Laser Technology to Help Improve Automotive Emissions

Low- Temperature Oxidation Catalysts seen as lower cost way to cut cold start-up emissions

Published: 26-Dec-2002

NASA has announced that its laser technology may soon be part of auto exhaust systems. Originally designed for satellites to measure the chemical makeup of the Earth's atmosphere, Low- Temperature Oxidation Catalysts (LTOC) will soon be available for commercial use.

Developed at NASA's Langley Research Center in Hampton, Va., LTOC technology is expected to reduce automotive pollution emissions by approximately 30 percent and the cost of after- market catalytic converters by 25 percent.

Most modern automobiles are equipped with catalytic converters that treat engine exhaust before it leaves the car. Current technology requires the exhaust to reach a high temperature before the catalytic converter begins to work.
