Jack Roberts- Las Vegas- At the CONEXPO-CON/AGG show today in Las Vegas, Navistar senior vice president Jim Hebe showcased the company’s long-awaited 15-liter diesel engine. “Many of our competitors said we’d never get to this day,” Hebe noted in his opening remarks. “But we are here with a 15-liter, EGR-only solution for our customers in severe duty vocational applciations.”
Hebe noted that to fill the 15-liter gap in Navistar’s diesel engine line-up, the company essentially had four options: “We could have developed our own, which would have taken too long,” he explained. “We could turned to a European partner — but none were available. We could have gone to SCR, which was not in the best interest of our customers. Or we could find the best available engine technology available in North America in the Caterpillar C15 block and leverage that with our air, fuel turbo and electronic systems to give our customers the best solution for their severe duty needs — and that’s exactly what we did. This is Navistar engine technology and expertise built upon a proven Caterpillar platform.”
The new MaxxForce 15 diesel is available with up to 550 horsepower and 1,850 pound-feet of torque. Peak torque is reached at 1,000 rpm and holds steady to 1,600 rpm, according to Navistar. This reduced gear shifts in uphill terrain and allows for shifting at lower speeds when accelerating. The MaxxForce 15 will be built in Navistar’s Huntsville, AL, engine plant and is available now in vocational configurations. Engine options for on-highway (non-vocational) applications will be available in late summer.
In other news. Navistar announced a strategic partnership with Indiana Phoenix to produce a new, front-discharge Continental Mixer truck this fall. According to Steve Guillaume, general manager, Continental Mixers, the new front discharge mixer will complement the company;s line-up of integrated rear discharge mixers while integrating the components and engineering expertise of Navistar’s International truck brand. The mixer model will be sold and serviced through Continental Mixer dealers who will also provide parts support and unparalleled chassis service expertise. Production launch is expected for fall 2011.
Continental Mixers also announced an all-new lightweight integrated mixer which will utilize a proprietary high-strength steel specifically formulated for concrete mixers. This new design will deliver a nearly 2,000-pound weight savings versus comparably spec’d steel mixers. The new lightweight mixers include the optional ZF gearbox which integrates the hydraulic pump in the gearbox housing. In addition, multiple barrel sizes are available to meet customer requirements. The new lightweight mixer will be available on both International WorkStar and International PayStar chassis.
