【摘要】 掺氢燃烧为传统汽油汽车的节能与减排提供了可靠途径。但当前加氢设施尚不完善，储氢装置制造困难以及随车运氢不安全等问题严重阻碍了掺氢发动机汽车的快速发展及商业化应用。针对上述问题，本研究设计出了搭载电解水制氢装置的发动机系统。将电解水产生的氢气和氧气分别通入到发动机以及进气管道中，提出了发动机掺氢掺氧燃烧模式。在此基础上采用GT-POWER仿真软件对该掺氢掺氧燃烧模式下发动机的性能进行了仿真分析，结果表明相比于纯汽油以及掺氢燃烧模式，发动机在掺氢掺氧燃烧模式下具有更加优良的经济性、动力性和排放特性。且随着掺氢和掺氧速率的提高，发动机的各项性能均能够进一步增强。更多还原

【Abstract】 Hydrogen-blended combustion provides a reliable way for energy saving and emission reduction of traditional gasoline vehicles. However,the imperfect filling hydrogen facilities, manufacturing hardships of hydrogen storage device and insecurity of hydrogen transportation on vehicles seriously hinder the development of the hydrogen-blended engine vehicles. In view of the above problems,this research designed an engine system equipped with water electrolysis hydrogen generation device. The hydrogen and oxygen produced by water electrolysis are introduced into the engine and intake pipe,respectively,then the hydrogen and oxygen blended combustion mode is proposed. On this basis,the GT-POWER simulation software was used to simulate the performance of the engine under the hydrogen and oxygen blended combustion mode. The results show that compared with pure gasoline and hydrogen-blended combustion mode,the engine under the hydrogen and oxygen-blended combustion mode has the better economic and dynamic performance as well as the emission characteristics. Furthermore,with the increasing of the blended rate of hydrogen and oxygen,the performance of the engine is further enhanced.更多还原
