Peterbilt Motors Company has introduced the Cummins Westport ISL-G Near Zero NOx emissions natural gas engine for its Vocational Truck models 567, 520 and 320. The ISL-G Near Zero emissions engine will become available for production in Models 520 and 320 by year-end. The new engine will become available in the Model 567 in early 2017.

The ISL-G Near Zero engine emissions are 90 percent lower than the current EPA NOx limit through the introduction of a unique three way catalyst in the after-treatment, advanced engine calibration and a closed crankcase ventilation system (CCV).

Cummins Westport ISL G Near ZeroThe new engine’s performance and efficiency match the current ISL-G, with 320 horsepower and 1,000 lb-ft torque available. Customers with linehaul, vocational and refuse applications will benefit from the efficient option.

Like the currently available ISL-G engine, the ISL-G Near Zero operates on 100% natural gas, which can be carried on the vehicle in either compressed (CNG) or liquefied (LNG) form. The new ISL-G Near Zero can also run on renewable natural gas (RNG).
