Aftertreatment System (ATS)
Aftertreatment System (ATS)
Introduction
The Aftertreatment System (ATS) on your vehicle is made up of two systems:
1.Diesel Particulate Filter (DPF) System
2.Selective Catalytic Reduction (SCR) System
They fulfill two primary functions; particulate reduction & nitrogen oxide (NOx) reduction.
This section of the manual describes how to interact and control these two systems. See the INFORMATION section starting on page 6-1 of this manual for more detailed information about the aftertreatment process and its components.

Diesel Particulate Filter (DPF) System
Diesel Particulate Filter
(DPF) System
Introduction
The DPF system consists of a Hydrocarbon (HC) Doser (may not applytoallengines),aDieselOxidation
3 Catalyst (DOC), and a DPF. The DPF filters soot out of the exhaust. When activated the HC Doser sprays a small amount of diesel fuel (the HC) into the exhaust. The catalyst in the DOC reacts with the HC to generate heat. The heat is used to clean (regenerate) the DPF by reducing the trapped soot to ash.
Controlling the
Regeneration Process
Your vehicle is equipped with either a two-position or three-position Regeneration Switch, mounted on the dash.
If equipped with a two-position Regeneration Switch, the driver can initiate a Parked Regeneration when certain operating conditions are suitable for regeneration, however, you will NOT be able to Stop a regeneration if the ATS has initiated one automatically. Refer to " Parked Regeneration on page 3-11 "
If your vehicle is equipped with a three-position Regeneration Switch, the driver can control the regeneration by overriding the ATS when certain operating conditions are not suitable for regeneration. Refer to " Stop an Automatic or Parked Regeneration on page 3-13 "
WARNING: If you operate in environments that contain explosive vapors or flammable materials, look to see if your vehicle’s Regeneration Switch is equipped with a STOP function. The STOP function must be activated prior to entering the above environment(s)
to prevent automatic engine regeneration from occurring, which could cause an explosion or fire. Failure to equip your vehicle with the proper switch (function) or failing to activate the STOP function before entering a combustible environment may cause an explosion or fire that could lead to death, personal injury, equipment or property damage.

Start
Depressing the button in the START direction for at least 4 - 8 seconds will initiate a parked regeneration.
Depressing the button in the START direction for at least 4 - 8 seconds will initiate a parked regeneration.

NOTE: During normal vehicle driving, the regeneration switch must be in the CENTER position.
CENTER is the normal position of the switch. Unless you are manually initiating a parked regeneration or intentionally stopping a regeneration,
