  • Exhaust gas aftertreatment systems
    Patent number: 6892530
    Abstract: A method for improving NOx conversion efficiency of a urea base SCR catalyst is presented. Since efficiency is reduced by the presence of hydrocarbons in the catalyst, the method proposes to regenerate the SCR by maintaining its temperature above the boiling point of hydrocarbons for a sufficient period of time to free up catalyst storage sites. The regeneration process is followed by over-injection of ammonia to replenish the ammonia released from the SCR catalyst due to high regeneration temperatures.

  • Brazing-filler material and method for brazing diamond
    Patent number: 6889890
    Abstract: When a diamond is brazed to a metal substrate, while obtaining a stable joining strength, a joined interface of the diamond is not eroded to provide a good joint with a beautiful view. A brazing-filler material containing at least one selected from a group consisting of gold and silver, and copper as principal components, and further containing 0.001 to 5 mass % of vanadium is used. Preferably, a vanadium content is not more than 2.0 mass %, and more preferably not more than 0.5 mass %. Using this brazing-filler material, unidirectional solidification is performed from a side of diamond to form vanadium carbide in a joined interface in a shape of islands, and thereby an interface having a beautiful view with stable joining strength can be obtained.
