2024 Cummins QSK19 For Construction (Tier 3) QSK19 600

The QSK19 meets Tier 3 and Stage IIIA emissions standards, using in-cylinder technology, a simple and cost-effective solution that maintains the proven performance, dependability and durability while operating cleanly and efficiently.

The Tier 3 approved QSK19 is a powerful example of Cummins Quantum System technology at work. In the QSK19, state-of-the-art electronic controls and Cummins modular common-rail fuel system ensure clean, efficient performance and minimum maintenance. In the same compact footprint as its predecessor.

Available in a range of ratings from 506-700 hp (377-522 kW), the QSK19 offers an impressive range of standard features. And its fuel system is tolerant to a wide variety of worldwide fuels, including high-sulfur diesel and Japanese kerosene.

Features may include:

• Quieter, longer lasting and capable of handling high loads with ease.

• Lower intake air temperatures provide increased air density, resulting in more power and lower emissions from less fuel.

• Programmable electronic controls optimize combustion at all altitudes and conditions. Superior performance is driven by an upgraded CM850 ECM with twice the processing speed of its predecessor.

• Combination full-flow and bypass oil filter reduces maintenance costs as it extends service intervals.

• Precise liner machining with superior metal technology creates exceptional surface smoothness and durability.

• Proven single-piece ferrous cast ductile iron pistons for maximum durability and reliability. This advanced design also uses nitrided liners and cast-iron top rings to handle injection pressures with exceptional durability.

• Microfinishing makes it last twice as long as previous designs. Improved contact between the crosshead and rocker lever reduces wear and improves durability.

• Fleetguard's ES oil filter keeps your equipment on the job with a combination full-flow and bypass design that simplifies service and reduces replacement costs.
