    • A method of controlling an exhaust gas aftertreatment system in a compression ignition engine having a power-assisted turbocharger coupled to a power source. The turbocharger includes a compressor in communication with an intake manifold and a turbine in communication with an exhaust manifold. The method comprises the steps of determining an operating mode of the exhaust gas aftertreatment system selected from the group consisting of a light off mode, regeneration mode, and storage mode. The method then determines a charge value associated with the power source, and engages the power source to the power-assisted turbocharger as a function of the charge value and the operating mode of the exhaust gas aftertreatment system. In one aspect of the invention, negative power is applied to the power-assisted turbocharger to increase the exhaust gas temperature to achieve particulate filter light-off. In another aspect, positive power is applied to the power-assisted turbocharger to reduce turbo-lag or engine pumping losses. In another aspect, negative or positive power is applied to the power-assisted turbocharger to maintain a desired oxygen flow through the particulate filter.
    • 一种在具有耦合到电源的功率辅助涡轮增压器的压缩点火式发动机中控制废气后处理系统的方法。 涡轮增压器包括与进气歧管连通的压缩机和与排气歧管连通的涡轮机。 该方法包括以下步骤:确定从关灯模式,再生模式和存储模式中选择的排气后处理系统的操作模式。 该方法然后确定与电源相关联的电荷值,并且根据废气后处理系统的电荷值和操作模式将电源接合到功率辅助涡轮增压器。 在本发明的一个方面,负功率被施加到动力辅助涡轮增压器以增加废气温度以实现微粒过滤器的关闭。 在另一方面,正功率被施加到功率辅助涡轮增压器以减少涡轮滞后或发动机泵送损失。 在另一方面,负功率或正功率被施加到动力辅助涡轮增压器以保持通过微粒过滤器的期望的氧气流。

    • A method of mapping a direct injection stratified charge (DISC) engine comprises the steps of generating an estimated fueling rate map and torque map from engine steady-state mapping data, generating a transient engine operating trajectory along a predetermined parameter vector toward an associated desired torque, and iteratively modifying the estimated fueling rate map as a function of the generated torque resulting from the transient engine operating trajectory. In one aspect of the present method, the step of iteratively modifying the estimated fueling rate map includes updating the fueling map at each sampling time instant (tk) by applying a current estimated fueling rate associated with the estimated fueling rate map, and determining the engine torque value corresponding to the parameter vector. The torque value is then inverted to update the fueling map as a function of the engine torque value. The method is advantageous because it reduces the time to map a DISC engine torque strategy because calibration is performed with transient engine response data rather than steady-state data.
    • 映射直接喷射分级充电(DISC)发动机的方法包括以下步骤:从发动机稳态映射数据产生估计的加油速率图和扭矩图,沿预定参数向量产生一个瞬时发动机操作轨迹,朝着相关联的期望扭矩 并且根据由瞬态发动机操作轨迹产生的产生的扭矩迭代地修改估计的加油速率图。 在本方法的一个方面,迭代地修改估计加油速率图的步骤包括通过应用与估计的加油速率图相关联的当前估计加油速率来更新每个采样时刻(tk)处的加油图,以及确定发动机 扭矩值对应于参数矢量。 然后扭矩值被反转以根据发动机扭矩值来更新加油图。 该方法是有利的,因为它减少了映射DISC发动机转矩策略的时间,因为校准是用瞬态发动机响应数据而不是稳态数据执行的。
