一种新概念内燃机——基于多孔介质燃烧技术的超绝热发动机

New type of internal combustion engine - Superadiabatic engine based on the porous-medium combustion technique

多孔介质中的超绝热燃烧是一种先进的燃烧技术 ,具有高效低污染的特点。将这一技术应用于发动机领域 ,有可能引起内燃机技术和产业的一场重大革新。介绍超绝热燃烧的概念 ,讨论了多孔介质中往复流动下超绝热燃烧的特点 ,对多孔介质发动机的工作循环作了简单的热力学分析。在此基础上 ,对当前国外超绝热发动机的基础研究进行综述 ,着重介绍了分别由美国、日本和德国提出的三种超绝热发动机的方案的理论和实验研究进展 ,以期引起我国内燃机界对这一发展动向的关注。

Superadiabatic combustion in porous medium (PM) is an advanced combustion technique with high efficiency and low emission. Application of this technique to the internal combustion engine might bring about an innovation in the engine industry. This paper presented a brief introduction to the PM engine. Its working characteristics and outstanding advantages over the conventional engine were described. A survey of current research status in the industrial countries in this area was given.
