摘要:
为提高发动机动力性并减少 NOx排放,采用GT-Power对某型发动机进行整机建模,并列出主要组件.根据发动机几何结构参数设置各组件的对应属性和参数,在发动机进气氧空比分别为正常值,以及20%,24%,25%及30%条件下进行了动力性能与 NOx排放仿真实验.实验结果表明:随着氧空比增大,发动机额定功率与扭矩增大;当进气氧空比超过25%时,NOx排放急剧增大.
Abstract:
In order to improve the dynamic performance and reduce NOx emission from the engine, the whole model for a certain type of engine is built with GT-Power, and the main components are displayed in the model. The corresponding properties and parameters for the components are set according to the geometry structure parameters of the engine, and the simulation on dynamic performance and NOx emission under oxygen-air ratios of normal value, 20%, 24%, 25% and 30% for the engine intake is achieved. The simulation results show that the rated power and torque of the engine increase with the increasing of oxygen-air ratio, but the NOx emission increases sharply when oxygen-air ratio is over 25%.
