Cummins QSB and QSX series engines will shine in Paris

Cummins will demonstrate in Paris on construction machinery exhibition meet the United States and Africa highway Phase IV Final emission standards (EPA Tier 4 Final / EU Stage IV) QSB series of 6.7 liters and 15 liters QSX engine series are a new generation of ultra-clean Cummins In the treatment system , the particulate matter and nitrogen oxide emissions were reduced to 0.02 g/kWh and 0.4 g/kWh, respectively, and both items were reduced by 90% compared with the Tier 3 stage, and the power and fuel economy were further improved. While losing other performance advantages, it reached ultra-low emission standards that were nearly zero in 2014.

The QSX15 Tier 4 Final achieves 2,100 rpm at 503 kW (675 hp), a peak torque of 2,800 Nm, and an increase in power of 34 kW (45 hp). It can perform at its best under the most difficult operating conditions. Powerful and powerful, 525 Horsepower (392 kilowatts), 44 horsepower (33 kilowatts); fuel economy increased by 5% compared to Tier 4 Interim, and fuel efficiency will increase further by 3%-4% by 2014. QSX15 adopts Cummins particulate filter and selective catalytic reduction (CPF-SCR) combined ultra-cleaning post-treatment system to reduce emissions while increasing power; use Cummins Variable Cross Section Single Turbo Charger (VGTTM) to avoid Twin turbo complexity.
