Mining Tier 4 Final Engines to Be Certified

Cummins unveiled ultra-clean mining engines designed to meet European Union (EU) Stage V emissions regulations. The engines will be certified to U.S. Environmental Protection Agency (EPA)/ Air Resources Board (ARB) Tier 4 Final standards. The integration of Cummins’ latest aftertreatment system, the Single Module, with leading combustion and air-handling technology, allows the 2019 F3.8, B4.5, B6.7 and L9 engines to be exhaust gas recirculation-free. The Single Module system combines a diesel particulate filter, selective catalytic reduction and urea-dosing technologies in one unit, providing up to a 50% reduction in envelope size and a 30% reduction in weight compared with earlier products.

Separately, the company reported its Tier 4 Final engines, available from 49 horsepower (hp) to 675 hp (37-503 kilowatts [kW]), are operational in more than 600 installations. The company’s customer base reportedly includes more than 300 original equipment manufacturers. Cummins Tier 4 Final QSF2.8 engines are available for compact equipment from 49 hp to 74 hp (37-55 kW). The QSF3.8 power unit is a predesigned unit, including the cooling system, aftertreatment and diesel exhaust fluid tank, providing power from 100 hp to 130 hp (75-97 kW). The class-leading QSB6.7 engine provides power from 146 hp to 310 hp (109-231 kW), and the heavy-duty QSX15 engine is available from 450 hp to 665 hp (336-496 kW).
