| Abstract:EGR and Miller cycle were combined to study its potential on reducing the NOx 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. |
