    Abstract: The enclosed disclosure relates to vehicle systems in which an engine, a particulate filter fluidly coupled with the engine, a selective catalytic reduction (SCR) system fluidly coupled with the engine downstream of the particulate filter, an electrical heating device implemented with the particulate filter, and a controller operatively coupled with the engine and the electrical heating device, are implemented. The controller can detect, when the engine is turned off, a condition for turning on the engine, detect a temperature of the particulate filter of the SCR system, activate the electrical heating device in response to the detected temperature being below a lower temperature threshold, and turn on the engine in response to the detected temperature being at or above the lower temperature threshold.

    Abstract: An apparatus includes an engine load module structured to detect an engine operating state of the engine and generate an engine status report; a timing module structured to receive the engine status report and generate a cylinder request after the engine has been in a certain engine operating state for a certain period of time; and a cylinder module structured to receive the cylinder request and generate a cylinder command to be sent to the engine to deactivate a portion of combustion cylinders based on the engine operating state existing for the certain period of time.

    Abstract translation: 一种装置包括：发动机负载模块，其构造成检测发动机的发动机运转状态并产生发动机状态报告; 定时模块，被构造成在发动机处于某一发动机运行状态一段时间之后接收发动机状态报告并产生气缸请求; 以及气缸模块，其被构造成接收所述气缸请求并产生要发送到所述发动机的气缸命令，以基于在所述特定时间段内存在的所述发动机运行状态来停用燃烧气缸的一部分。
