Cummins reveals natural gas engine

| February 24, 2012

Cummins Inc. announced a new on-highway natural gas engine with the Cummins Westport ISX12 G.

The ISX12 G is built on the Cummins ISX12 and uses the same base engine and key components as its diesel counterpart. It features Cummins Westport’s spark-ignited combustion technology with Stoichiometric cooled Exhaust Gas Recirculation, first introduced on the 8.9-liter ISL G.

The engine will feature Three-Way Catalyst after-treatment, which is packaged as a muffler and is maintenance-free.

Preliminary specifications include ratings up to 400 horsepower and 1450 lb./ft. of torque and an optional engine brake. The engine will run on either compressed or liquefied natural gas. It is expected to be certified at launch to meet EPA, CARB, Euro VI and pending U.S. greenhouse gas and fuel-efficiency standards and regulations. Production availability is scheduled for early 2013.
