Kenworth Adds Cummins Westport ISL G Natural Gas Engine to Product Line
22 December 2009
Kenworth Truck Company is expanding its product line with the introduction of the Cummins Westport ISL G natural gas engine for the Kenworth T800 short hood and W900S models. Now available for order, Kenworth's natural gas models are focused on vocational, municipal, and pickup and delivery applications.
Kenworth also offers T800 liquefied natural gas vehicles with the Westport GX engine and medium duty diesel-electric hybrids.
The Cummins Westport ISL G, an 8.9-liter stoichiometric cooled-exhaust gas recirculation (EGR) engine, meets 2010 EPA emissions, reduces greenhouse gas emissions compared to diesel, and offers top-level performance and efficiency. (Earlier post.) The ISL G engine operates on either compressed natural gas (CNG) or liquefied natural gas (LNG). With ratings up to 320 hp and 1,000 lb-ft of torque, the ISL G is 2010 compliant with a maintenance free three way catalyst (TWC) and does not require the use of selective catalytic reduction (SCR) or a diesel particulate filter (DPF). CNG and LNG fuel tanks can be configured to suit customer applications and range requirements.
"..does not require the use of selective catalytic reduction (SCR) or a diesel particulate filter (DPF)."
This is one of the advantages to NG only instead of NG and diesel. I could see these being used around docks where they haul the goods to warehouses. There are lots of ports trying to clean up the air and this is one way to do that.

"With ratings up to 320 hp and 1,000 lb-ft of torque" w/o diesel smells good..
