B5.9 and 6.7 are the most popular diesel engines manufactured by Cummins. Now is its fourth decade of continuous improvement. Since 2019, the B series adopts an EGR-free design. Compared with the current model, the power has increased by 5% and the peak torque has increased by 31%. Cummins award-winning VGT™ Turbocharger sets the industry standard for reliability and durability as it increases equipment productivity. Increased fuel economy and longer maintenance intervals contribute to a reduced cost of operation and lower Total Cost of Ownership.
EGR-free architecture reduces complexity, improves reliability and reduces the cooling system space claim. Multiple component options allow for easier installation and maintenance. These include a choice of front- or rear-sump oil pan locations, on-engine or remote-mounted options for ECM and maintenance filters, the option of Rear Engine or Front Engine Power Take Offs, plus your choice of four turbocharger orientations; high-mount front and rear, or low-mount front and rear.
The Single Module™ aftertreatment system combines DPF, SCR and urea dosing in one unit which takes up 50 percent less space and weighs 30 percent less than the prior system.
