Westport introduced its newest line of natural gas products, an onboard liquefied natural gas (LNG) tank, Wednesday at the ACT Expo in Washington, D.C.

The company says its iCE PACK LNG Tank System is an onboard LNG system customized for spark-ignited engines.

The launch of the Cummins Westport ISX12G engine has moved spark-ignited engines into the regional haul segment, making LNG more suitable as a fuel. Westport says the iCE PACK provides increased range, longer hold times and faster fueling times.
