Work with ESI Is ‘Suspended,’ ESI Enters Chapter 11

Navistar International is now focusing on spark-ignition engines from Cummins Westport, Inc. for its natural gas vehicles, the first of which is to hit the market early in 2013, the truck manufacturer says.

Navistar International is promising a dedicated-CNG version of its International TranStar drayage, beverage and regional haul truck for early 2013.

It’s bad news for Emission Solutions, Inc., which developed a spark-ignition variant of the popular Navistar DT 466 engine more than seven years ago (F&F, August 15, 2005), and had since become part of the larger company’s NGV commercialization plans (F&F, February 13).

ESI filed an involuntary Chapter 11 petition with the Texas Eastern Bankruptcy Court in mid-September.

“Navistar has suspended its production of natural gas-powered International DuraStar and WorkStar models with DT-466 engines converted by Emissions Solutions, Inc.,” says a Navistar spokesman.

‘We Remain Committed’

International’s new LoadStar severe service LCOE truck is to be available with the natural gas-fueled ISL G in mid-2013 (diesel version shown here).

Navistar will begin selling a dedicated-natural gas version of its International TranStar drayage, beverage and regional haul truck with CWI’s 8.9-liter ISL G in early 2013, he told F&F. It’s to be followed by the new International LoadStar severe service LCOE (low cab over engine) truck, also with the ISL-G engine.

Also according to the Navistar International spokesman, the company is planning to offer its Class 8 ProStar over-the-road tractor with the new 11.9-liter ISX12 G from Cummins Westport either late next year or early in 2014.

“We remain committed to natural gas,” the spokesman says. “We’re still optimistic on natural gas being a commercially viable transportation fuel.”

No Word Yet on Clean Air Power

He declined to say whether Navistar International’s suspension of work with ESI was related to Navistar’s late decision to go with SCR (selective catalytic reduction) to bring its mainline diesel products into compliance with 2010 U.S. EPA standards.

In addition to the Chapter 11 filing, ESI appears to have closed its doors, at least for now. Its McKinney, Texas headquarters telephone goes unanswered and chairman and CEO Jim Lapicola has declined to comment.

The Navistar International spokesman says his company has yet to make a decision on continuation of its work with UK- and San Diego-based Clean Air Power for larger, dual-fuel natural engines.
