Exhaust System Repair

Our Heavy-Duty Truck Exhaust System Repair Services:

The exhaust system on your heavy-duty vehicle is responsible for a lot more than most think. Rather than just suppressing engine noise, your exhaust is also responsible for protecting drivers from exhaust fumes and preventing pollutants from reaching our atmosphere. How is this accomplished, you may ask? Well, using a series of tubes and emissions control components, your exhaust is filtered and funneled away from your passenger compartment. This protects both you and our atmosphere from harmful diesel emissions. If you’re looking for a heavy-duty repair shop that does excellent exhaust repair and maintenance, you’ve found one.

Getting To Know Your Exhaust Emissions Control Systems

Diesel Particulate Filter (DPF)

Every heavy-duty truck has a Diesel Particulate Filter (DPF). These filters are designed to capture soot and other diesel particulate matter before it exits the engine. Although they don’t require maintenance often, they do need to be cleaned every few years as their storage capacity is not infinite. Some have self cleaning modes, whereas others need to be cleaned by a mechanic. If you’re DPF needs to be cleaned, you’ll likely see an exhaust light pop up on your dash. If left for too long, your truck may go into limp mode.

SCR Catalyst and DOC

These two components are responsible for breaking down harmful pollutants into their most basic parts. Your SCR Catalyst breaks down nitrogen oxides, whereas your DOC breaks down carbon monoxide and hydrocarbons. Both your DOC and SCR Catalyst can get clogged after years of use and may have to be cleaned by a mechanic. Also, since these components sit quite low under your vehicle, you may even have to coat them with rust-prevention fluid every once in a while.
