Video: GM to use New Engines that Reduce Emissions
General Motors (GM) reports it is working to install a type of engine that will improve fuel efficiency by more than 15 percent and contribute to reducing U.S. foreign oil dependency. The homogenous charge compression ignition (HCCI) engine also creates less toxic emissions by burning fuel with a flameless combustion rather than using a spark plug. Today’s vehicles currently use an internal combustion engine, a model that many engineers have been trying to improve for decades without significantly increasing costs. GM officials report they are working on a production model that uses an HCCI engine, however, an exact date of availability has not been specified. Watch Video
