“We are really pleased with the results,” said Lisa Farrell, director of Cummins’ Accelerated Technology Center. “As expected, the technology is showing a lot of promise, particularly for NOx reduction that will help (fleets) meet future NOx regulations.”
While netting up to a 20% uptick in fuel economy is impressive, dropping NOx is “really the driver, the emphasis of the technology,” Farrell said.
R. Scott Bailey, president and CEO of Tula, said the goal of NOx reduction has kept “a significant percentage” of the company busy “working on this technology over the last several years.”
Tula s diesel Dynamic Skip Fire technology provided impressive results in a Cummins X15 diesel engine. Tula Chief Engineer John Fuerst said dDSF can be used on light and medium-duty diesel engines. “We see a huge amount of opportunity down at the lower displacements,” he said.CumminsCummins and Tula began working on diesel cylinder deactivation in early 2019.
