Every Result. Better. TM Tier 4 Interim/Stage IIIB Customer Field Tests

The Challenge. Meeting the emissions standards for EPA Tier 4 Interim and EU Stage IIIB in 2011 is a requirement for all engine manufacturers and has been the industry challenge. Cummins has achieved these very low emissions standards while creating better products, providing greater productivity, reliability and fit within the packaging requirements. Cummins has devoted significant engineering and technical resources, along with real-world customer testing, to validate our next-generation off-highway engines. Getting A Head Start.

Operating in the Alps, a snow groomer on a field test with a Tier 4 Interim/ Stage IIIB QSL9 engine performs more effectively at high altitude than the previous Tier 3/Stage IIIA engine.

Project Superintendent Barry Blankenship has this to say about the field test results: ■ Flawless Performance. “The machine has operated flawlessly as far as the engine is concerned. It picks up faster with better turnaround cycles and returns to full rpm quicker. And we’ve never had to stop the...

Drilling For Dollars. Stewart Brothers Drilling Company is a contractor that drills all types of wells all across the Western United States. They installed a Tier 4 QSL9 with the same 350-hp rating as their outgoing engine in a mobile mud pump/drill rig.

You notice that on climbing hills and drilling. We’ve noticed more lifting...

■ Better Performance Is No Shock. “We know the QSX15 engine is inherently strong.and we have proved that the Cummins Particulate Filter in the exhaust stream can also meet the highest shock load and vibration levels out in the field.” Every Question.
