Turbo Technology complies with diesel emissions regulations.July 1, 2008 -
Built with materials and coatings for compressor wheels and housings that withstand temperatures generated by recirculated exhaust gas, turbocharger can withstand harsh environment created by low-pressure exhaust gas recirculation (EGR) systems to meet emissions standards. Specialized coatings also prevent uncombusted particles from depositing on compressor, extending lifetime of turbocharger.

BorgWarner's Breakthrough Turbo Technology Improves Diesel Emissions
BorgWarner Paves the Way for Clean Diesels in the USA
AUBURN HILLS, Mich., June 19 -- 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."
BorgWarner Turbo & Emissions Systems is a leading global producer of turbochargers, exhaust gas return valves 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.
