Kenworth T800 short hood and W900S models to get Cummins Wesport ISL G natural gas engine
Kenworth Truck Company is expanding its product line in North America 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. Cummins Westport Inc. (CWI) is a provider of high-performance, alternative fuel engines for the global market.
In 2009, Kenworth became the first truck manufacturer to receive the Environmental Protection Agency’s Clean Air Excellence award in recognition of its environmentally friendly products.
Roe East, President of Cummins Westport, added, “Kenworth adding CWI engines to several models reaffirms our position in market leadership for natural gas engines. Kenworth now offers customers clean, economic natural gas power for a variety of truck applications.”
The Cummins Westport ISL G, an 8.9 litre stoichiometric cooled-exhaust gas recirculation (EGR) engine, meets 2010 EPA emissions, reduces greenhouse gas emissions, and according to CWI and Kenworth, offers top-level performance and efficiency. The ISL G engine 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 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.
