1      Aftertreatment Procedure BLOCKED by Aftertreatment History (Unable to Regen Cummins Engine)

2     Aftertreatment History

2.1Aftertreatment History interfering with Cummins Aftertreatment procedure while using insite!

 

Aftertreatment History is designed to display historical records regarding the Aftertreatment System. It records data associated with last 10 active regeneration events (both complete and incomplete). The feature also has two other records that capture data associated with the Maximum Soot Load Condition and the Maximum Diesel Particulate Filter Outlet Temperature Conditions achieved over the life of the engine.

 

To View Aftertreatment History

 

Connect with INSITE™. 

Click Advanced ECM Data on the Viewbar. 

In the Advanced ECM Data select Aftertreatment History

Viewing Data 

  

The top portion of the viewing area contains the Regeneration History Log. The Log will retain up to 10 entries associated with the last 10 complete and/or incomplete active regeneration events. 

The data captured in the Aftertreatment History Log includes:

 

ECM Run Time (Key-On Time) 

ECM Real Time: If Real Time Clock is not available, ECM Real Time will be displayed as "Not Available". 

Starting Diesel Particulate Filter Soot Load: This parameter records the Diesel Particulate Filter Soot Load at the beginning of the regeneration event. There are 4 possible values that can be displayed: Normal, Above Normal - Least Severe, Above Normal - Moderately Severe or Above Normal - Most Severe. 

Ending Diesel Particulate Filter Soot Load: This parameter records the Diesel Particulate Filter Soot Load at the end of the regeneration event. There are 4 possible values that can be displayed: Normal, Above Normal - Least Severe, Above Normal - Moderately Severe or Above Normal - Most Severe. 

Starting Diesel Oxidation Catalyst Inlet Temperature: This parameter gives the temperature at the inlet of the Diesel Oxidation Catalyst at the start of the regeneration event. It records the value in degrees (deg C / deg F). 

Maximum Diesel Particulate Filter Inlet Temperature: This parameter gives the maximum temperature recorded at the inlet of the Diesel Particulate Filter during the regeneration event. It records the value in degrees (deg C / deg F). 

Maximum Diesel Particulate Filter Outlet Temperature: This parameter gives the maximum temperature recorded at the outlet of the Diesel Particulate Filter during the regeneration event. It records the value in degrees (deg C / deg F). 

Maximum Diesel Particulate Filter Differential Pressure: This parameter gives the maximum Diesel Particulate Filter Differential Pressure recorded during the regeneration event. It records the value in Pressure units (kPa / Psia). 

The bottom portion of the viewing area allows the user to view the data associated with either the Maximum Soot Load condition or the Maximum Diesel Particulate Filter Outlet Temperature condition achieved over the life of the engine. These records may not be associated with a regeneration event. 

Both these records (Maximum Soot Load Condition and Maximum Diesel Particulate Filter Outlet Temperature Condition) capture the following data:

 

4      ECM Run Time (Key-On Time). 

ECM Real Time: If Real Time Clock is not available, ECM Real Time will be displayed as "Not Available". 

Diesel Particulate Filter Soot Load: This parameter records the Diesel Particulate Filter Soot Load at the time the condition was recorded. There are 4 possible values that can be displayed: Normal, Above Normal - Least Severe, Above Normal - Moderately Severe or Above Normal - Most Severe. 

Diesel Oxidation Catalyst Inlet Temperature: This parameter gives the temperature at the inlet of the Diesel Oxidation Catalyst at the time the condition was recorded. This monitor reads from Diesel Oxidation Catalyst Inlet Temperature Sensor, which gives the temperature at the inlet of the diesel oxidation catalyst and is usually the first sensor in the aftertreatment system. It records the value in temperature units (deg C / deg F). 

Diesel Particulate Filter Inlet Temperature: This parameter gives the temperature recorded at the inlet of the Diesel Particulate Filter at the time the condition was recorded. This monitor reads from Diesel Particulate Filter Inlet Temperature Sensor, which gives the temperature at the inlet of the diesel particulate filter and is usually the sensor located midway in the aftertreatment system. It records the value in temperature units (deg C / deg F). 

Aftertreatment Diesel Particulate Filter Outlet Temperature: This parameter gives the temperature recorded at the outlet of the Diesel Particulate Filter at the time the condition was recorded. This monitor reads from the Diesel Particulate Filter Outlet Temperature Sensor, which gives the temperature at the outlet of the diesel particulate filter and is usually the last sensor in the aftertreatment system. It records the value in Temperature units (deg C / deg F). 

Diesel Particulate Filter Differential Pressure: This parameter gives the Diesel Particulate Filter Differential Pressure at the time the condition was recorded. I This monitor reads the Diesel Particulate Filter Differential Pressure which is the difference in pressure across the diesel particulate filter. It records the value in pressure units (kPa / Psia).

Right Click Menu 

This feature does not support a right click menu, but there are limited functions available which includes the following

The ability to toggle between displaying The Maximum Soot Load Condition Log and The Maximum Diesel Particulate Filter Outlet Temperature Condition. 

The ability to refresh the display using the Refresh button. 

The ability to print or save the current display using the Print or Save buttons. 

6            Shop Talk: Despite all efforts by technicians to force regeneration or Aftertreatment procedure within the diagnostic program, if you have Aftertreatment History present Aftertreatment procedure WILL NOT run, please delete, errase, clear all aftertreatment history within your cummins insite...only than you will be able to run your aftertreatment procedure!
