BorgWarner has detailed its supply of advanced wastegate turbocharging technology for numerous hybrid electric vehicles (HEVs) from BYD Auto Industry Company Limited.
The turbochargers are used on BYD Auto’s 1.5-liter direct injection gasoline engine in its Qin, Song and Yuan HEVs as well as the 2.0-liter direct injection gasoline engine in its Tang and Song HEVs.
BorgWarner states that its wastegate turbochargers are designed to meet challenging emissions requirements by offering ‘powerful yet efficient performance’. The locally produced turbocharging solutions provide solid torque characteristics over the entire engine speed range whilst also improving fuel economy for hybrid powertrains. In addition, BorgWarner also delivers its technology for numerous gasoline powered vehicles of BYD Auto.
“We are proud of being the supplier of choice for this fast-growing domestic automaker in China, extending the mutually rewarding collaboration by delivering our turbocharging technology for advanced hybrid powered vehicles,” said Frédéric Lissalde, president and general manager, BorgWarner Turbo Systems. “This cooperation enables BorgWarner to strengthen its market-leading position and allows us to further optimize our technology for plug-in hybrid vehicles. In turn, our wastegate turbochargers help BYD Auto to grow and comply with stringent emissions regulations.”
BorgWarner’s KP39 and K03 turbochargers are equipped with a water-cooled bearing housing to withstand high exhaust temperatures produced by gasoline engines. Due to its fast response and low inertia, the pneumatically actuated KP39 turbocharger is said to provide ‘powerful pick up from very low revs without sacrificing performance at high revs’ for improved drivability across a range of driving situations. The proven K03 turbocharger features an optimized wastegate to control boost and improve fuel economy.
