This week, Volvo Trucks North America debuted a California Air Resources Board (CARB) compliant heavy-duty truck engine.
On July 18, Volvo announced the availability of the CARB 24-compliant engine in the VNR and current VNL models.
The new Volvo engine is designed to meet CARB’s Omnibus regulation requiring a 75% reduction in NOx emissions and a 50% reduction in particulate matter from heavy-duty on-road engines for engine model years 2024 through 2026 compared to existing U.S. Environmental Protection Agency standards.
“Volvo Trucks’ CARB 24-compliant engine features an advanced emission control system integrated with a fully serviceable linear exhaust aftertreatment system. Each component, including the Diesel Oxidation Catalyst, Diesel Particulate Filter, Aftertreatment Heater, and Selective Catalytic Reduction, is designed for individual servicing or replacement. This approach minimizes waste and maximizes operational lifespan. Additionally, a 48-volt alternator has been incorporated onto the engine to supply power to a 48-volt battery that powers the heater during startup and low-load situations,” Volvo said in a news release.
“To help our customers successfully navigate the complexities of the evolving regulatory landscape, Volvo has developed an engine that meets CARB’s new requirements. Volvo also offers information sessions to help our customers stay up-to-date and empower them to make informed decisions for their businesses,” said Johan Agebrand, director of product marketing, Volvo Trucks North America. “We continue to invest in new powertrain and vehicle technologies that support our sustainability agenda and our commitment to environmental stewardship. Volvo Trucks also continues to lead with the Class 8 Volvo VNR Electric truck and to invest heavily in the development of other zero and near-zero tailpipe emissions technologies.”
