The first of the company’s next generation of ultra-high efficiency aftertreatment systems is designed to be upwards of 60 percent smaller and 40 percent lighter than the EPA 2013 solution it succeeds. EcoFit Single Module’s compact size also enables better heat management and retention for improved fuel economy capability, Cummins engineers note, while a simple single-pass exhaust flow design delivers low back pressure.
The flagship of the manufacture’s severe duty line of vocational trucks, the 122SD suits specialty/heavy-haul, cane and oversized loads, along with mixers and dumps. New options announced at the 2015 Work Truck Show in Indianapolis are best suited for severe terrain and off-road applications: oil pan skid plates; 12-in. frame rails; threaded front suspension spring pins and bushing; and, heavy-duty bolted cross-members. Factory-installed front-bumper mud flaps and fog lights with rock guards are also available.
Brake drum longevity is a perennial source of frustration and headaches for heavy-duty truck operators, company officials note. Like putting a pair of ballet slippers on an elephant, they add, standard-duty brake drums are no match for the extreme weight, aggressive pressure and frequent stops that define heavy-duty trucking.
