BorgWarner Combines Leading Turbo Technologies to Deliver More Power, Lower Emissions for Diesel V8


AUBURN HILLS, Mich., Dec. 10 / -- In a world first for automotive turbocharger products, BorgWarner's (NYSE: BWA) regulated two-stage (R2S®) turbocharger technology is combined with variable turbine geometry (VTG(TM)) to help International Engine Group's PowerStroke 6.4-liter V8 diesel engine meet stringent North American emission requirements without compromising increased horsepower and torque. The powerful diesel engine is installed in Ford's F-Series heavy-duty pickup trucks, including the F250,
F350, F450 and F550.

"Combining BorgWarner's R2S and VTG technologies results in a V8 engine with excellent acceleration, high torque and impressive power density," said Roger Wood, President and General Manager, BorgWarner Turbo & Emissions Systems. "The result is a variable two-stage turbocharged V8 engine with technology that will play a major role in the further spread of the diesel engine in the U.S. market."

A first in the American heavy-duty pickup segment, the R2S turbocharging system consists of two turbochargers of different sizes arranged in series. The smaller, high-pressure turbocharger responds spontaneously and harmoniously at low engine speeds while the larger, low-pressure unit provides an added boost at higher engine speeds. To make the infinitely variable adaptation of the turbine side to the compressor side even more efficient in every engine operating state, a turbocharger with VTG is used in the high-pressure stage - a world premiere in combination with the R2S system. Fast and precise adjustment of the VTG guide vanes is ensured by an electric actuator
motor, which BorgWarner specially developed for this turbocharger.

The two-stage system is particularly efficient at providing the high boost pressures required over a wide operating range. In order to further reduce emissions, exhaust gas recirculation (EGR) also takes place at full load, easily complying with even the strictest U.S. emissions standards. In addition, the system's compact dimensions make it possible to accommodate the entire R2S assembly in the V of the eight-cylinder diesel.

To meet growing demand for R2S turbochargers, BorgWarner Turbo & Emissions Systems has designed, built and put into operation state-of-the-art production lines for these innovative turbocharger systems at its plant in Asheville, North Carolina.

BorgWarner Turbo & Emissions Systems is a leading global producer of turbochargers and other engine air management systems for passenger cars, light trucks and commercial vehicles. These systems are designed to improve fuel economy, reduce emissions and enhance vehicle performance.
