Embodiment Construction
[0019] The following instructions refer to operating the engine system (as in figure 1 Systems and methods for a particulate matter (PM) sensor or a soot sensor in an engine exhaust line downstream of a lean NOx trap (LNT) in an engine system of an engine system. A PM sensor configured with a pair of interdigitated electrodes can be Figure 2A to Figure 2B The multiple switches shown in are connected to positive voltage and ground. The controller can be configured to execute programs (eg, image 3 program) to change the switch position of the soot sensor in LNT and soot sensor based operation mode. The controller can also be configured to execute programs (eg, Figure 4 program) to operate the soot sensor in the particulate matter detection mode and regenerate the soot sensor based on the soot load on the soot sensor. Additionally, the controller may intermittently estimate the exhaust NOx level and SOx level of the LNT and execute routines (eg, Figure 5 program) to rege...
