the accelerator is pressed to increase power, both fuel injection and oxygen consumption increase simultaneously. However, due to insufficient air intake, black smoke is emitted during exhaust. The carbon monoxide and nitrogen oxides in this smoke cause environmental pollution, and there are also issues with insufficient power and high fuel consumption. Therefore, combustion-assisted devices are needed to improve the fuel efficiency of internal combustion engines, ensuring complete combustion of fuel within the engine.
[0004] Existing internal combustion engine combustion-aiding devices generate ozone to aid combustion. The applicant previously filed an invention patent application (CN2023105614102) entitled "An Energy-Saving System and Method for Internal Combustion Engines Based on Corona Discharge Principle." This application describes generating ozone by ionizing air according to the corona discharge principle. After high-voltage energization, an ozone generator with a pointed tip ionizes the air between itself and the negative electrode connector. Oxygen molecules in the air collide with electrons accelerated by the electric field, dissociating into oxygen atoms. The generated oxygen atoms or ions then collide with oxygen molecules to produce ozone. However, this device has a drawback in practical use: the distance between the ozone generator on the positive electrode connector and the negative electrode connector is fixed. The radius of the negative electrode connector determines the air-breakdown gap. Therefore, when a small amount of dust in the air enters this space, it reduces the gap, leading to short circuits and arcing, thus reducing ozone production. This necessitates the addition of air filters during actual use of the aforementioned devices. Furthermore, in harsh environments, such as the dusty and sandy conditions of Northwest China and on fishing vessels at sea, the equipment is prone to frequent damage and malfunction warnings, impacting the user experience. Moreover, given the demanding operating environment and limited ozone production of these devices, there is still room for improvement in fuel efficiency.
[0005] Existing internal combustion engine combustion assist devices rely on batteries for power. During use, the voltage of a battery changes with the amount of charge. The input voltage of the internal combustion engine combustion assist device is a fluctuating value rather than a constant value. This means that when powered by a battery, the output voltage is affected by the fluctuation of the input voltage, resulting in unstable output voltage and output power. It is impossible to maintain the output power at its maximum value. Therefore, based on the above reasons, further improvements to the product are needed. Utility Model Content

[0010] The high-voltage drive module includes a boost module, a power stabilization module, a TVS module, a temperature sensor connected to the boost module, a fan, and a fault detection module for monitoring the status of the ozone generator.
[0011] One end of the boost module is connected to the connecting plate, and the other end of the boost module is connected to the wire mesh on the outside of each insulating tube. After the boost module inverts and increases the input voltage, it provides the high-voltage power required for the ozone generating unit to generate ozone. The TVS module is used to protect the electronic components in the circuit from being damaged.

[0026] The present invention will be further illustrated below with reference to specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that after reading the teachings of this invention, those skilled in the art can make various alterations or modifications to the present invention, and these equivalent forms also fall within the scope defined in this application.
[0027] The present invention relates to an internal combustion engine combustion-supporting device, the main structure of which includes an ozone generating unit and a high-voltage drive module;
[0028] As shown in the accompanying drawings Figure 3 and Figure 4As shown, the ozone generating unit is connected to the high-voltage drive module. The ozone generating unit includes two connecting plates 1 and multiple ozone generating elements arranged in a staggered manner. Each ozone generating element includes a connecting shaft 2 connected to the connecting plates 1 at both ends, an insulating tube 3 sleeved with the connecting shaft 2, a wire mesh 4 sleeved on the outside of the insulating tube 3, and a rubber pad 5 set between the contact surfaces of the connecting plates 1 and the insulating tube 3.
[0029] The connecting shaft 2 is a threaded rod at both ends and a smooth shaft in the middle. The threaded rods and nuts at both ends are fixed to the connecting plate 1 by threaded connection. The insulating tube 3 is sleeved on the smooth section of the connecting shaft 2. The insulating tube 3 is a quartz tube, which serves as an insulating medium to block the discharge channel that penetrates the air gap.
[0030] The device primarily utilizes dielectric barrier discharge to ionize air and generate ozone. Dielectric barrier discharge is a non-equilibrium gas discharge, also known as dielectric barrier corona discharge or silent discharge, where an insulating dielectric is inserted into the discharge space. During the discharge process between the two electrodes (wire mesh 4 and connecting shaft 2), if there is only air without a dielectric barrier, direct air electrolysis will generate an electric arc, converting electrical energy into light and heat. However, if a dielectric (insulating tube 3) is added between the two electrodes, preventing direct conduction in the air, a discharge corona will be generated on the dielectric surface. High-energy ions in this space on the dielectric surface will decompose oxygen molecules in the air into oxygen atoms, which then recombine to form ozone molecules, significantly improving ozone generation efficiency. This high-voltage driven dielectric barrier discharge is a common application method in ozone generators. The increased frequency of the drive circuit further enhances discharge efficiency and ozone generation efficiency. Compared to products in the background technology, this type of product has a higher efficiency in ionizing air to generate ozone, lower environmental requirements, and stronger adaptability. It is less prone to arcing due to dust, oil, or other impurities in the environment, which could lead to frequent product malfunctions. Compared to the ozone generation efficiency of products in the background technology, this product has a higher ozone generation efficiency. The existing products have a limited number of ozone generating components within the negative electrode generator, and their ozone generation efficiency is affected by the air intake within the negative electrode generator, both of which limit the amount of ozone generated. This product, however, allows for the installation of multiple ozone generating units on a single unit according to usage requirements. Each ozone generating unit ionizes the air surrounding the mesh 4, thus reducing limitations and allowing the number of ozone generating units to be increased or decreased based on the user's needs. Because the ozone generator requires air ionization to produce ozone, multiple ozone generators need to be staggered and spaced appropriately to maximize ionization efficiency.
[0031] Because the connecting shaft 2 is threaded, its diameter during machining is not an integer but needs to match the diameter of the thread. This results in an error between the outer diameter of the connecting shaft 2 and the inner diameter of the quartz tube, preventing a precise fit. Consequently, the gap between the connecting shaft 2 and the wire mesh 4 on the outside of the blocking medium becomes uneven, leading to uneven electric field strength between them and affecting ozone generation efficiency. To address this issue, a layer of tin foil is added between the connecting shaft 2 and the insulating tube 3. During production, the tin foil is cut to its specifications and rolled onto the connecting shaft 2. This tin foil layer increases the diameter of the connecting shaft 2, ensuring a proper fit between its outer diameter and the inner diameter of the insulating tube 3. This results in a more uniform gap between the connecting shaft 2 and the wire mesh 4, creating a denser and more uniform electric field, leading to higher air ionization efficiency and increased ozone generation. It also prevents collisions between the insulating tube 3 and the connecting shaft 2 when the equipment is subjected to vibration, thus preventing the insulating tube 3 from breaking or cracking. For the insulating tube 3, burrs will appear at both ends during processing and cutting. After the high voltage power is applied and it comes into contact with the connecting plate 1, arcing will occur. Furthermore, when the insulating tube 3 breaks and cracks, the connecting shaft 2 and the outer wire mesh 4 will short-circuit, which will also cause arcing. In order to limit and buffer the insulating tube 3 and separate the two ends of the insulating tube 3 from the connecting plate 1, a rubber pad 5 is provided between the contact surface of the connecting plate 1 and the insulating tube 3.
[0032] The ozone generating unit requires high voltage to ionize air and produce ozone, so a high-voltage drive module is needed to increase the voltage. The high-voltage drive module includes a boost module 6, a power stabilization module, a TVS module, a temperature sensor connected to the boost module 6, a fan, and a fault detection module for monitoring the status of the ozone generator. The fan blows the generated ozone out from near the ozone generator, and then another exhaust fan blows the ozone into the intake manifold of the internal combustion engine to aid combustion and accelerate gas exchange to provide fresh air.
[0033] One end of the boost module 6 is connected to the connecting plate 1, and the other end is connected to the wire mesh 4 on the outside of each insulating tube 3. The boost module 6 is a high-voltage transformer that inverts and increases the input battery voltage from 22V-32V to 5-6kV, and then outputs the increased voltage to the ozone generating unit to provide it with the high-voltage power required to generate ozone. For some large internal combustion engine equipment that requires higher ozone levels for combustion, the device will have multiple ozone generating units, each of which requires a separate boost module 6. Therefore, the number of boost modules 6 must be matched with the number of ozone generating units. Since the boost modules 6 generate heat during long-term operation, each boost module 6 is equipped with a temperature sensor to prevent overheating from damaging other electronic components.
[0034] The main purpose of the fault detection module is to monitor the condition of the insulating components. When the insulating components are subjected to equipment vibration and impact, they may break or crack, which can lead to arcing. Arcing can easily cause fires. Therefore, the feedback circuit of the fault detection is used to monitor the condition in real time.
[0035] Since the device is powered by the battery of an internal combustion engine, the voltage of the battery changes with the amount of charge during use. Therefore, the input voltage mentioned above is a fluctuating value rather than a constant value. This causes the output voltage of the device to be affected by the fluctuation of the input voltage when powered by the battery, resulting in unstable output voltage and output power, which in turn affects the ozone generation efficiency. Therefore, further improvements are needed:
[0036] The circuit includes a TVS module and a power stabilization module. The TVS module is a transient voltage suppressor diode. When the TVS diode is subjected to a high-energy transient surge, it can rapidly reduce its impedance and absorb a large current, clamping the voltage across its terminals to a predetermined value. This ensures that downstream circuit components are protected from damage caused by the transient high-energy surge, thus protecting other electronic components in the circuit. The power stabilization module is a DC-DC converter. The working principle of a DC-DC converter mainly relies on switching power supply technology. It utilizes switching devices such as MOSFETs or transistors, and by periodically controlling the switching of these devices, it achieves pulse modulation of the input voltage, thereby realizing voltage conversion and automatic voltage regulation. Specifically, the DC-DC converter stores the input electrical energy in a capacitor or inductor through high-frequency switching. When the high-frequency switch is open, the stored electrical energy is output to provide a preset voltage and current, ensuring that the input voltage remains constant and is not affected by the battery charge, always maintaining maximum output power.
[0037] The ozone generating unit and high-voltage drive module are housed inside the casing 7. The casing 7 has an air inlet 8 and an air outlet 9. Air is filtered through the air inlet 8 before entering the casing 7. An air filter is installed in the air inlet 8, and an exhaust fan is installed in the air outlet 9. The air filter is multi-stage, effectively filtering out dust and impurities from the air. The fan blows the generated ozone from near the ozone generator and then through the exhaust fan to the intake manifold of the internal combustion engine, aiding combustion. Since the exhaust fan blows ozone into the engine's intake manifold, a malfunction would reduce its combustion efficiency. Therefore, the exhaust fan has a feedback unit to monitor its speed and operating status in real time. In dusty environments, the air filter is prone to clogging, which reduces the exhaust fan speed. Therefore, the exhaust fan speed can be used to indirectly assess the air filter's condition and determine if replacement is necessary.
[0038] In summary, this device is used in internal combustion machinery to provide combustion assistance to the engine, thereby achieving fuel savings. This application offers higher and more consistent ozone generation efficiency, unaffected by changes in input voltage. It can adapt to harsh environments, unaffected by dust and oil contamination, and the device allows for the selection of ozone generation levels tailored to the specific needs of the equipment being used.
