EPA07 Engines
rv dm 10.03.002
The EPA07 ATS varies according to engine manufacturer and vehicle
configuration, but the exhaust muffler is replaced by an aftertreatment
device (ATD). Inside the ATD, the exhaust first passes over the diesel
oxidation catalyst (DOC), then passes through the diesel particulate
filter (DPF), which traps soot particles. The soot is burned to ash
during a process called regeneration (regen).
