The Peterbilt Models 520 and 320 equipped with the Cummins ISL-G Near Zero engine have been granted eligibility for the California Air Resources Board (CARB) Hybrid and Zero-Emission Truck and Bus Voucher Incentive Project (HVIP).
HVIP encourages the commercialization of low-emitting hybrid and zero-emissions trucks by assisting fleets with the purchase of these advanced technology vehicles.
Peterbilt introduced the Cummins Westport ISL-G Near Zero NOx emissions natural gas engine in the Models 520 and 320 in 2016. NOx emissions in the ISL-G Near Zero engine emissions are 90 percent lower than the current EPA limit.
The ISL-G Near Zero engine emissions are 90% lower than the current EPA NOx limit through the introduction of a three-way catalyst in the after-treatment, advanced engine calibration, and a closed crankcase ventilation system (CCV).
The new engine’s performance and efficiency match the current ISL-G, with 320 hp and 1,000 lb.-ft. torque available. Industries that will most benefit from the new option include linehaul, vocational, and refuse applications.
Similar to the currently available ISL-G engine, the ISL-G Near Zero operates on 100% natural gas, which can be carried on the vehicle as either compressed natural gas (CNG) or liquefied natural gas (LNG). The new ISL-G Near Zero can also run on renewable natural gas (RNG).
“Peterbilt is a leader in environmentally-friendly solutions for the industry,” said Robert Woodall, Peterbilt Assistant General Manager of Sales and Marketing. “Eligibility for the HVIP voucher will allow customers participating in the program to benefit from the advanced technology and rugged durability of the Models 520 and 320."
The 2018 Models 520 and 320 will be eligible for HVIP when spec’d with the Cummins ISL-G Near Zero engine with a GVWR of 33,000 – 80,000 pounds.
