摘要
能源开发格局,动力机的系统结构对人类社会的发展起着至关重要的作用。以石油为主的第三代能源正面临着枯竭的危险,生物能作为一种储量丰富、可经济开发的清洁能源越来越受到人们的重视。作为动力机主力军的内燃机也在经受能源危机、环境的考验。鉴于目前状况,从生物技术和仿生技术的角度,结合生物质能的开发利用途径,提出了生物动力机这个概念,并对其做了较为详细的限定描述,阐明了生物动力机和内燃机的本质区别,分析了生物动力机的优点和开发途径。
The structure and distribution of energy sources and the system of the prime motor used are of the utmost importance to the development of the human society. Nowadays a shortage of fossil fuels, especially crude oil, faces the world, while the bio-energy, as a kind of clean energy, has vast reserves to be exploited economically, and much importance has thus been attached to it. Moreover, the internal-combustion engine, with its relatively lower efficiency and higher emissions, has been standing a severe test due to the energy crisis and the environmental problem. Based on biology and bionics,the definition of the biological engine is suggested, and a detailed restrictive description is provided as well. The essential differences between a biological engine and a internal-combustion engine are illustrated. In addition, the merit of the biological engine and the method for its development are depicted.
