Cummins, Navistar extend supply agreement

Diesel engine maker Cummins Inc. and Navistar International Corp. are extending their engine supply agreement for Class 8 on-highway diesel engines

Diesel engine maker Cummins Inc. and Navistar International Corp. are extending their engine supply agreement for Class 8 on-highway diesel engines through 2013 – a deal that provides for the ongoing supply of Cummins ISL, ISM and ISX engines for use in International brand Class 8 trucks.

“Navistar and Cummins have a strong partnership and history of collaboration in serving our mutual customers,” said Ed Pence, Cummins vp & gm for the company’s heavy-duty engine business. “We have been working closely with Navistar to integrate our 2010 solutions, and this agreement will deliver the right technology to meet customers’ needs for operational efficiency and low operating costs, with high performance and reliability.”

As part of the long-term agreement, beginning in 2010, Cummins will be Navistar’s exclusive supplier for 15- and 16-liter big bore diesel engines (Cummins ISX) for all of Navistar’s Class 8 trucks in North America. Also, as previously announced, Cummins plans to meet the 2010 EPA requirements for its heavy-duty engines without aftertreatment for oxides of nitrogen (NOx) – specifically, without using selective catalytic reduction (SCR) systems that will be employed by rivals Detroit Diesel Corp., AB Volvo, and Paccar.

Cummins is pursing a technology path similar to what Navistar is following for its diesel engines for 2010, using a high pressure common rail fuel system combined with next generation Cooled Exhaust Gas Recirculation (EGR), advanced electronic controls, air handling improvements plus a diesel particulate filter (DPF).

Cummins noted that its next-generation EGR technology will not add complexity to the vehicle while power, torque, fuel economy and maintenance intervals will remain the same as today’s engine models. The company added that its engines will be fully certified and compliant to the near-zero EPA 2010 emissions standards.
