Navistar announces 2010 pricing for Internationals
Aug 3, 2009 3:56 PM
Navistar has announced 2010-compliant MaxxForce Advanced EGR engine technology will increase International truck prices $6,000 to $8,000, depending on engine model.
Vehicles with mid-range diesel engines, including the MaxxForce 7, DT, 9, and 10, will increase by $6,000. Vehicles with heavy-duty diesel engines, including the MaxxForce 11 and 13, will increase by $8,000.
Increases will come in the form of a non-discountable surcharge applied to each vehicle’s base price.
To meet the 2010 EPA emissions requirements for diesel engines, International trucks will be powered by MaxxForce Advanced EGR (exhaust gas recirculation) engines with proven technologies including:
•Advancements in fuel injection: The next-generation fuel injection systems are capable of delivering fuel into the cylinder multiple times per cycle and at higher pressures. Utilization of one or more pre- and post-injections along with the main injection event means combustion can take place over a longer period and be more complete, resulting in less creation of nitrogen oxide emissions.
•Improved air intake management: The advanced EGR system uses dual turbochargers. The first, smaller turbocharger spins up immediately to provide boost at lower engine speeds, while the second, larger turbo provides maximum power at higher engine rpms. The company also placed an inter-stage cooler between the turbochargers to help reduce air temperature going into the cylinders and allow more air to be packed into the large second-stage turbo for maximum power at high engine speeds.
•Improved electronic calibration: Engine controllers previously used a pre-programmed lookup table to determine the fuel-air mixture to burn. Increases in computing power allow the engine controller to continuously calculate the optimum mix to achieve maximum power and efficiency in many different situations.
•Proprietary combustion technology: The redesigned combustion bowl combines with the higher fuel injection pressure to break the fuel up into a finer mist spread more evenly inside the cylinder, resulting in a more complete and cleaner burn.
