Navistar’s TranStar, manufactured by International Trucks, to be offered with ISL G engine

The Cummins Westport ISL G natural gas engine, manufactured by Cummins Westport Inc. (CWI), a major provider of high-performance, alternative fuel engines for the global market, will be offered by truck manufacturer Navistar in the International® TranStar and WorkStar trucks. The Cummins Westport ISL G, an 8.9 litre stoichiometric cooled-exhaust gas recirculation (EGR) engine, is certified to 2010 EPA emissions.
Westport says the ISL G is the #1 natural gas engine in North America, with over 13,000 engines produced since it was first introduced in 2007. While initial success was in the transit and refuse markets, more recently the conventional truck market has shown an interest in natural gas.

Roe East, President of Cummins Westport, commented, “Adding Navistar completes the listing of the ISL G with all major North American truck OEMs and reaffirms Cummins Westport’s position of market leadership for natural gas engines.”

The ISL G engine is a purpose built natural gas engine manufactured in the Cummins Engine Plant in Rocky Mount, NC that operates on either compressed natural gas (CNG) or liquefied natural gas (LNG), both of which are cost effective, low carbon, and low emissions fuels. With ratings up to 320 hp and 1,000 lb-ft of torque, the ISL G features maintenance free three way catalyst (TWC) aftertreatment, and does not require the use of selective catalytic reduction (SCR) or a diesel particulate filter (DPF).
