AUBURN HILLS, Mich.,
Oct. 23, 2014 /PRNewswire/
-- BorgWarner's award-winning regulated two-stage
turbocharging (R2S®) technology boosts the 2.0-liter
diesel engine for Volvo's new Drive-E powertrain family. Available
for nearly all Volvo models, the fuel-efficient four-cylinder
engine achieves an output of 190 HP (140 kW) and a maximum torque
of 400 Nm. BorgWarner's R2S turbocharging technology helps the
engine set new standards of efficiency and performance. In the
Volvo V40 D4, the BorgWarner-boosted engine helps improve fuel
economy and reduce emissions, achieving an average fuel consumption
of 71 mpg (3.3 liters/100 km) and reducing carbon dioxide
(CO2) emissions to only 85 g/km.
"BorgWarner's R2S technology is a key enabler for downsizing
diesel engines, helping automakers comply with upcoming emissions
regulations while maintaining high engine output," said Frederic
Lissalde, President and General Manager, BorgWarner Turbo Systems.
"We appreciate our long-term partnership with Volvo Cars and are
very proud that Volvo chose BorgWarner's advanced turbocharging
technology for its new high-volume, clean diesel engine. Our many
years of turbocharger development and production experience help
automakers around the world offer fuel-efficient engines that
deliver an outstanding fun-to-drive experience."
BorgWarner's R2S turbocharging technology combines two
turbochargers of different sizes to allow the turbine and
compressor sides of the system to continuously adapt and deliver
high boost pressures over the entire engine speed range. At low
engine speeds, the entire exhaust gas flow is directed to the
smaller, high-pressure turbocharger, resulting in a quick rise in
boost pressure. At higher engine speeds, the wastegate valve opens,
and the exhaust gas is redirected to the larger, low-pressure
turbocharger. By optimizing the full engine speed range, the R2S
turbocharging system helps improve fuel economy and reduce
emissions while enhancing performance.
