【摘要】 概述了我国目前汽车科技创新现状,对纯电动汽车、燃料电池汽车、电动—发电集成机组汽车以及国内外空气汽车,质子交换膜燃料电池汽车进行了客观评论;还特别对现正进行的液氮汽车研制存在的热交换器结霜问题,作了否定分析。重点介绍了液氮汽化,为避免产生结霜,必须先雾化以及汽化器的结构、安装形式和整个吸热增加能量,提高汽车总效率的液氮—氮气循环系统。最后还提及液氮汽车的优越性,生产可行性等。更多还原

【Abstract】 Outlines the updated situation of science and technology innovation in the automobile ndustry in China,makes objective comments on the pure electric vehicles,fuel cell vehicles,electric- power integrated units as well as air powered vehicles at home and abroad,proton exchange membrane fuel cell vehicles;especially makes a negative analysis of the frosting problem in the heat exchanger in the liquid nitrogen car which is under development. Mainly introduces the liquid nitrogen gasification. To avoid frosting,atomization should be implemented first. Also describes the structure of the carburetor,its installation form and liquid nitrogen- nitrogen cycle system which can totally absorb the heat to increase the energy and improve the total efficiency of the car. Finally mentions the superiority of liquid nitrogen vehicle and its production feasibility,etc.更多还原
