QSL9 (Tier 4 Final/Stage IV)
Clearly Ahead. Cummins QSL9 Engine For Tier 4 Final/Stage IV.
For U.S. Environmental Protection Agency (EPA) Tier 4 Final and EU Stage IV near-zero emissions regulations taking effect in 2014, Cummins has a technology solution with clear advantages for every type of equipment.
While other manufacturers outsource their emissions aftertreatment systems, Cummins manufactures our own. This total integration of the engine and the exhaust system allows us to optimize fuel economy above the 5 percent we’ve already achieved with Tier 4 Interim engines, while achieving near-zero emissions at the same time.
QSL9 engines are rated at 250-400 hp (186-298 kW) for Tier 4 Final. It has the same heat rejection as the Tier 4 Interim engines, so there is minimal, if any, impact on the cooling package. The QSL9 combines very high strength with a compact footprint, for one of the best power-to-weight ratios in its class.
This engine is used in every type of construction equipment, including excavators, cranes, wheel loaders, compactors, air compressors and material-handling equipment such as heavy forklifts and container-handling trucks. It is commonly found in agricultural tractors and sprayers, as well as chippers and feller bunchers in the logging market.
All of the performance upgrades from Tier 4 Interim have been incorporated into the Tier 4 Final engines, and we’re maximizing torque output, reaching 1200 lb-ft (1627 N•m) for the QSL9.
