Navistar unveils new EGR engine at MATS
28 Commercial Carrier Journal April 2009 equipment in brief N avistar last month introduced a new 15-liter version of the MaxxForce engine for its International truck brand. The engine was developed using a proven formula of collaboration, said Eric Tech, presi-dent of Navistar's engine division. The company worked with Caterpillar in producing the MaxxForce 15, leveraging a proven platform, including the block, crankshaft, head and other components of the Caterpillar C15, he said. Navistar will add to that foundation the fuel and air systems it developed for the MaxxForce 11- and 13-liter engines. Caterpillar announced in June 2008 that it will exit the heavy-duty on-highway engine business effective with the next round of emissions cuts in January 2010. Tech said maximum ratings will include 500 hp with 1,850 lb-ft of torque as well as a 550 hp version at the same torque level. Both 1,800 and 2,000 rpm governed speeds will be offered. The engine will be assembled at Navistar's Huntsville, Ala., plant along with the MaxxForce 11- and 13-liter engines. The necessary testing, verification and certification for the MaxxForce 15 means it won't be available in January 2010. Five million miles of testing will be done before the engine is introduced, according to Tech. As a bridge, Navistar will use Cummins ISX engines built in 2009 to the extent allowed by the U.S. Environmental Protection Agency, said Tim Shick, director of business and prod-uct strategy for Navistar Engine Group. In addition, the MaxxForce 13 will be used for applications that don't require 15-liter power. Shick expects the 15-liter engine to be available in early 2011. Development of the MaxxForce 15 took several years, said Jim Hebe, senior vice president of North American sales operations. It's all about integration, and International wanted a more integrated engine strategy. Today, International is the most vertically integrated truck manufacturer. Referring to the fact that Navistar is the only engine maker not using selective catalytic reduction to meet the new emissions regulations that go into effect in January 2010, Hebe said: The competition says we're on an island. We think it's more like an oasis. Navistar will meet the 2010 regulations using a combination of enhanced exhaust gas recirculation and emissions credits. With the addition of the MaxxForce 15, the Navistar heavy-duty engine family ranges from 11 to 15 liters with power ratings from 300 to 550 hp. John Baxter The MaxxForce 15, expected to be available in early 2011, will combine the block, crank and head of the Caterpillar C15 with fuel and air management and other systems Navistar developed for the MaxxForce 11 and 13 heavy-duty diesel engines. Navistar unveils MaxxForce 15 15-liter engine will use Caterpillar C15 block, crank its 1.3 million-square-foot plant in Saltillo, northern Mexico which officially opened last month can build 30,000 heavy-duty trucks annually. The daily output of eight trucks was expected to increase to 12 to 15 a day this month. ability of the Cummins ISX Series engine as an option for the Cascadia 125-inch BBC product line. The truck maker also said it would be the first OEM to introduce Allison Transmission's new Load-Based Shift Scheduling transmis-sion feature on its Business Class M2 and other heavy-duty trucks. Volvo Trucks North America said that its trucks meeting U.S. Environmental Protection Agency 2010 emissions standards will have a $9,600 surcharge to help recoup the invest-ment in selective catalytic reduction and mandatory onboard diagnostics. The surcharge will apply to new trucks built with Volvo D11, D13 and D16 engines, as well as those with the Cummins ISX. Dodge says its new 2010 Ram 2500 and 3500, both available this fall, have been redesigned both inside and out. New styling cues have been taken directly from the Ram 1500 redesign, along with the heavy-duty models' dis-tinctive grill, hood and bumpers. Under the hood, Dodge says it has equipped the truck with the choice of a 6.7-liter Cummins Turbo Diesel engine rated at 350 hp and 650 lb-ft of torque, or a 5.7-liter gas HEMI V-8 rated at 383 hp. plans to assemble and market all-elec-tric zero-emissions commercial vehicles in North America. The company says it initially will focus on battery-electric-powered vehicles for depot-based route delivery fleets.
