Next Steps for ISM Next Steps for ISM DevelopmentDevelopment

Cummins has expressed a desire to Cummins has expressed a desire to move toward a higher level of soot in move toward a higher level of soot in the ISM test (6.0 min)the ISM test (6.0 min) This will require a modification to the This will require a modification to the

original matrix design. Additional tests original matrix design. Additional tests that will help develop a soot correlation that will help develop a soot correlation from 5.5% to 6.5% are now being built into from 5.5% to 6.5% are now being built into a revised matrix plan.a revised matrix plan.

Next Steps for ISM Next Steps for ISM DevelopmentDevelopment

Questions remain about the ability of the Questions remain about the ability of the ISM to be a full replacement test for the ISM to be a full replacement test for the M11-EGR and M11 HST. Pending the M11-EGR and M11 HST. Pending the outcome of phase 2 of the test matrix, outcome of phase 2 of the test matrix, there are two paths forward.there are two paths forward. Path 1 – data shows appropriate Path 1 – data shows appropriate

discrimination and correlation such that the discrimination and correlation such that the ISM is a suitable replacement for the M11-ISM is a suitable replacement for the M11-EGR/HSTEGR/HST

Path 2 – Continue to use M11EGR for current Path 2 – Continue to use M11EGR for current category and use ISM for PC10. category and use ISM for PC10.
