Natural gas for Mack refuse vehicles

Posted: October 27, 2017

NIAGARA FALLS, ON – Mack LR and TerraPro refuse vehicles are now available with the Cummins Westport L9N natural gas engine, offering an option for those looking to generate near-zero levels of NOx.

The spark-ignited L9N can run on Compressed Natural Gas (CNG), Liquefied Natural Gas (LNG), or Renewable Natural Gas (RNG), and generates 320 horsepower and 1,000 lb-ft of torque. It also produces NOx emissions 90% lower than the U.S. Environmental Protection Agency’s limit of 0.2 g/bhp-hr, and meets 2017 limits for Greenhouse Gases.

The take rates for natural gas have been relatively flat in the context of low oil prices, but there’s still an interest in the fuel, said Curtis Dorwart, Mack refuse product manager. “The refuse industry has made a lot of investment in infrastructure for natural gas.”

“Within one organization, they’ll deploy gas as well as diesel. It all depends on what makes sense for them,” he added.

The LR model still comes standard with Mack’s proprietary 11-liter MP7 diesel, which delivers 355 horsepower and 1,260 lb-ft of torque. The TerraPro is also available with Mack MP7 and MP8 engines.
