Abstract

The article presents synthetically the methods of ignition of the air-fuel mixture in Internal Com-bustion (IC) engines along with the characteristics of their advantages and disadvantages, the problems of their use and the possibility of development. The further development of piston engines will require a drastic reduction in the emission of harmful exhaust components and carbon dioxide, which is the most important greenhouse gas emitted by IC engines. For this reason, not only the engines themselves must be changed but fuels as well. For the most effective use of them, self-ignition of a homogeneous fuel-air mixture should be implemented. In the present state of technical development is not possible to widespread use the most ad-vanced ways of self-ignition methods. Typical homogeneous charge compression ignition (HCCI), where an engine uses only one type of the fuel and correctly self-ignite in the full scope of work is still not implemented in a serial production. In the foreign literature, there is a significant number of publications on various methods of Compression Igni-tion (CI) in IC engines, including IC in Dual Fuel (DF) engines. The Polish literature, however, is extremely sparse in this matter, and one can find a number of works on CI in single-fuel engines [1-10], but the topic of DF fueling is not too extensively described. For this reason, it seems important to publish an article on this important topic today.

均质混合气内燃机是活塞式内燃机进一步发展的关键
本文综合介绍了各种内燃机空气燃料混合气点火方法的特点、优缺点、使用中存在的问题和发展的可能性。活塞式发动机的进一步发展将需要大幅减少有害废气成分和二氧化碳的排放,二氧化碳是内燃机排放的最重要的温室气体。因此,不仅发动机本身必须更换,燃料也必须更换。为了最有效地利用它们,应该实现均匀的燃料-空气混合物的自燃。在目前的技术发展状态下还不可能广泛使用最先进的自燃方法。典型的均质装药压缩点火(HCCI),即发动机只使用一种燃料并在全工作范围内正确自燃,目前仍未在批量生产中实现。在国外文献中,有相当数量的关于内燃机压缩点火(CI)的各种方法的出版物,包括双燃料(DF)发动机的压缩点火(CI)。然而,波兰在这方面的文献非常少,人们可以找到许多关于单燃料发动机CI的作品[1-10],但DF燃料的主题并没有得到太广泛的描述。因此,今天就这个重要的话题发表一篇文章似乎很重要。关键词:内燃机,内燃机,均质混合气,双燃料发动机,RCCI,双燃料,HCCI,发动机,PCCI, PPCI, PCI, SPCCI, saci。本文综合介绍了内燃机中空气燃料混合气点火方法的特点,优缺点,使用中存在的问题和发展的可能性。活塞式发动机的进一步发展将需要大幅减少有害废气成分和二氧化碳的排放,二氧化碳是内燃机排放的最重要的温室气体。因此,不仅发动机本身必须更换,燃料也必须更换。为了最有效地利用它们,应该实现均匀的燃料-空气混合物的自燃。在目前的技术发展状态下还不可能广泛使用最先进的自燃方法。典型的均质装药压缩点火(HCCI),即发动机只使用一种燃料并在全工作范围内正确自燃,目前仍未在批量生产中实现。在国外文献中,有相当数量的关于内燃机压缩点火(CI)的各种方法的出版物,包括双燃料(DF)发动机的压缩点火(CI)。然而,波兰在这方面的文献非常少,人们可以找到许多关于单燃料发动机CI的作品[1-10],但DF燃料的主题并没有得到太广泛的描述。因此,今天就这个重要的话题发表一篇文章似乎很重要。关键词:内燃机,CI发动机,均质混合气,双燃料发动机,RCCI,双燃料,HCCI,发动机,PCCI, PPCI, PCI, SPCCI, SACI
