BorgWarner supplies turbocharging technology for Hyundai’s new 1.6-liter turbocharged gasoline direct injection (T-GDI) engine.

Available in the U.S. for the Veloster Turbo passenger car, the turbocharged engine features a maximum output of 150 kW (204 HP), an increase of 46 percent compared with Hyundai’s standard 1.6-liter GDI engine.

“Combined with Hyundai’s direct-injection technology, BorgWarner’s turbo charging expertise helps achieve a fuel efficient and responsive engine for an exhilarating driving experience,” said BorgWarner president and general manager Frederic Lissalde. “We are very pleased to expand our successful relationship with Hyundai Motor Company through our supply of advanced turbo charging technology for gasoline engines.”

Engine design

To develop a state-of-the-art engine featuring low-end torque, responsiveness, instantaneous power delivery and improved fuel economy, Hyundai matched BorgWarner’s K03 twin scroll turbo charging technology with its GDI system.

Compared with a single scroll turbocharger, twin scroll turbo charging recovers more energy from the exhaust gas and improves responsiveness even at low rpm. BorgWarner’s twin scroll turbocharger separates the exhaust gases of the cylinders and minimizes parasitic back pressures.

BorgWarner further optimizes the exhaust gas flow to the turbine wheel with an optimized channel design. Torque of 270 Nm (199 lb-ft) is available over a wide engine speed range, from as low as 1,750 rpm and up to 4,500 rpm.

In addition, BorgWarner integrated the exhaust manifold into the stainless steel turbine housing to reduce size and weight while optimizing heat energy recovery for better efficiency.
