Jacobs and Tula Collaborate to Promote CDA and Dynamic Skip Fire to Help Clients' Products Compete

Jacobs and Tula plan to add Jacobs CDA and Tula diesel DSF technology to a Class 8 demonstrator vehicle to experience the innovations.

FREMONT, CA: Jacobs Vehicle Systems partners with Tula Technology to bring Jacobs Cylinder Deactivation (CDA) valve actuation technology and Tula's Dynamic Skip Fire (DSF) control algorithms together to promote more rapid development. The two firms have been working together on research and development for two years on emissions reduction for medium and heavy-duty trucks to fulfill better environmental rules that keep getting tighter.

The software for differentiating, zeroing, and quantifying the targets (DZQT) significantly benefits many laboratories and several leading manufacturers of metrology devices. Low-load cycle performance was modeled with a tool to help precisely capture the system's low-load operation. When this method was implemented, CO2 emissions fell by up to 5 percent, and NOX emissions dropped by more than 70 percent.

“Jacobs Vehicle Systems and Tula Technology are both great companies with great technologies, and we’ve been even more effective working together,” says 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.”

“While CDA and dDSF are available to commercial power train manufacturers as separate systems, our experience indicates that integrating the two technologies delivers much greater benefit to today’s medium- and heavy-duty engines,” says 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 NOX and CO2 simultaneously.”

The agreement will allow technical progress to increase the operational range of the two technologies to reduce emissions. Jacobs and Tula will also minimize NOX and CO2 emissions in off-road vehicles and outfit a Class 8 demonstrator truck with Jacobs CDA and Tula's diesel DSF technology.
