Cummins QSK19 Engine Overview
QSK19 FOR OIL AND GAS
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 QSK19 high-pressure injection system and electronic controls ensure clean, powerful and efficient operation every time. The ECM continuously monitors data from strategically placed sensors within the engine, optimizing the fuel-to-air mixture for maximum combustion. Fuel is injected at pressures exceeding 25,000 psi. This results in better utilization of fuel with fewer emissions. Getting more energy out of every drop of diesel fuel also results in greater power.
No matter what type of oil and gas job you have to do - the QSK19 is designed to work as an integral part of your equipment. Our electronic control module has the built-in capacity and connections to take input from all your other equipment or vehicle systems and adjust engine performance to match.
And everything that makes this a great engine for original equipment also makes it a great engine for repowers.
