What Is an EGR System?
The Exhaust Gas Recirculation (EGR) system reduces nitrogen oxide emissions by routing a portion of exhaust gas back into the engine. This lowers combustion temperatures and helps meet emissions standards.
What Are the Signs of a Clogged DPF?
Loss of power, excessive fuel consumption, frequent regens, and check engine lights are common signs of a DPF problem. If not addressed, a clogged DPF can lead to derates and complete shutdown.
