International Truck and Engine Corp., a Navistar Co., announced its lineup of MaxxForce International diesel power engines for 2008 model year trucks, and provided specifications and technical details.
Beginning in January, MaxxForce engines become the signature powerplant for International brand on-highway Class 4-8 commercial vehicles. In North America, the MaxxForce product line ranges from the upgraded 4.5-liter V-6 MaxxForce 5 to the new MaxxForce 13 big-bore Class 8 engine. Another major highlight is the all-new 6.4-liter MaxxForce 7.
MaxxForce-branded engines are designed to deliver power, performance, reliability and durability while providing new lower emissions that contribute to a cleaner environment, the company said.
MaxxForce engines stand for performance – reinforcing International’s commitment to high-quality trucks and engines – and are backed by the largest commercial-truck dealer network in North America with more than 900 dealer locations and 7,000 service technicians.
For 2008 model year trucks, the MaxxForce engine lineup includes:
• MaxxForce 5, built on International’s V-6 engine platform, features an upgraded intake throttle, a larger EGR cooler and enhanced electronics. It will power Class 4-5 International CityStar commercial trucks with 200 horsepower and 440 ft.-lbs of torque.
• MaxxForce 7, International’s new V-8 turbo, provides increased performance and responsiveness, fuel economy improvements and quietness uncharacteristic of most commercial diesel engines. The MaxxForce 7 engine will power Class 5-7 International DuraStar series medium-duty trucks, IC brand buses, International brand commercial buses and two vehicles in the International XT Family. MaxxForce 7 offers ratings of 200-230 HP and 560-620 ft.-lbs. of torque. A 300-plus horsepower rating of the MaxxForce 7 will be offered in the fall 2007.
• MaxxForce DT is built on the DT 466 Inline 6-cylinder platform and is designed to provide reliability, durability, optimal fuel economy, improved serviceability and lower cost of operation to owners and operators, the company said. MaxxForce DT will power Class 6-8 DuraStar and WorkStar trucks with 210-300 HP and 520-860 ft.-lbs. of torque.
• MaxxForce 9, built on International’s I-6 architecture, features a bigger EGR system, foam-molded wiring harnesses and closed-crankcase ventilation system, which provide increased reliability and durability, the company said. The MaxxForce 9 powers Class 7-8 DuraStar and WorkStar commercial trucks with 300-330 HP and 800-950 ft.-lbs. of torque.
• MaxxForce 10, also built on the I-6 architecture, features a larger EGR system, foam-molded wiring harness and closed-crankcase ventilation system to provide increased reliability and durability, the company said. MaxxForce 10 powers Class 8 WorkStar and TranStar trucks with 310-350 HP and 1,050-1,150 ft.-lbs. of torque.
• MaxxForce 11 and MaxxForce 13 are International’s new big-bore diesel engines for the Class 8 truck market. These engines take advantage of recent technological advances to offer drivers a strong compacted-graphite iron cylinder block without added weight, outstanding fuel economy, excellent power characteristics and quiet, low noise, vibration and harshness, the company said. The MaxxForce 11 will be offered in TranStar, while the MaxxForce 13 will be available in the ProStar. More technical specifications will be announced in 2007, leading up to the production launch in the fall of 2007.
None of the enabling technologies being used to meet 2007 EPA emissions standards are new to International. It demonstrated 2007 EPA emissions levels for particulate matter seven years ago with its Green Diesel Technology particulate filters, and now has years of field experience with Green Diesel Technology and Ultra-Low-Sulfur-Diesel. International said it has had EGR technology for NOx emissions control in production for more than four years and has also had closed-crankcase ventilation systems on its diesel engines to comply with Class 2-3 GVW standards for several years.
