进入新世纪,人类工业技术的发展已达到空前高度,虽然如此,在汽车、动力、能源和环境污染等方面仍存在着很多难以解决和无法回避的问题。内燃机的发明为汽车等的发展提供了最适合的动力装置,但不超过45%(汽油机更低)的有效热效率,使汽车消耗了大量的宝贵石油资源。同时,内燃机排 In the new century, the development of human industrial technology has reached an all-time high. However, there are still many problems that are difficult to be solved and unavoidable in terms of automobile, power, energy and environmental pollution. The invention of internal combustion engines provides the most suitable power plant for the development of automobiles and the like, but the effective thermal efficiency of not more than 45% (lower gasoline engines) consumes a large amount of precious oil resources. At the same time, the internal combustion engine row
