An emissions management system for an engine in a hybrid powertrain system includes a sensor assembly and a controller. The sensor assembly is configured to provide an activation signal and detect emissions information in response to an engine start event, including information indicative of engine power, driver demand power, catalyst temperature, battery state of charge, and battery temperature. The controller is in communication with the sensor assembly and is configured to: receive the activation signal and in response receive emissions information from the sensor assembly; determining an emission reduction mode, the emission reduction mode having a threshold for a catalyst temperature and having an engine power corresponding to the emission reduction mode; monitoring emission information; comparing the catalyst temperature to a threshold value; operating the engine in an emission reduction mode when the catalyst temperature is below a threshold; and allowing the engine to operate in a normal operating mode when the catalyst temperature is greater than or equal to the threshold.
用于混合动力系统中发动机的排放管理系统包括传感器组件和控制器。所述传感器组件被配置成响应于发动机启动事件而提供激活信号并且检测排放信息,包括指示发动机功率、驾驶员需求功率、催化剂温度、电池荷电状态和电池温度的信息。控制器与传感器组件通信并且被配置成:接收激活信号,并且作为响应而从传感器组件接收排放信息;确定减排模式,所述减排模式具有针对催化剂温度的阈值并且具有与所述减排模式相对应的发动机功率;监测排放信息;将催化剂温度与阈值进行比较;当催化剂温度低于阈值时,使所述发动机以减排模式操作;以及当催化剂温度大于或等于所述阈值时,允许所述发动机以正常操作模式操作。
