The Cummins QSX combines an advanced dual overhead cam design with proven Cummins heavy-duty components. The result is dependable performance without compromise, every hour of every day.

The dual overhead cam design allows the engineers at Cummins to optimize combustion efficiency and the integrated engine brake (Intebrake™) at the same time, using advanced “in-cylinder” technology. And the advanced design not only meets Tier 3 emissions standards, it is the base platform to reach Tier 4 requirements as well.

Performance

The high-pressure injection system and electronic controls of the QSX ensure clean, powerful and efficient operation every time. Fuel is injected at pressures of up to 30,000 psi, for cleaner, more complete combustion. The intelligence of the electronic control system allows you to use a variety of fuel – even kerosene when diesel fuel isn’t available.

Add to that our patented wastegated turbocharger and you have an engine capable of delivering optimum performance at every rpm. The wastegated turbo maximizes output without overboost at high speed and improves airflow at lower speeds for improved responsiveness.

Versatility

No matter what type of job you have to do – from agriculture to mining to construction to a wide range of industrial applications – the QSX is designed to work as an integral part of your equipment. Our Electronic Control Module (ECM) has the built-in capacity and connections to take input from all your other 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.
