New Technique for Cleaner, More Efficient Diesel Engines

Mark Musculus, an engine combustion scientist at Sandia National Laboratories, led a study that outlines the science base for auto and engine manufacturers to build the next generation of cleaner, more efficient diesel engines using low-temperature combustion (LTC). Diesel engines are more efficient than gasoline engines, but they still have serious pollutant emissions problems. Using new optical diagnostic techniques, Musculus and his colleagues identified the sources of key pollutants - carbon monoxide and unburned hydrocarbons - from diesel LTC engines.
