Natural Gas for Severe-Duty Rig

Freightliner model 114SD with natural gas

Freightliner Trucks has announced that the Cummins Westport ISX12 G heavy-duty natural gas engine will be available as a factory-installed option for the 114SD severe-duty truck model in 2015.

The 114SD/ISX12 G combination will be ideal for demanding jobs such as mixer, crane, and sewer vac. The 12-liter natural gas engine features ratings up to 400 hp and 1450 lb ft of torque, and operates on compressed natural gas (CNG) or liquefied natural gas (LNG). Factory-installed back-of-cab-mounted CNG tanks are available in 60 and 75 diesel-gallon-equivalent (DGE) configurations.

The 114SD has been available with natural gas with the 9-liter Cummins Westport ISL G engine since 2011.

Built on Freightliner’s severe-duty platform, the versatile 114SD features a chassis engineered for ease of body upfit and is available with a wide range of vocational rear suspensions and frame options up to 4.4 million RBM. A heavy-duty frame, steel-reinforced aluminum cab, and flexible specs make the 114SD ideal for the toughest jobs, the company says.

Since 2008, Freightliner Trucks has sold more 3500 natural gas-powered trucks and tractors.
