Navistar's New N-Series Engines: Turbo-Driven & Emissions Ready

Navistar's new N-Series of diesel engines, the N-9, N-10 & N-13 all feature dual sequential turbochargers to offer powerful, smooth performance for any job, in any terrain, from stop light to mountaintop.  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.  Being equipped with Dual Fixed Geometry Turbochargers such as these means:  

  • Less moving parts and complexity for more reliable performance
  • Prevention of high bearing loads and overloads
  • Excellent throttle response

The N-Series engines all feature current, state-of-the-art, proven SCR technology such as used on Cummins engines, so each N-Series engine meets all existing emissions target requirements on their own merits without the need for or use of emission credits.

The N-Series' electro-hydraulic, high-pressure fuel system features new high-efficiency injector nozzles and advanced electronic control strategies for fuel economy gains.  Also offering wet-sleeve design and in-chassis rebuild capability, the N-Series offer a complete package of high performance, low maintenance and low cost of operation suitable for any application.

MaxxForce 7 Overview

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.
