Peterbilt Tackles Diesel Engine Regulations with New CARB-Certified Engines
Summary
Jason Morgan, Content Director at Fleet Equipment, explores the evolving diesel engine emissions regulations in his article. He discusses California’s strict rules, such as the Omnibus Low NOx standards and the Advanced Clean Truck (ACT) mandate, which have already caused a 50% drop in truck sales. These regulations aim to reduce nitrogen oxide (NOx) emissions and promote zero-emission vehicles. By 2027, the EPA’s GHG Phase 3 rules will extend these changes nationwide.
Peterbilt is adapting to these regulations by preparing to offer a CARB-certified diesel engine, the PACCAR MX-13, which features several upgrades to meet stricter emissions standards.
Peterbilt Tackles Diesel Engine Regulations with New CARB-Certified Engines
Diesel engine emissions – a hot topic in today’s climate
In his article, Jason Morgan, Content Director at Fleet Equipment, dives into the rapidly changing landscape of diesel engine regulations and zero-emissions trucking. He highlights Peterbilt’s response to the tightening emissions standards, particularly California’s strict rules like the Omnibus Low NOx standards and the Advanced Clean Truck (ACT) mandate. These regulations, aimed at reducing nitrogen oxide (NOx) emissions and promoting zero-emissions vehicles, have already caused a 50% reduction in truck sales in California. However, these changes won’t be confined to California for long. By 2027, the EPA’s GHG Phase 3 regulations will take effect nationwide, impacting all new truck sales across the U.S.
At a recent Peterbilt dealer event, Bobby Sanders, Peterbilt’s vocational sales manager, emphasized how these new diesel engine regulations will have a profound impact on the trucking industry in the next few years. Peterbilt is preparing for these shifts by offering cutting-edge solutions. Ben Whitaker, Peterbilt’s vocational marketing manager, detailed Peterbilt’s plan to be the first Original Equipment Manufacturer (OEM) to offer a CARB-certified diesel engine. The PACCAR MX-13 engine, designed for vocational applications, is at the forefront of this effort.
Peterbilt’s CARB-compliant MX-13 engine comes with several key upgrades. It features a new 48-volt generator mounted on the flywheel, a larger Selective Catalytic Reduction (SCR) system, and improved injectors—all designed to help meet stricter NOx reduction targets. Additionally, Peterbilt has made it easier to service the engine with enhancements like a clear fuel filter cap and DPF pressure sensor.
Peterbilt remains committed to navigating the evolving diesel engine regulations while continuing to meet industry demand. By staying ahead of emissions mandates, Peterbilt is positioning itself as a leader in delivering reliable, efficient diesel engines for vocational and fleet applications.
