Volvo Trucks North America has launched an engine that complies with the California Air Resources Board (CARB) 2024 Omnibus regulations that require a 75% reduction in nitrogen oxide emissions and a 50% reduction in particulate matter emissions for heavy-duty engines for the 2024-2026 model years, compared to existing U.S. Environmental Protection Agency (EPA) standards.

“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 at Volvo Trucks North America, in a news release.

The CARB 24-compliant engine features an advanced emission control system integrated with a fully serviceable linear exhaust aftertreatment system, Volvo claims.

Components like the diesel oxidation catalyst, diesel particulate filter, aftertreatment heater, and selective catalytic reduction are designed for individual servicing or replacement. This approach minimizes waste and maximizes operational lifespan. A 48-volt alternator has been added to the engine to supply power to a 48-volt battery that powers the heater during startup and low-load situations.

The engine, with a power rating of 455 HP and 1650 lb.ft. of torque, is now available for order in the VNR and current VNL models.
