Technology Focus, In Pursuit of New Engine Dynamics

摘要

Transportation accounts for 65 percent of U.S. oil consumption. More efficient vehicle engine designs would reduce U.S. dependence on foreign oil and help mitigate global climate change caused by carbon dioxide emissions. And cleaner engines would contribute to reducing toxic pollutants in the atmosphere, such as nitrogen oxide, hydrocarbons, and carbon monoxide. One promising technology, the homogeneous charge compression ignition engine, has potential for high efficiency and low emissions.
