Cummins ISX12 G ready for launch

Jeff Crissey March 20, 2013

In the natural gas market, Cummins received EPA certification last week on the long-awaited ISX12 G natural gas engine, which will enter limited production in April, with full production beginning in August.

“We expect volumes to ramp up quickly, and believe that this engine is a game changer when it comes to accelerating the move by a large number of customers to natural gas power,” says Jeff Jones, vice president of Cummins North American Engine Business, adding the company expects sales of the Cummins-Westport ISL G mid-range natural gas engine to eclipse 5,000 units in 2013.

Engine braking, as well as automatic and manual transmission compatibility, will be available. Both the ISX12 G and the ISL G utilize Cummins Westport’s proprietary spark-ignited combustion technology with Stoichiometric cooled Exhaust Gas Recirculation (SEGR) and a maintenance-free Three-Way Catalyst (TWC), and fuel can be stored on the vehicle in compressed natural gas, liquefied natural gas or biomethane forms.

All major truck OEMs will offer the ISX12 G in their model lineups.
