Like many filters on a diesel truck, the diesel particulate filter (DPF) requires periodic cleaning to function properly. In normal use, pollutants and soot can clog the DPF. Cleaning the DPF will ensure it continues to work properly, reducing harmful exhaust emissions, maintaining fuel efficiency, and preventing potential engine damage, Rislone explained in a press release. Modern diesel vehicles of all sizes are equipped with complex aftertreatment systems to reduce exhaust emissions. The DPF’s role in these systems is to capture and store soot particles.

California has agreed to formally repeal much of its controversial Advanced Clean Fleets electric-truck mandate as part of a legal settlement. Key provisions of ACF already were not being enforced because the state did not get a required waiver from the Environmental Protection Agency.

Among other things, a press release from the AG’s office explained, the ACF rule targeted any fleet that operated in California, regardless of where the fleet was headquartered. Given California’s large population and access to international ports, the news release said, this rule would have had nationwide effects on the supply chain. In the settlement, California agreed not to enforce the Advanced Clean Fleets rule and to start the process to repeal it. Click here to learn more.
