has supplied its B-series turbochargers for Mercedes-Benz 12.8-liter
six-cylinder in-line Blue Efficiency Power engine.
Based on Daimler’s heavy-duty engine
generation developed for the European market, the turbocharged engine sets a
new benchmark in low emissions, improved fuel economy and increased
With a power output of 310 kW (421
hp) to 375 kW (510 hp), the engine will be used in on-road commercial vehicles
as well as off-highway vehicles. To meet demand in the U.S., BorgWarner is
supplying its turbochargers to Daimler’s, EPA10-compliant engine for
Freightliner commercial trucks.
“The new Blue Efficiency Power
engine is the result of the continuing and successful collaboration between
Daimler Trucks and BorgWarner. Around the world, commercial and off-highway
drivers will appreciate the benefits of improved performance, increased fuel
economy and reduced emissions,” said Pete Kohler, BorgWarner
President and General Manager, Turbo Systems Commercial Diesel Products.
BorgWarner’s latest B-series
turbocharger with asymmetric twin scroll turbine housing delivers improved
efficiency, high durability and excellent sealing attributes even in the harsh
working environments encountered in heavy-duty on- and off-road applications.
The asymmetric twin scroll turbine
housing incorporates two scrolls of different sizes for separate exhaust gas
routing to provide high exhaust gas recirculation rates for efficiently
reducing NOx emissions.
The smaller scroll achieves
recirculation of the exhaust gas through higher back pressure built-up in front
of the turbine. The scroll provides a high turbine output using exhaust gas
energy for optimum efficiency without being affected by the exhaust gas
recirculation. This combination provides optimum engine response and helps the
engine to comply with global emissions standards while achieving better fuel
economy and improved performance.
