BorgWarner has partnered with GAC Motor to introduce its next generation of variable cam timing actuators – intelligent cam torque actuation (iCTA) – to GAC’s combustion and some models with hybrid applications. As emission standards becomes stricter, Chinese auto manufacturers are seeking more efficient and tunable intake and exhaust technologies to meet future emission regulations. A great addition to BorgWarner’s variable cam timing (VCT) technology, iCTA blends the best attributes of cam torque actuation (CTA) and torsional assist (TA) phaser technologies for better efficiency and improved fuel economy, offering automakers the opportunity to meet challenging State VI emission standards.
iCTA is a device that varies engine cam timing at a fast actuation rate with low oscillation. It will first be installed on GAC’s new compact SUV, the GS3. GAC began mass-producing engines with this BorgWarner technology in June 2019.
“We are glad to extend our long-term cooperation with GAC Motor,” said Brady Ericson, president and general manager, BorgWarner Morse Systems. “Our new iCTA technology is suitable for both combustion and hybrid applications, which are gaining increasing popularity. iCTA can operate across a variety of engine types, enriching BorgWarner’s industry-leading variable cam timing product portfolio. We developed this latest innovation and conducted a wide range of tests in order to meet our customers’ needs.”
This product is now manufactured in the BorgWarner Ningbo, China plant.
