Navistar announced Tuesday plans to roll its Selective Catalytic Reduction (SCR) efforts to the company’s medium duty line.
Navistar says, effective immediately, the Cummins ISB 6.7-liter engine will be available in International DuraStar medium-duty trucks and IC Bus CE Series school buses.
“The ISB will complement our existing engine offerings and will be a catalyst as we look to improve our medium-duty truck and bus business in 2014 and beyond,” Jack Allen, Navistar executive vice president and chief operating officer, told our sister site, Hard Working Trucks.
Navistar says it will continue to offer EGR-only versions of its mid-range engines utilizing its medium-duty emissions credits, adding the company has no plans to implement a proprietary SCR engine.
