背景技术 Background technique

国际石油价格上涨，必然引出一系列关于车与燃油之间的话题，而柴油车在中国难以进入大城市，便是其中最让人难以解决的事情之一；此问题的背景是：全球石油资源日趋短缺，而汽车消费不断攀升，在找到终极替代能源之前，全世界汽车厂家、能源公司以及政府都在探索延缓石油危机爆发的中间路线：柴油发动机以二氧化碳排放比汽油发动机减少 30%〜45%, 其他有害气体排放方面，柴油发动机也具备明显的优势，特别是欧洲日益严酷的二氧化碳排放问题，柴油发动机比汽油发动机减少近 45%的二氧化碳排放，这是非常可观的数据，并且节能 25%〜30%，成为各个厂家研发和推崇的目标；而且，由于柴油发动机具有低速高扭矩，在 0〜100Km/h的速度范围内加速性能优越，正适合交通拥堵的大城市使用。 The rise in international oil prices will inevitably lead to a series of topics about car and fuel, and it is one of the most difficult things to solve in diesel cars in China. The background of this issue is: Global Petroleum Resources There is a growing shortage, and car consumption continues to climb. Before finding the ultimate alternative energy source, car manufacturers, energy companies and governments around the world are exploring the middle route to delay the oil crisis: diesel engines reduce carbon dioxide emissions by 30% to 45% compared to gasoline engines. Diesel engines also have obvious advantages in terms of other harmful gas emissions. Especially in Europe, the increasingly severe carbon dioxide emissions problem, diesel engines reduce carbon dioxide emissions by nearly 45% compared with gasoline engines. This is very impressive data, and energy saving is 25%~ 30%, has become the target of research and development and respect of various manufacturers; Moreover, because diesel engine has low speed and high torque, it has excellent acceleration performance in the speed range of 0~100Km/h, and is suitable for large cities with traffic congestion.

2010年底的数据显示，中国机动车保有量大概至少在 5800万辆，并以每年大约 1500万辆的速度递增。车用燃油消耗保守估计在 13050万吨，占全年中国石油消耗总量的 1/2，若中国机动车有 20%使用柴油发动机，则少用燃油 2350万吨，交通资金消耗就可以节省约 706 亿元人民币，减少对进口石油的依赖，为世界范围节能减排做出贡献。 According to data at the end of 2010, China's motor vehicle ownership is at least 58 million, and it is increasing at a rate of about 15 million vehicles per year. The fuel consumption of vehicles is conservatively estimated at 130.5 million tons, accounting for 1/2 of China's total oil consumption in the whole year. If 20% of Chinese motor vehicles use diesel engines, they will use 23.5 million tons of fuel, saving transportation capital. RMB 70.6 billion, reducing dependence on imported oil and contributing to energy conservation and emission reduction worldwide.

柴油机代替汽油机可以节约能源 25%〜30%, 中国一年可以节约几百亿甚至上千亿人民币资金，这样有目共睹的好事，为什么柴油发动机没有快速发展起来呢？是什么制约了柴油发动机应用呢？柴油机被认为是城市大气微粒的主要污染源之一，柴油机颗粒物组成复杂并且颗粒粒径甚小，大都属于亚微米级粒子和纳米级粒子，排放后能长时间悬浮于大气中，人们呼吸这种悬浮物到体内对人危害极大；柴油机排出的微粒浓度高于汽油机数十倍；细小的微粒悬浮在大气中，降低了大气的能见度，如被人体吸入可引起呼吸***疾病，甚至致癌；使用柴油机比例的增加，可导致严重的环境污染；控制生成排放有害气体的燃烧过程，是达到净化排放的理想途径。 Diesel engines can save energy by 25%~30% instead of gasoline engines. China can save tens of billions or even hundreds of billions of yuan a year. It is a good thing to see why diesel engines are not developing rapidly. What restricts the application of diesel engines? Diesel engine is considered to be one of the main sources of pollution of urban atmospheric particulates. The composition of diesel particulates is complex and the particle size is very small. Most of them belong to sub-micron particles and nano-sized particles. After being discharged, they can be suspended in the atmosphere for a long time. People breathe this suspension. The damage to the human body is extremely harmful to the human body; the concentration of particulates emitted by the diesel engine is several times higher than that of the gasoline engine; the fine particles are suspended in the atmosphere, reducing the visibility of the atmosphere, such as being inhaled by the human body, causing respiratory diseases, and even causing cancer; using diesel engines The increase in proportion can lead to serious environmental pollution; controlling the combustion process that generates harmful gases is an ideal way to purify emissions.

柴油机尾气中，碳烟颗粒物的质量含量、可溶性有机组分在颗粒物中的质量分数和可溶性有机组分的化学组成。实验得出柴油机犀气中，碳烟颗粒物的含量： 32.6~143.6mg/m³。可溶性有机组分在颗粒物中的质量分数为 18.5%~89.4%。分析柴油发动机产生碳烟颗粒物的原因：一、是缺氧条件下燃烧，这个问题由现代科技研发的 τρι发动机，喷油量控制十分精确，The diesel engine exhaust, the mass content of soot particles, the mass fraction of soluble organic components in the particles, and the chemical composition of the soluble organic components. The experiment found that the content of soot particles in the diesel engine rhythm: 32.6~143.6mg/m ³ . The mass fraction of soluble organic components in the particles is 18.5% to 89.4%. Analysis of the causes of soot particles produced by diesel engines: First, it is burning under anoxic conditions. This problem is controlled by modern technology. The fuel injection quantity is very precise.

TDI采用的喷油器是靠电磁阀控制的，喷油正时和喷油量，都可以由电磁阀根据 ECU发出的指令来精确控制，这就好比汽油发动机的电喷技术一般。不仅如此， TDI发动机还可以实现柴油发动机的闭环控制，这在传统的柴油发动机是没有的，氧传感器等传感部件将尾气情况反馈给 ECU,从而可以根据尾气判断燃烧状况，进而进一步调整供油量，实现富氧条件燃烧; 二、是虽然在富氧条件下，但是由于发动机缸壁、活塞始终处于循环冷却状态，发动机工作喷油时，油雾喷到活塞、汽缸表面时，活塞、汽缸表面温度低于柴油、碳颗粒的起燃点，即低于碳颗粒的氧化反应阈值，碳颗粒起燃点： 550摄氏度。因此，油雾分解出的碳颗粒碰撞到活塞表面、缸体表面时温度达不到碳的氧化反应温度，碳颗粒不能被氧 t：。这种情况尤其在发动机冷机启动时更为明显。 The fuel injector used by TDI is controlled by a solenoid valve. The injection timing and fuel injection amount can be precisely controlled by the solenoid valve according to the command issued by the ECU. This is like the electrospray technology of a gasoline engine. Not only that, but the TDI engine can also be realized. The closed-loop control of the diesel engine, which is not available in the conventional diesel engine, the sensing component such as the oxygen sensor feeds back the exhaust situation to the ECU, so that the combustion condition can be judged according to the exhaust gas, thereby further adjusting the fuel supply amount to achieve the oxygen-rich condition combustion; Second, although in the oxygen-rich condition, the engine cylinder wall and the piston are always in the circulating cooling state. When the engine is working on the fuel, when the oil mist is sprayed on the piston and the cylinder surface, the piston and cylinder surface temperature is lower than the diesel and carbon particles. The ignition point is lower than the oxidation threshold of the carbon particles, and the ignition point of the carbon particles is 550 degrees Celsius. Therefore, when the carbon particles decomposed by the oil mist collide with the surface of the piston and the surface of the cylinder, the temperature does not reach the oxidation reaction temperature of carbon, and the carbon particles cannot be oxygenated by t:. This is especially the case when the engine is cold.

为解决碳颗粒排放问题，欧洲强制说采取排气***碳颗粒过滤，柴油车型都己配备碳颗粒回收装置，及游离碳二次点火催化燃烧，以减少碳颗粒排放；中国工程界对柴油发动机尾气净化采用机械过滤、催化反应和静电分离技术对尾气进行净化处理。主要特征是三元催化反书 In order to solve the problem of carbon particle emissions, Europe has forced the use of exhaust system carbon particle filtration, diesel vehicles have been equipped with carbon particle recovery devices, and free carbon secondary ignition catalytic combustion to reduce carbon particle emissions; China's engineering industry for diesel engine exhaust The purification uses mechanical filtration, catalytic reaction and electrostatic separation technology to purify the exhaust gas. The main feature is the three-way catalytic book

应器做成层板式结构，陶瓷过滤体由内外两层杯状套卷成，电加热器是温度自动补偿以达到碳氧化温度，高压静电除尘器设置一、二级捕集器, 捕集器为空穴贮藏式结构，其中心电极上装有电极扰流器，过滤器、反应器。用此方法解决传统技术中尾气净化不彻底，及器具容易堵塞的问题。另有采取滤芯由涂覆有贵金属催化剂的合金金属薄片支架和金属纤维膜隔层卷绕焊接或拼装而成，金属薄片支架轧制成一定的几何形状，涂覆贵金属催化剂的金属薄片支架与金属纤维膜间隔层叠制成滤芯，使通过支架的尾气气流通过尾气槽时，压力、方向产生变化，气流被迫通过一侧高透气率的金属纤维膜，使炭烟微粒被金属纤维膜捕集后燃烧，解决发动机碳颗粒排放问题，这些技术只能将碳颗粒在发动机排气***内燃烧，由此产生的热能没有参加做有用功，对环境产生热污染和无用功 C0₂排放。 The reactor is made into a layered structure, the ceramic filter body is wound by two inner and outer cup-shaped sleeves, the electric heater is automatically compensated by temperature to reach the carbon oxidation temperature, and the high-voltage electrostatic precipitator is provided with a secondary trap, a trap. For the hole storage structure, the center electrode is provided with an electrode spoiler, a filter, and a reactor. This method is used to solve the problem that the exhaust gas purification is not complete in the conventional technology, and the appliance is easily blocked. In addition, the filter element is formed by welding or assembling an alloy metal foil support coated with a precious metal catalyst and a metal fiber membrane spacer, and the metal foil support is rolled into a certain geometry, and the metal foil support and metal coated with the precious metal catalyst are used. The fiber membranes are laminated to form a filter element, so that when the exhaust gas flowing through the stent passes through the exhaust gas groove, the pressure and direction change, and the airflow is forced to pass through the metal fiber membrane with high gas permeability, so that the soot particles are trapped by the metal fiber membrane. Combustion, solving the problem of engine carbon particle emissions, these technologies can only burn carbon particles in the engine exhaust system, and the resulting heat energy does not participate in useful work, causing thermal pollution and useless C0 ₂ emissions to the environment.

本发明之前的内燃发动机碳颗粒催化燃烧装置，无一例外都是安放在发动机排气口外，由于碳烟颗粒的热氧化温度高达 550〜600°C，而柴油车的排气温度为 175〜400°C。为了降低碳烟燃烧温度，其中一个解决的办法就是使用，以催化剂为基的 DPF。在 DPF中使用的催化剂应该在实际工作条件下显示出良好的活性，稳定性和耐久性。尽管世界各先进国家的科学家经过三十多年的探索和研究，但尚未找到一种像汽油机用的三效催化剂那样十分有效的碳烟氧化催化剂。利用本发明内燃机燃烧室内催化燃烧催化剂离子注入方法，使碳颗粒完全在发动机燃烧室内燃烧，碳颗粒燃烧的能量全部用来做功，因此，该技术提高柴油的燃烧效率，燃油量相同时，提高柴油发动机的功率输出；输出同样功率时，可减少柴油的使用量，节约能源。柴油更充分的燃烧，还意味着有害气体排放降低，减少空气污染。由于发动机内的游离碳燃烧充分，减少发动机零部件积碳，减少机械磨损，减少润滑油污染，可延长润滑油使用寿命；减少发动机进、排气门积碳，可防止发动机漏气，保持发动机输出功率，不随使用时间的延长而降低，进而延长柴油发动机的使用寿命。催化燃烧提高柴油机的灵敏响应度，柴油的空气扩散速率比汽由慢得多，柴油的燃烧速度也比汽油慢得多，这是柴油机比汽油机安全，不易产生自然、烧毁车辆的内在因素；柴油机不能像汽油发动机那样通过进气负压来吸进混合气，而是需要通过高压油泵来将雾化的柴油喷入汽缸内，才能与空气充分混合。由于柴油的起燃点低，氧化反应阈值比汽油高很多，这使得柴油混合气点燃的速度要慢于汽油混合气，常规的柴油发动机响应慢，低温点火困难、柴油车总是慢半拍是柴油燃烧特性造成说的。柴油机燃烧室内离子注入催化剂，可降低柴油、及游离，碳燃烧的反应阈值，因此，催化燃烧可增加柴油机的反应速度，使柴油机响应时间接近汽油机。催化燃烧可使柴油车等红灯启动时，书像汽油机一样，动作灵敏。催化燃烧可以降低柴油机爆震幅度，由于柴油与汽油的特性差异，导致柴油发动机的整体设计与汽油发动机完全不一样，传统的柴油发动机扭矩很大，可靠性也非常高，但功率小、而且，其震动噪音大，柴油发动机是靠压燃点火发动的，也就是在压缩行程的末端，被压缩的空气产生高温高压以后，油泵将柴油以雾状喷入汽缸内自燃。这种 "点火"方式如果发生在汽油发动机上，就相当于爆震。事实上，柴油发动机的爆震是不可避免的，它需要靠这种方式来实现混合物的点燃。柴油发动机之所以震动和噪音明显大于汽油发动机，主要就是基于这个原因。对于爆震本身任何内燃机都是不希望看到的。对于柴油发动机而言，它的点火依靠爆震，但作为设计师则希望这个爆震控制在能够点火的临界点即可。多余的爆震自然会增加震动和噪音，乃至影响工作效率。爆震的冲击波可瞬间熄灭油气燃烧，产生未充分燃烧的碳氢化合物、游离碳，而这些燃料遇到发动机内过度金属氧化物催化剂时，可继续氧化燃烧膨胀做功，即提高燃料的利用率，又可减少做功的间歇时间，延长做工持续时间，使爆震幅度降低。发明内容 The carbon particle catalytic combustion device of the internal combustion engine before the present invention is placed outside the exhaust port of the engine without exception, since the thermal oxidation temperature of the soot particles is as high as 550 to 600 ° C, and the exhaust temperature of the diesel vehicle is 175 to 400. °C. One solution to reduce soot combustion temperatures is to use a catalyst-based DPF. The catalyst used in the DPF should exhibit good activity, stability and durability under actual operating conditions. Although scientists from advanced countries in the world have been exploring and researching for more than 30 years, they have not found a very effective soot oxidation catalyst like the three-way catalyst for gasoline engines. By using the method of ion injection of catalytic combustion catalyst in the combustion chamber of the internal combustion engine of the present invention, the carbon particles are completely burned in the combustion chamber of the engine, and the energy of burning the carbon particles is all used for work. Therefore, the technology improves the combustion efficiency of the diesel fuel, and when the fuel quantity is the same, the diesel fuel is improved. Engine power output; when outputting the same power, it can reduce the amount of diesel used and save energy. More complete combustion of diesel also means lower emissions of harmful gases and less air pollution. Since the free carbon in the engine is fully burned, the carbon content of the engine parts is reduced, the mechanical wear is reduced, the lubricating oil pollution is reduced, and the service life of the lubricating oil can be prolonged; Reduce engine carbon deposits in the intake and exhaust valves, prevent engine air leakage, maintain engine output power, and do not decrease with the use of time, thus extending the life of diesel engines. Catalytic combustion improves the sensitive responsiveness of diesel engines. The air diffusion rate of diesel is much slower than that of steam. The burning speed of diesel is also much slower than that of gasoline. This is the inherent factor that diesel engines are safer than gasoline engines and are not easy to produce natural and burned vehicles. It is not possible to suck in the mixture by the suction negative pressure like a gasoline engine. Instead, the high-pressure oil pump is required to spray the atomized diesel into the cylinder to be sufficiently mixed with the air. Due to the low ignition point of diesel, the oxidation reaction threshold is much higher than that of gasoline. This makes the diesel mixture ignite faster than the gasoline mixture. The conventional diesel engine responds slowly, the low temperature ignition is difficult, and the diesel vehicle is always slow. The burning characteristics are said to be. Ion injection of catalyst in the combustion chamber of the diesel engine can reduce the reaction threshold of diesel and free carbon combustion. Therefore, catalytic combustion can increase the reaction speed of the diesel engine and make the response time of the diesel engine close to that of the gasoline engine. When the catalytic combustion can start a red light such as a diesel car, the book is as sensitive as a gasoline engine. Catalytic combustion can reduce the knocking range of diesel engines. Due to the difference in characteristics between diesel and gasoline, the overall design of diesel engines is completely different from that of gasoline engines. Traditional diesel engines have large torque and high reliability, but the power is small and The vibration noise is large, and the diesel engine is started by the ignition ignition, that is, at the end of the compression stroke, after the compressed air generates high temperature and high pressure, the oil pump sprays the diesel into the cylinder and spontaneously ignites. This "ignition" method, if it occurs on a gasoline engine, is equivalent to knocking. In fact, the knocking of diesel engines is inevitable, and it is necessary to achieve ignition of the mixture in this way. The reason why diesel engines are significantly more vibrating and noisy than gasoline engines is mainly for this reason. Any internal combustion engine for the knock itself is not desirable. For diesel engines, its ignition relies on knocking, but as a designer it is hoped that this knock control will be at the critical point where ignition can occur. Excessive knocking naturally increases vibration and noise, and even affects work efficiency. The shock wave of knocking can instantly extinguish the oil and gas combustion, and produce insufficiently burnt hydrocarbons and free carbon. When these fuels encounter excessive metal oxide catalysts in the engine, they can continue to oxidize and burn and expand work, that is, improve fuel utilization. It can also reduce the intermittent time of work, prolong the duration of work, and reduce the knocking range. Summary of the invention
