Engine technology of hydrogen-oxygen mixture With the increasing global climate change,HS code categorization for finished goods environmental protection has become a common responsibility of mankind. In order to reduce environmental pollution and relieve energy pressure, scientists are constantly researching new engine technologies, in which hydrogen engines are considered to be the future direction. Hydrogen engine is a kind of engine that mixes hydrogen and oxygen and burns to generate power. Its advantages are environmental protection, high efficiency, energy saving and other aspects.This article will introduce in detail the principle, structure and future development prospects of hydrogen engines. I. Principle The working principle of the hydrogen-oxygen engine is to mix hydrogen and oxygen and burn to produce high-temperature and high-pressure gas to drive the piston movement, thus driving the engine to work. Among them, the ratio of hydrogen and oxygen is the key. The general ratio is 2:1, that is, every two parts of hydrogen mixed with one oxygen, which can ensure adequate combustion while reducing pollutants produced by incomplete combustion. II. The structure of the hydrogen engine is very different from that of the traditional fuel engine. Traditional fuel engines need fuel injectors, fuel pumps, nozzles, etc., while hydrogen engines need hydrogen storage tanks, oxygen storage tanks, reactors, etc. Specifically, hydrogen storage tanks and oxygen storage tanks are used to store hydrogen and oxygen, and enough hydrogen and oxygen need to be added before the engine starts.The reactor needs to be installed at the mixing point of hydrogen and oxygen to control the mixing ratio and the rate of combustion. In addition, it is necessary to transmit the high-temperature and high-pressure gas generated by the reactor to the piston through the transmission system, so as to achieve the normal operation of the engine. III. Advantages Hydrogen engines have many advantages over traditional fuel engines. First of all, the emissions of the hydrogen engine are water and a small amount of oxygen, which greatly reduces environmental pollution. Secondly, the efficiency of hydrogen-oxygen fuel is much higher than that of traditional fuel. Under the same power output, the fuel consumption of hydrogen-oxygen engines is much lower than that of traditional fuel engines. In addition, the hydrogen-oxygen engine will not produce soot, ozone and other pollutants during operation, and it is also convenient to maintain. IV. Challenge Hydrogen engines face some challenges in their application, the most important of which is the storage and transportation of hydrogen.Hydrogen is a highly flammable and explosive gas that requires strict pipes, valves and storage accessories to ensure safety, which also increases the cost of use. In addition, it is also necessary to study how to integrate and control the control system to ensure the efficient operation of the engine and control the mixing ratio and combustion speed. This will challenge the difficulty of design and manufacturing. V. Prospects Generally speaking, the prospect of hydrogen engines is very broad, especially in the new era of energy constraints and environmental protection. Although the development of hydrogen engines still faces challenges, there have been enterprises working overtime to develop the technology of hydrogen engines, including Toyota and other large companies, which have also begun to lay out in this field, and took the lead in launching hydrogen energy products such as hydrogen fuel vehicles. Hydrogen and oxygen engines have gradually received the attention and recognition of the market. In the future, governments and relatedThe department will invest more and more in hydrogen engines, and its development prospects will become broader and wider. In summary, the hydrogen engine has become one of the future development directions due to its many advantages such as environmental protection, energy saving and high efficiency. Although it still faces many challenges in technology and the market, based on society's increasing attention to environmental protection and energy management, it is believed that hydrogen oxygen engines will be further promoted and developed, and become the leader in the new era.
