Cummins MidRange Engine Leadership

2013 ISB6.7_Fuel_3qtr_High - LargeAt Cummins, we know that leadership within a category happens only when you combine a robust initial design, years of experience and continuous improvement – as seen in our MidRange ISB6.7 engine platform.

The success story of Cummins MidRange engines began 33 years ago with the first B Series engine, built at the Rocky Mount Engine Plant in North Carolina. This engine platform represented a major leap for a company that was known primarily for heavy-duty diesels used in over-the-road (OTR) trucking applications. Customers immediately took notice, as these engines delivered the superior reliability and durability customers expected from Cummins, right from the start.

The combination of a heavy-duty engine design, higher compression ratios and a broad power range made the engines highly versatile and popular with OEMs and customers, but it was an ongoing and relentless quest for improvement that helped Cummins achieve significant market growth in the MidRange market. Advances included the introduction of the 24-valve cylinder head on the ISB in 1998, improved air handling and increased reliability with the VGT® Turbocharger, reduced maintenance with advanced NanoNet® fuel and air filters and the launch of full-authority electronic controls for improved fuel efficiency, performance and emissions compliance ahead of the mandatory timeline.

The results speak for themselves. To date, Cummins has produced over 12 million B Series engines, with a new one coming off the line every 18 seconds. The superior fuel economy of today’s ISB6.7 is enhanced by an air-intake throttle that utilizes Exhaust Gas Recirculation (EGR) and Selective Catalytic Reduction (SCR) more efficiently, for added mpg. Service intervals and durability are extended with the NanoNet fuel filter. The proven reliability of this platform has made it ideal as the base engine for Cummins Westport to convert for natural gas fuel with the ISB6.7 G currently in field test and entering production later in 2016.

Cummins has totally redefined expectations in the medium-duty truck market, delivering class-leading fuel economy and quality with the lowest cost of operation. The combination of proven experience, versatility and reliability is a big reason why Cummins ISB6.7 command over 80 percent market share in Class 6 and Class 7 commercial trucks. It’s a remarkable testimony to the passion and drive of Cummins engineers and the outstanding effort of our sales force and service teams, earning the loyalty and trust of your MidRange engine customers today – and for years to come.
