‘The Trucking Industry Is Facing Hard Choices,’ Says CEO:
New CWI Engine Combined with RNG Seen as Viable Answer

Southern California’s Total Transportation Services, Inc., is testing a low-NOx variant of the 11.9-liter ISX12 G engine from CWI/Cummins Westport, Inc., the California Natural Gas Vehicle Coalition reports. TTSI, Cal NGVC notes, is one of largest drayage trucking companies in the ports of Los Angeles and Long Beach. updated March 27


TTSI’s re-powered Freightliner Cascadia

The low-NOx ISX12 G is a field test unit, says a CWI spokesman. It has been installed in a Freightliner Cascadia tractor. It is fueled with LNG/liquefied natural gas. TTSI is using “Redeem” brand fuel, made with RNG/renewable natural gas supplied by Clean Energy Fuels, says a Clean Energy source.

Hauler at the Forefront

TTSI has long been an alternative fuel pioneer, committing to LNG/liquefied natural gas trucks for the ports nearly a decade ago (F&F, August 18, 2008) and later testing hydrogen fuel cell trucks for drayage operations (F&F, August 1, 2011).

According the company website, TTSI currently operates 57 LNG tractors.

As Clean as a Battery Truck?

Available for order later this year, the 11.9-liter engine is expected to be certified by the California Air Resources Board to produce 90% less NOx than the current EPA standard for heavy-duty engines – “equivalent,” says Cal NGVC, “to that of a truck powered by electricity from the electrical grid.”

“The trucking industry is facing hard choices on how we are going to reduce our emissions impact, especially here in Southern California,” TTSI president and CEO Vic La Rosa says in the association article.

‘Quickest and Most Affordable Way to Cut Our NOx’

“We believe the quickest and most affordable way to cut our NOx emissions to essentially zero is with the new CWI engine and renewable natural gas (RNG).

Cummins Westport’s 11.9-liter ISX12 G hit the market in 2012/2013 (F&F, December 19, 2012). Production of the low-NOx variant – the ISX12G Near Zero? – is to start early next year.

“We’ve successfully operated natural gas trucks in the San Pedro ports since the last Clean Trucks program in 2008, and it’s great that we now have a dramatically improved engine and an even cleaner fuel with renewable natural gas,” La Rosa said.

Next Year for the Low-NOx ISX12 G

Late last year Cummins Westport began full production of the low-NOx variant of its 8.9-liter engine, offering it as the ISL G Near Zero (F&F, October 18). Engines have been shipped to bus and refuse truck OEMs. The ISX12 G low-NOx engine is based on the 12-liter ISX12 G first introduced in 2012, Cal NGVC says. Production is to start early next year.

“CWI anticipates a large demand for this heavy-duty alternative-fuel truck engine,” the association says.

With Biomethane, It’s a Game-Changer

“We understand the importance of reducing NOx emissions, especially here in California and in the middle of one of the busiest transportation corridors in the nation,” said Cummins Westport president Rob Neitzke.

“This 12-liter engine, designed for heavy-duty trucks, can also reduce GHG methane emissions by 70% or more when run on renewable natural gas,” he said.

“We are also running field tests with other fleets in other applications,” a CWI spokesman told F&F, noting that production is to commence in the first quarter of 2018.

Learn More, Much More, at ACT Expo

Learn much more about the potential for low-NOx engine fueled by RNG at the special Game Changer Summit 2.0 session at ACT Expo 2017 in Long Beach, Calif. on Monday, May 1. CWI and TTSI chiefs Neitzke and La Rosa are among the scheduled speakers.

ACT Expo itself runs May 1-4 at the Long Beach Convention Center.
