Cooled EGR Cuts Fuel Consumption by 5-30%

At the China International Auto Tech Forum held July 8th in Beijing, Christopher J. Chadwell, a Research & Development manager from Southwest Research Institute located in the state of Texas in the United States, introduced a cutting edge engine technology to improve fuel efficiency and cut emissions.

The Southwest Research Institute (SwRI) is an independent nonprofit applied research and development organization. SwRI has previously completed 2 consortium projects that have resulted in intellectual property and technologies that have been integrated into today’s production engines.

The new engine technology that was introduced at the Auto Tech Forum is known as Cooled Exhaust Gas Recirculation (EGR). Recent studies performed by engineers at SwRI have examined that (EGR) can play a significant role in reducing, or even eliminating, sources of inefficiency in gasoline engines. Implementing Cooled EGR engine technology has the possibility to reduce fuel consumption from 5 percent to up to 30 percent.

With many governments around the world regulating CO2 emissions, Cooled EGR technology will possibly be able to serve a significant role in improving the efficiency of gasoline engines and meeting the needs of developing nations around the globe. This technology is of great interest to nations like China where the pollution is a significant problem for residents for the forum host city Beijing. With the combined efforts of Governments around the world and Organizations like the SwRI harmful CO2 emissions and overconsumption of fuel will become less of a global issue.
