摘　　要：将米勒循环和EGR技术相结合,研究二者综合使用降低NO_x排放的同时保持燃油经济性的潜力。开展了不同米勒正时结合低压和跨级EGR系统的负荷特性及推进特性工况试验,得到了推进特性和发电特性在NO_x排放满足IMO Tier Ⅲ要求下的最佳经济性控制策略。并进一步研究了针对万有特性的综合减排措施控制策略及效果。EGR and Miller cycle were combined to study its potential on reducing the NO, emission and maintain the fuel efficiency at the same time. The control strategies for optimized fuel efficiency under the constraints of IMO Tier Ⅲ NOx emission regulation were obtained by engine propulsion and generation characteristics tests, which were carried out under various combination of Miller timing and EGR type and degrees. The combined control strategies and its effect regarding to universal characteristics were also studied.
