Submission + - Ultra-Efficient Gas Engine Passes Test (technologyreview.com)
chudnall writes: Technology review has a story on a new gas engine injection system that promises increased efficiency of up to 50%.
The key is heating and pressurizing gasoline before injecting it into the combustion chamber, says Mike Rocke, Transonic's vice president of business development. This puts it into a supercritical state that allows for very fast and clean combustion, which in turn decreases the amount of fuel needed to propel a vehicle. The company also treats the gasoline with a catalyst that "activates" it, partially oxidizing it to enhance combustion.
