About Our Exhaust System Repair Services for Trucks & Fleets

Aftertreatment Services

The diesel truck aftertreatment system is a crucial component of a diesel engine, responsible for reducing harmful emissions such as nitrogen oxides and particulate matter. It is made up of three main components:

(DOC) Diesel oxidation catalyst: Controls the internal temperature in the exhaust system in order to create ash from soot.
(DPF) Diesel particulate filter: This filter is responsible for trapping particulate matter.
(SCR) Select catalytic reduction systems: Reduces NOx through oxidation

Maintenance requirements for the aftertreatment system can vary based on the type of diesel engine, but typically include regular cleaning of the DPF, monitoring of exhaust gas temperature and pressure, and replacement of components as needed.

Our technicians use a specialized scan tool to confirm air measurements and proper temperature for diagnosing issues with the aftertreatment system. This allows our technicians to identify problems with the system.

DOC & SCR Catalyst

The DOC and SCR catalyst converts toxic emissions like carbon monoxide and NOx into their most basic forms, neutralizing them and reducing their negative impact on the environment. Over time, these parts may become blocked if an excessive amount of soot gets past the DPF. However, this would trigger a Check Engine or MIL dashboard warning light before becoming a significant issue. So, it’s crucial to have your truck serviced quickly when one of these warning lights appears.
