Truck News  /  January 4, 2018

Cummins Westport’s 2018 ISX12N natural gas engine has been certified by the U.S. Environment Protection Agency (EPA) and the California Air Resources Board (CARB).

The ISX12N meets CARB’s optional low NOx standard of 0.02 g/bhp-hr, a 90% reduction from engines operating at the current EPA NOx limit of 0.2 g/bhp-hr.

The Cummins Westport natural gas offering is the first Class 8 truck engine for larger heavy-duty vehicles to certify to the 0.02 g/bhp-hr optional standard and provides the trucking industry a near-zero emissions solution.

“Cummins Westport’s 2018 product line offers customers ultra-low emissions with reliable performance,” said Bart van Aerle, president of Cummins Westport. “The ISX12N near-zero emissions natural gas engine provides truck and bus customers with an industry-leading alternative fuel option for demanding applications.”

With production starting February 2018, the ISX12N natural gas engine will be available with ratings from 320hp to 400hp and up to 1,450 lbs.-ft. of torque. The engine is designed for line haul, regional haul, refuse, vocational trucks, motorcoach, and commuter buses.

All Cummins Westport engines offer the option of using compressed natural gas, liquefied natural gas, or renewable natural gas as a fuel source.

EPA, CARB Certify Cummins Westport ISX12N Natural Gas Engine

Heavy Duty Trucking (HDT)  /  January 9, 2018

Cummins Westport announced that the Environmental Protection Agency and California Air Resources Board have certified the 2018 ISX12N natural gas engine.

The ISX12N was certified to meet CARB’s optional low NOx standard of 0.02 g/bhp-hr, a 90% reduction from engines operating at the current EPA NOx limit of 0.2 g/bhp-hr, according to CWI. The ISX12N also meets 2017 EPA greenhouse gas emission requirements.

Based on the ISX12 G, first introduced in 2013, the ISX12N natural gas engine will be available with ratings from 320 to 400 horsepower and up to 1,450 lb-ft. of peak torque. The ISX12N is designed for line haul, regional haul, refuse, and vocational trucks, as well as motorcoach and commuter buses.

Like Cummins Westport’s new L9N and B6.7N engines, the ISX12N will feature a new engine control module with improved durability, on-board diagnostics, an enhanced, maintenance-free three-way catalyst, and a closed crankcase ventilation system, according to the company.

All CWI engines offer customers the choice of using compressed natural gas, liquefied natural gas, or renewable natural gas as a fuel. RNG is pipeline-quality natural gas produced from the decomposition of organic waste, which can come from a variety of sources such as dairy farms, landfills, and urban waste treatment plants. Combining Cummins Westport’s ultra-low emission engines with RNG fuel provides additional GHG reductions, according to CWI.

“Cummins Westport’s 2018 product line offers customers ultra low emissions with reliable performance,” said Bart van Aerle, president of Cummins Westport. “The ISX12N near-zero emissions natural gas engine provides truck and bus customers with an industry-leading alternative fuel option for demanding applications.”

Production will begin in February of 2018.

Cummins Westport ISX12N Engine Tested for Performance

Heavy Duty Trucking (HDT)  /  October 3, 2018

An independent, third-party study on the Cummins Westport ISX12N 400 hp natural gas engine recently demonstrated that the engine meets and exceeds California Air Resources Board’s (CARB) optional Low NOx standard of 0.02 g/bhp-hr.

The study was carried out by The University of California, Riverside College of Engineering Center for Environmental Research and Technology, with funding provided by the South Coast Air Quality Management District, the California Energy Commission, and Southern California Gas Co. It confirms that natural gas engine technology provides one of the cleanest available options for on-highway transportation, according to Cummins.

Engine testing was performed on a chassis dynamometer, with test cycles representative of operation in California’s South Coast Air Basin. Results showed that the ISX12N 400 hp engine met and exceeded the target NOx emissions throughout a range of duty cycles.

When the engine operates on renewable natural gas, there are significant reductions in greenhouse gas emissions. In addition to providing air quality and greenhouse gas benefits, the ISX12N can also take advantage of low natural gas prices and available incentive funds.

In production since February 2018, the ISX12N was the first Class 8 truck engine for larger heavy-duty vehicles to certify to CARB’s optional Low NOx standard. Currently, more than 1,000 ISX12N engines have been produced for North American customers. 

The ISX12N is produced at the Cummins Jamestown, N.Y., engine plant, and is available from a wide variety of vehicle manufacturers. It’s designed for regional haul, refuse, and vocational trucks, as well as motorcoach and commuter buses. Cummins Westport natural gas engines can operate on compressed natural gas, liquefied natural gas, or renewable natural gas.
