Cummins ‘redefines a classic’ with its new B-Series engine

INDIANAPOLIS, Ind. – Cummins Inc. announced three new products at the Work Truck Show March 1, lead by the new 2017 B6.7 diesel engine, adding to the company’s longstanding line of B-Series engines.

Cummins also unveiled the B6.7’s sister engine, the 2017 L9, with ratings from 260 hp to 380 hp and 720 lb-ft to 1,250 lb-ft, and the 2017 Single-module Aftertreatment, which brings a notable reduction in size.

“Medium duty truck customers have made Cummins their engine manufacturer of choice due to the unparalleled uptime they have experienced with our B- and L-Series engines,” said Brett Merritt, executive director of on-highway business. “This is the legacy that Cummins has created over nearly a century of engine innovation and more than 30 years of B-Series and L-Series availability. And that’s why Cummins is redefining classics – by introducing the newest-generation B- and L-Series engines – the B6.7 and L9.”

The B6.7 engine offers a 200 hp-to-325 hp, 520 lb-ft-to-750 ratings range, up to 7% better fuel economy and stop-to-start capability.

Cummins launched its B-Series engine in 1984 and have produced over 11.2 million since the engine’s inception.

“It is the blue-jeans of the American trucking industry,” said Srikanth Padmanabhan, vice-president, engine business for Cummins, of the B-Series engine.

The Single-module Aftertreatment, which the company said was a customer-driven design, combines a diesel oxidation catalyst, a diesel particulate filter and selective catalytic reduction systems into a single canister.

Cummins said each of the new products would come with connected diagnostics, which would be able to send a report to the driver’s cellphone on the health of the engine, offering peace-of-mind and “the largest and most capable support network in North America.”

  • Other than the fact that these new engines were “unveiled” at the Work Truck Show you provided us with no details about what makes them “new”. Fuel system upgrade? New turbo? Less reciprocating mass? Reading this article left me feeling like I was served whipped potatoes for dinner but no meat and gravy.
