Cummins Press Release  /  November 2, 2018

Cummins showcases its new structural engine in Italy for the first time at EIMA 2018. Displayed in Hall 15 on Stand A/5, visitors will see the Cummins Stage V B6.7 engine integrated into a structural driveline designed for agricultural tractor use.

Fabio Vaiani, Regional Sales Manager, Off-Highway at Cummins, said: “Cummins has been a successful supplier to the agriculture sector since 1919 when our first single cylinder engine was manufactured for farm pumps. However, it has been some years since we have had a structural engine in our power portfolio. Italy is an important market for our business, so EIMA is an ideal location to showcase the engine in the country for the first time.”

The structural capability has been designed into the B6.7 engine, the latest version of the renowned Cummins B Series engine.  With over 13 million B Series units sold around the world it is proven to deliver high availability in challenging duty cycles.  For Stage V it moves up to 326 hp (243 kW) with a peak torque of 1375 Nm - a 30 percent increase over that of Stage IV.  Cummins has the capability to tailor engine performance for farm work, with the power bulge and torque back up available ideal for agricultural tractor operation.

For Stage V, Cummins has integrated key in-house technologies into the engine to achieve the operational benefits.  The B6.7 uses proven variable-geometry turbocharger technology, with the single Holset VGT® achieving exceptional power density and responsiveness with fuel-efficient performance.  

The B6.7 uses Cummins latest Single ModuleTM aftertreatment technology, which is smaller and lighter than its predecessor at Stage IV.  The savings are up to 40% in envelope size and up to 20% in weight.  The higher NOx conversion efficiency enables the required level to be met without the use of EGR.  The system also removes 99.9% of all PM by weight and count.  For an agricultural tractor this technology will be adapted to suit the space requirements without impacting lines of visibility from the cab.

The Stage V engines including the B6.7 are designed as global platforms, with a shared installation for domestic and export business.  Manufacturers can have increased production flexibility, with common hook-up points wherever the equipment will be sold.  The exhaust aftertreatment would be the only key difference between specifications.
