Every QSK19 engine is a powerful example of Cummins Quantum System technology at work. Including self-diagnostics, prognostics and more. The QSK19 state-of-the-art electronic controls combined with a high-pressure injection system ensures clean, powerful and efficient operation every time. These powerful engines are designed to give every oil and gas application maximum performance with minimum maintenance.
Available in a range of ratings from 525 to 800 hp, these heavy-duty diesels meet Tier 2 emissions standards* without compromise. A low-maintenance two-stage oil filter is just one of the many features that minimize downtime. Cummins PowerMatch and Advisor are ready to provide expert assistance with your spec'ing and installation process.
Every QSK19 engine comes with a 2-year/2,000-hour base warranty, with 3-year/10,000-hour standard protection on major components.
* The next-generation QSK19 engine, available in January 2005, achieves Tier 3 engine emissions standards for the oil and gas market by incorporating new combustion technology and a common-rail fuel injection system. Tier 3 compliance for the QSK19 in additional markets will be announced in the near term.
Features & Benefits
Cummins QSK19 engines come with these standard features, so you get more power and economy out of every one of them.
- Extra-Wide Gear Train - Quieter, longer-lasting and capable of handling high loads of injector pressures with ease.
- Single-Stage HolsetTurbocharger - Lower intake air temperatures provide increased air density, resulting in more power and lower emissions.
- Large Fan Drive and Bearings - Increased fan size for improved cooling capacity.
- Full-Authority Electronic Controls - Programmable controls optimize combustion based on engine load and atmospheric conditions. Provides advanced monitoring, diagnostic, prognostic and reporting capabilities, with engine protection features.
- Two-Stage Oil Filter - Combination full-flow and bypass oil filter reduces maintenance costs as it extends service intervals.
- Longer-Lasting Intake and Exhaust Valves - Valve and seat are machined out of select materials for longer life. Rotators on both intake and exhaust ensure uniform wear.
- Precision-Honed Cylinder Liners - Precise liner machining with superior metal technology creates exceptional surface smoothness and durability.
- Articulated Steel Pistons - 30% longer life, increased reliability and improved combustion result from the two-piece piston design.
- High-Durability Camshaft - Microfinishing makes it last twice as long as previous designs. Improved contact between the crosshead and rocker lever reduces wear and improves durability.
