    摘要: A catalyst warming apparatus for an internal combustion engine provides an appropriate combustible mixture for heating an exhaust-purifying catalyst disposed in an exhaust passage of an internal combustion engine, without providing a special pre-mixing chamber for mixing fuel and air, by burning the combustible mixture in the exhaust passage upstream of the exhaust-purifying catalyst when the exhaust-purifying catalyst is inactive. Specifically, fuel components and air discharged from the internal combustion engine are mixed into a combustible mixture in a sub exhaust-purifying catalyst disposed in the exhaust passage upstream of a main exhaust-purifying catalyst, and the resultant combustible mixture is burned upstream of the main exhaust-purifying catalyst.

    摘要: In an exhaust gas purifier for an internal combustion engine having a trap for trapping particulate matters contained in exhaust gas discharged from the internal combustion engine, the present invention aims at suppressing production of ashes and thereby preventing pressure loss associated with the clogging of the trap. In order to achieve this object, the present invention provides an exhaust gas purifier for an internal combustion engine having a trap for trapping particulate matters contained in exhaust gas discharged from the internal combustion engine, wherein the trap carries a metal which has an electronegativity equal to or lower than a predetermined content contained in fuel or lubricating oil for the internal combustion engine.
