	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.


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

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

Pass/Fail Criteria

Pass/fail criteria at the end of each procedure include:

Parameter	Anchor	Merit Wt	Max	Min
XHD	5.7	350	7.1	4.3
RWL	100	0	100	0
OFDP	13	150	19	7
IAS	27	350	49	16
Sludge	9	150	9.3	8.7
Merits	1,000
