Peterbilt opts for Cummins/Westport gas engine

Peterbilt Motors has decided to introduce the Cummins Westport ISL-G Near Zero NOx emissions natural gas engine for line-haul, vocational and refuse applications. Launch ismset for the year-end and early 2017.
It is claimed the ISL-G Near Zero engine offers emissions that are “90 per cent lower” than the current EPA NOx limit. The engines achieve this through the introduction of a “unique three-way catalyst” in the after-treatment, as well as “advanced engine calibration” and a “closed crankcase ventilation system” (CCV).
Because of the “90 per cent lower” the companies feel justified in using the term “Near Zero”.
“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 bhp and 1,000 lbft torque available. Customers purchasing Models 567, 520 and 320, that is 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,” claims Robert Woodall, Peterbilt assistant general manager of sales and marketing. “We’re pleased to offer the ISL-G Near Zero engine as an excellent choice for our customers.”
Like the currently available ISL-G engine, the ISL-G Near Zero operates on 100 per cent 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 Model 567 in early 2017Cummins Westport Inc. designs, engineers, and markets 6- to 12-litre spark-ignited automotive natural gas engines for commercial transportation applications such as truck and buses. The dedicated 100% natural gas engines are manufactured by Cummins and available as a factory-direct option from leading truck and bus manufacturers (OEMs).
Over 70,000 Cummins Westport engines are in service worldwide. Designed to meet the most stringent emissions regulations, they provide efficient and reliable service.
Cummins-Westport Inc. natural gas engines are certified with catalyst. They meet or exceed the toughest emissions standards including: U.S. Environmental Protection Agency (EPA), California Air Resources Board (CARB) and EURO emissions standards.
Westport corporate headquarters and engine test laboratories are located in Vancouver, British Columbia, Canada. The facilities feature nine engine test cells. In 1999, Cummins Inc. of Columbus, Indiana and Westport entered into a memorandum of understanding to explore development of HPDI technology for Cummins 15-litre ISX engine..
