Ever wondered what DPF regen is and how it works on your Paccar MX engine?

Let's break it down!

1. Active Regen: Your truck's exhaust system injects fuel to raise the temperature of the DPF filter, burning off soot actively. This typically happens when driving under heavy load.

2. Passive Regen: This occurs naturally when exhaust temperatures are high enough to burn off soot without additional fuel.

3. Forced Regen: Triggered manually when the truck is in high soot mode, often necessary when other regens fail.
