Don’t count diesel out.
Cummins announced a concept diesel emissions system today at the IAA Commercial Vehicles Show in Hannover, Germany which the company says will increase fuel efficiency and reduce emissions to levels previously thought impractical.
The concept emissions control system now under development by Cummins, combines the turbocharged air management with the exhaust aftertreatment as a single close-coupled system, together with a new rotary turbine control (RTC).
This new design fully utilizes Cummins latest advances in air and thermal management to immediately convert almost all NOx emissions to clean gas as it interacts with the selective catalytic reduction (SCR) unit. The large NOx and particulate matter reductions may invite a possible next level of Euro VII regulations anticipated during the coming decade.
“While Cummins has a vigorous electrification program underway, our other key message at IAA is that the diesel engine is not standing still,” said Tim Proctor, Cummins executive director of product management & market innovation. “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 customers’ many different vehicle types, duty cycles and business requirements.”
Other technologies under development at Cummins strive to reduce friction and parasitic losses in diesel engines.
“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,” Proctor added.
