The ISL-G Near Zero Engine Emissions are 90% 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).
“Peterbilt is producing increasingly efficient products,” said Scott Newhouse, Peterbilt Chief Engineer. “The addition of the ISL-G Near Zero emissions engine strengthens Peterbilt as an environmental leader.”
The new engine’s performance and efficiency match the current ISL-G, with 320 horsepower and 1,000 lb-ft tongue available. Customer with line haul, vocational and refuse applications will benefit from the efficient option.
“Peterbilt continues to lead the industry with the highest performing trucks on the road.” Said Robert Woodal, Peterbilt Assistant General Manager of Sales and Marketing. “We’re please to offer the ISL-G Near Zero engine as an excellent choice for our customers.”
Like the currently available 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)
The Cummins 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 567 in early 2017.
