Catalysts, Computers, and Cars: A Growing Symbiosis

摘要: Catalytic converters not only reduce air pollution from automobiles, but also improve fuel economy by allowing the engine to operate closer its minimum consumption. The characteristics of automobile emissions are examined, and mechanism three-way catalysis is described. application automatic, computerized sensors controls efficiency effectiveness catalytic discussed.
