一种新的内燃机理论循环

对内燃机的前景作出评价 ,认为它还有数十年寿命 ,而且还有改善余地。提出一种新的内燃机理论循环 ,即刘氏循环。新的理论循环消除了氧化氮 (NOx)生成的根源 ,而且 ,取消了内燃机的进气和压缩行程 ,提高了热效率。在机构上可以沿用往复式内燃机的大部分结构 ,而且有所简化。

A New Theoretical Cycle of the Internal Combustion Engine

The prospect of the internal combustion engine is evaluated,indicating the service life is around several tens of years and there are still some areas left to be improved.A new theoretical cycle of the internal combustion engines, i.e.Liu's Cycle, is put forward, which eliminates the NOx generating source and the induction and compression strokes of the internal combustion engines, and improves heat effeciency.Most structures of the internal combustion engines are still used but some of the structures are simplified.
