Navistar to use Cummins emissions technology

US truck and engine manufacturer Navistar has entered into a non-binding memorandum of understanding with Cummins Engine Solutions under which Cummins will supply their urea based after-treatment (commonly referred to as Selective Catalytic Reduction) to Navistar for use with the new generation ICT+ truck engines.

Navistar expects that by combining the Cummins after treatment with its existing MaxxForce engines it will meet the 2010 US Environmental Protection Agency (EPA) emissions regulations and position the company to meet greenhouse gas (GHG) rules in advance of 2014 and 2017 requirements.

Navistar will continue to develop its in cylinder technology (ICT) for emissions reductions but will adopt the Cummins SCR system in the interim in order to bring forward the introduction of the new engines.

The current heavy-duty engines do not meet the EPA regulations and Navistar has had to use emission credits and pay non-conformance penalties for some of its truck models sold in the USA.

As part of the expanded relationship with Cummins, Navistar plans to offer the Cummins ISX15 engine in certain models of its on-highway trucks beginning in January 2013 and to begin the introduction of the ICT+ in its MaxxForce 13 litre engine in early 2013.

“With this clean engine solution we are taking the best of both technology paths to provide our customers with the cleanest and most fuel efficient engines and trucks on the market and to meet stringent US emission regulations,” said Daniel C. Ustian, President, Chairman and CERO of Navistar Inc.

Navistar manufactures the International brand of trucks and sells them mainly in USA, Canada, Mexico and Brazil. Also, it provides the cab/chassis for the Australian “CAT” branded trucks which are fitted with Caterpillar engines for the local market.

The current MaxxForce 13 engine develops 410 to 500 horsepower, while the larger MaxxForce15 is available in 435-550 horsepower ratings.
