B6.7 For School Bus (2017)

SmartEfficiency: High-Achieve and Cost-Lowering

The Cummins SmartEfficiency initiative is a focused approach that improves uptime and reliability while providing a broad spectrum of reliable engine choices to meet every need. The combination of a low cost of operation, high reliability, clean operation and long-term durability are unsurpassed in the industry. The fact that all Cummins engines use the same control system technology and can be serviced at any authorized Cummins location ensures serviceability anywhere, anytime

Even with a legacy of over 12 million B series engines sold over the last 32 years, we continue to keep improving a time-tested and proven reliable product. That’s why Cummins is redefining a classic and introducing the newest-generation B Series engine – the B6.7. The Cummins B6.7 for 2017 is more efficient, with up to 7 percent better fuel economy over the EPA 2013 ISB6.7.  The B6.7 will have accumulated 1.5 million test miles in multiple real-world applications prior to its 2017 launch, ensuring exceptional uptime from the start. Plus, the 2017 B6.7 will be fully capable for the introduction of stop-start technology that will yield further improvements in fuel economy in stop-and-go duty cycles. That’s Cummins, SmartEfficiency – not just for the B6.7, but for an entire industry.

Aftertreatment Technology: Simply Better

The Cummins B6.7 diesel engine features a new Single Module™ aftertreatment system that sets the new standard for efficiency. It combines Selective Catalytic Reduction (SCR) and a Diesel Particulate Filter (DPF) into a single flow-through design. It occupies up to 70 percent less space and weighs up to 30 percent less. The smaller size allows it to be installed closer to the engine, for better heat management. That, together with the reduced weight, contributes to improved fuel economy. The UL2 Urea Dosing System eliminates the need for engine coolant lines to the doser, provides more efficient atomization, to minimize the risk of urea dosing deposits and reduces regeneration events, while maintaining a 3 percent to 4 percent Diesel Exhaust Fluid (DEF) usage factor.

Connected Diagnostics: Smarter Route Management with Connected Diagnostics

School bus drivers have enough to pay attention to without being concerned about engine fault codes. In the rare event that one is triggered while the bus is in operation, it can be diagnosed immediately over the air, through the addition of Connected Diagnostics. Cummins Connected Diagnostics delivers real-time engine fault code analysis, with a probable diagnosis and a recommended action for school buses that are equipped with telematics.
