What Is An EGR In A Truck?
An EGR system recirculates a portion of exhaust gases back into the engine to lower combustion temperatures and reduce emissions. This helps limit nitrogen oxide output while maintaining engine efficiency and meeting emissions standards.
How To Tell If A DPF Is Clogged?
A clogged DPF often causes warning lights, reduced engine power, poor fuel efficiency, and frequent regeneration cycles. In severe cases, the truck may enter derate mode or shut down to prevent further damage to the engine and exhaust system.
