Cummins used IAA Hanover to “represent the next leap forward in diesel engine evolution” by displaying a concept of how a Euro 7 engine and after-treatment system could look.
While Euro 7 is not even at a formal proposal stage, Cummins is keen to demonstrate that environmental gains are to be had from diesel, to make it cleaner and more fuel efficient.
The display showed a concept (pictured) “capable of minimising emissions to levels previously thought unfeasible, including a possible next level of Euro 7 regulations anticipated during the coming decade,” says Cummins.
“The innovations will achieve a low nitrogen oxides (NOx) emissions future and deliver a reduction in the carbon footprint,” says Cummins.
Other 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.” It also promises lower component weight.
Says Tim Proctor, Cummins Executive Director of Product Management & Market Innovation: “While Cummins has a vigorous electrification programme underway, our other key message is that the diesel engine is not standing still.
“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.”
The concept emissions control system, combines turbocharged air management with exhaust after-treatment as a single close-coupled system, with a new rotary turbine control.
This new design uses 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.
