SwRI’s HEDGE Technology Eliminates Low-Speed Pre-Ignition in Highly Boosted Engines

Green Car Congress

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.

Opinion: Cars and Toxic Substances

Clean Fleet Report

Burning gasoline, wood, charcoal or other fuel produces CO, among other pollutants. Well, we know what internal combustion cars do—they burn fuel, which goes out the exhaust. This might happen because of an old or damaged exhaust system that allows the air conditioning unit to bring in the CO, which is supposed to go out.
