Jacobs Vehicle Systems, based in Bloomfield, Connecticut, and Tula Technology Inc of San Jose, California, have announced a cooperation agreement aimed at accelerating the development of Jacobs’ CDA cylinder deactivation technology in conjunction with Tula’s diesel Dynamic Skip Fire (dDSF) control algorithms.

Results of the previously announced collaborative study on the effectiveness of Tula’s diesel Dynamic Skip Fire control software – an advanced cylinder deactivation control system - in reducing nitrogen oxides (NOx) and carbon dioxide (CO2) emissions on a Cummins X15 HD Efficiency Series diesel engine have been released at the Society of Automotive Engineers World Congress that took place in April in Detroit, by Cummins Inc of Columbus, Indiana and Tula Technology Inc, a specialist in propulsion efficiency, based in San Jose, California.
