摘要: An exhaust gas purification device suppresses a pressure loss increase and includes a honeycomb substrate and inflow cell side catalyst layer. The substrate includes a porous partition wall defining several cells extending from an inflow side end surface to an outflow side end surface. The cells include an inflow and outflow cell adjacent across the wall. The inflow cell has an open inflow side end and sealed outflow side end. The outflow cell has a sealed inflow side end and open outflow side end. The catalyst layer is on an inflow cell side surface in an region extending from the inflow side end positioned 10% or more of the partition wall length. At this position, a filled portion of the inflow cell side catalyst layer pores are 40% or less. The pores are present to a depth of 50% of a thickness of the partition wall.

摘要: The disclosure provides a platinum-containing three-way conversion (TWC) catalyst, and a system for treating an exhaust gas stream from a gasoline engine using the TWC catalyst. The system is configured to introduce controlled quantities of hydrogen gas into the exhaust gas stream upstream of the platinum-containing TWC catalyst article during a cold-start period. Further provided are related methods of treating such exhaust streams. Such systems and methods are useful in reducing a level of one or more of hydrocarbons, carbon monoxide, and nitrogen oxide in a gaseous exhaust stream from a gasoline engine.
