New energy engine helps the development of the automobile industry. The UEFA Champions League liveautomobile industry has experienced hundreds of years of development since its birth. With the increasing awareness of people's environmental protection, new energy vehicles have gradually become people's first choice. The development of new energy engines has become an important direction to promote the development of the automobile industry. This article will discuss the current situation and future of new energy engines to help the development of the automobile industry from the perspective of the definition, development process, advantages and trends of new energy engines. I. NewDefinition and development process of energy engines. Compared with traditional automotive fuel engines, the energy used by new energy engines is more environmentally friendly and energy-saving. New energy engines in a broad sense include not only electric drive, fuel cells, hybrid power, etc., but also hydrogen engines, liquefied natural gas, etc. The development process of new energy engines can be roughly divided into the following stages: 1. In the early stage of the development of the traditional automobile industry (19th century to the 1970s): fuel engine is the only choice; 2. The automobile industry gradually changed from fuel to electric (1960s-1980s): the emergence of electric vehicles and hybrid vehicles; 3. Exploration of new technologies (1980s and 90s): Oil-electric hybrid power became a hot trend in the automobile industry at that time; 4. New energy vehiclesRapid development (from the beginning of the 21st century to the present): fuel cells, pure electric vehicles, hydrogen engines, etc. have begun to enter the market. II. Advantages of new energy engines Compared with traditional fuel engines, new energy engines have the following advantages: 1. Environmental protection and energy saving: Of the fuel burned by traditional fuel engines, only about 30% of the energy is converted into useful energy; while the loss of energy conversion of new energy engines such as electric vehicles is very small, and the efficiency of fuel has been improved from 30%-40% to 60%-70%. Two. High efficiency: The new energy engine can make a fast abnormal sound without acceleration, the power transmission is softer, and the operation is easier. 3. Easy to maintain: Due to the different structure of new energy engines, maintenance will be easier. Four. Low noise: The new energy engine is quiet and will not cause great interference to the surrounding environment and residents, which is especially suitable for urban travel.5. Renewable: The energy used by new energy engines can be recycled, reducing dependence on non-renewable energy. III. The trend of new energy engines. Although the advantages of new energy engines are more obvious than those of traditional fuel engines, they still have some limitations. At present, the research and development cost of new energy engines is relatively high, which limits their promotion in the market. In addition, the construction of charging facilities such as charging and power exchange is also insufficient, which limits the promotion of new energy vehicles in the market. The future development trend of new energy engines mainly has the following two directions: 1. Multi-technology integration: At present, there are many new energy engine technologies. In the future, a combination of multi-technology will be adopted to improve engine efficiency and reliability, such as hybrid turbocharging, hydrogen fuel cells, etc. Two. Sustainable development: new energy enginesThe development needs to be based on sustainability. The future development direction is mainly to establish more perfect charging facilities and more efficient energy storage technology to ensure that new energy engines have the foundation for sustainable development. Conclusion As a new hot technology in the automobile industry, new energy engines are a sign of the future development trend of the automobile industry. Although there are still many problems to be solved, its advantages are obvious. In the future, with the continuous improvement of technology and the continuous maturity of the market, new energy engines will become more popular, making our cities more fresh and livable.
