Freightliner Trucks to offer Cummins Westport LNG engine

LNG Industry,


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

The ISX12 G engine is a larger-displacement natural gas engine, suitable for a variety of heavy-duty vehicles, including regional-haul trucks/tractors, as well as in vocational and refuse applications.

With a displacement of 11.9 litres and up to 400 hp and 1450 lb-ft of torque, the ISX12 G is the natural choice when considering alternative fuel for demanding applications. The engine operates on 100% natural gas, in either CNG or LNG form.

Featuring the same Stoichiometric cooled Exhaust Gas Recirculation (SEGR) combustion technology, spark ignition and simple Three-Way Catalyst (TWC) after-treatment as the Cummins Westport ISL G engine, the ISX12 G delivers strong pulling power and heavy-duty durability and performance that customers can depend on.

For best reliability and durability, the recommended maximum GVW for line-haul applications is 80,000 lb (36,287 kg). Recommended gearing is 1400 rpm to 1500 rpm at cruise speed, to optimise fuel economy.

The ISX12 G meets 2014 US Environmental Protection Agency (EPA) and California Air Resource Board (ARB) emission standards as well as the 2014 EPA and US Department of Transportation fuel economy and greenhouse gases regulations.

“The 114SD, when paired with the Cummins Westport ISX12 G heavy-duty natural gas engine, will provide our vocational customers with another green option for their toughest jobs,” said Mary Aufdemberg, director of product marketing for Freightliner Trucks. “Our entire natural gas product line – from the 114SD to the M2 112 and Cascadia 113 – is not only environmentally-friendly, but durable, productive and powerful.”
