On July 18, Volvo Trucks North America announced the availability of an engine that meets California Air Resources Board (CARB) 2024 Omnibus regulation requirements for low nitrogen oxide (NOx) and particulate matter (PM) emissions standards.
The CARB Omnibus regulation mandates a 75% reduction in NOx emissions and a 50% reduction in particulate matter (PM) from heavy-duty on-road engines for engine model years 2024 through 2026 compared to existing U.S. Environmental Protection Agency (EPA) standards.
Volvo Trucks’ CARB 24-compliant engine features an advanced emission control system integrated with a fully serviceable linear exhaust aftertreatment system (EATS).
Each component, including the Diesel Oxidation Catalyst (DOC), Diesel Particulate Filter (DPF), Aftertreatment Heater, and Selective Catalytic Reduction (SCR), is designed for individual servicing or replacement.
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.
The CARB 24-compliant engine is available for order now in the VNR and current VNL models with a power rating of 455 hp and 1650 lb-ft of torque.
