BorgWarner's Breakthrough Turbo Technology Improves Diesel Emissions

BorgWarner Paves the Way for Clean Diesels in the USA

AUBURN HILLS, Mich., June 19 /PRNewswire-FirstCall/ -- Building on the
success of variable turbine geometry (VTG(TM)) turbochargers and regulated
two-stage (R2S(R)) turbocharging systems, the experts at BorgWarner (NYSE:
BWA) have achieved another ground-breaking advancement in air management
technology, designing a turbocharger that can withstand the harsh environment
created by low-pressure exhaust gas recirculation (EGR) systems to meet the
world's strictest emissions standards. The company expects to see the
technology introduced in the U.S. in 2008 on diesel imports from two European
automakers.

"Until now, complying with stringent emissions standards -- especially
significant reductions in nitrogen oxide emissions -- has created a number of
technological challenges for diesel vehicle growth in this country," said
Roger Wood, President and General Manager, BorgWarner Turbo & Emissions
Systems. "Our patent-pending low-pressure EGR turbocharger technology can help
OEMs achieve those targets with greater reliability and performance while
protecting the environment."
One of the most effective ways to reduce nitrogen oxide emissions is
through exhaust gas recirculation to the combustion chamber. Low-pressure EGR
systems offer advantages in emissions reduction compared with high-pressure
EGR systems. However, high thermal loads and metal fatigue due to damaging
exhaust particles made it difficult to implement low-pressure EGR with
reliability. In a recent breakthrough, research and development engineers at
BorgWarner have developed new materials and coatings for compressor wheels and
housings that withstand the extreme temperatures generated by recirculated
exhaust gas. In addition, the specialized coatings prevent uncombusted
particles from depositing on the compressor, extending the lifetime of the
turbocharger.
"A focus on fuel economy continues to power the proliferation of
diesel-powered passenger vehicles around the world, and it appears that the
United States will follow the same trend," notes Wood. "At BorgWarner, our
experts have developed a number of turbocharger technologies, offering
customers tailor-made products to meet the strictest emissions standards and
helping advance growth in the clean diesel market."
