Cummins Announces Near Zero Emissions Natural Gas Engine at 2017 Work Truck Show

Updates to B6.7 Diesel, Other Cummins Engines On Track for 2017

Mar 14, 2017
Cummins kicked off the first day of the 2017 Work Truck Show with a few announcements regarding its engine lineup, namely the new ISL G Near Zero natural gas powerplant and the newly refined B6.7 diesel offering.
Likely Cummins’ most common and legendary nameplate, the B6.7 receives a few noteworthy improvements for 2017, aimed at securing the engine’s status as the most fuel-efficient offering in its class. The B-Series I-6 now offers an average of 8.5 percent greater fuel efficiency and 5 percent better power compared to its predecessor, up from initial goals of 7 and 1 percent, respectively. “As the program progressed, we found opportunities to tune and optimize the engine, delivering further efficiency, and allowing us to surpass initial expectations,” said Jeff Caldwell, Executive Director of North American Truck OEMs.

Compounding the B6.7’s efficiency increases, Cummins offers the engine with automatic stop-start, reducing fuel consumption in high-idle applications. The stop-start feature, which is optional, helps bolster fuel efficiency by an average of 7 percent, and it also leads to reduced engine wear, improved oil life, lower DEF consumption, and better electrical system operation.

Cummins Westport, the company’s natural gas division, was next to deliver some exciting news in the way of its new near–zero-emissions offering. The so-called ISL G Near Zero beats stringent emissions standards by nine-tenths, with a greenhouse gas emissions rating of 0.02 grams per horsepower per hour. Cummins claims this engine is the first such midrange engine to receive a near-zero rating in greenhouse gas emissions, thanks to improvements over the regular ISL G that include closed crankcase ventilation, a slightly larger three-way catalyst, and software enhancements.

“We saw a perfect opportunity to fit the future needs of our customers,” said Rob Neitzke, president of Cummins Westport. Neitzke added the ISL G Near Zero was a way for Cummins to easily meet future clean-air standards without major infrastructure changes, such as would be required for other different fuels. Furthermore, he claimed the Near Zero’s net greenhouse gas effect goes negative when powered by natural gas derived from waste and food sources.

Cummins Westport also introduced the new ISB6.7G, a natural gas engine for medium-duty applications that’s based on the proven B-Series engine architecture. The 6.7G features a greenhouse gas emissions rating of 0.1 grams per horsepower per hour, and Cummins plans a Near Zero version of this engine for the future.

At the Cummins press conference at the 2017 Work Truck Show, Caldwell said, “Innovation is not limited to the brand-new.” Referring to the company’s continuous refinements to its current products, Caldwell called Cummins a technology company as much as an engine company. Given the impressive lab performance of its newest engines, we’d say he’s not far off.
