QSK19The company has enhanced the QSK19 engine to meet Tier 3 emissions within the 510- to 700-hp range. For applications meeting Tier 2 requirements, the engine is available up to 800 horsepower. Modular common-rail fuel system and in-cylinder advanced combustion technology help reduce NOx emissions levels by almost 40 percent—without after-treatment or other hardware. The 19-liter engine maintains the same basic footprint as the existing engine for minimal installation impact.
