Cummins Westport Begins Production of ISL G Near Zero Natural Gas Engine

North America’s First Commercially Available Near Zero NOx MidRange Engine

published: October 13, 2016

Cummins Westport Inc. (CWI) today announced that orders are being processed and production of the ISL G Near Zero (NZ) NOx natural gas engine has commenced. 

The ISL G NZ is the first MidRange engine in North America to receive emission certification from both U.S. Environmental Protection Agency (EPA) and Air Resources Board (ARB) in California to meet the optional 0.02 g/bhp-hr. Near Zero NOx Emissions standards eight years in advance of the 2023 California Near Zero NOx schedule and contributing to California Clean Air initiatives.

Exhaust emissions of the ISL G NZ are 90% lower than the current EPA and ARB NOx limit of 0.2 g/bhp-hr. and also meet the 2017 EPA greenhouse gas (GHG) emission requirements.  CWI natural gas engines have met the 2010 EPA standard for particulate matter (0.01 g/bhp-hr.) since 2001.

“The start of production of the ISL G Near Zero natural gas engine offers a game-changing solution for the reduction of urban tailpipe and engine related emissions,” said Rob Neitzke, President of Cummins Westport.  “Combined with the reliability and operating improvements on the base ISL G engine, the ISL G Near Zero is now at the forefront of cost-effective and dependable emission reduction strategies in transit, medium-duty truck and refuse applications.”

The ISL G NZ can operate on compressed, liquid, or renewable natural gas (RNG).  Operating ISL G NZ engines on RNG offers a significant GHG emissions benefit compared to fossil fuels. In addition to the dramatic reduction in NOx, the ISL G NZ will feature Closed Crankcase Ventilation, reducing engine related GHG methane emissions by 70%.

Leveraging the technology improvements of the ISL G, the ISL G NZ offers customers the benefit of improved reliability and durability as well as range and performance with the lowest emissions, utilizing maintenance-free Three-Way Catalyst (TWC) aftertreatment. TWCs are effective, simple, passive devices, packaged as part of the muffler.  Cummins Westport natural gas engines do not require active aftertreatment such as a Diesel Particulate Filter or Selective Catalytic Reduction. 

The ISL G NZ is manufactured at the Cummins Engine Plant in Rocky Mount, North Carolina.  Backed by a Cummins Factory Warranty and supported by Cummins Service Network, the ISL G NZ offers low emission performance and efficiency with engine ratings from 250-320 horsepower, and 660-1,000 lb-ft torque available.  For the convenience of customers, base warranty, extended coverage options, maintenance procedures, and service intervals are the same as the current ISL G.

The ISL G NZ engine is available as a first fit engine with transit, shuttle and school bus, refuse and truck original equipment manufacturers (OEMs), or as an engine replacement (repower) for existing  ISL G vehicles.   

CWI would like to acknowledge engine development funding support from South Coast Air Quality Management District, SoCalGas, and the California Energy Commission.
