    摘要: An exhaust purification system of an internal combustion engine, which includes: a silver-alumina-based catalyst, which is arranged in an engine exhaust system and, when an air-fuel ratio of exhaust gas is leaner than a stoichiometric air-fuel ratio, releases adsorbed NO2 at a first set temperature and adsorbed NO at a second set temperature, a secondary air feed passage configured to suppress a temperature rise of the silver-alumina-based catalyst; and an electronic control unit, that: controls the air flow through the secondary air feed passage to: when the silver-alumina-based catalyst has reached a third set temperature, suppress a temperature rise of the silver-alumina-based catalyst to maintain the silver-alumina-based catalyst near the third set temperature, and then lift the suppression of the temperature rise of the silver-alumina-based catalyst so that at least part of the NO adsorbed at the silver-alumina-based catalyst, is oxidized to NO2 to be adsorbed at the silver-alumina-based catalyst.

    摘要: A metal compound (50) able to trap a sulfur component in exhaust gas is arranged in a flow path of the exhaust gas, a property of the metal compound (50) changing along with an increase of the amount of sulfur component trapped at the metal compound (50) is measured, and the cumulative value of the amount of SOX actually contained in the exhaust gas is calculated from the measured property. On the other hand, the assumed cumulative value of the amount of SOX, assumed to be contained in the exhaust gas when assuming that fuel or oil of a sulfur concentration assumed in advance is used, is calculated. It is judged if fuel or oil with a high sulfur concentration is being used from the actual cumulative value of the amount of SOX and the assumed cumulative value of the amount of SOX.

    摘要: It is intended to construct a system for arbitrarily expressing a desired gene at a desired site in a plant. This object can be solved by providing a plant containing at least one promoter allowing a specific level of expression and a gene ligated to this promoter in an operable manner wherein the specificity of the promoter is determined based on the expression frequency of a gene containing the promoter in a cDNA database involving the promoter-containing gene. As a cDNA database, use may be made of those published in the genome project.
