Let’s run this scenario: A regen is needed as a truck is en route to its destination. You coordinate with your fleet manager, dispatch and your driver to schedule the needed regen. Everything has been communicated; you cross it off your to-do list and forget about it—until the truck rolls into one of your bays

Truck aftertreatment service data case study

Both the diesel particulate filter (DPF) and the diesel oxidation catalyst (DOC) are pricey components, but the costs can be compounded if the DOC is left unattended and pushes you to replace the DPF more often than you should be. During aftertreatment service, you’ll want to inspect the DOC and look for evidence of aging,

How heavy-duty truck aftertreatment components can impact each other

While the DPF and DOC are the components we typically associate with aftertreatment service issues, improperly maintained aftertreatment systems can lead to a host of other operational issues. “Issues with the emissions system can have a ‘knock-on’ effect on various components in the engine environment,” said Dr. Barry Southward, vice president of catalyst technology for
