Cummins Inc. - QSL9 Diesel Engines

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 after-treatment 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.
