Internal Combustion Engine Alternative Fuels

With the increasing concern for environmental protection and sustainable development, alternative fuels for internal combustion engines have become a topic of great concern. Traditional fuels such as oil not only have the problem of emission pollution, but also have the problem of limited quantity and easy to be influenced by political factors. Therefore, finding suitable alternative fuels is an important guarantee to ensure the sustainable development of people's lives and society. In recent years, some new fuels have been developed, such as biomass energy, hydrogen fuel, methanol, etc. The development and use of these alternative fuels can reduce the impact of traditional fuels on the environment and reduce dependence on fossil energy. However, the research and use of alternative fuels also presents a series of problems, such as cost, energy density, sustainability, and so on. Therefore, the performance, feasibility, advantages and disadvantages of alternative fuels need to be fully studied and evaluated. On the basis of existing research, this paper will conduct an in-depth discussion from the aspects of combustion characteristics, emission characteristics, advantages and disadvantages of alternative fuels, so as to provide certain theoretical support and practical experience for the research and application of alternative fuels, and promote the development and application of alternative fuel technology.
