  • Publication number: 20240068422
    Abstract: An upstream integrated value is an integrated value of a difference obtained by subtracting an upstream gas temperature at a starting point in time of integration from the upstream gas temperature after starting of the internal combustion engine. A downstream integrated value is an integrated value of a difference obtained by subtracting a downstream gas temperature at the starting point in time of the integration from the downstream gas temperature after the starting of the internal combustion engine. An anomaly diagnosing process obtains an anomaly determination result indicating that the exhaust purification device is in a removed state when a deviation between the upstream integrated value and the downstream integrated value is smaller than a reference level. The determination threshold is higher than a dew point.

  • Patent number: 5605892
    Abstract: An aqueous agent comprising at least one arginine amide selected from the group consisting of (2R,4R)-4-methyl-1-[N.sup.2 -((RS)-3-methyl-1,2,3,4-tetrahydro-8-quinolinesulfonyl)-L-arginyl]-2-piper idinecarboxylic acid, monohydrate thereof and pharmacologically acceptable salts thereof, and at least one compound selected from the group consisting of cyclodextrin and caffeine; a method for improving the solubility of arginine amide in water, comprising adding at least one compound selected from the group consisting of cyclodextrin and caffeine; and a method for stabilizing arginine amide in water, comprising adding caffeine. According to the present invention, the solubility of arginine amide in water can be enhanced to, for example, a concentration permitting inhibition of fibrin formation at the time of entoptic operation. In addition, the stability of arginine amide in water can be enhanced with less irritation of the eye.
