【摘要】 本文介绍了不同转速、负荷下点火提前角、空燃比和EGR 率对EQ6100汽油机性能和NO_x 排放影响的研究。优化这三个参数,组织快速燃烧,用多火花点火,可使该发动机在功率、燃油经济性基本不变的情况下,大幅度降低NO_x 排放。更多还原

【Abstract】 in this paper, the effects of spark timing, air fuel ratio and EGR rateon the performance and NOx emission of a Model EQ6100 gasoline engine are studi-ed at various speeds and loads. By optimizing the:three parameters, organizingfast burning and using multi-spark ignition, the NOx emission of the engine can begreatly decreased without suffering power output and fuel economy penalty.更多还原
