Exhaust & DPF Service

Your exhaust system contains more than just your muffler that serves to muffle the noise of the engine. It also has the job of redirecting hot exhaust gas from the engine and out through the tailpipe, as well as treat the exhaust in order to remove the harmful pollutants that are dangerous to breath in.

Sometimes exhaust leaks are loud and obvious, but other times it’s more of a “ticking” sounds when the engine is started, and then soon goes away as you drive. Sometimes there isn’t a noise to tell you there’s a problem. When the unusual noise doesn’t give the exhaust problem away, the telltale sign will be when you small the exhaust in your fleet vehicle, or visibly seeing exhaust coming from the engine compartment or under the vehicle.

Similar to how a catalytic converter controls emissions and pollutants, your diesel particulate filter (DPF) is in line with your exhaust pipe and is designed to capture soot particles emitted by your diesel engine. When is comes time to clean and service your fleet vehicle’s DPF there is a misconception that filter regeneration is the same action as cleaning it. This is not true. Filter regeneration is the process of combusting the soot particles inside the filter when back pressure has built up. Cleaning the DPF requires taking the filter out of the exhaust system and putting it in a special cleaning chamber.

When should my DPF be cleaned?

DPFs should be cleaned every 50,000 miles, or about once a year.
Your diesel particulate filter captures soot from the exhaust and ash from motor oil. A majority of the trapped particulates are burned off during the course of normal operations without the driver ever noticing the indicator light turning on in the instrument panel. Eventually a warning becomes persistent enough for the driver to notice and initiate a an active regeneration.

Ultimately, the ash in the filter’s honeycomb structure builds up and has to be serviced in order to be completely cleaned. We’ll remove you diesel particulate filter, clean it, and place it back on your fleet vehicle.
