摘要:
借助于燃烧闭环控制系统,研究了传统燃烧到低温燃烧的切换过程.试验结果表明:基于循环的燃烧闭环控制系统能够跟踪累计放热50%对应的曲轴转角的阶跃输入,并且能很好地抑制转速、负荷、油轨压力和废气再循环(EGR)等系统干扰.在传统燃烧到低温燃烧的切换过程中,通过燃烧闭环控制系统实时地调节喷油提前角,可以使燃烧相位保持在参考值附近,从而保证了切换过程的燃烧稳定性.

Abstract: Transition from conventional combustion to low temperature combustion was studied by using closed loop combustion control system. The test results reveal that the cyclebased closed loop control system can follow c (crank angle corresponding to 50% of total heat release) step input and restrain system disturbances such as speed, load, rail pressure and exhaust gas recirculation (EGR). During the transition process, fuel injection timing can be adjusted in time to keep the combustion phase at the set point, in other words, combustion stability is ensured.

Key words:  combustion closed loop control, low temperature combustion, transition
