BorgWarner Introduces New Diesel EGR Valve for Lower Emissions

BorgWarner EGR Technology Delivers Higher Force, Improved Durability with Flexible Packaging and Smaller Size

AUBURN HILLS, Mich., Sept. 20 -- BorgWarner aims to meet the future market demands for lower emissions and higher product performance with a new diesel exhaust gas recirculation (DEGR) valve with patented technology, featuring higher force, lower cost, improved durability, flexible packaging and smaller size.

"As emissions regulations continue to tighten in many countries, car manufacturers are demanding EGR solutions that will fit within a limited space in the engine compartment," said Roger Wood, President and General Manager, BorgWarner Turbo & Emissions Systems. "Building on our EGR system expertise, BorgWarner has developed innovative technologies to help diesel car manufacturers meet present and future NOx regulations while offering more flexible packaging and smaller size."

Although diesels have lower carbon dioxide emissions than gasoline engines, they have the potential to emit more smog-causing nitrogen oxides (NOx) and particulates. BorgWarner's DEGR technology effectively limits NOx formation by lowering the peak combustion temperature in the engine.

BorgWarner's DEGR valve features a DC motor actuator combined with a unique drive system to provide fast response within a smaller package. Robust, patented anti-contamination features, including effective seals and stem scraper, improve durability. Suitable for many packaging configurations, the DEGR valve can be used in both hot-side and cold-side applications, as well as in single or dual poppet systems. It can also be easily combined with an EGR cooler and cooler bypass valve.

"As the market for fuel efficient diesel vehicles continues to expand, we expect an increase in demand for existing and new EGR products," said Wood. "BorgWarner will continue to develop innovative solutions to meet and exceed ever stricter emissions regulations." The DEGR valve, which satisfies Euro V standards, is currently produced in Germany and will be manufactured in China as well. In 2009, several engine programs will be launched with a major OEM.
