Delphi Invests in Fuel-Saving Tula Technology

Revolutionary Dynamic Skip Fire technology provides significant fuel-efficiency improvement

SAN JOSE, Calif., July 30, 2015 — (PRNewswire) —   Tula Technology, Inc. is pleased to announce the completion of a new round of investment led by Delphi Automotive PLC, a leading global automotive supplier. The investment, which signifies another key industry endorsement of Tula's technology, will be used to advance the continued development and commercialization of the company's revolutionary, fuel-saving Dynamic Skip Fire (DSF) cylinder deactivation system.

"The significance of this new relationship goes beyond the investment itself," said R. Scott Bailey, president and CEO, Tula Technology. "Delphi's strong expertise in engine management systems and valvetrain components will help us to further optimize the overall performance of DSF and accelerate the deployment of our unique technology for three, four, six and eight-cylinder engines."

Tula's DSF technology is the industry's first individual cylinder deactivation system, delivering exceptional fuel efficiency while successfully managing engine noise, vibration and harshness (NVH). In independent tests, DSF has improved fuel efficiency by 17 percent as measured on a CAFE basis when compared to a vehicle that does not have cylinder deactivation.

"To meet the fuel efficiency demands of our customers, we are committed to investing in cutting-edge technologies that reduce emissions and improve fuel economy, and DSF software certainly fits the bill," said Jeff Owens, Delphi chief technology officer. "We look forward to working with Tula to support the ongoing development of this exciting technology."

Tula's revolutionary control approach integrates advanced digital signal processing, culled from consumer electronics technology, with sophisticated powertrain controls, to create the ultimate variable displacement engine. DSF technology does not rely on fixed cylinder deactivation or switching between fixed patterns. Rather, it continuously makes dynamic firing decisions on an individual cylinder basis to deliver the required engine torque for all vehicle speeds and loads while avoiding unwanted vibration. This approach delivers optimal fuel efficiency over a wide range of driving conditions, resulting in real-world improvements in fuel economy that drivers will appreciate.
