Cummins demos cylinder deactivation tech for X15

摘要

The prospect of cylinder deactivation in diesel engines advanced last month as Cummins and propulsion software company Tula Technology announced a successful demonstration of diesel Dynamic Skip Fire (dDSF) in a Cummins Efficiency Series X15 engine. With cylinder deactivation, some cylinders get no fuel when full power isn't required. The technology is used by some automakers to help improve fuel economy and reduce emissions.
