BorgWarner launches R2S turbocharging technology for diesel engines

ABR Staff Writer Published 08 March 2012

BorgWarner, a provider of components for vehicle powertrain applications, has launched the first regulated two-stage (R2S) turbocharging technology for diesel engines.

The new R2S turbocharging system has two series-connected turbochargers and features a BorgWarner compact brushless actuator controlling the wastegate.

Hyundai Motor (HMC) has used the new R2S turbocharging technology in its 5.9-liter inline six-cylinder diesel engine, which will help increase fuel economy and also helps the engine comply with Euro 5 emissions standards.

Since 2010, the 260 HP (194 kW) diesel engine has been equipped in the medium-duty urban buses and trucks in South Korea including the Aero Town, Green City and Mega Truck.

BorgWarner president and general manager turbo systems commercial diesel products Pete Kohler said the company values its partnership with Hyundai and are pleased to support optimum solutions for efficient and powerful engines in Asia's rapidly expanding commercial diesel market.

"BorgWarner's highly efficient R2S turbocharging technology enables the Hyundai 5.9-liter diesel engine to comply with stringent emission standards while improving fuel economy and performance. These are bottom line benefits that bus and truck operators around the world appreciate," Kohler said.
