Southwest Research Institute (SwRI) has launched its third cooperative research program aimed at developing a high-efficiency gasoline engine for the light-duty automotive and medium-duty engine markets. The four-year program, called HEDGE-III (High-Efficiency Dilute Gasoline Engine), will continue the work done in HEDGE-II, which developed dedicated-EGR technology that achieved nearly 42% thermal efficiency from a 2.0-L engine. This engine, using SwRI’s D-EGR technology, achieved roughly the same fuel consumption as a 2.0-L diesel, but with the potential for ultra-low emissions and high specific power that typically are associated with a gasoline engine. HEDGE-III will continue investigating high-efficiency concepts of Low Pressure Loop (LPL) EGR and D-EGR while developing tools for improved flame modeling and improved knock prediction for high-dilution gasoline engines. Work will also continue on advanced ignition and boosting systems. However, it will begin to shift the emphasis to a more general examination of high-efficiency technologies with less direct emphasis on cooled EGR and more on interactions with dilute and variable-valvetrain technology, and extending EGR to gasoline direct-injection and alternative-fuel engines such as natural gas. For more information about HEDGE, contact Dr. Terry Alger at (210) 522-5505, fax (210) 522-2019, or e-mail at talger@swri.org.
