摘要: An after-treatment device that includes a diesel particulate filter (DPF) requiring periodic regeneration includes a sensor providing a signal indicative of a soot accumulation and at least one device providing an operating parameter indicative of a work mode of the machine. A controller determines a soot level and a readiness level based on the work mode of the machine, and further classifies the soot level relative to a desired range for initiating a regeneration event and initiates the regeneration event when the soot level falls within the desired range.

摘要: A fuel delivery system for a vehicle having an engine configured to selectively operate between a port fuel injection (PFI) mode, a gasoline direct injection (GDI) mode, and a port and direct fuel injection (PDI) mode. The fuel delivery system includes a PFI system including plurality of PFI injectors configured to supply fuel to the engine during the PFI mode, and a GDI system including a plurality of GDI injectors configured to supply fuel to the engine during the GDI mode. A fuel system monitor is configured to monitor the fuel delivery system when operating in the PFI mode, and attribute any fuel delivery system malfunctions occurring during the PFI mode to the PFI system alone, and monitor the fuel delivery system when operating in the GDI mode, and attribute any fuel delivery system malfunctions occurring during the GDI mode to the GDI system alone.

摘要: Detecting ash in a diesel particulate filter includes receiving data indicative of signal attenuation for ash-responsive and ash-insensitive RF signals transmitted through a diesel particulate filter containing trapped soot and ash. A difference between the RF signals, such as a difference in signal attenuation, may be leveraged to detect a relative ash loading state or a change in relative ash loading state of the diesel particulate filter, and responsively indicate that filter cleaning is needed.
