Cummins showed off an emissions reduction concept that promises drastic reductions to NOx and particulate matter emissions in future diesel engines.

The Cummins emissions control system technology was on display at the IAA Commercial Vehicles Show in Hannover, Germany and Cummins said that it could minimize emissions enough to meet Euro 7 emissions regulations in the European market.

The concept combines turbocharged air management with exhaust aftertreatment  as a single close-coupled system with a new rotary turbine control. The design makes use of Cummins latest air and thermal management advances and the company says it could covert almost all NOx emissions to clean gas as it interacts with the selective catalytic reduction unit.

“This innovative system allows further reduction in NOx and PM emissions, while simultaneously improving fuel efficiency,” said Tim Proctor, Cummins executive director of product management & market innovation.

Other innovative technologies under development by Cummins to reduce friction and parasitic losses will also continue to make the diesel engine even more productive and energy efficient. Additionally, the use of enhanced design tools and advanced materials such as composites will bring opportunities to reduce component weight while retaining strength, further enhancing vehicle productivity.”

The system also includes Cummins connected suite of wireless monitoring, reporting, calibrating and servicing applications to help boost vehicle uptime. It also features over-the-air trim and parameter calibration to allow fleet managers to customize power and speed settings to match business needs and driver behaviors, road conditions, and geographic coordinates.

The technology suite also uses powertrain automation to improve driver efficiency by up to 6%, according to the company. Features such as Predictive Cruise Control use vehicle GPS to see the road ahead and precisely adjust speed to upcoming terrain. SmartCoast places the driveline into neutral on downhill gradients using vehicle momentum to save fuel, while SmartTorque2 constantly calculates the exact torque needed for the truck payload to minimize downshifting.

“While Cummins has a vigorous electrification program underway, our other key message at IAA is that the diesel engine is not standing still,” said Proctor. “With our technical advancements, we see diesel remaining as the primary source of power in the commercial vehicle sector for the foreseeable future. Cummins is committed to ensuring the power of choice is available for our customer’s many different vehicle types, duty cycles and business requirements.”
