Cummins Westport Announces New Heavy-Duty Natural Gas Engine

February 20, 2012

~ISX12 G Natural Gas Engine Targets Regional Trucking, Vocational and
Refuse Markets in North America~

VANCOUVER, Feb. 20, 2012 /PRNewswire/ – Cummins Westport Inc., announced today
the ISX12 G, a 12 litre heavy-duty, factory built dedicated natural gas
engine for regional haul truck / tractor, vocational and refuse
applications.  The new ISX12 G is currently in field trials with full
production expected to commence in early 2013.

The ISX12 G natural gas engine is based on the Cummins ISX12 diesel
engine platform, the newest member of Cummins heavy duty engine
family.  The ISX12 G will operate exclusively on natural gas (CNG or
LNG) utilizing Cummins Westport’s proprietary spark-ignited,
stoichiometric combustion with cooled exhaust gas recirculation (SEGR) 
technology, first introduced with the 8.9 litre ISL G.

The ISX12 G features three-way catalyst aftertreatment, which is
packaged as a muffler and is maintenance free.  No diesel particulate
filter or selective catalytic reduction aftertreatment will be
required.  Preliminary specifications include a range of ratings to 400
hp and 1,450 lb-ft torque, optional engine brake, and manual and
automatic transmission capability to meet customer and original
equipment manufacturer requirements.  The ISX12 G will be manufactured
in Cummins’ heavy-duty engine plant in Jamestown, New York.

“This is an important product development for Cummins Westport given the
increasing demand for natural gas vehicles in the heavy-duty market,”
said Roe East, President of Cummins Westport.  “The ISX12 G will offer
customers heavy-duty performance, reliability, and durability and a
choice of either compressed natural gas or liquefied natural gas as a
fuel.”

The ISX12 G target markets at launch are North American regional haul
and vocational truck/tractor, and refuse applications, where demand for
natural gas vehicles is growing.  Anticipated end-use applications in
the regional haul market segment include intermodal and distribution
operation, pickup and delivery.  Potential post-launch market
opportunities include motor coach and specialty vocational
applications.

The ISX12 G is expected to be certified at launch to meet the U.S.
Environmental Protection Agency and California Air Resources Board
emission standards of 0.20 g/bhp-hr NOx and 0.01 g/bhp-hr PM.  The
engine is additionally expected to be capable of meeting EURO VI and
pending U.S. greenhouse gas and fuel economy regulations.

Partial funding in support of the ISX12 G engine development has been
received from the U.S. Department of Energy’s National Renewable Energy
Laboratory (NREL) and the California Energy Commission in conjunction
with the Gas Technology Institute.
