AUBURN HILLS, Mich.,
July 21, 2015 /PRNewswire/
-- BorgWarner provides its award-winning regulated two-stage
(R2S®) turbocharging technology for Volkswagen's new
high-performance diesel engine. Engineered to comply with the
Euro 6 emissions standard, the
2.0-liter four-cylinder engine is the most powerful diesel engine
in its class. Providing an output of 240 HP (176 kW) and a maximum
torque of 369 lb.-ft. (500 Nm), it achieves an average fuel economy
of 44 mpg (5.3 liters/100 km). Powered by BorgWarner's optimized
turbocharging technology, the diesel engine debuted in the VW
Passat and sets new standards for efficiency and performance.
"We are pleased to expand our long-term partnership with the
Volkswagen Group by delivering our regulated two-stage
turbocharging technology for this powerful, downsized diesel
engine," said Frederic Lissalde, President and General Manager,
BorgWarner Turbo Systems. "BorgWarner's leading turbocharging
technologies help automakers deliver powerful performance."
BorgWarner's R2S turbocharging system consists of two
series-connected turbochargers and features a variable turbine
geometry (VTG) turbocharger for the high-pressure stage combined
with a larger B03 water-cooled turbocharger optimized for
low-pressure exhaust gas recirculation (LP EGR). The low-pressure
EGR is captured downstream of the exhaust emission control system
and then mixed with the fresh air upstream of the compressor of the
low-pressure stage. BorgWarner uses a special protective coating on
the turbocharger compressor wheel to withstand the extreme loads
and the corrosive particles. Controlled by an electric actuator,
BorgWarner's VTG turbocharger responds quickly at low engine
speeds, resulting in a rapid rise in boost pressure for nearly
instant acceleration. As the engine speed increases, both
turbochargers work together, gradually shifting to the larger,
low-pressure turbocharger. At higher engine speeds, all of the
gases flow directly to the larger B03 turbocharger, maintaining
smooth power delivery at higher speeds. By combining two
series-connected turbochargers of different sizes, BorgWarner's R2S
technology provides high boost pressures over the entire engine
speed range.
