International Debuts New Family of MaxxForce(TM) Diesel Engines

MaxxForce(TM) Diesel Engine Family from International
International Truck and Engine Corporation, a Navistar Company, unveiled the MaxxForce(TM) International Diesel Power engine lineup for trucks along with technical details.
Beginning in January, Class 4-8 commercial trucks with the International® name will be powered by MaxxForce engines. The enhanced 4.5-liter V-6 MaxxForce 5 and the MaxxForce 13 big-bore Class 8 engine are both part of the MaxxForce product line in North America. 6.4-liter MaxxForce 7, this function, is another noteworthy aspect.
"We offer a family of products that fulfills the needs of a wide variety of commercial truck applications," says Jack Allen, president of International Engine Group. The engines bearing the MaxxForce trademark are designed to deliver the customers' desired levels of power, performance, dependability, and reduced emissions that contribute to environmental cleanup.
According to Allen, "Always Performing" perfectly captures the MaxxForce brand. The MaxxForce brand unambiguously expresses our dedication to giving our customers the best-performing diesel backed by the best-performing personnel.
MaxxForce engines are supported by the largest commercial truck dealer network in North America, which includes more than 900 dealer locations and 7,000 service personnel. This demonstrates International's dedication to producing high-quality trucks and engines.
The array of MaxxForce engines is now accessible.
The MaxxForce engine lineup consists of the following:
- The MaxxForce 5 sports upgraded electronics, a larger EGR cooler, and a reworked intake throttle. It is built on the International V-6 engine platform. Class 4-5 International® CityStar(TM) commercial trucks will be powered by 200 horsepower and 440 lb-ft of torque.
The MaxxForce 7 V-8 turbo from International offers increased fuel efficiency, greater performance, and responsiveness, as well as a level of silence unheard of in most commercial diesel engines. Two International XT Family vehicles, IC brand buses, International brand commercial buses, Class 5-7 DuraStar(TM) series medium-duty trucks, and International® DuraStar(TM) buses will all be powered by the MaxxForce 7 engine. The MaxxForce 7 is rated at 200-230 horsepower and 560-620 ft.-lbs of torque.
Based on the illustrious DT 466 Inline 6-cylinder architecture, the MaxxForce DT provides owners and operators with dependability, longevity, greater fuel efficiency, enhanced serviceability, and lower operating costs. MaxxForce DT-powered Class 6-8 DuraStar(TM) and WorkStar(TM) trucks will offer 210–300 hp and 520–860 ft.-lbs of torque.
With its larger EGR system, foam-molded wiring harnesses, and closed-crankcase ventilation system, MaxxForce 9, which is based on International's ground-breaking I-6 architecture, offers improved dependability and lifespan. The MaxxForce 9's 300-330 hp and 800-950 ft.-lbs of torque power Class 7-8 DuraStar and WorkStar commercial trucks.
MaxxForce 10, which is likewise based on the I-6 architecture, includes a larger EGR system, a foam-molded wiring harness, and a closed-crankcase ventilation system to increase dependability and longevity. MaxxForce 10 provides Class 8 WorkStar and TranStar vehicles with 310–350 horsepower and 1,050–1,150 ft.-lbs of torque.
The MaxxForce 11 and MaxxForce 13 are two big-bore diesel engines from International for the Class 8 truck market. These engines provide drivers a strong compacted-graphite iron cylinder block that doesn't add weight, outstanding fuel efficiency, good power characteristics, and quiet operation with little noise, vibration, or harshness. The MaxxForce 11 is exclusively available in TranStar, whereas the MaxxForce 13 is available in ProStar.
Reliability of Emissions
There is nothing particularly innovative about the supporting technology that International is using to comply with the EPA emissions requirements. It showed EPA emissions criteria for particulate matter with its Green Diesel Technology particle filters seven years ago, and it now has years of field experience with both Green Diesel Technology and Ultra-Low-Sulfur-Diesel. In order to meet with Class 2-3 GVW regulations, International has also had closed-crankcase ventilation systems on its diesel engines for a number of years. Additionally, EGR technology for NOx emissions management has been in production for more than 4 years.
The MaxxForce engines powering commercial vehicles in North America have the tried-and-true engine technologies and cutting-edge aftertreatment systems necessary to deliver uncompromised performance while conforming to stringent U.S. EPA emissions requirements for diesel engines.
By focusing on three main goals—providing clean air with improved performance, never compromising reliability or durability, and maintaining the fuel-economy advantage of diesel—it continues to be the leader in the production of almost emission-free engines and trucks as well as a leader in the diesel industry's efforts to improve the quality of the air in the nation.
