Left image - This 200-hour procedure uses a Cummins ISM engine equipped with EGR and is intended as a replacement procedure for the M-11 EGR, using newer hardware.

The Cummins ISM lubricant procedure is approved for API CJ-4 and Cummins CES-20081, Mack E0-0 Premium Plus. It is a replacement procedure for Cummins M-11 EGR.

 

The Cummins ISM procedure is used to evaluate a lubricant's effectiveness at reducing soot-related wear of overhead components, sludge, and oil filter plugging.

 

High-load, heavy-duty field conditions with high soot and exhaust gas recirculation (EGR) flow rates using a 2007 emission-compliant engine are simulated.

 

Cummins ISM Equipment and Procedure

This 200-hour procedure uses a Cummins ISM engine equipped with EGR and is intended as a replacement procedure for the M-11 EGR, using newer hardware. The Cummins ISM procedure uses PC-10 fuel.

 

The parts evaluated include:

  • Sludge

  • Injector adjusting screw

  • Crosshead

  • Oil filter plugging

  • Top ring for wear

Procedure Results

Cummins ISM lubricant procedure evaluates oil filter plugging.

 

Used lubricant samples are analyzed for:

  • Viscosity

  • Total base number (TBN)

  • Total acid number (TAN)

  • Wear metals

  • Soot
