Capacity Trucks selected Volvo Penta to supply EPA Tier 4 Final engines to power its Sabre series of terminal trucks. Texas-based Capacity supplies trucks for ports, warehouses, and intermodal terminals, and the Sabre line (developed with parent company REV Group) reportedly will set new standards for "durability, efficiency, productivity and lifetime costs of ownership."
Volvo Penta manufactures diesel and gasoline engines for marine and industrial power, 10 to 900 hp.
The U.S. Environmental Protection Agency’s emerging emission standards for off-road diesel engines cover excavators and construction equipment, tractors and other agricultural equipment, heavy forklifts, airport ground service equipment, and utility equipment such as generators, pumps, and compressors. The agency aims to reduce emissions by over 90% by integrating engine and fuel controls, including emission control technologies like the selective catalytic reduction (SCR) process, similar to what is expected for highway trucks and buses.
The EPA standard also sets standards for in-use diesel fuel, to decrease sulfur levels by more than 99%.
Volvo Penta’s Tier 4F diesel engines use a SCR process with cooled exhaust gas recirculation (EGR) to meet the EPA standards. The developer noted these engines do not require periodic regeneration, which reduces downtime and maintenance costs.
