Both Truck Powertrain Solutions Help Meet Global Emissions Standards

Jacobs Vehicle Systems and Tula Technology have signed a cooperation agreement to accelerate the development of Jacobs Cylinder Deactivation^® (CDA^®) valve actuation technology in conjunction with Tula’s Dynamic Skip Fire (DSF^®) control algorithms. The agreement builds on two years of research and development collaboration between the two companies to reduce nitrous oxide (NO_X) and carbon dioxide (CO₂) emissions from medium and heavy-duty vehicles, helping to meet ever-tightening environmental regulations.

“Jacobs Vehicle Systems and Tula Technology are both great companies with great technologies, and we’ve been even more effective working together,” said John Fuerst, senior vice president of technology and innovation at Tula. “This agreement will advance our capabilities to produce better CDA products and dDSF controls.”

Independent laboratory testing has demonstrated that Jacobs CDA hardware and Tula’s dDSF achieve greater emission reductions when combined. Low-load cycle performance was estimated with a well-calibrated powertrain simulation tool to accurately capture the low-load system operation and emissions. This system showed as much as a 5% decrease in CO₂ and a 74% reduction in NO_X emissions compared to the baseline technology.

“While CDA and dDSF are available to commercial powertrain manufacturers as separate systems, our experience indicates that integrating the two technologies delivers much greater benefit to today’s medium- and heavy-duty engines,” said Steve Ernest, vice president of engineering and business development at Jacobs Vehicle Systems. “We have been working with Tula for several years, and this formal agreement solidifies our relationship as we demonstrate the benefits of using CDA and dDSF in tandem. Our efforts will provide the marketplace with sought-after solutions to meet increasingly challenging emissions standards. The synergies created through multiple development projects will offer customers the best possible outcomes for reducing NO_X and CO₂ simultaneously.”

The agreement will allow technical development to expand the operating range at which emissions reductions can be achieved when the two technologies are combined. Jacobs and Tula also will explore opportunities for reduced NO_X and CO₂ emissions in off-road vehicles and equip a Class 8 demonstrator truck with both Jacobs’ CDA and Tula’s diesel DSF technologies for customers to experience firsthand.
