Southwest Research Institute (SwRI) has successfully demonstrated that its HEDGE (High-Efficiency, Dilute Gasoline Engine) technology, using cooled exhaust gas recirculation (EGR) and advanced ignition systems, suppresses low-speed pre-ignition in turbocharged gasoline direct-injection engines.

Using a 2007 base vehicle, the committee estimated the potential fuel savings and costs to consumers of available technology combinations for three types of engines over that timeframe: spark-ignition gasoline, compression-ignition (CI) diesel, and hybrid.

Replacing spark-ignition engines with diesel engines and components would yield fuel savings of about 37% at an added cost of approximately $5,900 per vehicle, and replacing spark-ignition engines with hybrid engines and components would reduce fuel consumption by 43% at an increase of $6,000 per vehicle.

Stoichiometric gasoline direct-injection technology: injects fuel at high pressure directly into the combustion chamber to improve cooling of the air/fuel charge within the cylinder, which allows for higher compression ratios and increased thermodynamic efficiency. Stoichiometric Gasoline Direct Injection (GDI): 44% for cars, 56% for trucks.
