Tech: New Technology Reduces Diesel Emissions

by

Tula Technology’s dDSF may take the already quite clean (especially compared with engines of just a little more than a decade ago) heavy-duty diesel engines to a level that reduces smog-producing emissions while increasing fuel economy and yet not losing any performance. The technology study was announced last month by Cummins, the largest heavy-duty engine manufacturer, and Tula, a technology innovator in Silicon Valley that has become a supplier to OEMs.

News: Cummins and Tula Work Together To Advance Diesel Tech

by

Cummins, one of the world’s leading diesel engine maker, has joined forces with Tula Technology, a California start-up, to explore a sophisticated cylinder deactivation system that could solve the conundrum. If it’s proven, the result would be a diesel engine that could reach a near-zero emissions level.

Tula has developed software algorithms that do something engineers in Detroit, Tokyo and Stuttgart had not thought possible—to shut off different cylinders independently, giving the engine power as needed in a given situation, but saving fuel by giving it only the power needed and not firing any extras cylinders.
