BorgWarner has introduced its next generation of cam torque actuators – intelligent cam torque actuation (iCTA) that delivers better fuel economy and reduced emissions.
iCTA provides fast cam phasing throughout the engine operating range, reducing emissions and improving fuel efficiency while maintaining optimal vehicle performance. “As global emissions regulations become more stringent, iCTA is an important advancement which enables manufacturers to tune engine calibrations for reduced emissions and improved fuel economy without sacrificing optimal performance,” said Joel Wiegert, Morse Systems president, BorgWarner.
“iCTA works with any engine architecture, and is an ideal solution for inline four-cylinder engines with low or varying cam torque energy. It’s a great addition to our industry-leading variable cam timing product portfolio.”
BorgWarner’s intelligent cam torque actuator allows the engine to be tuned for optimal opening and closing of the valves to maximise airflow when the engine needs it, and minimise it when it doesn’t.
iCTA enables this across a variety of engine types and is especially effective when applied to inline four-cylinder (I4) engine applications with varying cam torque energy. By recirculating oil within the actuator, iCTA reduces oil demand and engine parasitic losses over competing I4 solutions, resulting in increased fuel economy, lower emissions and improved vehicle performance.
This technology is expected to first appear on a variety of vehicles from two major vehicle manufacturers in China and North America in 2019 and 2020.
