EPA 2010 compliance without SCR or DPF is an option offered by Kenworth with the introduction of the Cummins Westport ISL G natural gas engine in T800 short-hood and W900S models. They’re aimed at vocational, municipal, and pickup-and-delivery applications.
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. Rated at 320 hp and 1000 lb ft of torque, the engine is EPA 2010-compliant with a maintenance-free, three-way catalyst and doesn’t need 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, says Kenworth.
The trucks in question are mated to Allison transmissions.
