1氢气发动机存在的问题及解决在研究构思以氢气作为汽车发动机的燃料时有两个主要问题，一是选择什么样的混合方式，以保证发动机离的工作效率；二是氢燃料的储存系统。混合方式上大都倾向于外部混合，混合前氢气的压力一般不超过03～05MPa。但外部混合方案实际上并不是尽善尽 A hydrogen engine problems and solutions There are two main problems in the study of the concept of hydrogen as a vehicle engine fuel, one is to choose what kind of hybrid approach to ensure the efficiency of the engine from the work; the second is the hydrogen fuel storage system. Most of the mixing methods tend to external mixing, hydrogen pressure before mixing generally not exceed 03 ~ 05MPa. But external mixing programs are not actually perfect
