Purpose: To investigate the emissions (CO, HC, NOx, PM, N2O, CH4, CO2), J1939 broadcast signal, and 

 (A) Obtain engine torque curve and record all engine specs (rated rpm/torque, displacement, m

 (B) 28 steady-state modes and idle 

 (C) Triplicate runs of both cold/hot FTP and WHTC transient cycles 

-Run ULSD fuel (~10 ppm sulfur)

-Take PM filters for transient cycle(s)

Denormalization:Per Part 1065 (for HD GHG purposes) and Part 86 (for compliance and comparison purposes)

Plan: Test Sequence:

a) Daily sequence (cold FTP - soak - hot transient cycles in triplicates [refer to c and d below])

b) Manually run 29 modes [Idle + 28 modes] and log data: emissions and fuel mass rate (includin

c) Transient Cycle FTP (in triplicates) (emissions and fuel mass rate)

d) Transient Cycle WHTC (in triplicates) (emissions and fuel mass rate)

Day 1 run torque curve and then prep engine/ aftertreatement with an FTP

Day 2 Cold FTP-soak-hot FTP (triplicate runs) + steady-state modes, prep with FTP at end of day

Day 3 Cold FTP-soak-hot FTP (triplicate runs) + finish steady-state modes
