In late April, Navistar International Corporation will begin delivering initial production models of the International ProStar equipped with MaxxForce 13 with SCR engines. The MaxxForce 13 features Cummins Emission Solutions aftertreatment and newly improved turbochargers, EGR valves, high and low temperature coolers and exhaust bellows. Electronic control modules have been recalibrated for the SCR systems as well.
Options for the MaxxForce 13 range from 365 to 475 with 1,250-1,700 lb/ft of torque. The remaining lineup of International heavy-duty truck models will transition to SCR engines in a phased launch throughout the year.
