利用启发式智能优化控制方法建立了基于降低柴油机排放和油耗率的优化控制模型，并在一台卡车用高速直喷式柴油机上通过调节变截面涡轮开度和喷油定时实现了降低NOx排放量和油耗率的控制策略。
Based on the heuristic intelligent optimization control method, an optimal control model based on reducing diesel emissions and fuel consumption was established. In a truck with high-speed direct-injection diesel engine, the NOx emissions were reduced by adjusting the variable-turbine opening and injection timing And fuel consumption control strategy.
