常見例句To improve the process of fuel automization, vaporization and mixing with air, the bi-swirl aerovalve is preferred to PDE under the condition of low mixture charging velocity. 為了改善燃油霧化、蒸發(fā)和摻混，低充填速度PDE宜采用雙旋流式氣動閥。For the aerovalve with different structure, the resistances of PDE are different, too.The turbulence generator (TG) installed in detonation chamber leads to an increase of resistance. PDE爆震室裝擾流器時阻力增加，不同氣動閥在裝同種擾流器時，其對PDE的阻力影響程度不同，安裝整流柵有利于降低阻力。Experimental Investigation on Mechanism of Swirling Aerovalve and Drag Coefficient of Turbulence Generation in PDE 脈沖爆震發(fā)動機(jī)旋流式氣動閥工作機(jī)理和擾流器阻力特性的實驗研究 返回 aerovalve
