MaxxForce Engines For International Trucks in Michigan

With Navistar's International Truck Lineup,
You Enjoy A Wide Range Of Engine Options

International truck buyers have available to them not just a single engine, but a whole range of MaxxForce models, Cummins engine models, and the new N Series.  After a brief hiatus, Navistar has once again partnered with Cummins, reviving a 75 year history of mutual success, to offer the ISB 6.7 Liter and the ISX 15 Liter engines.  The medium duty DuraStar, for example, has three different MaxxForce engines that can be chosen in addition to the Cummins ISB.  International's ProStar+ can be purchased with the International N13 with SCR or the Cummins ISX 15 Liter, the combination of which was just named '2014 Truck Of The Year' in Heavy Duty by the ATD. 

Navistar will unroll new versions of its N Series and additional models that will be available with Cummins in the coming months.  Stay tuned for more exciting engine news!

Navistar's Heritage of Excellence In Engine Production
Navistar began building engines more than 110 years ago and began experimenting
with diesel engines in 1916.  It made its first diesel engine, the D-40, for use in International Harvester tractors in 1933 and its first diesel-powered truck in 1937. 
With this experience and Navistar's commitment to offering the industry's latest and
best technology, it's easy to understand why MaxxForce engines offer superior performance, reliability and fuel economy.  Click on the heading link above to view a more complete history of International's diesel engine production in pdf form.

Industry-Leading Technology In The Modern Era

All MaxxForce engines utilize the following technology, setting them far apart from
the competition:

  • Compacted Graphite Iron Block (CGI) brings increased durability and
    power without added weight, compared to typical gray iron.  Because CGI has
    at least 75% higher tensile strength, 45% higher stiffness and near double the fatigue strength of iron, MaxxForce engines offer both lighter weight and
    superior durability.  This platform handles the highest fuel pressures that
    deliver the best fuel combustion while reducing vibration and noise.
  • Advanced Air Managment featuring dual sequential turbochargers - the
    smaller, primary turbo responds quickly for immediate take-off at low engine speeds - the larger, secondary turbo provides peak power at higher speeds
    and  on steep grades. 
  • Advanced Fuel System featuring extremely efficient piezo injectors and high injection pressure for precise dosing, injection timing and optimal combustion
    which results in better fuel efficiency, in-cylinder emissions reduction, and
    super-quiet operation.
