hydrogen engine meaning in Chinese
液氢发动机
Examples
- The researches on theoretic cycle lay the basis for researches on practical cycle of hydrogen engines
为氢发动机实际循环的动力性和经济性的改善指明了方向。 - Each has a liquid - hydrogen engine that delivers 650 , 000 pounds of thrust , almost twice the power of a space shuttle ' s main engine
每一个推进器都有一个液氢发动机，该发动机每个提供65万磅推进力，将进是现行太空飞船的主发动机两倍推力。 - In the second chapter , firstly , based on the analysis of theoretic cycle of hydrogen engine , the relations between state parameters in four strokes are established
以氢燃料发动机的理论循环为基础，进行了各工作过程状态参数的计算分析，得出了描述理论循环动力性和经济性，即平均指示压力和热效率的表达式。 - Moreover , it has been pointed out that the hydrogen engine used in ? cylinder injection with high pressure can increase volumetric efficiency and compression ratio , - therefore , the performance indexes in this engine , such as output power , thermal efficiency , range of thickness of mixture with normal operation and nox emission , can be improved , and it is possible for the engine to realize rapid combustion of thin mixture , so abnormal combustion , such as backfire , pre ? ignition , can be controlled effectively
指出了采用内部混合气形成方式且高压喷射的氢发动机，有利于提高充气效率和压缩比，从而改善发动机的动力性和经济性；有利于扩展发动机正常工作的浓度范围；并且有利于实现稀薄混合气快速燃烧，从而可以有效地抑制早燃、回火及爆燃等异常燃烧和no _ x排放量。试验指出了发动机的点火正时、喷射正时及喷氢量对发动机的性能、异常燃烧、 no _ x排放量有很大影响。
